Caltech's extraordinary faculty and students are expanding our understanding of the universe and inventing the technologies of the future, with research interests from quantum science and engineering to bioinformatics and the nature of life itself, from human behavior and economics to energy and sustainability. Caltech is small but prizes excellence and ambition. The contributions of Caltech's faculty and alumni have earned national and international recognition, including 46 Nobel Prizes. The Institute manages the Jet Propulsion Laboratory (JPL) for NASA, sending probes to explore the planets of our solar system and quantify changes on our home planet; owns and operates large-scale research tacilities such as the Seismological Laboratory and a global network of astronomical observatories, including the Palomar and W. M. Keck Observatories; and cofounded and co-manages LIGO, which, in 2016, observed gravitational waves for the first time. The Institute has one of the nation's lowest student-to-faculty ratios, with 300 professorial faculty members offering a rigorous curriculum and access to varied learning opportunities and hands-on research to approximately 1,000 undergraduates and 1,400 graduate students. Caltech is an independent, privately supported institution with a 124-acre campus located in Pasadena, California. MISSION The mission of the California Institute of Technology is to expand human knowledge and benefit society through research integrated with education. We investigate the most challenging, fundamental problems in science and technology in a singularly collegial, interdisciplinary atmosphere, while educating outstanding students to become creative members of society. HISTORICAL SKETCH In September of 1891, Pasadena philanthropist Amos G. Throop (pronounced Troop) established Throop University, the institution that would eventually become Caltech. Throop University opened its doors with 31 students and a six-member faculty. Throop might have remained simply a good local school had it not been for the arrival in Pasadena of astronomer George Ellery Hale. The first director of the Mount Wilson Observatory, Hale became a member of Throop's board of trustees in 1907 and began molding the school into a first-class institution for engineering and scientific research and education. Hale would be joined later by chemist Arthur A. Noyes and physicist Robert A. Millikan. By 1920, the school was renamed the California Historical Sketch 8 Institute of Technology, and the enrollment was nine graduate students and 359 undergraduates, with a faculty of 60; a decade later there were 138 graduate students, 510 undergraduates, and a faculty of 180. At the present time there are nearly 1,000 undergraduates, 1,400 graduate students, and some 300 professorial faculty and more than 600 postdoctoral scholars. Caltech has more than 24,000 living alumni all over the world, many of them eminent in their fields of engineering, science, law, medicine, academia, and entrepreneurship. Caltech's divisional structure, which began to coalesce in 1926, today comprises the Division of Biology and Biological Engineering (BBE); the Division of Chemistry and Chemical Engineering (CCE); the Division of Engineering and Applied Science (EAS); the Division of Geological and Planetary Sciences (GPS); the Division of the Humanities and Social Sciences (HSS); and the Division of Physics, Mathematics and Astronomy (PMA). To learn more about Caltech's history and the people behind the Institute's success, visit library.caltech.edu/archives/home EDUCATION AND RESEARCH Students at Caltech work toward undergraduate and graduate degrees alongside their intellectual equals in an academic environment that emphasizes interdisciplinary teamwork, critical thinking, mutual support, and a deep understanding of core concepts and principles across fields. Caltech students, faculty, and postdoctoral scholars are addressing fundamental scientific questions and pressing societal challenges. Together, they are expanding our understanding of the universe, shifting paradigms, launching new fields, and inventing the technologies of the future. Caltech is home to more than 50 research centers and institutes. Some 90 percent of Caltech undergraduates participate in research during their time here. UNDERGRADUATE PROGRAMS AND RESEARCH Caltech offers undergraduates 27 majors (called "options") and 17 minors across the six academic divisions. The most popular options are computer science, chemical engineering, electrical engineering, mechanical engineering, and physics. Caltech also offers interdisciplinary programs in applied physics, biochemistry, bioengineering, computation and neural systems, control and dynamical systems, environmental science and engineering, geobiology and astrobiology, geochemistry, and planetary astronomy. The Institute offers the opportunity for qualified students to engage in research early in their careers under the supervision of a faculty member. There are four principal avenues for undergraduate research: the senior thesis, the Summer Undergraduate Research Fellowships (SURF) program, research courses for academic credit, and research for pay under a faculty member's grant or contract. General Information The senior thesis involves original research under the mentorship of a faculty member, an effort that develops research, writing, and presentation skills that together provide an excellent preparation for future graduate studies and/or professional life. The SURF program provides continuing undergraduate students the opportunity to work on an individual research project in a tutorial relationship with a mentor, usually a member of the Caltech/JPL research community, but occasionally a faculty member at another college or university. The work is carried out during a 10-week period in the summer, after which SURF students submit a written report describing the project, methods, and results of their work. Most options offer undergraduate research courses in order to encourage research participation during the academic year; students should consult listings and descriptions of opportunities. In some circumstances, faculty will hire students to conduct research. Students should discuss this option with a prospective mentor. Students with work-study financial aid should also contact Caltech's Career Advising and Experiential Learning (CAEL) about how to apply funding to research positions. Learn more about undergraduate programs and research at sfp.caltech.edu/. GRADUATE PROGRAMS AND RESEARCH Students can enroll in Master of Science, Degree of Engineer, Doctor of Philosophy, BS/MS, and MD/PhD degree programs; the majority of graduate students are enrolled in the PhD program. The academic work of the Institute is organized into six divisions: Biology and Biological Engineering (bbe.caltech.edu); Chemistry and Chemical Engineering (cce.caltech.edu); Engineering and Applied Science (eas.caltech.edu); Geological and Planetary Sciences (gps.caltech.edu); Humanities and Social Sciences (hss.caltech.edu); and Physics, Mathematics and Astronomy (pma.caltech.edu). Graduate study at the Institute is divided further into a number of individual graduate options (degree programs), which are supervised by those professors whose interests and research are closely related to the area of the option. Entering graduate students are admitted into one of these options. The most popular options for graduate work are chemistry, physics, electrical engineering, and biology. Learn more at gradoffice.caltech.edu. ACADEMIC PARTNERSHIPS Caltech maintains an array of external partnerships with other institutions in Southern California. These partnerships provide pre-med students with opportunities to work in area hospitals and train with practicing clinicians; allow students to participate in ROTC through a joint program with USC; and offer a 3/2 dual degree for students from 13 select liberal-arts colleges. Caltech undergraduate students can cross-register at Occidental College and Art Center College of Design, and the Institute maintains relations with research partners such as the Scripps Institution of Oceanography at UCSD. Undergraduate students can also study abroad in Cambridge, Education and Research 9 10 Copenhagen, Edinburgh, London, Paris, Melbourne, or the University of Chicago during their junior or senior years For graduate students, joint programs between Caltech and both the USC Keck School of Medicine and the UCLA David Geffen School of Medicine grant MD/PhD degrees. FACULTY RESEARCH The contributions of Caltech's faculty have earned national and international recognition. Caltech was elected to the Association of American Universities (AAU) in 1934 and remains a research university with "very high" research activity, primarily in STEM fields. Research is central to Caltech, and the Institute manages over $400 million in sponsored awards annually. Its largest federal funding agencies are the National Aeronautics Space Administration (NASA), National Science Foundation (NSF), Department of Health and Human Services, Department of Defense, and Department of Energy. More than a quarter of Caltech's active and emeritus faculty members are members of the National Academy of Sciences, Engineering, and Medicine and/or are fellows of the American Academy of Arts and Sciences. Caltech receives more invention disclosures and holds more patents per faculty member than any other university in the United States. POSTDOCTORAL AND SENIOR POSTDOCTORAL SCHOLARS More than 550 early-career scientists and engineers conduct research at Caltech as postdoctoral scholars. In addition, JPL hosts postdoctoral scholars whose studies cover many aspects of Earth, planetary, astrophysical, and technology research. All scholars work under the supervision of professorial faculty members or JPL researchers.

The original four - Blacker, Dabney, Fleming, and Ricketts— were built in 1931 from the plans of Mr. Gordon B. Kaufmann, in the Mediterranean style to harmonize with the adjacent Athenaeum. The other three, designed by Smith, Powell and Morgridge, were completed in 1960, and are named Lloyd, Page, and Ruddock. Each of these seven residences is a separate unit with its own dining room and lounge, providing accommodations for between 65 and 100 students, depending on the facility. Each has its own elected officers; a long history of shared governance gives students a great deal of influence over their living environments. Residential life coordinators (RLCs) are specially trained full-time university employees specializing in college student development, community building, counseling, and crisis intervention. The RLCs supervise the resident associates (RAs) on programming and overall student wellness. The RLCs also assist Housing with the management and daily operations of the residences. Each residence has one or more RA, who are typically graduate students. Mail is delivered daily to the student mailboxes. Students should use their mailbox number, California Institute of Technology, Pasadena, CA 91126, to facilitate handling of mail at the campus post office. For more information, please visit housing.caltech.edu. Avery House Made possible by a gift from trustee R. Stanton Avery, this undergraduate residence and innovative residential complex was designed by Moore, Ruble, Yudell, and completed in September 1996. Located at the north end of the campus, Avery has an RLC, two RAs, two faculty apartments, and rooms for about 136 undergraduates. Its dining facilities, meeting rooms, lounges, and library are designed to encourage informal faculty-student interaction and to attract all members of the campus community to join in this interaction. Avery hosts programs and social events that facilitate involvement between residents and faculty in residence. General Information Bechtel Residence Established in the fall of 2018 and located at the northeast edge of campus, the Bechtel Residence is the first residence to open on campus since 1996. Bechtel is named in honor of Caltech life trustee Stephen D. Bechtel, Jr., the founder of the S. D. Bechtel Foundation. The 95,000-square-foot residence is a multigenerational residence open to all undergraduates with: 211 student bedrooms arranged as singles and in suites; six RA and one RLC apartments; and two faculty-in-residence apartments. Bechtel was intentionally designed to provide the community with the greatest flexibility to maximize space as well as to encourage broader interaction, engagement, and residential life programming among residents. The facility includes three kitchens; eight common areas/study rooms; six laundry rooms; a 400-seat dining hall and servery; and support spaces. Summer Housing Caltech will extend a License Contract to those individuals who satisfy the following criteria: (1) they have been approved by the Housing Office and the Undergraduate Dean's Office; (2) they are eligible to enroll for the upcoming Fall Term by no later than the June UASH meeting; and (3) they are in good standing with both the Bursar's Office and the Institute overall. Individuals must satisfy this criteria for the duration of the License Contract. If a Caltech student becomes ineligible to enroll, or is no longer in good standing with the Bursar's Office, or in good standing with the Institute, or in good standing with their Institute-approved summer program, their License Contract will be automatically revoked. UASH meeting dates and petition deadlines can be found at registrar.caltech.edu/current-students/uash. STUDENT RESOURCES AND ACTIVITIES Hameetman Center The Hameetman Center, which opened in 2019, is a new campus center built on the site of the former Winnett Student Center. The Hameetman Center replaces Winnett as Caltech's central community gathering place. The 24,000-square-foot two-story center is named in honor of the Hameetman Foundation and Caltech trustee Fred Hameetman (BS '62) and his wife, Joyce, who provided the initial funding to initiate the design of the reimagined campus hub. It features a large public lounge, an expanded Red Door Marketplace, the Caltech Store, music rehearsal facilities, student club rooms, a multipurpose room, and a conference room. The rehearsal facility is made possible thanks to a gift from Emeritus Professor of Theoretical Physics Steven Frautschi and his wife, Mie. Residential Experience The Office of Residential Experience (ORE) has responsibility for the oversight of Caltech's residential programs, including programs carried out in the undergraduate houses, graduate student residences, and the Bechtel and Marks-Braun communities. The ORE works collaboratively with the Residential Life Coordinators, Resident 15 Student Life 16 Associates, the Interhouse Committee, and other groups to ensure that student leaders in all our residential communities are trained and that there are programs in place to support their development. This is part of the shared governance that is central to the Caltech residential experience. The residence experience also includes member of the faculty who live in the undergraduate residences. The Faculty in Residence (FIR) Team establishes an academic life and culture in Bechtel and Avery House. FIRs bridge the classroom experience by hosting regular conversations over dinner and develop specialized academic programing, which can include: extracurricular activities, tours and excursions, cooperative community service projects, special events, and guest speaker programs. All residences and houses, including all their activities and programs, are expected to comply with Institute policies, Student Affairs policies, and the Caltech Code of Conduct. Potential Policy or Code of Conduct violations by a house or residence will be referred to the Caltech Routing committee. If the Routing Committee determines that the incidents) is part of a Residential or House program or activity, it will be referred to ORE for further action. In this case, the Assistant Vice President for Student Affairs and Residential Experience (AVP) or designee, will either (a) manage the situation directly with the community so the concerns can be addressed, or (b) initiate an investigation into the incident. If an investigation is conducted, the investigators will report their findings to the AVP who will make a decision concerning whether any violations occurred and any consequences that may be imposed. The decision of the AVP may be appealed to the Vice President for Student Affairs within 10 days of the decision. During the investigation, the AVP can suspend activities of the house or residence until further notice if deemed necessary for the health, safety, or the other benefit of the community. A range of outcomes may be considered as consequences to the house or residence if the group is found to have engaged in a policy violation. Possible sanctions including community education and/or suspension of the activity or event. Examples of events that warrant a response include an unregistered event or party, mistreatment of members, and hazing. If the potential situation also includes a potential policy violation involving an individual students), the students) will be referred to the appropriate Dean's office and may be subject to disciplinary action. The Student Activities Center The SAC is located in the basement of the south undergraduate housing complex and is open for student use 24 hours a day. The SAC provides office space for the officers of the undergraduate student government, working space for student publications, rehearsal space for musical activities, and space for many other student-oriented functions. Whether students are interested in music, publications, student government, gaming, photography, or simply finding a room for their group to meet in, the SAC will probably have what is needed. The General Information center also houses the South House laundry room and has several club rooms, a small library, a shop, and a movie screening room-most are open 24 hours. Faculty-Student Relations Faculty-student coordination and cooperation with regard to campus affairs are secured through the presence of students on faculty committees, by faculty-student conferences, and by other mechanisms. First-Year Advisers Each member of the first-year class is assigned a faculty adviser and is a member of a small advising group. The adviser follows the first-year student's progress and provides advice on any questions or problems that the student may have. Option Advisers Each member of the three undergraduate upper classes is assigned an option adviser, a faculty member in the option in which the student is enrolled. The adviser takes an interest in the student's selection of courses and progress toward a degree, and, eventually, in assisting the student toward satisfactory placement in industry or in graduate school. Normally, the association between student and adviser is established before the beginning of the sophomore year and continues through graduation. Athletics, Physical Education, & Recreation (APER) Caltech supports an extensive program of competitive athletics.

Student-faculty conferences are held every other year and serve to promote communication mainly around academic topics. Graduate Student Council The Graduate Student Council (GSC) is the student government for Caltech graduate students. It is the mission of the GSC to maximize the quality of life for the graduate student community at Caltech. The GSC Board of Directors interacts with the Institute's administrative bodies and is formed of subcommittees dedicated to academic support, advocating graduate student issues, sharing student news, and organizing social events. General Information Student Leadership Expectations Graduate and undergraduate student leaders who are in either elected or appointed positions must be enrolled and in good standing with the Institute. Honor System The Honor Code, embodied in the phrase "No member shall take unfair advantage of any other member of the Caltech community," is the fundamental principle of conduct for all students and extends to all phases of campus life, including scholastic and extracurricular activities, relations among students, and relations between students and faculty. The Honor System is the most important tradition of the undergraduate student body. The Board of Control (Board), which is composed of elected student representatives, is charged with monitoring the academic Honor System for undergraduates, investigating course work violations, and making recommendations to the dean of undergraduate students. The purpose, composition, duties, and procedures of the Board, as well as the roles and responsibilities of the deans, faculty, vice president for student affairs, complainants (students reporting suspected violations), respondents (those against whom an allegation of an academic Honor System violation is made), witnesses, and other participants in the process, are set forth in Article XIII of the Associated Students of the California Institute of Technology bylaws. The Conduct Review Committee, composed of students, faculty, and staff, hears cases involving non-academic Honor Code and Institute policy violations for undergraduate students, and also makes recommendations to the dean. At their discretion, the dean of undergraduate students, or their designee, may directly handle a matter also involving the Honor System, the Code of Conduct, and Institute Policies for undergraduate students. The Honor Code Handbook, a resource for undergraduate students, is available online at deans.caltech.edu/HonorCode. The Honor System is also an important part of graduate student life. The dean of graduate studies is responsible for reviewing and making decisions concerning alleged Honor Code violations with respect to course-work. The Graduate Honor Council (GHC) serves as a consultative resource to the dean. At their discretion, the dean of graduate studies may request that the GHC investigate and hear a case, and provide its recommendations to the dean for final review and decision. All Members of the Graduate Honor Council must be in good standing with the Office of Graduate Studies and must attend a formal training before they may serve on a case. Examples of Honor Code violations include, but are not limited to, plagiarism, violations of the collaboration policy in a class, and/or using resources that were strictly prohibited for homework and/or exams. Incidents that are not handled by the dean of graduate studies include accusations of research misconduct, which are handled by the Office of Research Compliance; grade disputes, which are handled by the office of the provost. Institute Policy violations are handled by the office of the dean of graduate studies or the appropriate administrative 19 Student Life 20 organization. Student Body Publications The publications of the student body include a weekly paper, The California Tech; an undergraduate research journal, CURJ; a literary magazine, Totem; a student handbook, the Little t, which gives a survey of student activities and organizations and serves as a campus directory; a yearbook, Big T; an online undergraduate research opportunities handbook, UROH; and Caltech Letters, an online campus publication designed to let students talk about their research and their viewpoints on science with the broader world. These publications, staffed entirely by students, provide an opportunity for interested students to obtain valuable experience in creative writing, photography, artwork, reporting and editing, advertising, and business management. Performing and Visual Arts The Institute provides directors and facilities for choirs, concert band, jazz band, symphony orchestra, numerous chamber music ensembles, guitar classes, a theater program, ceramics and studio arts classes. These activities are centered in the Music and Theater Arts houses on Hill Avenue along the eastern edge of campus.

If an investigation is conducted, the investigators will report their findings to the AVP who will make a decision concerning whether any violations General Information occurred and any consequences that may be imposed. The decision of the AVP may be appealed to the vice president for student affairs within 10 days of the decision. During the investigation, the AVP may suspend the club's recognition and planned activities, if deemed necessary, for the health, safety, or other benefit of the community. A range of outcomes may be considered as consequences to the club if the group is found to have engaged in a policy violation. Possible sanctions examples include education, suspension of some or all of the group's privileges, or loss of their recognition status with the Institute.

AUDITING COURSES Persons affiliated with the Institute may audit courses if they obtain the consent of the instructor in charge of the course, and the dean of undergraduate students or dean of graduate studies, as appropriate, and pay the required fee (contact the Bursar's Office for audit fee). The fees are nonrefundable. Auditing forms may be obtained in the Registrar's Office. Regularly enrolled students and members of the faculty are not charged for auditing. Auditing forms are not required, but the instructor's consent is necessary in all cases. No grades for auditors are reported to the Registrar's Office, and no official record is kept of the work done. GRADES AND GRADING All permanent grades recorded for first-year students during the first and second terms they are enrolled will be either P, indicating "passed," or F, indicating "failed." The temporary grade of I ("incomplete") may be used as it is for other students. The temporary grade of E may be given to first-year students as described below for other students. It may also be used in a continuing course if the performance of the first-year student concerned is not significantly below the current passing level, and if the student is maintaining a steady and substantial improvement; an E given for this reason will be automatically changed to a P if the first-year student earns a P for the following term, and will change to an F if the student receives an F for General Information the following term. The grade may not be used in this way for two successive terms nor for the last term of the course. If a first-quarter or second-quarter first-year student is enrolled in a course in which the instructor gives letter grades, the registrar will record P for all passing grades. No grades given to a first-year student during the first and second quarter in which they are enrolled will be used in computing the cumulative grade-point average. For all students beyond the first and second quarters of their first year (as a first-year student), graduate and undergraduate, letter grades will ordinarily be used to indicate the character of the student's work: A, excellent; B, good; C, satisfactory; D, poor; E, conditional; F, failed; I, incomplete. P may also be used as described below under Pass/Fail Grading. In addition, grades of A+ and A-, B+ and B-, C+ and C-, and D+ may be used. In any situation in which no grade is reported, the grade shall be assumed to be F. Failed. Means that no credit will be recorded for the course. The units, however, count in computing the student's grade-point average, unless the course was taken on a pass/fail basis. The student may register to repeat the subject in a subsequent term and receive credit without regard to the previous grade, the new grade and units being counted as for any other course, but the original F and units for the course remain on the record. Grades other than E, I, and W are assumed to be based on work completed and evaluated at the time of grade submission. E and I Grades E Grades. At their discretion, instructors may give students who have not completed their work for a course by the end of the term a grade of E. The grade E indicates deficiencies that may be made up without repeating the course. If the instructor does not specify a date on the grade report sheet for completion of the work, students receiving an E will have until Add Day of the following term to complete their work for that course. Instructors may, however, require the work for the course to be completed by an earlier date. In addition, students should be aware that E grades can impact ability to meet eligibility requirements. If an E grade impacts a student's academic standing, the grade may be due by the first day of classes. See section Scholastic Requirements for additional information. If a student receives an E and does not complete the work by the date specified by the instructor or by Add Day (or a different date specified by the instructor), the grade will be changed to an F. Adequate time must be afforded to instructors to grade the work and to submit the final grade to the registrar. It is the responsibility of a student receiving an E to confirm that the registrar has recorded the terms for satisfying the completion of the work in the course. With the written permission of the instructor, a student may extend the E grade past Add Day of the following term, but doing so will cause an additional E grade to be registered. Each additional extension of the E will be until the date specified by the instructor or until Add Day of the following term, but in each case will require the 29 Grades and Grading 30 written permission of the instructor and the registering of an additional E grade. E Count Limitations. After an undergraduate student has been awarded the grade of E six times, they are not eligible to receive E grades in any subsequent term. A petition for an E in a subsequent term may be approved by the Undergraduate Academic Standards and Honors (UASH) Committee in an exceptional case. Such a petition requires the support of the instructor and the dean or associate dean of undergraduate students. / Grades. The grade I is given only in case of unexpected sickness or other emergency, occuring near the end of the term, that impedes the completion of the work in the class. An I grade is not intended to allow students to make up missed work from the majority of the term. If a student has not completed the majority of the work, they are not eligible for an incomplete and they will be advised to late drop the class or take a leave. It is given at the discretion of the instructor, after approval by the dean or associate dean of students or the dean of graduate studies. If a student is seeking an I grade due to a severe exacerbation or onset of a disability that occurred near the end of the term, they should contact Caltech Accessibility Services for Students (CASS) at cass@caltech.edu. The time period within which the grade of I is to be made up should be indicated on the grade sheet, or students receiving an I will have until Add Day of the following term to complete their work for the course. In addition, students should be aware that I grades can impact ability to meet eligibility requirements. If an I grade impacts a student's academic standing, the grade may be due by the first day of classes. See section Scholastic Requirements for additional information. Students receiving grades of E or I should consult with their instructors, and one of the deans, at the time of issue regarding the work required and the time allowed. This time should, in most cases, coincide with the date fixed in the calendar for removal of conditions and incompletes (Add Day), and in fact if no other time is specified, this date will be assumed. However, except under extraordinary circumstances, the time for the completion of the work will not be extended beyond one year after the date in which the grade of E or I was given. In the absence of an earlier deadline, an E will turn into an F one year after the date on which the E was given, and an I grade will turn into a W (standing for "withdrawn") one year after the date on which the l grade was given. Waiving of this one year rule is done in only the most exceptional of circumstances and requires the agreement, before that one year anniversary, of the dean of undergraduate students, chair of UASH, and executive officer of the department in which the course was taken. Grades of E and I shall not be considered in calculating a student's grade-point average. General Information Petitions and Exceptions Once recorded, a grade will only be changed on the basis of error. Such a change may be made only with the approval of the Undergraduate Academic Standards and Honors Committee or of the Graduate Studies Committee, whichever has jurisdiction. Petitions by undergraduate students for late drops (i.e., requests to drop a course after Drop Day) will be considered by the UASH Committee, but will only be approved if circumstances beyond the student's control prevented them from dropping a course or courses by the posted deadline. Such petitions must be submitted before the end of the term following the term when the course was taken, or within the first term of return, if the student is on leave in the term following the term when the course was taken. If approved, a W will be recorded on the student's transcript in place of a grade for that course. W's will not be included in the computation of the student's grade-point average. Courses will be expunged from the student's record only in exceptional circumstances, at the discretion of the UASH Committee. Petitions from graduating seniors submitted later than the first UASH meeting following graduation (which normally takes place shortly after graduation) will not be accepted for consideration, except to correct an error by the Institute. Grade-Point Average Grade-point average is computed by dividing the total number of credits earned in a term or an academic year by the total number of units taken in the corresponding period. Units for which a grade of F has been received are counted, even though the course may have subsequently been repeated. Grades of P or F obtained in courses graded on a pass/fail basis are not included in computing grade-point average. Each course at the Institute is assigned a number of units corresponding to the total number of hours per week devoted to that subject, including classwork, laboratory, and the normal outside preparation. Credits are awarded as shown in the table below. 31 No. of Units A+ A- B+ B B- |C+ | C F 1 4 4 4 3 3 3 2 2 2 1 2 9 8 7 7 6 5 5 4 3 3 2 0 3 13 12 11 10 9 7 6 5 4 3 0 4 17 16 15 13 12 11 9 8 7 5 4 5 22 20 18 17 15 13 12 10 8 7 5 6 26 24 22 20 18 16 14 12 10 8 6 0 7 30 28 26 23 21 19 16 14 12 9 7 10 Grades and Grading 32 8 35 32 29 27 24 21 19 16 13 11 8 9 39 36 33 30 27 24 21 18 15 12 9 10 43 40 37 33 30 27 23 20 17 13 10 0 11 48 44 40 37 33 29 26 22 18 15 11 0 12 52 48 44 40 36 32 28 24 20 16 12 13 56 52 48 43 39 35 30 26 22 17 130 14 61 56 51 47 42 37 33 28 23 19 140 15 65 60 55 50 45 40 35 30 25 20 15 0 Pass/Fail Grading, the following regulations apply • First-quarter and second-quarter first-year students receive pass/fail grades in all courses by virtue of their classification as first-year students by an admissions committee or, for students whose status after the first year is uncertain, by the Undergraduate Academic Standards and Honors Committee. • All other students, undergraduate and graduate, in courses with numbers under 200 will receive letter grades unless the course is designated "graded pass/fail" or unless, when it is allowed, the student submits a change to the course's grading scheme on or before Drop Day. • In courses with numbers 200 or greater that are not designated either "graded pass/fail" or "letter grades only," the instructor may decide separately for each student what class of grades to use. • All research courses shall be designated "graded pass/fail." All reading courses, seminar courses, or other courses that do not have a formal class structure shall be designated "graded pass/fail" unless the option secures an exemption from the Curriculum Committee or the Graduate Studies Committee and from the Faculty Board. • A grade on the pass/fail system should be P if it would have been a D or better on the letter grade system. (Note that there is no D-grade.) The standards of failure in courses in which only pass/fail grades are used should be the same as they would be if the course were letter graded. • Any instructor may, at their discretion, specify prior to registration that their course, if not classified by the above regulations, is to be graded on a "letter grades only" basis or is to be graded pass/fail only, subject to possible review by the responsible option. The registrar must be notified of such specification two weeks before the beginning of registration. (Note: If the grading scheme is changed during the term, it is changed for everyone.) • Each term, any student may select, subject to requirements imposed by the student's option, two elective courses in which General Information they are to be graded on a pass/fail basis if the course is not designated as "letter grades only" and is not specifically required for the degree in their option. To make this election, a student must submit a change to the course's grading scheme in REGIS, or submit a written request to the Registrar's Office, on or before Drop Day. This election may be reversed or reinstated at any time before the deadline. Students must resubmit their schedule in REGIS after all changes, and the pass/fail election must be approved by the student's adviser. The instructor must allow any eligible student to make this election. • Of the units offered to satisfy the requirements for the Bachelor of Science degree, no more than 90 may be in courses graded pass/fail because of the student's election (this does not include those courses taken in the first two terms during an undergraduate's first year (as a first-year student) or those designated pass/fail by the instructor, option, or curriculum committee). Procedures for Resolving Disputes over Grading At Caltech, the instructor has full responsibility for assigning grades to students enrolled in a course. On occasion, a student may not understand how a grade was determined and may seek further information. The student should first meet with the instructor or teaching assistant to discuss the grade. If after doing so the student believes the grade is unjustified or capricious, the following procedures are available. Before the end of the term following the term when the grade was issued, the student should contact the academic mediator, appointed by the provost, who will work with the student and instructor to resolve the problem. If the mediation effort is unsatisfactory to the student, they may request a formal review by an appropriate executive officer or academic officer. The executive officer will review the case and report the decision in writing to the student. If the executive officer decides that a change of grade is warranted, or if the student requests a further appeal, these shall be requested of the division chair. At the discretion of the division chair, a committee may be appointed to review the case. The committee members should interview everyone involved in the case (the student, the course instructor, the teaching assistant, and anyone else with relevant information), and make a written recommendation to the division chair. Only the division chair can authorize the registrar to enter a new grade in the student's transcript. 33 Grades and Grading 34 NOTICES AND AGREEMENTS ACADEMIC RECORDS OF VETERANS The Institute maintains a written record of a student's previous education. This is part of the student's official transcript, and included on this is a summary of any prior college-level education. A true copy of a transcript of college-level work at other institutions is maintained as part of the student's record. The amount of credit granted for prior training is indicated on the student's official transcript and, where this results in the shortening of a required training period in the case of a veteran, the Veterans Administration is notified. The Institute's official transcript for each student shows the progress that student is making at the Institute. There is a record of each course enrolled in each term with a grade recorded for the course. The total number of units earned is kept so that the record will show continued progress toward the degree sought. The final grades are recorded at the end of each term of the school year, and the accumulative permanent record has on it grades for all subjects taken at the Institute. No student is allowed to enroll repeatedly in a course and withdraw without penalty. If a student enrolls in a course, they are expected to complete the course or receive a failing grade unless they withdraw from the course prior to the deadline for dropping courses. All students must maintain a minimum load equivalent to 12 quarter hours each term; no student may drop courses that would bring them below this level of effort. At any time when the student falls below the required number of units, fails to receive satisfactory grades, or engages in unsatisfactory conduct, the record is marked to indicate this, and the student is forbidden to continue at the Institute. The grading system of the Institute is A+ (excellent) to F (failed). An At is equivalent to 4.3 and an F to 0.0. A student must maintain a grade-point average of 1.9 in any term in order to be able to enroll in a successive term at the Institute. A minimum 1.9 overall grade-point average is required for graduation. A student who drops below the required average (1.9 for a given term) is dismissed and must petition for reinstatement. A student may be reinstated by the Undergraduate Academic Standards and Honors Committee and, if so, is required to earn a 1.9 GPA during the immediately following term. The Veterans Administration is notified when a veteran is academically dismissed or is making unsatisfactory progress toward a degree. Since the Institute requires all students to carry a minimum full load that corresponds to 12 quarter hours each term, any student who finishes a term in good standing is considered to have made satisfactory progress. If a student withdraws from a course before the final date for withdrawal, no grade is given in that course. The time spent in school counts, however, and the student may be considered to have not made satisfactory progress in the event of such withdrawal. In order to withdraw from any course, a student must drop the course in REGIS or submit a written request to the Registrar's Office. The instructor should maintain the date on which the student was last in official attendance in that course. If a student reenrolls in that General Information course and successfully completes it, that fact will be noted on their official transcript. VETERANS BENEFITS AND TRANSITION ACT OF 2018 (SECTION 103) Caltech adheres to the requirements of and complies with the Veterans Benefits and Transition Act of 2018, specifically S2248 PL 115-407 Section 103. This provision was effective August 1, 2019 for any students who are considered "a covered individual" using "Chapter 33: Post 9/11 GI Bill®" benefits or any participants in "Chapter 31: Vocational Rehabilitation and Employment Program" benefits at a public, private for-profit, or not-for-profit institution regarding unpaid tuition and fees. Caltech permits any covered individual to attend or participate in courses during the period beginning on the date on which the individual provides to the educational institution a certificate of eligibility for entitlement to educational assistance under chapter 31 or 33 of this title. In accordance with S2248 PL 115-407 Section 103 Caltech will not impose any penalty, including the assessment of late fees, the denial of access to classes, libraries, or other Institute facilities, or the requirement that a covered individual borrow additional funds, on any covered individual because of the individual's inability to meet their financial obligations to the institution due to the delayed disbursement of a payment to be provided by the Secretary under chapter 31 or 33 of this title. Gl Bill® is a registered trademark of the U.S. Department of Veterans Affairs (VA). More information about education benefits offered by VA is available at the official U.S. government Web site at www.benefits.va.gov/gibill. ACCESS TO STUDENT RECORDS The Institute maintains educational records for each student that include name, address, student identification number (including Social Security number), information on parents, guardian, and spouse, general information on academic status at the Institute, previous school data, results of standardized admissions examinations, courses previously taken or being taken, credits, grades, as well as other educational records. Applicants for financial aid have an additional file holding those records. The Family Education Rights and Privacy Act (FERPA) and Caltech policy afford students certain rights as well as establish limitations with respect to student educational records. These rights and limitations are as follows: 1. Caltech permits disclosure of educational records, without consent of the student, to Institute officials with legitimate educational interests in them. An Institute official is a person employed by the Institute in an administrative, supervisory, academic or research, or support-staff position (including security personnel and health and diversity center staff), a person or company with whom the Institute has contracted (such as an attorney, auditor, consultants, contractors, or collection agent), a person serving on the Board of Trustees, or a 35 Notices and Agreements 36 student serving on an official committee, such as a disciplinary or grievance committee, or assisting another Institute official in performing their tasks. An Institute official has a legitimate educational interest if they need to review an educational record in order to fulfill their professional responsibility. They are available to the registrar, provost, president, general counsel, vice president for development and institute relations, vice president for student affairs, dean of graduate studies, dean of undergraduate students, director of financial aid, and faculty of the Institute and their respective staffs for the normal academic and business purposes of the Institute. Records involving financial aid are maintained by the director of financial aid, and are available to the director and staff, to the dean of graduate studies and staff, to the Faculty Committee on Scholarships and Financial Aid, and to the Faculty Committee on Graduate Study, for the purpose of granting and administering the Institute's financial aid program. Except as authorized by federal or state law or regulation, none of these education records nor any personally-identifiable information contained therein, other than directory information (see below), may be made available to anyone else, other than the student, without the consent of the student. Where the student consents to disclosure of personally-identifiable information from the student's education records and Caltech chooses to disclose such information, if the student so requests, the Institute will provide the student with a copy of the records disclosed. The Institute will maintain a record of each request for access to and each disclosure of personally-identifiable information from the education records of a student, as required by applicable federal law or regulation. 2. Students are allowed access to their educational records as follows: A student may inspect and review their academic transcript during normal working hours. To inspect and review other records, the student must provide a written request to the registrar or to the director of financial aid or to the dean of graduate studies or to the dean of undergraduate students, or their designees, as appropriate. A mutually-convenient time will be arranged within 45 days after receipt of the request for the student to inspect and review the records in their file. At that time the student may examine all educational records in the file with the exception of those specifically exempted by Part 99 of Title 34 of the Code of Federal Regulations. If circumstances effectively prevent the student from exercising their right to review their education records, the Institute will make other arrangements. If a student believes the educational records relating to the student contain information that is inaccurate, misleading, or in violation of the student's rights of privacy, the student may ask the Institute to amend the record. The Institute will decide whether to amend the records as requested within a reasonable time after receiving the request. If the registrar, or the director of financial aid, or the dean of graduate studies, or the dean of undergraduate students, or their designees, decide not to amend the record as requested, the student will be informed of the decision and of their right to a hearing. The student will have, on request, an opportunity for a hearing to challenge the content of the records on the grounds that the information contained in the General Information records is inaccurate, misleading or in violation of the privacy rights of the student. To request a hearing, the student must submit a written request to the vice president for student affairs or their designee. The vice president for student affairs or their designee will schedule such a hearing within a reasonable time after receipt of the request and will notify the student at a time reasonably in advance of the hearing of its date, time, and place. The student will be afforded a full and fair opportunity to present evidence relevant to the issues raised and may be assisted or represented by individuals of their choice at their own expense, including an attorney. The decision of the vice president or designee will be in writing, will be rendered within a reasonable time after the conclusion of the hearing, and will be final. This decision will be based solely upon the evidence presented at the hearing and will include a summary of the evidence and of the reasons for the decision. If, as a result of the hearing, the Institute decides that the information is inaccurate, misleading, or otherwise in violation of the privacy rights of the student, the Institute will amend the record accordingly, and inform the student of the amendment in writing. However, if, as a result of the hearing, the Institute decides that the information is not inaccurate, misleading, or otherwise in violation of the privacy rights of a student, it will inform the student of the right to place in the educational records a statement commenting on the information in the records and/or setting forth any reasons for disagreeing with the decision of the Institute. If the Institute places a statement in the education records of the student, the Institute will maintain the statement with the contested part of the record for as long as the record is maintained and will disclose the statement whenever it discloses the portion of the record to which the statement relates 3. The Institute considers the following to be directory information: a student's name, UID, addresses (permanent, campus and local/off-campus, and email), associated telephone listings, ID photograph, date and place of birth, major field of study, year in school, current enrollment status, expected date of graduation, name of academic adviser, participation in officially recognized activities and sports, weight and height if a member of an athletic team, dates of attendance, degrees and awards received, thesis title, hometown, and most recently attended educational agency or institution. Directory information may be made available to requestors at the Institute's discretion. Any student may, however, have part or all of this information withheld by notifying the registrar in writing. That information will then be withheld for the balance of that academic year. If the information is to be withheld in subsequent years, new requests must be filed. 4. A student will not be required to waive any rights regarding access to educational records. However, a student may voluntarily waive in writing right of access to confidential statements made by third parties respecting admission to educational agencies or institutions, applications for employment, or the receipt of an honor or honorary recognition. In case of waiver, the confidential statements will be used solely for the purposes for which they were specifically intended, and the student will, upon request, be notified of the names 37 Notices and Agreements 38 of all persons making such confidential statements. If a student should desire to waive right of access, may contact the registrar for more information. 5. The Institute reserves the right to destroy from time to time any and all educational records that it maintains on a student, except to the extent that the law requires their maintenance for a longer period of time. However, where access to records has been requested, no destruction of those records will be allowed to take place until such access has been granted or denied. 6. Students who believe their rights under FERPA may have been violated may file a complaint with the Family Policy Compliance Office, U.S. Department of Education, 400 Maryland Avenue SW, Washington D.C. 20202-4605. Transcripts of Records A student, or former student, may request that official transcripts of their records be forwarded to designated institutions or individuals. Requests should be filed at the Registrar's Office at least five days before the date on which the transcripts are to be mailed. PARENT, GUARDIAN, AND EMERGENCY CONTACT NOTIFICATION POLICY Caltech understands and supports a student's right to confidentiality regarding educational records1 as well as matters related to a student's experience at the Institute. Most communications from Caltech regarding academics, health and safety, advising, enrollment, and policies are directed only to students. However, the Institute does encourage students to share important information with their parents) or guardian. Subject to the allowable exceptions under FERPA, there may be circumstances under which a Caltech administrator makes the determination that notification to parents) or a guardian is indicated, and notification may be made without a student's consent. In most cases, when a Caltech administrator determines that involving parents) or guardian is necessary, the student will be given an opportunity to make contact in advance of the administrator's communication. Administrators will consider any relevant information which may indicate that notification to parents) or guardian may not be appropriate based on individual circumstances. The Institute expects all students to designate an emergency contact who is a parent or guardian or other family member who may be notified in order to address a health or safety emergency, and who is in a position to make decisions on the student's behalf in the case of a medical emergency. An alternate emergency contact also may be identified for other purposes. Situations that may warrant the involvement of a student's, parents), guardian, or emergency contact may include, but are not limited to: General Information 1. Concerns about a student under the age of 18. Caltech administrators will initiate communication with the parents) or guardian of a minor student in the cases described below, as well as any other concerns about a minor student that may benefit from collaboration with the student's support system. 2. Change in enrollment or status of an undergraduate student. A change in the enrollment status of an undergraduate student may occur as a result of disciplinary action, unsatisfactory academic progress, or other factors. If an undergraduate student is separated from the Institute, the parents) or guardian will be notified by mail at the permanent address on file. 3. Medical emergencies. State law prohibits health care professionals from disclosing medical information to the parents or guardian of a student without the student's explicit consent. In the event a student is incapacitated, unable to communicate, or otherwise cannot make decisions on their own behalf, the Institute will first cooperate with medical providers and then notify the emergency contact, parents) or guardian on file as soon as possible. 4. Unexplained absence from campus. Caltech has established a policy to assist in locating Caltech students living in Caltech campus housing when Caltech has determined a student to be missing. The key components of this policy are as follows: • Designation of Confidential Contact. Students have the option of identifying an individual to be contacted by Caltech within 24 hours after the time the student has been determined to be missing (missing person contact). This information will be accessible only to authorized campus officials and may not be disclosed except to law enforcement personnel in a missing person's investigation. If a student chooses not to provide a confidential contact and is deemed to be missing, Caltech will notify the student's emergency contact or parent. • Reporting and Investigation. Any individual who believes a student living in on campus housing may be missing should immediately contact Caltech Campus Security. Once Caltech receives a missing student report, Security will notify the Vice President for Student Affairs, the Deans, the AVP for Student Affairs and Residential Experience and the Director of Housing. Upon notification that any student may be missing, Caltech will initiate an investigation. If a student is determined to have been missing for twenty-four (24) hours and has not returned to campus, Caltech will notify the appropriate law enforcement agency and initiate other notifications as provided below. • Notification Procedures. A student's missing person contact will be notified within 24 hours of a determination by Caltech that the student is missing. If no missing person contact has been 39 Notices and Agreements 40 designated, the student's emergency contact will be notified. If the student is under 18 years of age and not an emancipated individual, Caltech is also required to notify a custodial parent or guardian within 24 hours of the determination that the student is missing. 5. Significant disruption to the campus community. The emergency contact, parents) or guardian of a student may be notified if the student is behaving in a way that is substantially disruptive to the campus community, there is reason to believe the student is at risk of harming themselves or others, or is placed under arrest or charged with a crime related to conduct on campus. 6. Repeated or flagrant violations of the Substance Abuse Policy. Caltech administrators may contact parents) or guardian if a student under the age of 21 is found responsible for serious or repeated violations of Institute policy related to the possession, use or distribution of alcohol or drugs. Consideration in these situations will be given to the following conditions: the violation involved harm or threat of harm to self, others or property; the violation involved an arrest in which the student was taken into custody; the violation resulted in or could result in the student being suspended and/or removed from an Institute residence; the student has shown a pattern of violations; the student required urgent medical intervention as a result of consumption of alcohol and/or drugs. 7. Student death. In the event of a student death, Caltech administrators will cooperate with law enforcement, the coroner, medical personnel, and any other relevant officials who will provide official notification to the deceased student's next of kin. There may be additional, unforeseen circumstances when we believe it is in the best interest of the student to notify a parent or guardian. We reserve the right to act in such cases on our own best judgment, framed within the approach to emergency contact and parental/guardian notification stated above. 'The Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232g; 34 CFR Part 99) ACCREDITATIONS AND AUTHORIZATIONS The California Institute of Technology is accredited by the WASC Senior College and University Commission (WSCUC), 985 Atlantic Ave., Ste. 100, Alameda, CA 94501; (510) 748-9001. In addition, the Institute is authorized by the California State Department of Education, Office of Private Postsecondary Education, to operate as a private postsecondary educational institution and, by the same agency, to train veterans in the programs of the Veterans Administration. The Engineering Accreditation Commission of ABET, Inc. (111 Market Place, Suite 1050, Baltimore, MD 21202-4012; 410-347-7700), has accredited Caltech's B.S. program in mechanical engineering. Further, the Committee on Professional Training of the American General Information Chemical Society has approved Caltech's B.S. program in chemistry. The documents describing these accreditations and authorizations are on file and may be inspected in the Registrar's Office and the Provost's Office; the office of the Division of Engineering and Applied Science also has the documentation for ABET. STUDENT PROBLEM RESOLUTION PROCESS Caltech provides a variety of routes, most of them informal, by which students may bring complaints, which do not fall within the jurisdiction of other Policies or the Honor System, for consideration and resolution. For example, in academic matters, students may begin with faculty-student conversations that may extend to the deans, the option representatives, the division chairs, the registrar, or to various committees having faculty and student members. Non-academic matters can be dealt with informally by student leaders, resident associates, residential life coordinators, deans, and other student affairs offices. The Graduate Student Council (GSC) and the Associated Students of the California Institute of Technology (ASCIT) may become involved in some complaints, and sometimes ad hoc groups are formed to make recommendations. The Problem-Resolution Process (Process) is intended to deal with complaints by currently enrolled students for which reasonable efforts by the available informal routes have not led to an acceptable resolution. The first step in this Process is for the student to consult with the appropriate deans. One of the deans will then determine if the issue falls under this Process and, if appropriate, may appoint a facilitator to help resolve the issue. If the student's issue involves a decision or action of a dean, the vice president for student affairs or designee may appoint a facilitator to help resolve the issue. A facilitator will assist the student in trying to work out the problem. If the student is not satisfied with the results, the student may file a written notice of appeal to the vice president for student affairs or their designee. The decision of the vice president or designee is final. If a student has a complaint about Caltech's compliance with academic program quality and accrediting standards that they believe warrants further attention after exhausting the steps outlined above, they may contact the WASC Senior College and University Commission (WSCUC) at www.wscuc.org/comments. WASC is the academic accrediting body for Caltech. An individual may contact the Bureau for Private Postsecondary Education (BPPE) for review of a complaint. BPPE may be contacted at 2535 Capitol Oaks Drive, Suite 400, Sacramento, CA 95833, website: www.bppe.ca.gov; telephone: (916) 431-6959; fax: (916) 263-1897. Prospective students may contact WASC or the BPPE with complaints as well. 41 Notices and Agreements 42 STUDENT PATENT AND COMPUTER SOFTWARE AGREEMENT The California Institute of Technology (Caltech) has a responsibility to see that inventions and copyrightable materials (including software) developed in connection with Caltech be used for the public benefit, and be consistent with Caltech's contractual obligations.

This policy, in conjunction with other applicable Caltech policies, sets forth the acceptable use of all electronic information resources owned or managed by Caltech (including those operated by third parties for Caltech, such as accounts issued by third-party cloud services for Caltech) (collectively, "Caltech IT resources") and describes the rights and responsibilities of Caltech and faculty, staff, students, and other members of or visitors to the Caltech community with respect to the use of these resources. Caltech IT resources are intended to be used to carry out the legitimate business of Caltech, although some incidental personal use is permitted. Faculty, staff, students, and other members of or visitors to the Caltech community ("users") who use Caltech's electronic information resources should be guided by the Caltech Code of Conduct. Passwords and other authentication mechanisms or devices issued to users are for their use only and are not to be shared with others. Users assume responsibility for the appropriate use of Caltech IT resources and agree to comply with all relevant Caltech policies and all applicable local, state, and federal laws. Examples of inappropriate or unauthorized use of Caltech IT resources include: • sending a communication or using electronic information resources, including websites that illegally discriminate against, harass, defame, or threaten individuals or organizations; • engaging in illegal conduct or conduct that violates Caltech policy; • destruction of, damage to, or malicious tampering with equipment, software, or data belonging to others; • disruption, interception, or unauthorized monitoring of electronic communications; • interference with use of Caltech systems; • violations of computer security systems; • unauthorized use of accounts, access codes, or identification numbers; • use that intentionally impedes the legitimate computing activities of others; • use for commercial purposes; • use for cryptocurrency mining or any other personal profit-generating activities; • use for political or lobbying activity that jeopardizes Caltech's tax-exempt status and violates Caltech policy; General Information • violation of copyrights, software license agreements, patent protections and authorizations, or protections on proprietary or confidential information; • violation of copyright laws by downloading and sharing copyrighted files; • violations of privacy; • academic dishonesty; • sending social media chain mail, spam, or other junk messages; • fraudulent activity using Caltech IT resources; • downloading, viewing, and/or sharing of materials in violation of Caltech's policies regarding Unlawful Harassment and Sex- and Gender-Based Misconduct; • unauthorized intrusion into computer systems to alter or destroy data or computer applications (e.g., hacking or cracking); • unauthorized security testing or scanning of Caltech IT resources or of another entity; • sending communications that are threatening or that may constitute stalking under Caltech's policies regarding Violence Prevention and Sex- and Gender-Based Misconduct policies; or • sending communications that attempt to hide the identity of the sender or represent the sender as someone else. Caltech will apply this policy consistent with applicable requirements under the laws and regulations governing Caltech's operations. This policy will not be construed or applied in a manner that improperly interferes with employees' rights under the National Labor Relations Act. Caltech IT resources are Caltech property or licensed by Caltech for Caltech's use. Users of Caltech IT resources should not have an expectation of privacy with respect to their use of these resources or any of the data, files, or other records generated by, stored, or maintained on them. For cybersecurity and other lawful purposes, Caltech may collect, store, and analyze information on both of the following: (1) any and all use of Caltech's electronic information resources and (2) any data or communications transmitted to or from, received or printed from, or created, stored, accessed, or recorded on Caltech's electronic information resources. This is true regardless of the labeling of the data, the use of encryption, the deletion of the data or communications, or any other factor. Password capabilities and other authentication measures are provided to users in order to safeguard electronic messages, data, files, and other records (including computer files and records, electronic mail, and voicemail) from unauthorized use. These safeguards are not intended to provide confidentiality from Caltech monitoring with respect to personal messages or files stored on electronic information resources owned and managed by Caltech. While Caltech does not routinely examine the content of electronic mail messages or otherwise monitor individual usage, it does routinely monitor the normal operation of computing and networking resources, 47 Institute Policies 48 including network activity patterns, system logs, general and individual usage patterns, and other indicia necessary to ensure the integrity and stability of its electronic information resources. Caltech will investigate suspected abuse, misuse, or compromise of its resources, systems, and services. Any user found to have violated this policy may be subject to disciplinary action, up to and including loss of administrative rights or network/system access and termination of employment or admission to the Caltech community. Caltech retains the right to inspect, review, or retain the content of electronic messages or other data, files, or records generated, stored, or maintained on Caltech IT resources at any time without prior notification. Any such action will be taken for reasons Caltech, within its discretion, deems to be legitimate. These legitimate reasons may include, but are not limited to, responding to lawful subpoenas or court orders; investigating misconduct (including research misconduct); determining compliance with Caltech policies and the law; and locating electronic messages, data, files, or other records related to these purposes. Users must therefore understand that any electronic messages, data, files, and other records generated by, stored, or maintained on Caltech IT resources may be electronically accessed, reconstructed, or retrieved by Caltech even after they have been deleted. Caltech personnel who wish to access the content of electronic mail, data, files, or other records generated, stored, or maintained by any user must request authorization as follows: (1) from the provost for any situations that require access to electronic material associated with faculty and other academic personnel; (2) from the vice president for administration and chief financial officer for staff and postdoctoral scholars at campus or the JPL director for human resources for employees and postdoctoral scholars at JPL; (3) from the vice president for student affairs for students; or (4) from the general counsel for the purposes of complying with legal processes and requirements or to preserve user electronic information for possible subsequent access in accordance with this policy. In all cases, the Office of the General Counsel should be consulted prior to deciding on whether to grant access. In the case of a time-critical matter, if the authorizing official is unavailable for a timely response, the general counsel may authorize access. Users of Caltech IT resources are advised that some authorizations already have been granted. For example, the Caltech information security team has certain authority to monitor Caltech IT resources for cybersecurity purposes. In conclusion, the use of Caltech electronic information resources is a privilege, not a right, and Caltech may revoke this privilege or decline to extend this privilege at any time. Suspected illegal acts involving Caltech electronic information resources may be reported to governmental authorities and may result in prosecution by those authorities. Any questions concerning the appropriate use of any of Caltech's electronic information resources or relevant Caltech policies should be directed to the provost, the general counsel, the chief information officer, the associate vice president for General Information human resources, the JPL director for human resources, the dean of undergraduate students, or the dean of graduate studies. Members of the Caltech community suspecting an IT security incident should report the incident via email (security@caltech.edu) or at JPL, by calling the JPL Helpdesk (4-HELP) or via email (abuse@jpl.nasa.gov).

We investigate the most challenging, fundamental problems in science and technology in a singularly collegial, interdisciplinary atmosphere, while educating outstanding students to become creative members of society. Export control laws and regulations as referred to in this Policy include a number of federal laws and regulations that impact an export or import transaction such as those of the Departments of State, Commerce, Treasury, Defense, Energy and U.S. Customs. These laws have existed for many years, however, the events of September 11, 2001, and subsequent events around the world have pushed national security concerns to the forefront. The U.S. government has responded to global security concerns by tightening the export control regulations that govern the transfer of U.S. strategic technology for national security and foreign policy reasons and in furtherance of economic objectives. The export control laws are intended to control the transfer of sensitive information or goods to individuals, entities or countries of concern. The laws impose restrictions dependent on the type of information or goods and the identity of the foreign persons and entities. The regulations contain a fundamental research exclusion and specific university exemptions that allow most of the research activities being performed at U.S. universities to be carried out without the need of export licenses or other restrictions, subject to certain conditions. The fundamental research exclusion, as defined in the U.S. export regulations, applies to basic and applied research in science and engineering performed by universities, so long as that research is carried out openly and without restrictions on publication or access to or dissemination of the research results. Caltech is an institution of 49 Institute Policies 50 higher learning conducting fundamental research in science and engineering. While the fundamental research exclusion applies to much of the research carried out at Caltech, we are not fully relieved of our responsibility to comply with the export control regulations. The National Policy on Transfer of Scientific, Technical and Engineering Information, i.e., Presidential National Security Decision Directive 189 (NSDD 189) recognizes the important contributions that U.S. universities make in science and engineering that allow our nation to remain innovative and competitive. This National Policy provides the framework for the fundamental research exclusion. The fundamental research exclusion applies only to research conducted in the United States. This exclusion allows most of the activities conducted at Caltech to be performed without the need for an export license. However, there are certain activities and information that are not covered by the fundamental research exclusion and remain subject to the export control laws and regulations. Examples of activities not covered by the fundamental research exclusion are: 1. Receipt by Caltech of third-party export controlled or other restricted information (e.g., information with restrictive marking language) which requires that appropriate measures be taken to ensure that the information is properly safeguarded from unauthorized transfers to foreign persons; 2. Under certain conditions, the disclosure of specific information and the provision of specific types of services to foreign persons (non-U.S. citizens, non-legal permanent residents, or non-U.S. legal entities) inside the United States ("deemed exports"), e.g. proprietary data, results of research where we have accepted restrictions on dissemination or participation of foreign nationals; 3. Travel abroad: Engaging in activities subject to the export regulations with persons and entities abroad such as traveling with export controlled information on electronic devices; release or disclosures of restricted US technology to foreign persons; travel to sanctioned or embargoed countries; 4. The export of controlled items and information outside the United States including: controlled hardware, software and technology (e.g., physical and non-tangible exports; emails, backing up controlled information outside the US); and 5. Financial transactions or other dealings involving prohibited parties or sanctioned countries. The export control laws and regulations may apply to research activities whether or not they are funded by grants or contracts. The export control laws are administered by the U.S. Department of Commerce through its Export Administration Regulations (EAR - dual-use items), the U.S. Department of State through its International Traffic in Arms Regulations (ITAR - space and military items), and the U.S. Department of Treasury through its Office of Foreign Assets Control (OFAC - economic and trade sanctions). These laws control the conditions under which certain information, technologies, and General Information commodities can be transmitted overseas to anyone, including U.S. citizens, or to a foreign person on U.S. soil. Caltech is committed to comply fully with these federal laws and regulations. Caltech takes its commitment to openness in research very seriously. Caltech's policy, as set forth in the Faculty Handbook, does not allow acceptance of any government contract or grant that impinges on Caltech's ability to freely publish and otherwise disseminate the results of its research. The transfer of export controlled information or items requires added levels of security, safeguarding responsibilities and, in some instances, government authorization. For these reasons, research activities in which students will be provided with export-controlled technology (including technical data, software or items) with ITAR or high EAR (e.g., 500- and 600-series Export Control Classification Number*) controls or licensing requirements, must be formally approved by the Office of the Provost. Caltech has established an Export Compliance Office and has appointed a Director for Export Compliance who also functions as Caltech's Empowered Official. The Empowered Official is the person who has legal authority to sign export control license applications and other requests for export approval on behalf of Caltech, and is the person responsible for developing and implementing export compliance programs, campus procedures, awareness programs for faculty and training programs for staff. Caltech expects all faculty and staff to comply fully with all applicable export control laws and regulations. (The Jet Propulsion Laboratory, a federally funded research and development center, has a separate Export Compliance Policy.) Noncompliance may result in violations that can subject both the individual and Caltech to civil sanctions and criminal penalties. It is the responsibility of Caltech faculty and staff to ensure Caltech's compliance with this policy. The Director for Export Compliance has been designated as the primary contact for export control issues. For more information or for questions, please contact: Adilia F. Koch, Director for Export Compliance, (626) 395-4469 or the Export Compliance Office staff at (626) 395-2641 or export@caltech.edu. * Export Control Classification Numbers (ECCNs) are described on the Department of Commerce's website here: www.bis.doc.gov/index.php /licensing/commerce-control-list-classification/export-control-classific ation-number-eccn. CONFLICTS OF INTEREST POLICY 1.0 Policy The mission of Caltech is to expand human knowledge and benefit society through research integrated with education. In pursuit of this mission, Caltech adheres to its Code of Conduct and strives for the highest level of integrity and public confidence. Caltech's integrity rests on the personal integrity of each of us who is called upon to act 51 Institute Policies 52 on behalf of Caltech. Caltech, including JPL, is committed to ensuring that decisions made on its behalf reflect the highest ethical standards and that its research and instruction remain a rigorous and open inquiry, unencumbered by conflicts of interest, real or perceived, that might affect the sound judgment of its trustees, officers, senior management, faculty, students, postdoctoral scholars, staff, including JPL employees, and visitors. Each of us, therefore, is responsible for identifying and resolving conflicts between personal and institutional interests. We each must act in the best interests of Caltech and refrain from taking part in any transaction where we do not believe in good faith that we can act impartially. Individual conflicts of interest may affect Caltech's trustees, officers, faculty, postdoctoral scholars, students, staff, including JPL employees, and visitors. An individual conflict of interest is a situation that may compromise an individual's professional judgment in carrying out Institute business due to an external relationship that directly or indirectly affects the interest of the individual or an immediate family member. Each situation that presents a potential for conflict of interest must be fully disclosed to Caltech and managed or eliminated before moving forward. Conflicts of interest also include conflicts of commitment, which are situations in which external activities, either paid or unpaid, interfere with an employee's primary obligation and commitment to Caltech. While everyone should take care to avoid conflicts of commitment, there are special considerations, including disclosures, that apply to those performing federally sponsored research at Caltech. Federal sponsors have an interest in ensuring that the researchers supported on their awards are not over committed. The Division Chairs and the Office of Research Compliance serve as resources to researchers who have questions concerning whether particular activities they are considering may pose a conflict of commitment. Faculty, postdocs, visiting researchers, and all employees are expected to comply with this policy and are required to complete Caltech's Financial Interest and Commitment Disclosure Form within 30 days of hire and on an annual basis, and to submit changes or additions within 30 days of a new interest, activity, or change. In academic research, the term conflict of interest refers especially to situations in which financial or other personal considerations may compromise, or may have the appearance of compromising, an investigator's professional judgment in conducting or reporting research. The bias can affect collection, analysis, and interpretation of data, hiring of staff, and procurement of materials, sharing of results, choice of protocol, and the use of statistical methods. Conflicts of interest can affect all scholarly fields. Caltech has established its conflict of interest policies and procedures that apply to all Caltech employees, including faculty, to ensure compliance with Caltech's ethical standards as well as with the laws, rules, and regulations that govern Institute activities, while fostering and sustaining an environment of openness and integrity. General Information 2.0 Individual Conflicts of Interest The broad principles in this policy encompass a variety of situations, many of which do not fall into patterns for which specific guidelines may be established. Conflicts of interest inevitably arise from time to time in everyday business life; some may appear to be inconsequential or may even be advantageous to Caltech. It is important, however, that all employees make timely disclosure of any such conflict of interest. Each employee should apply their sense of integrity and common sense to disclose any circumstances that are, may become, or may give the appearance of a possible conflict of interest. Supplementing this broad policy statement are the following rules to be observed on specific matters: 2.1 Each employee has a duty to act in the best interest of Caltech and avoid actions that would call into question the integrity of the employee or Caltech. 2.2 An employee who has directly or through family or business connections, a material interest in suppliers of goods or services, or an interest in contractors or potential contractors with Caltech, should not act on behalf of Caltech in any transaction involving that interest. No employee should participate in the selection, award, or administration of a contract with any party with whom they are negotiating regarding potential employment or any arrangement concerning potential employment. 2.3 An employee should avoid outside activity involving obligations that may conflict or appear to conflict with Institute interests, including its interest in the employee's full- or part-time services (i.e. a conflict of commitment). Activities to disclose include, but are not limited to, paid or unpaid directorships, external academic appointments, editorial positions, service on advisory boards, consulting or similar arrangements, and other outside employment. Campus and JPL staff and postdoctoral scholars are required to obtain approval prior to engaging in outside activities. Campus and JPL staff and postdoctoral scholars must complete the Request for Outside Activity form as required in Personnel Memorandum PM 9-3. JPL Employees should submit Outside Activity Requests online and may contact the JPL Ethics office for assistance. 2.4 To avoid the appearance of a conflict of interest, an employee should provide full disclosure of any business or financial enterprise or activity in which they are involved that might influence, or might appear to influence, their official decisions or actions on Caltech matters. 2.5 An employee should refrain from personal activities that include, but are not limited to, the purchase or sale of securities, real property, or other goods or services in which they could use or might appear to have the opportunity to use, for personal gain, confidential information or special knowledge gained as a result of their relationship with Caltech. 2.6 An employee should refrain from unauthorized disclosure of nonpublic information concerning Caltech. Additionally, an employee should not use nonpublic information accessed through the performance of a government contract for personal gain. 53 Institute Policies 54 2.7 No employee should make unauthorized use of Caltech resources for their personal benefit or for the benefit of any other person. Incidental personal use of resources is authorized by Caltech. See Acceptable Use of Electronic Information Resources Policy and JPL Rules for requirements on incidental use and activities at JPL. 2.8 It is sound practice to discourage gifts and favors from people with whom Caltech has a business relationship. Personal gifts of more than nominal value should be tactfully declined or returned to avoid any appearance or suggestion of improper influence. Any employee involved in awarding or administering contracts using federal or other government funds should keep in mind that state and federal law contain prohibitions against soliciting or accepting gratuities, favors, or anything of monetary value from contractors or potential contractors. 2.9 Any employee doing business on behalf of Caltech with specific vendors should refrain from going on leisure trips with representatives of those vendors. Such trips are not appropriate, even when a staff employee pays a fee to the vendor to participate in such trips. 2.10 No employee should act in any Institute matter involving a member of their immediate family including, but not limited to, matters affecting family members' employment or evaluation or advancement at Caltech. Immediate family includes an employee's spouse or domestic partner and children. The employment of relatives as that term is defined in Personnel Memorandum (PM 9), is subject to the conditions and restrictions described in PM 9, including the requirement to complete the Nepotism Evaluation process whenever a relative of an employee is considered for employment in the same organization as the employee. Any employee who believes that their conduct or activities may or may appear to conflict with these guidelines or activities or otherwise create a conflict of interest, should make an appropriate disclosure. You may also report possible conflicts of interest by calling the Campus Hotline at (626) 395-8787 or submitting a hotline form. JPL employees should consult Laboratory requirements and seek guidance and/or report possible conflicts of interest by contacting the JPL Ethics Office at (818) 354-6338. 3.0 Additional Faculty Responsibilities It is acknowledged that, in their wider roles as academicians and professionals, the faculty may be subject to conflicts of interest that are not necessarily financial and that are not within the scope of a policy that is designed to address conflicts of interest in the employer-employee setting. For example, this policy is not designed to address conflicts that may be encountered in service to a professional society. Other activities not covered by this policy are best handled within the ethical guidelines established by the Faculty Handbook. Faculty members must be aware of potential conflicts to ensure an open and productive environment for research and teaching. Conflicts of interest may arise when faculty members have the opportunity to influence Caltech's business decisions or when outside relationships may or may appear to compromise the integrity of decisions made as teachers and researchers. A faculty member's General Information general commitment to Caltech requires that members perform their responsibilities to Caltech and appropriately use their own judgment in deciding whether to engage in a variety of extramural activities, within the confines set forth in the Faculty Handbook. As a result, Caltech relies on its faculty to be alert to the possible effect of outside activities on the integrity of their decisions and on their ability to fulfill their obligations to Caltech and to federal and private research sponsors. Accordingly, in addition to the conflict rules set forth above, the following guidance is provided for faculty: 3.1 Disclosure is imperative if the faculty member directs students in a research area and, as a result, the faculty member intends to realize financial gain. An example is a research area within the ambit of a business in which the faculty member has a significant ownership interest or is employed by or acts as a consultant for the business. Any involvement of undergraduates, graduate students, or postdoctoral scholars in the outside professional activities of the faculty member directing the student's research must be specifically approved in advance by the division chair. The student or postdoctoral scholar must also sign the written disclosure to signify understanding of the 3.2 Disclosure is mandatory if the faculty member has a significant interest in a business under circumstances that link the fortunes of the business to the faculty member's research. 3.3 Disclosure is mandatory if the faculty member is to receive sponsored support for research from a business for which the faculty member is a consultant, or in which the faculty member has a significant financial interest. 4.0 Conflict of Interest Requirements Imposed by Federal Sponsors Federal sponsors, including the Defense Advanced Research Projects Agency (DARPA), Department of Energy (DOE), National Science Foundation (NSF) and Public Health Service (PHS), have issued specific rules regarding the disclosure of significant financial interests and the management of financial conflicts of interest as a condition for submitting proposals and accepting awards of financial support from these agencies. Members of the Caltech community proposing or working on any activity funded by a federal sponsor, including DARPA, DOE, NSF or PHS (including the National Institutes of Health) are required to comply with Caltech's Policy and Procedures for Managing Conflict of Interest Requirements Imposed by Federal Sponsors, and other sponsor disclosure requirements. 5.0 Institutional Conflicts of Interest Policy Institutional conflicts of interest differ from individual conflicts of interest. An institutional conflict of interest is a situation in which the research, teaching, outreach, or other activities of Caltech may be compromised because of an external financial or business relationship held by Caltech that may bring financial gain to Caltech. 55 Institute Policies 56 5.1 Identifying Institutional Conflicts of Interest Caltech has many legitimate interests that may at times conflict. Management of institutional conflicts of interest is by its very nature more complex than that of individual conflicts of interest. External relationships to sponsors and supporters of the institution, the local community's acceptance of economic development activities, the institution's obligations as a charitable organization receiving preferential tax treatment, and the institution's perception of its teaching, research, and academic missions all impact how potential conflicts of interest are managed. The examples and issues presented below do not necessarily constitute inappropriate conflicts of interest. Each situation must be judged on the facts and merits of the relationship with an eye to what reasonable individuals outside Caltech might consider to be appropriate. Any activity, financial and/or operational, that may bring into question Caltech's reputation, integrity, and objectivity should be considered for possible conflicts of interest. The following are examples of potential situations that may give rise to institutional conflicts of interest: 5.1.1 Significant gifts to Caltech from a commercial sponsor of research may raise questions about the influence of the company on Caltech's research programs and how they are managed. Similar concerns arise when individual companies sponsor research or provide significant consulting income to a significant number of faculty members within a single academic division. Gifts or promise of gifts, in exchange for favorable terms on a technology license or a first look at intellectual property may also pose a problem. 5.1.2 The acquisition of goods and services for Caltech represents a large portion of Caltech's expenditures. Purchasing goods and services from companies that sponsor research at Caltech, or who are licensees of Institute technology, may raise issues similar to those raised by large gifts from commercial sponsors. 5.1.3 A potential institutional conflict of interest exists simply by Caltech having a license agreement with, or an equity position in, a company sponsoring a faculty member's research. In these situations, there may be, or may appear to be, a bias to accept terms and conditions that would facilitate the company's success. 5.2 Reporting Institutional Conflicts of Interest If you identify a situation that may pose an institutional conflict of interest, you should report the situation to either the vice president for administration and chief financial officer or to the provost on campus or to the associate director for business at JPL. You may also make a report by calling the Campus Hotline at (626) 395-8787 or submitting a hotline form, or calling the JPL Ethics Office at (818) 354-6338. General Information DISABILITY AND REASONABLE ACCOMMODATION 1.0 Policy It is Caltech's policy to comply fully with the Americans with Disabilities Act (ADA), the Rehabilitation Act, and other applicable federal and state laws to ensure equal opportunity for otherwise qualified individuals with disabilities, including disabled veterans. Caltech does not discriminate based on physical or mental disabilities and is committed to ensuring that there is no unlawful discrimination or harassment in any of its academic or employment programs, services, activities, or in any terms and conditions of employment. As required by law, Caltech will make reasonable accommodations to otherwise qualified individuals with known disabilities, including students, faculty, postdoctoral scholars, staff, volunteers, interns, and job applicants, to ensure equal employment opportunities and equal access to Caltech educational programs, services, activities, and facilities unless doing so would constitute an undue hardship or a fundamental alteration. Caltech also will provide reasonable accommodations to employees with pregnancy-related conditions consistent with federal and state law. Caltech also, as appropriate, will conduct a fair, timely, and thorough investigation into complaints within the scope of this policy to determine what occurred and take reasonable steps to remedy the effects of any discrimination and prevent recurrence of the behavior. Caltech provides all parties with appropriate due process and reaches reasonable conclusions based on the evidence collected. Caltech takes appropriate action, including disciplinary measures, when warranted. 2.0 ADA Coordinators The following individuals have been designated to coordinate Caltech's efforts to comply with and carry out its responsibilities under applicable disability laws and Caltech policy (ADA coordinators). Individuals who believe they have been discriminated against based on their disability or who wish to request an accommodation should contact the appropriate Caltech ADA coordinator.

In evaluating requests for accommodations, Caltech will engage in a timely and good-faith interactive process with the requesting individual to determine what, if any, accommodations should be provided. Caltech has the right to request documentation supporting an accommodation request, including documentation of the disability when the disability or the need for accommodation is not obvious. 4.0 Right to File a Grievance An individual who believes they have been the subject of disability discrimination may file a grievance. In addition, after engaging in the interactive process and after Caltech has determined whether a reasonable accommodation is available, an individual requesting an accommodation who disagrees with the decision may file a grievance under the Disability and Reasonable Accommodation Grievance Procedures. Grievance procedures may be obtained from the appropriate ADA coordinator or at the links provided at the end of this policy. 5.0 Right to File Complaint with Outside Agency Employees and applicants may also file a complaint with the U.S. Equal Employment Opportunity Commission, the California Department of Fair Employment and Housing, and the U.S. Department of Labor, Office of Federal Contract Compliance Programs, or the U.S. Department of Education, Office for Civil Rights. Students may file complaints with the U.S. Department of Education Office for Civil Rights at (415) 486-5555 (or OCR.SanFrancisco@ed.gov) or (800) 421-3481 (or OCR@ed.gov).

Confidentiality will be maintained to the extent possible. Any employee in a supervisory role, including faculty, must promptly report all alleged harassment, discrimination, sex- and gender-based misconduct, and retaliation, regardless of its alleged severity or frequency, to the Equity and Title IX Office at campus or Human Resources at JPL, which will provide guidance and advice. In addition, other employees qualifying as responsible employees under the Sex- and Gender-Based Misconduct Policy, Reporting Concerns and Complaints, Il, 6.2, must promptly report any instance of prohibited conduct, as defined in Prohibited Conduct, Ill, Sections 15.0 and 16.0, to the Equity and Title IX Office or the Deputy Title IX coordinator for JPL, as appropriate. 4.0 Anonymous Reporting Caltech provides the following resources for anonymous reporting: • Campus Hotline: (626) 395-8787 or (888) 395-8787 • Equity and Title IX Office Online Report a Concern Form (complete anonymously): Online Report Form | Equity and Title IX Office (caltech.edu) • JPL Ethics Hotline: (818) 354-9999 • JPL Protective Services Division's Workplace Violence Hotline: (818) 393-2851 • For either Campus or JPL by submitting a compliance Hotline Contact Form A report is considered anonymous if the reporting party does not share their name or contact information. If a reporting party chooses to provide their name or contact information they will receive information about support resources, reporting options, and notification of ar investigation, if an investigation is pursuec 65 Institute Policies 66 5.0 Reporting to Outside Agencies In addition, employees who believe they have been subject to unlawful harassment or discrimination have the right to file a complaint with the federal Equal Employment Opportunity Commission or the California Department of Fair Employment and Housing, which have the authority to remedy violations. Employees, students, and others participating in Caltech's educational programs and activities may file complaints with the U.S. Department of Education Office for Civil Rights at (415) 486-5555 (or ocr.sanfrancisco@ed.gov) or (800) 421-3481 (or OCR@ed.gov). Complaints may also be directed to the Bureau for Private Postsecondary Education at bppe.ca.gov. 6.0 Investigation of Complaints Caltech will conduct a fair, timely, and thorough investigation into complaints within the scope of this policy to determine what occurred and take reasonable steps to remedy the effects of any discrimination and prevent recurrence of the behavior. Caltech provides all parties with appropriate due process and reaches appropriate conclusions based on the evidence collected. Caltech takes appropriate action, including disciplinary measures, up to and including termination, student expulsion, or being permanently banned from Caltech premises, when warranted. 7.0 Policy against Retaliation No one may intimidate, threaten, coerce, or discriminate against any individual for the purpose of interfering with any right or privilege secured by this policy or the related procedures, or because the individual has made a report or complaint, testified, assisted, participated, or refused to participate in any manner in any action or process under this policy or the related procedures. Intimidation, threats, coercion, or discrimination for the purpose of interfering with any right under this policy or the related procedures constitutes retaliation. The rights and privileges secured under this policy and the related procedures include but are not limited to: (i) filing or assisting in the filing of a complaint or report of a suspected violation of this policy; (ii) opposing any act or practice made unlawful by any federal, state or local laws requiring equal opportunity; (iii) participating, assisting, or otherwise cooperating in an investigation, compliance review, hearing, or any other activity related to a violation of this policy or administration of any federal, state, or local law requiring equal opportunity; and/or (iv) exercising any legal right protected by federal, state, or local law requiring equal opportunity. The following actions do not constitute retaliation: the exercise of rights protected under applicable law or Caltech's charging an individual with a policy violation for making a materially false statement in bad faith in the course of a resolution process. A determination that a respondent was or was not responsible for alleged misconduct alone is not sufficient to conclude that any party made a materially false statement in bad faith. Complaints of retaliation will be addressed under the Procedures for Complaints of Unlawful Discrimination, Harassment, and General Information Retaliation. 8.0 Informational Resources Information on equal employment opportunity and nondiscrimination, as well as copies of Caltech's Nondiscrimination and Equal Employment Opportunity, Unlawful Discrimination, Harassment and Retaliation, Sex- and Gender-Based Misconduct, and Violence Prevention policies are available from Caltech's Title IX coordinator and deputy coordinators, Human Resources, Student Affairs and deans' offices, the Center for Inclusion & Diversity, resident associates, the Staff and Faculty Consultation Center, and Employee & Organizational Development at Campus, and Employee Relations and the Human Resources Business Partners at JPL. The policies, available at the links below, are published in the Caltech Catalog and on the following Caltech websites: Caltech Human Resources, JPL Human Resources, Equity and Title IX Office, and Student Affairs. 9.0 Caltech's Commitment to Equal Opportunity and Nondiscrimination To ensure equal employment opportunity and nondiscrimination, each member of the Caltech community must understand the importance of this policy and their responsibilities to contribute to its success. The president of Caltech fully supports Caltech's equal opportunity and affirmative action policies. Related Policies and Procedures: • Unlawful Discrimination, Harassment and Retaliation • Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation • Sex- and Gender-Based Misconduct • Procedures for Complaints of Sex- and Gender-Based Misconduct under Title IX • Disability and Reasonable Accommodation SEX- AND GENDER-BASED MISCONDUCT SECTION I: INTRODUCTION 1.0 Policy All members of the Caltech community have the right to be treated, and the responsibility to treat others, with dignity and respect. These principles are fundamental to the educational and intellectual mission of Caltech. It is the policy of Caltech to provide a work and academic environment free of discrimination, harassment, sexual misconduct, and retaliation. Caltech will not tolerate such conduct and is committed to educating the community in ways to prevent its occurrence. As defined in this policy, sex- and gender-based discrimination, sexual and gender-based harassment, and sexual misconduct, including sexual assault, sexual battery (i.e., nonconsensual sexual contact), dating and domestic violence, sexual exploitation, and stalking constitute prohibited conduct and violate this policy. Such 67 Institute Policies 68 conduct generally violates Title VIl of the Civil Rights Act of 1964, as amended; Title IX of the Education Code; and/or California law. All individuals are protected against prohibited conduct (defined below in Section III) regardless of gender. For the purposes of this policy, the term "gender" is broadly defined, encompassing sex, sexual orientation, gender identity, and gender expression. Prohibited conduct can be committed by individuals of any gender and can occur between or among individuals of the same gender or different genders, strangers, or acquaintances as well as people involved in intimate or sexual relationships. Caltech also prohibits retaliation against an individual who reports, submits a complaint, or otherwise participates in good faith in any matter related to this policy. Caltech will take prompt and equitable action upon receiving a report of prohibited conduct to determine what occurred and will take steps to stop and remedy the effects of any such conduct and prevent its recurrence. Caltech provides all parties with appropriate due process and will take appropriate action, including disciplinary measures, when warranted, up to and including termination of employment or changes to student enrollment status, including expulsion. Any reference in this policy to a Caltech administrator is understood to include not only that administrator but also their designee. 2.0 Scope This policy applies to all current students, faculty, supervisory and nonsupervisory staff, postdoctoral scholars, volunteers, interns, vendors, independent contractors, persons performing services under contract with the Institute, visitors, and any other individuals who are regularly or temporarily employed, studying, living, visiting, or otherwise participating in Caltech's educational programs or activities ("covered persons"). The requirement not to discriminate in Caltech's educational programs or activities also extends to admissions and employment. Inquiries about the application to Caltech of Title IX and its implementing regulations may be referred to the Title IX Coordinator. This policy applies, when both parties are covered persons, to (a) prohibited conduct occurring on Institute-controlled property, at Institute-sponsored events, in Institute programs or activities, or Institute-owned or controlled residential facilities, regardless of location; (b) prohibited conduct occurring on property or at events controlled or sponsored by Institute-affiliated organizations including student organizations, regardless of location; (c) prohibited conduct occurring off campus, in any location or context, when the occurrence of such alleged conduct could contribute to a hostile educational environment or otherwise interfere with a student's access to education; or (d) prohibited conduct occurring outside of Caltech's educational programs or activities, whether they occurred on or off campus, if, based on the allegations, there is any reason to believe that the incident could contribute to a hostile educational environment or otherwise interfere with a student's access to education. General Information Organizations affiliated with the Institute or that use Caltech property or resources in connection with their activities also are prohibited from engaging in prohibited conduct. This policy also applies at the Jet Propulsion Laboratory (JPL). Members of the Caltech community are encouraged to promptly report prohibited conduct to Caltech or consult with a confidential resource (see Appendix: Support Resources), regardless of where the incident occurred or who committed it. Supervisory employees and other Responsible Employees are required to promptly report prohibited conduct. An individual who has experienced sexual misconduct is encouraged to immediately seek assistance from a medical provider and report the incident to local law enforcement, which the confidential Campus Sexual Violence Advocate can coordinate and facilitate. Reports to Caltech and law enforcement may be pursued simultaneously. Even if Caltech does not have jurisdiction under this policy over the person accused of prohibited conduct, or the allegations reported, Caltech will take prompt action, as warranted and appropriate, to provide for the safety and well-being of the individual reporting and the campus community, including taking reasonable steps to stop and remedy the effects of the prohibited conduct and to prevent recurrence of the behavior. 3.0 Retaliation Retaliation against any member of the Caltech community at any point in time for making a good-faith report of prohibited conduct or participating or refusing to participate in any manner in an investigation, proceeding, or hearing conducted by Caltech, or a state or federal agency is strictly prohibited. Retaliation is defined as overt or covert acts of reprisal, interference, discrimination, intimidation, or harassment against an individual or group for exercising their rights under Title IX or other federal and state laws. Threats of retaliatory action also constitute retaliation. Retaliation violates this policy and is unlawful. Retaliation does not include charging an individual with a code of conduct violation for making a materially false statement in bad faith during the course of an investigation, proceeding, or hearing related to this policy, provided, however, that a determination regarding responsibility, alone, is not sufficient to conclude that any party made a materially false statement in bad faith. The following are examples of conduct that may constitute retaliation: • A faculty or staff supervisor suspects and assigns blame for an anonymous report to the Equity and Title IX Office and gives the suspected reporter undesirable work or lab assignments, or a lesser recommendation or salary increase than the suspected reporter merits based on their actual work. A faculty or staff supervisor refuses to continue to work with a student, subordinate, or colleague who has reported a concern about them to the Equity and Title IX Office. 69 Institute Policies 70 • A student spreads false information around the House about a fellow student who has reported a concern about them or a friend to the Equity and Title IX Office. • A student gets other students to engage in "blackballing" or socially ostracizing behavior against a student who was called as a witness in a Title IX investigation where the respondent was a friend of the student organizing the blackballing. • A staff supervisor requires an employee who raised concerns with them about differential treatment between men and women on the team to track their weekly time on assignments, but no one else is required to track their time, and there is no prior employment history to support the necessity of tracking time. Caltech will take steps to prevent retaliation and will take prompt and appropriate corrective action to stop and remedy its effects if retaliation occurs. Caltech will involve senior academic, administrative, and Student Affairs leadership, as required, to prevent and remedy retaliation. Individuals who violate Caltech's policy prohibiting retaliation may be subject to disciplinary action up to and including termination of employment or expulsion from Caltech. 4.0 Preservation of Evidence of Prohibited Conduct Prohibited conduct, as defined in this policy, may also be a crime. Individuals who have experienced sexual violence are urged to seek medical treatment as soon as possible. Sexual assault forensic exams (or rape kit tests) are available free of charge at multiple local medical centers (see the Appendix: Support Resources chart at the end of this policy) and facilitate both evidence preservation and any necessary medical treatment. Evidence preservation is important in case an individual would like to file a report with law enforcement, pursue civil litigation, or obtain a protective order. If an individual chooses to receive a forensic exam, they should avoid showering, bathing, douching, eating, drinking, washing their hands, or brushing their teeth until after the medical examination. Exams should be performed within 72 hours of the incident. Individuals should save all clothing worn at the time of the assault. Each item of clothing should be placed in a separate paper bag, not a plastic bag. Individuals who have experienced sexual violence are strongly encouraged to preserve all physical and electronic evidence. Examples of physical evidence may include clothing, bedding, contraceptives, letters, and notes. Any such items relating to an incident of prohibited conduct should be preserved. Electronic evidence relating to any type of incident of prohibited conduct, such as texts, emails, photos, and social media posts, should be preserved. Once an individual reports a concern or receives notification of their respondent or witness, they are required to preserve any physical or electronic evidence they have. An intentional failure to preserve such evidence may be grounds for disciplinary action. General Information 5.0 Emergency Notifications and Timely Warnings In the event of a dangerous situation on campus that has involved an immediate threat to the health or safety of students or employees, Caltech will issue an emergency notification consistent with its emergency notification procedures. In the event that Caltech believes that there is a serious or continuing threat to the campus community, Caltech will issue a timely warning consistent with its timely warning procedures. Emergency notifications and timely warnings do not disclose the name of the victim. SECTION II: REPORTING CONCERNS AND COMPLAINTS 6.0 Reporting to Caltech Any person may report prohibited conduct, whether or not the person reporting is the person alleged to be the victim of the alleged prohibited conduct. They may make their report in person, by mail, by telephone, by electronic mail, or by any other means that results in the Title IX Coordinator receiving their verbal or written report. They may also use the Report Form on the Equity and Title IX Office website, which can be submitted anonymously by not filling in the contact information. The Report Form is also available from the Equity and Title IX Office and at equity.caltech.edu. A member of the Caltech community who wishes to report prohibited conduct should do so as soon as possible after the incident, although reports may be made at any time. Anyone who witnesses, experiences, or is otherwise aware of conduct that the individual believes to be in violation of this policy, including retaliation, is urged to contact Caltech immediately. Individuals are encouraged to report to the Title IX Coordinator or a deputy coordinator. Any employee in a supervisory role, including faculty, must promptly report all alleged sexual harassment, sex and gender-based misconduct, and retaliation, regardless of its alleged severity or frequency, to the Title IX Coordinator at campus or Deputy Title IX Coordinator for JPL, who will provide guidance and advice. In addition, other employees qualifying as Responsible Employees under 6.2 below must promptly report any instance of prohibited conduct to the Title IX Coordinator or the Deputy Title IX Coordinator for JPL, as appropriate. If a member of the Caltech community would like support and guidance in reporting prohibited conduct, they may contact the Title IX Coordinator or a deputy coordinator, one of the deans or associate deans, the director of employee and organizational development in Human Resources, or the JPL section manager of talent management or Human Resources Business Partners at JPL. They may also contact any of the EEO coordinators identified in the Nondiscrimination and Equal Employment Opportunity Policy. Caltech is committed to protecting the privacy of all individuals involved in a report of prohibited conduct. All administrators involved in responding to a report of prohibited conduct understand the importance of properly safeguarding private information. Caltech will make every effort to protect individuals' privacy interests consistent with Caltech's obligation to address reports made to Caltech. 71 Institute Policies 72 A student who participates as a complainant or witness in an investigation of sexual assault, dating violence, domestic violence, or stalking will not be subject to disciplinary sanctions for a violation of Caltech's student conduct policies at or near the time of the incident, including but not limited to the Substance Abuse policy, unless Caltech determines that the violation was egregious, including but not limited to an action that places the health or safety of any other person at risk or involves conduct that violates Caltech's policies prohibiting discrimination or other serious misconduct like plagiarism, cheating, research misconduct, or other forms of academic dishonesty. 6.1 Title IX Coordinator and Deputy Coordinators The Title IX Coordinator is responsible for coordinating Caltech's compliance with Title IX and for Caltech's overall response to prohibited conduct falling under Title IX. The Title IX Coordinator oversees the implementation and application of this policy and the related procedures to ensure the prompt and equitable resolution of complaints and the consistent treatment of the parties involved. In doing so, the Title IX Coordinator oversees all Title IX-covered and other sex-and gender-based misconduct complaints, monitors outcomes, identifies and addresses any patterns of systemic problems that arise, and assesses effects on the campus climate. The Title IX Coordinator is supported by four deputy Title IX Coordinators and a lead investigator, all of whom can answer questions regarding Caltech's Title IX-related policies and Title IX Deputy Title IX Coordinators also generally serve as co-investigators to the lead investigator under the formal investigation process set out in the Procedures for Complaints of Sexual Misconduct Under Title IX and the California Education Code.

In addition, under the Unlawful Harassment Policy, any employee in a supervisory role, including faculty, must promptly report all alleged harassment, discrimination, and retaliation, regardless of its alleged severity or frequency, to the Equity and Title IX Office at Campus or Human Resources at JPL, which will provide guidance and advice. 6.3 Anonymous Reporting Caltech provides the following resources for anonymous reporting: Campus Hotline (626) 395-8787 or (888) 395-8787 JPL Ethics Hotline (818) 354-9999 JPL Protective Services Division's Workplace Violence Hotline (818) 393-2851 For either Campus or JPL, by submitting a compliance Hotline Contact Form You may also use the Report Form on the Equity and Title IX Office website, which can be submitted anonymously by not filling in the contact information. A report is considered anonymous if the reporting party does not share their name or contact information. If a reporting party chooses to provide their name or contact information they will receive information about support resources, reporting options, and notification of an investigation, if an investigation is pursued. 6.4 Notification of Law Enforcement Individuals who have experienced sexual assault, stalking, sexual exploitation, or domestic, relationship, or dating violence are encouraged to notify local law enforcement. Caltech will provide assistance in notifying law enforcement if the individual so chooses. An individual who has experienced sexual violence also has the right to decline to notify law enforcement or Caltech. Caltech does not report sex- and gender-based misconduct to law enforcement on a complainant's behalf, unless such a report is mandated by law (e.g., sexual assault of a person under 18, de-identified reporting as required under California Education Code Section 67383). General Information If the complainant chooses to notify law enforcement, they may seek the assistance of the Equity and Title IX Office. The Equity and Title IX Office is available to facilitate the contact with law enforcement and the scheduling of a meeting, if the complainant chooses to make a report. Caltech has an obligation under California law to report incidents of sexual assault to law enforcement; however, Caltech will not report identifying information about the complainant without the complainant's consent after being notified of their right to have personally identifying information withheld. If the complainant does not consent to be identified, personally identifying information about the respondent also will not be provided. Individuals may also engage with the confidential Campus Sexual Violence Advocate (see Appendix: On-Campus Mental Health and Emotional Support Resources), who can facilitate a report to law enforcement. The Campus Sexual Violence Advocate will notify the Title IX Coordinator of a sexual assault for reporting purposes but will not provide any identifying information. Pasadena Police Department Call 911 for Emergency Response Non-Emergency Response: (626) 744-4241 207 N. Garfield Ave., Pasadena, CA 91101 7.0 Reports Involving Minors Every member of the Caltech community who knows of or reasonably suspects child abuse or neglect, including any prohibited conduc nvolving a minor, has a personal responsibility to report the suspecte child abuse or neglect to Caltech Security or the JPL Protective Services Division immediately. Caltech employees who are mandated reporters have additional, legally required reporting obligations, including reporting immediately to the LA County Office of Child Protection and/or the local police department. See Mandated Reporter Guidelines and the Violence Prevention Policy for more information. 8.0 False Reports Caltech expects its members to act with honesty, sincerity, and good faith in reporting concerns under this policy. Caltech will not tolerate intentional false reporting of information, allegations, or evidence. A good faith complaint that is not substantiated by a preponderance of the evidence after an investigation is not considered a false report. However, when a complainant or third party is found to have intentionally fabricated or knowingly misrepresented information, allegations, or evidence, or otherwise to have acted with an intent to deceive or mislead in any of their dealings relating to Caltech's administration of this policy, they may be subject to disciplinary action up to and including termination of employment or expulsion. 75 Institute Policies 76 9.0 Privacy Caltech will maintain the privacy of all individuals involved in a report of prohibited conduct to the extent practicable. All Caltech employees who are involved in the Institute's receipt of the report and the response, including the Title IX Coordinator, deputy coordinators, and investigators, receive training about respecting and safeguarding private information. Throughout the process, every effort is made to protect the privacy interests of all individuals involved in a manner consistent with the need for a thorough review and administration of the matter. Privacy generally means that information related to a report of prohibited conduct will only be shared with those individuals who have a "need to know." The determination of who has a "need to know" is within the discretion of the Title IX Coordinator. These individuals are required to treat the information and respect the privacy of all individuals involved appropriately. No meetings or conversations that take place under this policy, the Procedures for Complaints of Sexual Misconduct, or the Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation may be audio- or visually recorded by anyone. The only exception to this rule is that the Equity and Title IX Office, in compliance with Title IX, will record the hearing conducted under the Title IX Complaint Procedures in order to provide a verbatim record of the hearing. These recordings will be maintained by the Equity and Title IX Office. 10.0 Requests for Confidentiality or that Complaint Not Be Pursued With respect to allegations of prohibited conduct under this policy, the Title IX Coordinator and deputy coordinators make every effort to respect the concerns and goals of complainants, as well as their capacity to make independent choices regarding resolution options for addressing their complaints under this policy and the Procedures for Complaints of Sexual Misconduct Under Title IX and California Education Code. In instances where a complainant requests that their name not be used, that Caltech not pursue any action against the respondent, including an investigation, or that no disciplinary action be taken, Caltech will seriously consider the request but weigh the request against Caltech's responsibilities, including under applicable laws, to take action to provide a safe, nonthreatening, and nondiscriminatory environment for all community members, including the complainant. The Title IX Coordinator will discuss with the complainant the reasons for their requests and attempt to address the underlying concerns, such as taking steps to prevent retaliation. Where the complainant remains committed to the requests mentioned above, and the prohibited conduct falls under Section 15.0 below, the Title IX Coordinator will weigh the request against factors that may lead the Title IX Coordinator to take action on behalf of Caltech, which may be contrary to the wishes of the complainant, including potentially disclosing the complainant's name and/or proceeding to an investigation, to protect the health and safety of the General Information complainant and the Caltech community. The factors considered are within the discretion of the Title IX Coordinator and include, but are not limited to, the nature and seriousness of the alleged conduct, whether the allegations are contested, the involvement of multiple respondents, the existence of multiple or prior reports of misconduct against the respondent, whether there was a weapon, physical restraints, battery, or other violence involved, whether the use of alcohol or drugs to induce vulnerability to sexual activity without consent was allegedly involved, whether there is evidence of a pattern of conduct, the presence of other circumstances that suggest there is a significant risk that the respondent will commit further acts of prohibited conduct, the age of a complainant, whether the respondent is a faculty or staff member with oversight of students, whether there is a power imbalance between the complainant and respondent, whether the complainant believes that the complainant will be less safe if the complainant's name is disclosed or an investigation is conducted, and whether Caltech is able to conduct a thorough investigation and obtain relevant evidence in the absence of the complainant's cooperation. Where the complainant remains committed to the requests above, and the prohibited conduct does not fall under Section 15.0, but only under 16.0 and/or 17.0, the Title IX Coordinator may elect to pursue action on Caltech's behalf without considering these factors. If Caltech determines that it can honor the student's request for confidentiality, it shall still take reasonable steps to respond to the complaint, consistent with the request, to limit the effects of the alleged prohibited conduct and prevent its recurrence without initiating formal action against the alleged respondent or revealing the identity of the complainant. These steps may include increased monitoring, supervision, or security at locations or activities where the alleged misconduct occurred; providing additional training and education materials for students and employees; or conducting climate surveys regarding sexual violence. The Institute shall also take immediate steps to provide for the safety of the complainant while keeping the complainant's identity confidential as appropriate. These steps may include changing living arrangements or course schedules, assignments, or tests. The complainant shall be notified that the steps Caltech will take to respond to the complaint will be limited by the request for confidentiality. If Caltech determines that it must disclose the complainant's identity to the respondent or proceed with an investigation, it shall inform the complainant prior to making this disclosure or initiating the investigation. The complainant is not required to participate in the ensuing process. Caltech shall also take immediate steps to provide for the safety of the complainant where appropriate. In the event the complainant requests that Caltech inform the respondent that the student asked Caltech not to investigate or seek discipline, Caltech shall honor this request. If the complaint includes allegations that may constitute a possible crime, the Title IX Coordinator will notify the complainant of their right to file a criminal complaint or to choose not to notify law enforcement. 77 Institute Policies 78 As stated above in Section 6.4, Caltech does not report sex- and gender-based misconduct to law enforcement on a complainant's behalf, unless such a report is mandated by law (e.g., sexual assault of a person under 18). If the complainant chooses to notify law enforcement, they may seek the assistance of the Equity and Title IX Office to facilitate the contact with law enforcement and the scheduling of a meeting to make a report. The Title IX Coordinator, depending on facts and circumstances, may also elect to file a formal complaint and initiate an investigation even if the complainant does have the standing to do so. Formal complaints may be filed even if a complainant elects not to notify law enforcement and/or pursue a criminal complaint. All final determinations and decisions taken under this provision 10.0, except the complainant's decision to file a criminal complaint or to choose not to notify law enforcement, rest solely with the Title IX Coordinator. 11.0 Contacting Government Agencies Employees, students, and others participating in Caltech's educational programs or activities may direct questions regarding Title IX to or file complaints with the U.S. Department of Education Office for Civil Rights, (415) 486-5555, ocr.sanfrancisco@ed.gov, or (800) 421-3481, OCR@ed.gov. In addition, employees may file complaints with the California Department of Fair Employment and Housing (DFEH) at www.dfeh.ca.gov/contact-us or the United States Equal Employment Opportunity Commission (EEOC) at www.eeoc.gov. Complaints can also be directed to the Bureau for Private Postsecondary Education at bppe.ca.gov. NASA-funded program participants may file a complaint at AssistedProgramComplaint@nasa.gov or find more information at missionstem.nasa.gov/filing-a-complaint.html. NSF-funded program participants may file a complaint with the Office of Diversity and Inclusion at programcomplaints@nsf.gov, (703) 292-8020, or find more information at https://www.nsf.gov/od/odi/harassment.jsp. Participants in programs funded by other federal agencies providing federal financial assistance to Caltech may file directly with those agencies. Filing a complaint with a federal agency under Title IX must be done within 180 days of an alleged discriminatory or harassing event, and there is no requirement to exhaust remedies through (i.e., utilize or go through) Caltech's internal procedures before filing directly with a federal agency. 12.0 Clery Reporting The Clery Act requires Caltech to issue an Annual Security and Fire Safety Report, which includes crime statistics for sexual assault (rape, fondling, incest, and statutory rape), domestic violence, dating violence, and stalking. Campus Security gathers these crime statistics from the Equity and Title IX Office, security reports, Pasadena Police Department information, JPL, and reports by Campus Security authorities. Crime statistics do not disclose any identifying information General Information about the complainant, respondent, witnesses, or others. For more information and statistics for the past three years, see the current Annual Security and Fire Safety Report. SECTION III: PROHIBITED CONDUCT 13.0 Introduction to Prohibited Conduct Covered under This Policy This section sets out what conduct is prohibited under this policy. For clarity, transparency, and administrative ease, this section delineates sexual harassment prohibited under the federal Title IX regulations (Section 15.0) and under the California Education Code (Section 16.0). All such misconduct is prohibited by Caltech. Additional misconduct prohibited by Caltech and other applicable law, including attempts and threats of prohibited conduct, is described in Section 17.0. Reported behavior that does not constitute prohibited conduct under this policy but is nevertheless determined to be inappropriate pursuant to another applicable Caltech policy may subject the offending individual to disciplinary action. The term "complainant" refers to the individual who allegedly is the subject of the prohibited conduct, and "respondent" refers to the individual who is alleged to have engaged in the prohibited conduct. The complainant and respondent may sometimes be referred to collectively as the "parties" in this document and the related Procedures for Complaints of Sexual Misconduct Under Title IX and the California Education Code. The Title IX Coordinator will determine whether reported prohibited conduct is covered under the sexual harassment provisions of Title IX or constitutes other prohibited conduct as described under this policy and will apply the appropriate procedures. The Title IX Coordinator's determination will be communicated in writing to the parties. Allegations of Title IX-covered (Section 15.0) and California Education Code-covered (Section 16.0) prohibited conduct will be addressed under the Procedures for Complaints of Sexual Misconduct ("Procedures"). Where multiple allegations of prohibited conduct are at issue, and the Title IX Coordinator determines that only a portion falls within the scope of Sections 15.0 and 16.0, all of the allegations will be adjudicated under the Procedures for Complaints of Sexual Misconduct. Allegations of prohibited conduct falling exclusively under Section 17.0 will be addressed under Caltech's Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation. 14.0 Affirmative Consent Consent is a key component of various definitions of prohibited conduct. Affirmative consent is the standard of consent in Caltech's policy. Affirmative consent is the affirmative, conscious, and voluntary agreement to engage in sexual activity. ' It is the responsibility of each person involved in the sexual activity to ensure that they have the affirmative consent of the other person(s) to engage in the sexual activity. • Lack of protest or resistance does not mean consent, nor does silence mean consent. 79 Institute Policies 80 • Affirmative consent must be ongoing throughout a sexual activity and each time sexual activity is engaged in, and it can be revoked at any time. Consent to one form of sexual activity is not, by itself, consent to other forms of sexual activity. • The existence of a dating relationship between the persons involved, or the fact of any past sexual activity between them, should never by itself be assumed to be an indicator of consent. It is not a valid excuse, including in the evaluation of complaints in any resolution process, in response to an alleged lack of affirmative consent that the respondent believed that the complainant consented to the sexual activity under either of the following circumstances: The respondent's belief in affirmative consent arose from the intoxication or recklessness of the respondent. • The respondent did not take reasonable steps, in the circumstances known to the respondent at the time, to ascertain whether the complainant affirmatively consented. It is not a valid excuse that the respondent believed that the complainant affirmatively consented to the sexual activity if the respondent knew or reasonably should have known that the complainant was unable to consent to the sexual activity under any of the following circumstances: The complainant was asleep or unconscious. • The complainant was incapacitated due to the influence of drugs, alcohol, or medication, so that the complainant could not understand the fact, nature, or extent of the sexual activity. • The complainant was unable to communicate due to a mental or physical condition. A person who is incapacitated is not capable of giving effective consent to sexual activity. An incapacitated person lacks the physical and mental capacity to make informed, reasonable judgments about whether or not to engage in sexual activity. A person who is incapacitated may not be able to understand where they are, whom they are with, how they got there, or what is happening. A person may be incapacitated by a temporary or permanent mental or physical condition, sleep, or unconsciousness. A person may also be incapacitated as a result of voluntary or involuntary (e.g., induced, forced) consumption of alcohol or drugs. Incapacitation is a state beyond mere intoxication or drunkenness. Just because someone is under the influence of alcohol or drugs does not necessarily mean that a person is incapacitated. Impairment must be significant enough to render a person unable to understand the fact, nature, or extent of the sexual activity. In evaluating affirmative consent in cases involving an allegation of incapacitation, Caltech considers the state and degree of intoxication of the reporting party and the knowledge of the respondent. General Information One's own intoxication, even to the point of incapacitation, does not relieve an individual from responsibility for a policy violation when they engage in sexual conduct without the affirmative consent of the other party or parties. However, a respondent who was incapacitated during sexual conduct has the right to file a formal complaint alleging they were incapacitated and unable to consent to the reported sexual activity. ' A minor under the age of eighteen (18) is deemed to be incapable of providing affirmative consent under this policy. 15.0 Sexual Misconduct Covered under Title IX Sexual harassment is covered under Title IX if it meets the definitions and scope requirements set out in this section. NOTE: While Title IX prohibits discrimination on the basis of sex, sexual harassment is subject to specific procedures that do not apply to complaints of sex- and gender-based discrimination. Accordingly, sex- and gender-based discrimination is addressed separately below in Section 17.0 to ensure that the appropriate procedures are applied 15.1 Definition of Sexual Harassment under Title IX Sexual harassment means conduct on the basis of sex that satisfies one or more of the following: (1) an employee of Caltech conditioning the provision of an aid, benefit, or service of Caltech on an individual's participation in unwelcome sexual conduct; (2) unwelcome conduct determined by a reasonable person to be so severe, pervasive, and objectively offensive that it effectively denies a person equal access to Caltech's education program or activity; or (3) sexual assault, dating violence, domestic violence, or stalking as defined below. 15.1.1 Sexual assault means an offense classified as a sex offense under the uniform crime reporting system of the Federal Bureau of Investigation, as follows: Sex Offenses: Any sexual act directed against another person without the consent of the victim, including instances where the victim is incapable of giving consent. Rape: The penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim. This definition excludes statutory rape. Fondling: The touching of the private body parts of another person for the purpose of sexual gratification, without the consent of the victim, including in instances where the victim is incapable of giving consent because of his/her youth or because of his/her temporary or permanent mental or physical incapacity. Caltech interprets fondling to include potentially, depending on the facts and circumstances, (a) the disrobing or exposure of another without their consent, and (b) the touching of another person's private body parts for the purpose of sexual gratification without consent through clothing, as well as directly. Incest: Sexual intercourse between persons who are related to each other within the degrees wherein marriage is prohibited by law. 81 Institute Policies 82 Statutory Rape: Sexual intercourse with a person who is under the statutory age of consent, which in California is 18. 15.1.2 Dating, and Domestic Violence Dating violence means violence committed by a person who is or has been in a social relationship of a romantic or intimate nature with a complainant. The existence of such a relationship shall be determined based on the complainant's statement as well as consideration of the length of the relationship, the type of relationship, and the frequency of interaction between the persons involved in the relationship. Dating Violence includes, but is not limited to, sexual or physical abuse or the threat of such abuse. Dating Violence does not include acts covered under the definition of Domestic Violence Domestic violence means conduct, on the basis of sex, that constitutes a felony or misdemeanor crime of violence committed upon a victim who is (a) the offender's spouse or former spouse, (b) the offender's cohabitant or former cohabitant; or (c) the offender's fiancé or fiancée, or someone with whom the offender has, or previously had, an engagement or dating relationship; (d) the parent of the offender's child; or (5) any other victim who is protected under the domestic or family violence laws of the state where the domestic violence occurred. 15.1.3 Stalking means engaging in a course of conduct directed at a specific person that would cause a reasonable person to fear for his or her safety or the safety of others; or suffer substantial emotional distress. "Course of conduct" means two or more acts, including, but not limited to, acts in which the stalker directly, indirectly, or through third parties, by any action, method, device, or means, follows, monitors, observes, surveils, threatens, or communicates to or about a person, or interferes with the person's property. "Reasonable person" means a reasonable person under similar circumstances and with similar legally protected or other characteristics to the victim. Stalking is also covered by the Violence Prevention policy and should be reported to the Equity and Title IX Office and Security at campus or the Protective Services Office at JPL. Making an audio or video recording of an individual without their consent is prohibited and may constitute stalking under this policy or the Violence Prevention Policy. 15.2 Scope of Requirements for Title IX Sexual Harassment Title IX addresses sexual harassment in an education program or activity of Caltech against a person in the United States. At the time of filing a formal complaint, a complainant must be participating in or attempting to participate in an education program or activity of Caltech. The term "attempting to participate" includes when a complainant has: (a) applied for admission; (b) graduated but intends to apply for a new program; (c) graduated but intends to participate in alumni programs and activities; (d) gone on leave but is still enrolled; (e) gone on leave but intends to re-apply after the leave; (f) withdrawn General Information due to alleged sexual harassment and expresses a desire to re-enroll if Caltech responds appropriately to the allegations. The term "education program or activity" includes buildings or other locations that are part of the school's operations, including remote learning platforms; (b) locations, events, or circumstances, even if off-campus, over which Caltech exercised substantial control over both the respondent and the context in which the alleged sexual harassment occurred; and (c) any building, even if off-campus, owned or controlled by a student organization that is officially recognized by Caltech. 15.3 Limitation on Claiming Consent as a Defense to Sexual Harassment When a consensual personal relationship arises and a power differential exists, Caltech does not consider consent as a defense to a claim of sexual harassment. The individual in the relationship with greater power will be held responsible. 16.0 Sexual Misconduct Covered under the California Education Prohibited conduct under this policy is covered under the California Education Code (CEC) if it meets any of the definitions of sexual assault, dating violence, domestic violence, and stalking under Section 15.0, and sexual harassment set out below in this section. 16.1 Definition of Sexual Harassment under the CEC Sexual harassment means unwelcome sexual advances, requests for sexual favors, and other verbal, visual, or physical conduct of a sexual nature, made by someone from or in the work or educational setting, under any of the following conditions: (1) Submission to the conduct is explicitly or implicitly made a term or a condition of an individual's employment, academic status, or progress. (2) Submission to, or rejection of, the conduct by the individual is used as the basis of employment or academic decisions affecting the individual. (3) The conduct has the purpose or effect of having a negative impact upon the individual's work or academic performance, or of creating an intimidating, hostile, or offensive work or educational environment. Verbal sexual harassment includes but is not limited to unwelcome epithets, comments, or slurs of a sexual nature. Visual sexual harassment includes but is not limited to derogatory posters, cartoons, drawings, obscene gestures, or computer-generated images of a sexual nature. Physical sexual harassment includes but is not limited to assault, impeding or blocking movement, or any other physical interference with work or academic activities or movement when directed against an individual on the basis of sex. When an individual sexually harasses a student, the harassing conduct creates a hostile environment on campus for the purposes of 83 Institute Policies 84 this section if the conduct is sufficiently serious that it interferes with or limits a student's ability to participate in or benefit from the institution's programs or activities. The more severe the conduct, the less need there is to show a repetitive series of incidents to prove a hostile environment on campus, particularly if the harassment is physical. A single or isolated incident of sexual harassment, including sexual violence, may create a hostile environment on campus if the incident is sufficiently severe. (4) Submission to, or rejection of, the conduct by the individual is used as the basis for any decision affecting the individual regarding benefits and services, honors, programs, or activities available at or through the educational institution. (5) Sexual violence, which means physical sexual acts perpetrated against a person without the person's affirmative consent, including rape and sexual battery. (6) Rape, which is defined as penetration, no matter how slight, of the vagina or anus with any part or object, or oral copulation of a sex organ by another person, without the consent of the victim. (7) Sexual battery, which means the (a) intentional touching, directly or through clothing, of another person's intimate parts without consent, (b) intentionally causing a person to touch the intimate parts of another, directly or through clothing, without consent, or (c) using a person's own intimate part to intentionally touch another person's body, directly or through clothing, without consent. Intimate body parts are the breast, genitals, groin, anus, or buttocks. (8) Sexual exploitation, which means a person taking sexual advantage of another person for the benefit of anyone other than that person without that person's consent, including, but not limited to, any of the following acts: (a) The prostituting of another person. (b) The trafficking of another person, defined as the inducement of a person to perform a commercial sex act, or labor or services, through force, fraud, or coercion. (c) The recording of images, including video or photograph, or audio of another person's sexual activity or intimate parts, without that person's consent. (d) The distribution of images, including video or photograph, or audio of another person's sexual activity or intimate parts, if the individual distributing the images or audio knows or should have known that the person depicted in the images or audio did not consent to the disclosure. (e) The viewing of another person's sexual activity or intimate parts, in a place where that other person would have a reasonable expectation of privacy, without that person's consent, for the purpose of arousing or gratifying sexual desire. General Information 16.2 Limitation on Claiming Consent as a Defense to Sexual Harassment When a consensual personal relationship arises and a power differential exists, Caltech does not consider consent as a defense to a claim of sexual harassment. The individual in the relationship with greater power will be held responsible. 17.0 Additional Conduct Prohibited by Caltech This section lists and describes additional misconduct prohibited by Caltech, and under applicable law, but that is not subject to the Procedures for Complaints of Sexual Misconduct. Complaints of such prohibited conduct will be addressed under the Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation. 17.1 Prohibition on Sex- or Gender-Based Discrimination Sex- and Gender-Based Discrimination constitutes prohibited conduct under this policy. Sex discrimination under Title IX occurs when a person in the United States, on the basis of actual or perceived sex, is excluded from participation in, or is denied the benefits of, or is subjected to discrimination, under any Caltech education program or activity. The term "education program or activity" encompasses all of the operations of Caltech. Sex- or gender-based discrimination also includes unfavorable treatment on the basis of sex, gender, gender identity, gender expression, and sexual orientation. Gender expression means a person's gender-related appearance and behavior, whether or not stereotypically associated with the person's assigned sex at birth. 17.2 Prohibition on Sexual and Gender-Based Harassment Sex-based and gender-based harassment is harassment based on an individual's actual or perceived sex, gender, gender identity, or gender expression, including harassing or bullying conduct based on the individual's gender expression, gender identity, transgender status, gender transition, or nonconformity with sex stereotypes. 17.3 Prohibition on Relationships between Employees and Undergraduates This policy prohibits sexual or romantic relationships between an undergraduate student and a faculty member, postdoctoral scholar, or staff member. Any Responsible Employee who becomes aware of Coordinator. The non-undergraduate party in the relationship will be held responsible for prohibited conduct violating this policy, regardless of whether a complaint is filed. 85 Institute Policies 86 17.4 Prohibition on Evaluative Responsibilities in Certain Circumstances Even when relationships are consensual, care must be taken to eliminate the potential for harassment or other conflicts. Caltech practice, as well as more general ethical principles, prohibits individuals from participating in evaluating the work or academic performance of those with whom they have romantic and/or sexual relationships, or from making hiring, salary, or similar decisions regarding those individuals. Upon learning about a consensual relationship involving such a power differential, the supervisor, dean, or division chair should immediately notify the Title IX Coordinator and, in consultation with the Title IX Coordinator, should review and remedy any direct administrative or academic relationship between the involved individuals. The individual with greater power may be subject to disciplinary action for a violation of this prohibition. 17.5 Prohibition on Inequitable Treatment Stemming from Consensual Relationships Even when relationships are consensual, care must be taken to eliminate the potential for harassment or other conflicts. If a consensual relationship exists, it is not acceptable to treat the individual in the relationship more favorably than other similarly situated individuals in the context of employment or academic performance. 17.6 Prohibition on Uncompleted Attempts or Threats of Prohibited To the extent that uncompleted attempts or threats of prohibited conduct are not covered in Sections 15.0 and 16.0 of this policy, they are covered in Section 17.0. Threats of prohibited conduct may also constitute retaliation under this policy. 17.7 General Caution about Maintaining Appropriate Professional Boundaries All members of the Caltech community should maintain respectful and professional boundaries with one another. This is particularly important when Caltech employees, whether faculty, postdoctoral scholars, or staff, interact with their subordinates, or with graduate and undergraduate students, due to the power differential that exists between them. While certain conduct may not constitute prohibited conduct, it can create situations where students or others feel uncomfortable but reluctant to voice that sentiment. Depending on the circumstances, such situations may include hosting students at private homes, sharing lodging on academic-related trips (e.g., conferences, field trips), wearing swimsuits (e.g., marine research outing), and any interaction where alcohol is consumed (e.g., dinners at conferences, field trips, holiday parties). Caltech encourages employees and other community members to think carefully about maintaining appropriate professional boundaries General Information at all times, to state their boundaries as appropriate, and to consider seeking guidance from the Title IX Coordinator. 18.0 Examples of Prohibited Conduct The following illustrative examples are provided to help prevent inappropriate behavior and are not evidence that similar allegations would automatically constitute that particular type of prohibited conduct. The examples below may constitute prohibited conduct, depending on the specific facts and circumstances. 18.1 Sex- or Gender-Based Discrimination • Denying an employee a promotion because they are openly gay and some of the team who would be reporting to them strike you as somewhat conservative and you worry that the employee might not feel comfortable supervising them • Rejecting a student from House membership because some students feel uncomfortable with the student's openness about their recent gender transition • Rejecting a faculty candidate after a hiring team member opined that the candidate's voice and mannerisms are too high-pitched and animated to be perceived as sufficiently professional and authoritative to run a lab effectively • Telling a masculine-presenting nonbinary individual that they cannot wear makeup or wear feminine clothing in the workplace 18.2 Sexual or Gender-Based Harassment • Sending unwanted sexually-oriented jokes to a student or work group email list or other group communication mediums (e.g., Slack, Teams) • Displaying explicit sexual pictures in common areas of Institute housing or on a work computer station where others can view it • Making or using derogatory comments, epithets, slurs, or jokes of a gender-based or sexual nature • Ostracizing individuals from group activities because of their sex, gender or gender identity, gender expression, or sexual orientation, or because they objected to harassing behavior • Threatening to "out" someone's deadname or sexual orientation • Making unwelcome graphic comments about an individual's body, using sexually degrading words to describe an individual • Engaging in unwanted suggestive or obscene communications • Engaging in unwelcome touching, fondling, or groping of a sexual nature Making unwanted sexual advances • Promising a benefit to someone in exchange for engaging in sexual activity • Exposing one's genitals to another without consent 87 Institute Policies 88 18.3 Sexual Exploitation • Observing, recording, viewing, distributing, or allowing another to observe, record, view, or distribute intimate or sexual images of another individual without that individual's consent • Surveillance and other types of observations of intimate or highly personal activities, whether by physical proximity or electronic means, live or by a camera, such as watching a person undressing, showering, or engaging in sexual activity • Taking steps to cause drunkenness or incapacitation by alcohol or drugs in order to make another person vulnerable to any degree of sexual activity • Sexually based stalking or bullying, including by electronic means • Offering someone for sexual activity in exchange for a benefit or payment • Abuse of a position of vulnerability, power differential, or trust for sexual purposes • Disrobing or exposure of another without their consent 18.4 Stalking • Repeated unwanted communication, including face-to-face contact, telephone calls, voice messages, emails, text messages, postings on social networking sites, written letters, or gifts • Posting picture(s) or information of a sexual nature on social networking sites or other websites • Gathering information about the person through the use of public records, online searches, going through the garbage, or contacting the person's family, friends, or co-workers • Posting private pictures or videos on school bulletin boards or internet sites • Installing spyware on another person's personal devices, including phones or computers • Surveillance or other types of observation, including staring or peeping • Pursuing, following, or showing up uninvited at or near places like classrooms, residence, workplace, or other places frequented by the person • Directly or indirectly making threats to the person • Inducing friends, family members, or other persons to engage in any of the above conduct • Inducing friends, family members, or other persons to track and report on the person's whereabouts and activities 19.0 Informational Resources Information on prohibited conduct, as well as copies of Caltech's Sex-and Gender-Based Misconduct; Nondiscrimination and Equal Employment Opportunity; Unlawful Harassment; and Violence Prevention policies are available from the following resources: At Campus: Caltech's Title IX Coordinator and deputy Title IX Coordinators, Caltech's EO Coordinators, Human Resources, Student Affairs, the Deans' Offices, the Caltech Center for Inclusion and Diversity, Resident Associates, the Staff and Faculty Consultation General Information Center, and Employee and Organizational Development.

Introduction and Scope Caltech's Sex and Gender-based Misconduct Policy reflects Caltech's commitment to support and encourage individuals who have been subjected to prohibited conduct to come forward. Caltech takes all allegations of prohibited conduct seriously and responds appropriately. Caltech will take prompt and appropriate action to address all reports of prohibited conduct in a fair and impartial manner. Complainants, respondents, and all other participants in the process will be treated with dignity, care, and respect. Caltech's policy and these procedures are intended to ensure that individuals accused of engaging in prohibited conduct are not prejudged; that they have notice and a full and fair opportunity to respond to allegations before findings and conclusions are reached; and that decisions are based on the evidence gathered in a process that is fair to both complainants and respondents when an investigation is conducted. Caltech will conduct a fair, impartial, timely, and thorough investigation that provides all parties with appropriate due process. Consistent with Section 6.0 of the Sex- and Gender-Based Misconduct Policy, Caltech encourages students and other members of its community who are not designated Responsible Employees to report to the Title IX Coordinator sexual harassment and other misconduct by third parties (i.e., report situations on behalf of others). The contact information for the Title IX Coordinator and Deputy Coordinators and methods of reporting are fully provided in Section 6.0 of the policy. Reporting options include contacting the Title IX Coordinator by email (equity@caltech.edu), telephone (626-395-3130), in-person visit (Center for Student Services, 414 S. Holliston Avenue, Suite 205), and the online report form which can be submitted anonymously. Caltech will respond to any such reports to address or prevent a hostile educational environment or to ensure a student's 89 Institute Policies 90 access to education. Notice of the Sex-and Gender-Based Misconduct Policy and these Sexual Misconduct Procedures, which include information on where and how reports and complaints may be filed, is provided to all Caltech students on the Equity and Title IX Office website on the Resources page as well as by email at the start of the academic year. These procedures are to be applied, when both parties are covered persons, to address allegations of prohibited conduct that (a) fall within the scope, as set out in Section I, 2.0, of the Sex- and Gender-Based Misconduct Policy, and (b) fall within the definitions of sexual harassment, as defined by Title IX and the California Education Code and set out in Sections 15.0 or 16.0, respectively, of the Caltech Sex- and Gender-Based Misconduct Policy (policy). All other prohibited conduct under the policy is addressed under the Procedures for Unlawful Discrimination, Harassment, and Retaliation. The Title IX Coordinator determines whether these procedures apply. Throughout these procedures, any reference to a Caltech or JPL administrator is understood to include not only that administrator but also their designee. Information, including statistics, concerning the prevalence of sexual harassment and sexual violence in the educational setting and the differing rates at which students experience such misconduct based on race, gender, gender identity, sexual orientation, and disability can be found on Caltech's Equity and Title IX Office website. on the Resources/Policies page, under Reports. See Association for American Universities Campus Climate Survey 2019 and the National Academies of Science Engineering and Medicine 2018 Report on Sexual Harassment of Women. AAU survey data is also provided on Caltech's Institutional Research Office website. II. Retaliation Retaliation against any member of the Caltech community at any point in time for making a good-faith report of prohibited conduct or participating or refusing to participate in any manner in an investigation, proceeding, or hearing conducted by Caltech or a state or federal agency, is strictly prohibited. Retaliation is defined as overt or covert acts of reprisal, interference, discrimination, intimidation, or harassment against an individual or group for exercising their rights under Title IX or other federal and state laws. Threats of retaliatory action also constitute retaliation. Retaliation violates this policy and is unlawful. Caltech will maintain the confidentiality of persons involved in reports and complaints of prohibited conduct, except as required or allowed under the Sex- and Gender-Based Misconduct Policy, these procedures, the Unlawful Harassment Policy and related procedures, or federal or state law. The following actions do not constitute retaliation: the exercise of rights protected under applicable law or charging an individual with a code of conduct violation for making a materially false statement in bad faith in the course of a resolution process. However, a General Information determination that a respondent was or was not responsible for alleged prohibited conduct, alone, is not sufficient to conclude that any party made a materially false statement in bad faith. Allegations of retaliation that are alleged at the time of a formal complaint of sexual harassment, as defined in policy Sections 15.0 and 16.0. will be addressed as part of that complaint. Complaints of retaliation that are not alleged at the time of a sexual harassment complaint will be addressed under the Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation. The Title IX Coordinator will have the ultimate discretion over which procedures apply to a claim of retaliation. Ill. Adviser or Support Person The complainant and respondent may have an adviser or support person (hereinafter, collectively, "adviser") of their choice (other than a witness), including a victim advocate or an attorney, accompany and generally support them at any virtual or live meetings or phone calls at any point in the procedures discussed below. However, Caltech resolution processes, including the investigation process, are not legal proceedings and the adviser may not speak or submit written statements on behalf of the individual they are advising, other than at the hearing as described below in Section XIII(D)(8). Caltech will be responsible for communicating information to advisers, or scheduling meetings around advisers' availability, except to the extent required to comply with Section XIII(D)(8) of these procedures. Advisers are required to sign and abide by Caltech's Adviser Policy and Confidentiality Agreement setting forth the parameters of their role. The role of the adviser is to (a) provide general support to a party participating in any step of the processes outlined below, (b) encourage the party whom the adviser supports to communicate for themself, and (c) respect the process and procedures. All communications, whether oral or written, will be between the Equity and Title IX Office staff members), investigators), or other appropriate participating administrators), or their designees, ("Title IX process administrators"), and the party only. The adviser may not speak during any meeting, including on behalf of the party whom they support, ask questions of the administrators) or of the party whom they support, or otherwise interfere with or disrupt the meeting, conversation, or procedure. Nor may an adviser communicate on behalf of the party in emails or other correspondence with the Equity and Title IX Office. However, during meetings, the adviser may provide written notes or instructions to the party whom they support. All parties have the right to consult with an attorney at their own expense, at any procedural step set forth below, if they wish to do so. An attorney may serve, but is not required to serve, as an adviser. Caltech is not required to identify or provide advisers to parties, except as provided below in Section XIII(D)(8). 91 Institute Policies 92 IV. Timelines These procedures set forth reasonably prompt time frames for major procedural stages. The Title IX Coordinator, at their own discretion or upon the request of a party or witness, may extend a time frame for good cause, providing prompt written notice to the parties of any delays or extensions and the reasons therefor. Good cause may include but is not limited to the absence of a party, a party's adviser, or a witness; concurrent law enforcement activity; the need for language assistance or accommodation of disabilities; the breadth and scope of the allegations, in terms of content and date, the number of potential witnesses, the amount of available, relevant documentary evidence; the need to conduct a thorough, fair, and accurate investigation; and office closures. The Title IX Coordinator shall not unreasonably deny a party's request for an extension of a deadline related to a complaint during periods of examinations or school closures. V. Initial Title IX Assessment Within 14 days of receiving a report of prohibited conduct, Caltech's Title IX Coordinator will make an initial assessment of the report to determine the following: 1. a reasonable assessment of any safety concerns posed to any member of the Caltech community or Caltech's campus; 2. whether the allegations on their face present a potential violation of the Sex- and Gender-Based Misconduct Policy, and if so, whether they are covered under these procedures or under Caltech's Unlawful Discrimination, Harassment, and Retaliation procedures; or, if not, whether they should be addressed under a different Caltech policy and process; 3. whether and what supportive measures are warranted; and 4. whether emergency removal is warranted. The Title IX Coordinator or their designee will promptly reach out (in writing, to the extent appropriate) to each identifiable complainant or alleged victim of the report to inform them, as appropriate, of the receipt of the report, discuss the availability of supportive measures, consider their wishes with respect to supportive measures, inform them that supportive measures are available with or without the filing of a formal complaint, and explain to them the process for filing a formal complaint and the importance of preserving evidence and identifying witnesses and their locations. The Title IX Coordinator's outreach will also include a statement that retaliation for filing a complaint or participating in a resolution process, or both, is prohibited by Caltech policy and federal and California law. The Title IX Coordinator will provide them a copy of these Sexual Misconduct Procedures. Where a crime may have occurred, the Title IX Coordinator will provide the complainant/alleged victim notice of their right, but not the obligation, to report the matter to law enforcement and information on how Caltech can help facilitate such reporting. The General Information Title IX Coordinator will also describe how Caltech responds to reports of prohibited conduct, as well as potential disciplinary consequences. The Title IX Coordinator will also refer them to and help coordinate, if desired, support resources, including providing information on the availability of and contact information for on-campus and off-campus resources and services. Finally, the Title IX Coordinator will request for the complainant/alleged victim to meet with them to discuss options for responding to the report. The Title IX Coordinator may also meet with the respondent and other relevant individuals in order to make an initial assessment. The respondent also will be offered the opportunity to request and receive supportive measures at this time. The complainant and the respondent will be provided with the following: • Information on their rights and options under the Sex- and Gender-Based Misconduct or Unlawful Harassment policies and related procedures as appropriate, and copies of these documents • Written materials outlining information on on-campus and off-campus support resources • and services, including contact information and days and hours of availability, as well as information on coordination with law enforcement • Information on the importance of and policy concerning evidence preservation • Information on the policy against retaliation for filing a complaint or participating in a complaint process VI. Supportive Measures Supportive measures are non-disciplinary, nonpunitive individualized services offered as appropriate and reasonably available to the parties before or after the filing of a formal complaint or where no formal complaint has been made or no investigation has been undertaken. Supportive measures are available to parties regardless of whether they participate in a resolution process. They are designed to restore or preserve equal access to Caltech's education program or activity without unreasonably burdening the other party, including measures designed to protect the safety of all parties or Caltech's educational environment, or to deter prohibited conduct. Supportive measures may include counseling, academic accommodations (e.g., extensions of deadlines, course-related adjustments), modifications of work or class schedules, campus escort services, mutual restrictions on contact between the parties, including in a virtual or electronic environment, changes in work or housing locations, leaves of absence, increased security and monitoring of certain areas of campus, referrals to campus and off-campus support resources, and other similar measures. Caltech will maintain as confidential any supportive measures provided to any party to the extent such confidentiality does not impair Caltech's ability to provide the supportive measures (e.g., notifying appropriate 93 Institute Policies 94 administrators involved in academic accommodations). The Title IX Coordinator will coordinate the effective implementation of supportive measures. Academic accommodations should be requested in a timely manner, reasonably in advance of deadlines. Retroactive accommodations, such as re-taking tests or extensions after the due date has passed, will not be granted. Supportive measures affecting faculty, postdoctoral scholars, and staff, including employees at JPL, might include transfer of supervisory or evaluative responsibility regarding grading, supervision, tenure review, letters of recommendation, and/or changes to office assignments. Caltech will endeavor to minimize the burden on the party receiving supportive measures without unreasonably burdening the other party. If a complainant wishes to seek a temporary restraining order or similar judicial order, Caltech will help the complainant with that process. Parties may seek the assistance of the Campus Sexual Violence Advocate, who can be contacted directly or through the Equity and Title IX Office. When requested by a complainant or otherwise determined to be appropriate, Caltech will issue a mutual no-contact order. Caltech will not issue such an order automatically but instead shall consider the specific circumstances of each case to determine whether the order is necessary or justifiable to protect the non-complaining party's safety or well-being, or to respond to interference with a resolution process. Upon the issuance of a mutual no-contact order, Caltech will provide the parties with a written justification for the order, an explanation of its terms, and the circumstances, if any, under which violation could be subject to disciplinary action. Moreover, Caltech shall consider and respond to requests for accommodations relating to prior incidents of sexual harassment that could contribute to a hostile educational environment or otherwise interfere with a student's access to education where both individuals are, at the time of the request, subject to Caltech's policies. The imposition of supportive measures is not indicative of a determination of responsibility or any other outcome. These measures may be modified at any time and may be kept in place after a final investigative decision is reached. All parties are expected to comply with any supportive measures that may be imposed. Failure to comply with supportive measures may be grounds for disciplinary action. A party may be subject to discipline under the appropriate Caltech policy for failure to comply with a supportive measure even if they are found not responsible for the underlying report of prohibited conduct. NOTE: The Institute may undertake remedies and systemic remedies set forth below in Section XIII(D)(9) (Potential Sanction, Remedies, and Systemic Remedies), as appropriate and consistent with the requirements of Title IX and this Section VI, to safeguard a complainant's access to education, at any time. The complainant's engagement in a resolution process is not a prerequisite for such action by Caltech. General Information VII. Emergency Removal The Title IX Coordinator will undertake an individualized safety and risk analysis for the purpose of determining whether the respondent, based on the alleged conduct, is an immediate threat to the physical health or safety of any student or other individual, justifying their removal. The Title IX Coordinator may consult with any individuals they consider pertinent and appropriate to making the emergency removal determination. The safety and risk factors that the Title IX Coordinator will consider include but are not limited to the nature of the allegations, the alleged number and age of the complainant(s), the power differential between the respondent and complainants), whether the respondent is alleged to have used a weapon, violence, drugs, or alcohol to intimidate, harm, or control a complainant, and whether the allegations present a pattern of behavior or otherwise suggest a likelihood of repeated misconduct. Where the Title IX Coordinator has determined that emergency removal of a student respondent is appropriate, the respondent will be provided with notice and an opportunity to challenge the decision immediately following the removal. To challenge a removal decision by the Title IX Coordinator, the respondent must submit a written appeal to the associate vice president for human resources within seven (7) calendar days of receipt of notice. In deciding this appeal, the associate vice president for human resources may consult with any individuals they consider pertinent and appropriate to making the decision. The decision of the associate vice president for human resources is final. Caltech may place nonstudent employee respondents on administrative leave while a complaint resolution process is pending. VIII. Complainant's Ability to Exercise Options With respect to allegations of prohibited conduct under the Sex- and Gender-Based Misconduct Policy, the Title IX Coordinator and deputy coordinators make every effort to respect the concerns and goals of complainants, as well as their capacity to make independent choices regarding resolution options for addressing their complaints under the policy and these procedures. In instances where a complainant requests that their name not be used, that Caltech not pursue any action against the respondent, including an investigation, or that no disciplinary action be taken, Caltech will seriously consider the request but weigh the request against Caltech's responsibilities, including under applicable laws, to take action to provide a safe, nonthreatening, and nondiscriminatory environment for all community members, including the complainant. The Title IX Coordinator will discuss with the complainant the reasons for their requests and attempt to address the underlying concerns, such as taking steps to prevent retaliation. Where the complainant remains committed to the requests mentioned above, and the prohibited conduct falls under Section 15.0 below, the Title IX Coordinator will weigh the request against factors that may lead the Title IX Coordinator to take action on behalf of Caltech, which may be contrary to the wishes of the complainant, 95 Institute Policies 96 including potentially disclosing the complainant's name and/or proceeding to an investigation, to protect the health and safety of the complainant and the Caltech community. The factors considered are within the discretion of the Title IX Coordinator and include, but are not limited to, the nature and seriousness of the alleged conduct, whether the allegations are contested, the involvement of multiple respondents, the existence of multiple or prior reports of misconduct against the respondent, whether there was a weapon, physical restraints, battery, or other violence involved, whether the use of alcohol or drugs to induce vulnerability to sexual activity without consent was allegedly involved, whether there is evidence of a pattern of conduct, the presence of other circumstances that suggest there is a significant risk that the respondent will commit further acts of prohibited conduct, the age of a complainant, whether the respondent is a faculty or staff member with oversight of students, whether there is a power imbalance between the complainant and respondent, whether the complainant believes that the complainant will be less safe if the complainant's name is disclosed or an investigation is conducted, and whether Caltech is able to conduct a thorough investigation and obtain relevant evidence in the absence of the complainant's cooperation. Where the complainant remains committed to the requests above, and the prohibited conduct does not fall under Section 15.0, but only under 16.0 and/or 17.0, the Title IX Coordinator may elect to pursue action on Caltech's behalf without considering these factors. If Caltech determines that it can honor the student's request for confidentiality, it shall still take reasonable steps to respond to the complaint, consistent with the request, to limit the effects of the alleged prohibited conduct and prevent its recurrence without initiating formal action against the alleged respondent or revealing the identity of the complainant. These steps may include increased monitoring, supervision, or security at locations or activities where the alleged misconduct occurred; providing additional training and education materials for students and employees; or conducting climate surveys regarding sexual violence. The Institute shall also take immediate steps to provide for the safety of the complainant while keeping the complainant's identity confidential as appropriate. These steps may include changing living arrangements or course schedules, assignments, or tests. The complainant shall be notified that the steps Caltech will take to respond to the complaint will be limited by the request for confidentiality. If Caltech determines that it must disclose the complainant's identity to the respondent or proceed with an investigation, it shall inform the complainant prior to making this disclosure or initiating the investigation. The complainant is not required to participate in the ensuing process. Caltech shall also take immediate steps to provide for the safety of the complainant where appropriate. In the event the complainant requests that Caltech inform the respondent that the student asked Caltech not to investigate or seek discipline, Caltech shall honor this request. General Information If the complaint includes allegations that may constitute a possible crime, the Title IX Coordinator will notify the complainant of their right to file a criminal complaint or to choose not to notify law enforcement. Caltech does not report sex- and gender-based misconduct to law enforcement on a complainant's behalf, unless such a report is mandated by law (e.g., sexual assault of a person under 18, de-identified reporting as required under California Education Code Section 67383). If the complainant chooses to notify law enforcement, they may seek the assistance of the Equity and Title IX Office. The Equity and Title IX Office will facilitate the contact with law enforcement and the scheduling of a meeting, if the complainant chooses to make a report. The Title IX Coordinator, depending on facts and circumstances, may also elect to file a formal complaint and initiate an investigation even if the complainant does not have standing to do so. Formal complaints may be filed even if a complainant elects not to notify law enforcement and/or pursue a criminal complaint. All final determinations and decisions taken under this provision 10.0, except the complainant's decision to file a criminal complaint or to choose not to notify law enforcement, rest solely with the Title IX Coordinator. IX. Filing a Formal Complaint In order to exercise resolution options for addressing and resolving complaints of alleged prohibited conduct covered under these procedures, the complainant must file a formal complaint document with the Title IX Coordinator in person or by regular or electronic mail requesting that Caltech initiate a complaint resolution process. The document must contain the complainant's physical or digital signature or otherwise indicate that the complainant is the person filing the formal complaint. At the time of filing a formal complaint, a complainant must be participating in or attempting to participate in an education program or activity of Caltech. The term "attempting to participate" includes when a complainant has: (a) applied for admission; (b) graduated but intends to apply for a new program; (c) graduated but intends to participate in alumni programs and activities; (d) gone on leave but is still enrolled; (e) gone on leave but intends to re-apply after the leave; or (f) withdrawn due to alleged sexual harassment and expresses a desire to re-enroll if Caltech responds appropriately to the allegations. The term "education program or activity" includes prohibited conduct occurring in locations, events, or circumstances, on or off-campus, over which Caltech exercised substantial control over both the respondent and the context in which the alleged prohibited conduct occurred, and also includes any building owned or controlled by a student organization that is officially recognized by Caltech. For reports of conduct occurring off-campus, the Title IX Coordinator will determine whether the alleged prohibited conduct occurred in a Caltech education program or activity. However, even if a complainant is not qualified to bring a formal complaint, the respondent is outside the jurisdiction of Caltech's 97 Institute Policies 98 policy, or the alleged prohibited conduct took place outside of Caltech's educational programs and activities, if there is any reason to believe that the alleged prohibited conduct could contribute to a hostile educational environment, interfere with a student's access to education, or otherwise compromise the safety of the Caltech community, Caltech will still take prompt action, as warranted and appropriate, to provide for the safety and well-being of the individual reporting and the campus community, including taking reasonable steps to stop and remedy the effects of the prohibited conduct and to prevent recurrence of the behavior. This may include the Title IX Coordinator's initiating a formal complaint under their own authority on Caltech's behalf. Where the Title IX Coordinator initiates activity under their own authority, as authorized under Policy Section 10.0 and reiterated above in Section VIII of these procedures, the formal complaint requirements must still be met. Formal complaints may be filed even if a complainant elects not to notify law enforcement and/or pursue a criminal complaint. X. Consolidation of Formal Complaints The Title IX Coordinator may consolidate formal complaints of allegations covered under these procedures against more than one respondent, or by more than one complainant against one or more respondents, or by one party against the other party, where the allegations arise out of the same facts or circumstances. XI. Notice of Allegations Upon receiving or initiating a formal complaint, within fourteen (14) calendar days, the Title IX Coordinator must provide written notice to the parties of the following, with sufficient time for the parties- generally fourteen (14) calendar days— to prepare a response before any initial interview: 1. resolution processes set out below; 2. allegations, including sufficient details known at the time, including the identities of the parties involved in the incident, if known, the misconduct alleged, and the date and location of the alleged incident, if known; 3. alleged institute policy violations under review; 4. procedures that will be used; 5. statement that the respondent is presumed not responsible for the alleged misconduct (i.e., innocent) and that a determination regarding responsibility is made at the conclusion of an investigation process or by an administrative resolution in which the respondent takes responsibility for the alleged misconduct; 6. that the parties may have an adviser of their choice, who may be, but is not required to be, an attorney, accompany them at any stage of the process; 7. that the parties may review and inspect evidence under an investigation process; and that knowingly making false statements or submitting false information is prohibited and may General Information subject the offending party to discipline; 8. information regarding appropriate counseling and other support resources developed and maintained by the Institute; 9. copies of the policy and pertinent procedures. Any new allegations that arise during the course of the investigation that could subject either party to new or additional sanctions shall be subject to these same notice requirements. XII. Dismissal of a Formal Complaint Upon receiving a formal complaint, within fourteen (14) calendar days, the Title IX Coordinator must dismiss the complaint for resolution under these procedures if the conduct alleged does not constitute sexual harassment, as defined either under Title IX (policy Section 15.0) or the CA Education Code (policy Section 16.0). If the conduct alleged does not fall under either section, the Title IX Coordinator, if appropriate, will refer the allegations for resolution under other appropriate Caltech policies and procedures, including the Unlawful Harassment Policy and related procedures. The Title IX Coordinator may also dismiss a formal complaint or allegations therein if at any time during a resolution process a complainant notifies the Title IX Coordinator in writing that they would like to withdraw their complaint or certain allegations; if the respondent is no longer enrolled or employed at Caltech; or if, as determined by the Title IX Coordinator, specific circumstances prevent Caltech from gathering evidence sufficient to reach a determination as to the complaint or certain allegations. The Title IX Coordinator will promptly and simultaneously send written notice to the parties of any dismissal and the reason(s) for the dismissal. The parties may submit an appeal of any dismissal decision, in writing, to the associate vice president of human resources, within seven (7) calendar days of receiving the dismissal decision. This appeal of a dismissal of a formal complaint, or of certain allegations therein, is limited to one or more of the following grounds: a procedural irregularity that affected the dismissal decision; new evidence (including a new witness) that was not reasonably available at the time of the dismissal decision that could affect that decision; and the Title IX Coordinator, investigators), or decision makers) had a conflict of interest or bias for or against complainants or respondents generally or the individual complainant or respondent that affected the dismissal decision. If a party submits an appeal of a dismissal, the other party will have the opportunity to submit a written response to the appeal within ten (10) calendar days of the filing of the appeal. The parties simultaneously will be informed, in writing, of the outcome of the appeal. The appeal decision letter will state the rationale for the result. Appeal decisions are final. Even where dismissal of a formal complaint occurs, the Title IX Coordinator may still provide supportive measures to parties or take other appropriate action in response to alleged concerns. 99 Institute Policies 100 XIII. Resolution Options The outcomes of each of the three options set out below-the remedy-based resolution, the administrative resolution, and the investigation, subject to any appeal process - are considered final. In other words, once one option has concluded, a party may no longer exercise another option regarding the same alleged conduct. However, a party may elect to raise or pursue another option before the option currently being pursued has concluded. Under any of the three options, remedies must be designed to restore or preserve equal access to Caltech's education program or activity. They may include actions that qualify as supportive measures, but unlike supportive measures, remedies may include actions that are disciplinary, punitive, or burden the other party. Any person designated by Caltech to facilitate any of the resolution processes set out below (e.g., Title IX Coordinator, investigators, decision maker, administrators who determine sanctions and remedies, administrator hearing an appeal of an outcome of an investigation process) may not have a conflict of interest or bias for or against complainants or respondents generally or an individual complainant or respondent. Parties will be provided an opportunity at appropriate junctures in a process to object to a person carrying out a facilitation role in the process for the consideration and decision of the Title IX Coordinator on the grounds of a conflict of interest or bias. Where an objection is made about the Title IX Coordinator, the decision as to their suitability will be made by the associate vice president for human resources. Any consideration of impartiality, or objections based on conflict of interest or bias, of those involved in Title IX processes must be reviewed with thoughtful consideration of individual circumstances. Determination of whether a conflict of interest or bias exists in a particular instance will be a matter of judgment involving all the material facts of the situation. In addition, any person designated by Caltech to facilitate any of the resolution processes set out below (e.g., Title IX Coordinator, investigators, decision maker, administrators who determine sanctions and remedies, administrator hearing an appeal of an outcome of an investigation process) will receive training that is trauma-informed and comprehensive and that includes information appropriate to their respective roles. The Administrative Resolution process and the Remedy-Based Resolution process are available only at the discretion of the Title IX Coordinator under circumstances they deem appropriate. Civil law remedies may also be available to complainants. A complainant may, on their own, choose to pursue any such remedies independent of and in addition to any of Caltech's resolution processes. Caltech does not provide legal advice about civil law remedies. General Information A. Administrative Resolution The Title IX Coordinator, with the voluntary written consent of the parties, may offer the opportunity to resolve the complaint by administrative resolution. Administrative resolution (AR) provides an opportunity for the respondent to accept responsibility for their alleged conduct and proceed to a resolution without a formal investigation. Complainants and respondents participating in this process may have an adviser of their choice accompany them when engaging in this resolution process, as set forth above in Section III. If the AR option is agreed to by a complainant, the Title IX Coordinator will meet with the respondent to review the allegations. The Title IX Coordinator will provide the respondent with information on the respondent's rights and options under the policy and these procedures. The Title IX Coordinator will also provide the respondent with written materials outlining information on campus support resources and services, including their contact information and days and hours of availability. The Title IX Coordinator will offer the respondent the opportunity to resolve the complaint by AR by accepting responsibility for the alleged conduct. It is the respondent's option and decision whether to do so. If the respondent elects to acknowledge that the alleged conduct occurred and takes responsibility for the alleged conduct, the respondent will sign a written acknowledgement, and the matter will be referred to the appropriate decision maker for a decision concerning sanctions and remedies that may be appropriate. Generally, for purposes of determining sanctions in connection with an AR, the decision maker shall be determined based upon the respondent's affiliation (the vice provost of research or administration for faculty, the assistant vice president for human resources for postdoctoral scholars and campus staff, or the deputy director for Human Resources at JPL for JPL employees). In the case of student respondents, the appropriate dean will serve as the decision maker. In determining sanctions and remedies, decision makers will consult with the Title IX Coordinator and may consult with any other individual they deem appropriate. The parties will both be notified simultaneously in writing of the resolution, including any sanctions and remedies. Within ten (10) calendar days of receiving this letter, either party may appeal in writing as outlined below in Section D, 11. An AR process will be concluded within a reasonably prompt time frame after the complaint has been made, generally forty-five (45) calendar days. The Title IX Coordinator will keep the parties informed of the status of the process. The Title IX Coordinator may delay the process temporarily or extend the time frame for good cause, providing written notice to the parties of any delays or extensions and the reasons therefor. Good cause may include but is not limited to the absence of a party or a party's adviser; the need for language assistance or accommodation of disabilities; the breadth and scope of the allegations and number of parties; and office closures. If a resolution is not reached under this process within a reasonable amount of time, or if the Title IX Coordinator determines that one or 101 Institute Policies 102 both parties are not participating in good faith or a timely or appropriate manner in the process, the Title IX Coordinator may terminate the process, and the complainant may pursue the other resolution options. An AR is the final resolution of the allegations contained therein. B. Remedy-Based Resolution The RBR is not available to resolve allegations made by a student of Title IX-covered prohibited conduct set out in Section 15.0 of the policy against a Caltech employee. A remedy-based resolution (RBR) is a mutual agreement entered into among Caltech and the parties to a formal complaint. The Title IX Coordinator determines whether an RBR is an appropriate option for resolving the allegations at issue. Factors the Title IX Coordinator may consider in determining the appropriateness of an RBR include those set forth in Section VIIl., paragraph 3 of this document. Depending on the allegations and circumstances, a respondent agrees to undertake, or all parties agree to undertake, certain social, academic, and/or administrative steps, on a certain timeline, as a means of resolving a complaint of prohibited conduct without an investigation and a finding regarding responsibility or discipline against a respondent. All parties must voluntarily agree to all the terms of the RBR as the complete and final resolution of the formal complaints). In other words, if an agreement is reached, the complainant cannot subsequently file a formal complaint for an investigation regarding the same alleged conduct, unless a respondent does not fulfill their agreed upon commitments under the RBR as determined by the Title IX Coordinator. Complainants and respondents participating in this process may have an adviser of their choice accompany them when engaging in this resolution process, as set forth above in Section Ill. Key aspects of an RBR include that it: • is a voluntary process when available to resolve allegations; unlike an investigation process, there are no circumstances (e.g., safety of a minor, safety of a party or the community) under which Caltech can undertake this process against the wishes of a party; • focuses on non-disciplinary remedies to the concerns underlying the alleged prohibited conduct. For example, under an RBR, a respondent can agree to undertake a counseling and/or education program to address behavioral issues. In an investigation process, a decision maker cannot compel counseling as part of the sanction; • provides a measure of control to the complainant in crafting measures and remedies undertaken by the respondent, allowing the complainant to focus on remedying specific social, academic, or administrative concerns; • leaves open to the parties the alternative option of pursuing an investigation at any time during the negotiation process, or if the parties ultimately cannot come to a mutually acceptable agreement or if a party fails to comply with any or all of their commitments under an executed RBR as determined by the Title General Information IX Coordinator; • provides both parties a final resolution of the complaint, if an agreement is reached; and • does not involve an adjudication of the allegations and a potential finding of responsibility against the respondent. In cases in which the Title IX Coordinator determines an RBR may be appropriate, the Title IX Coordinator will discuss with a complainant potential elements of an RBR pertinent to their concerns and allegations to help them determine whether an RBR is an option they wish to pursue. If all parties to a formal complaint are agreeable to pursuing a resolution through the RBR process and provide voluntary written consent to engage in the RBR process, the Title IX Coordinator will work with the parties to negotiate and craft the agreement. The parties do not engage directly with one another. The Title IX Coordinator, with the consent of the parties, may seek the assistance of academic and administrative leadership, as appropriate, to make possible and implement elements of the agreement. There are certain situations, however, where the Title IX Coordinator may determine that the parties' ability to discuss and reach a resolution of the concerns requires intervention and facilitation by a third-party mediator outside the Caltech community. If the parties agree to work with a mediator, the Title IX Coordinator will make the arrangements. The decision to use a third-party mediator is within the sole discretion of the Title IX Coordinator. Potential elements of an RBR agreement include, but are not limited to, counseling or substance abuse treatment for a respondent; training for a respondent provided by the Title IX Coordinator and/or other resources; and other supportive measures, as described above in Section VI. An RBR process culminating in a signed agreement will be concluded within a reasonably prompt time frame after the complaint has been made, generally forty-five (45) calendar days. The Title IX Coordinator will keep the parties informed of the status of the process. The Title IX Coordinator may delay the process temporarily or extend the time frame for good cause, providing written notice to the parties of any delays or extensions and the reasons therefor. Good cause may include but is not limited to the absence of a party or a party's adviser; the need for language assistance or accommodation of disabilities; the number of parties; and office closures. If a resolution is not reached under this process within a reasonable amount of time, or if the Title IX Coordinator determines that one or both parties are not participating in good faith or a timely or appropriate manner in the process, the Title IX Coordinator may terminate the process, and the complainant may pursue the other resolution options. A remedy-based resolution is the final resolution of the allegations it addresses, unless a party fails to carry out their commitments under the agreement, as determined by the Title IX Coordinator. 103 Institute Policies 104 C. Facilitation of Administrative Resolution or Remedy-Based Resolution During Investigation Process At any time following the filing of a formal complaint, including during an investigation process, prior to reaching a final determination regarding responsibility, inclusive of any appeal process, the Title IX Coordinator may facilitate an administrative resolution (AR) or a remedy-based resolution (RBR), if determined to be appropriate, provided that the Title IX Coordinator: Provides to the parties written notice disclosing the allegations, the requirements, and consequences of the AR or RBR process, including that: (a) completing either resolution precludes the parties from initiating or resuming a formal complaint arising from the same allegations; (b) at any time prior to completing the AR or RBR process, either party has the right to withdraw and initiate or resume the investigation process; and (c) notice of records that will be maintained or could be shared and with whom. 2. Obtains the parties' voluntary written consent to the AR or RBR process. D. Investigation Process 1. Introduction This option provides both parties with an investigation and adjudication of the allegations. The investigation and adjudication of alleged prohibited conduct under this section is not an adversarial process between the complainant, the respondent and the witnesses, but rather a process by which Caltech complies with its obligations under existing law. The complainant does not have the burden to prove, nor does the respondent have the burden to disprove, the allegations of prohibited conduct. If the decision maker determines that a preponderance of the evidence substantiates alleged prohibited conduct and a violation of the Sex- and Gender-Based Misconduct Policy, sanctions, remedies, or systemic remedies, as appropriate, will be imposed. The decisions made by the decision maker, subject to the resolution of any appeal, represent the final resolution of the formal complaint, whether or not a respondent is found responsible. Caltech's investigation will occur independently from any legal/criminal proceedings that may take place. Caltech may defer fact gathering for an appropriate time during a criminal investigation. The Title IX Coordinator will assign appropriate investigators) to carry out the investigation. The investigator(s) must be impartial and free of any conflict of interest. Generally, for complaints involving students, staff, or faculty, the Title IX Coordinator will refer the investigation to the lead investigator and appropriate deputy Title IX Coordinator. The Title IX Coordinator may appoint different investigators). All participants in an investigation will receive a fair and impartial process and be treated with dignity, care, and respect. Caltech's policy and investigation procedures are intended to ensure that individuals reported for prohibited conduct are not prejudged and are General Information provided with adequate notice and an opportunity to be heard regarding the allegations made against them. Respondents are presumed not responsible for the alleged conduct until a determination regarding responsibility is made at the conclusion of the investigation process. The purpose of the investigation is to gather the evidence relating to the complaint, and decisions are based on an objective evaluation of all relevant evidence, including both inculpatory and exculpatory evidence. Evidence may include statements from the parties and witnesses; documents relating to the complaint, such as texts, photographs, and emails; and physical evidence, such as clothing, rape kit evidence, and weapons. Credibility determinations may not be based on a person's status as a complainant, respondent, or witness. The investigation will be trauma-informed and impartial. Those involved in questioning parties and witnesses —namely, the Title IX Coordinator and Title IX deputies, the investigators and the decision maker-will receive training in conducting fair and trauma-informed investigations and hearings. The investigation will be treated as private to the extent possible. Caltech administrators will be informed on a need-to-know basis. Caltech will make reasonable and appropriate efforts to preserve the privacy of the parties and witnesses, and protect the confidentiality of information. With the exception of the hearing portion of the investigation process, as set out below, no meetings or conversations that take place as part of the investigation process may be recorded by anyone. Investigation files, including the recording of the hearing, will be maintained by the Equity and Title IX Office. Caltech does not tolerate retaliation and will take steps to prevent retaliation and strong responsive action if it occurs. All participants, including complainants, respondents, and witnesses, are protected against retaliation and will be advised to notify Caltech immediately if retaliation occurs. Any new allegations that arise during the course of the investigation that could subject either party to new or additional sanctions shall be subject to the notice requirements set out above in Sections V (Initial Title IX Assessment) and XI (Notice of Allegations). 2. Limitations on Questioning The investigators and decision maker will not ask parties or witnesses questions that are repetitive, irrelevant, or harassing. Consistent with federal and state law, the investigators and the decision maker will not ask questions or seek evidence of a complainant's or respondent's prior or subsequent sexual conduct with anyone other than the respondent, except to the extent such questions and/or evidence are used to determine whether someone other than the respondent committed the conduct alleged by the complainant. Furthermore, evidence of a prior consensual sexual, romantic, or intimate relationship between the complainant and respondent does not by itself imply consent or preclude a finding of prohibited conduct. The investigators and decision maker shall not consider the existence of a 105 Institute Policies 106 dating relationship or prior or subsequent consensual sexual relations between the parties unless the evidence is relevant to how the parties communicated consent in prior or subsequent consensual sexual relations. Where the investigators or decision maker allow consideration of evidence about a dating relationship or prior or subsequent consensual sexual relations between the parties, the mere fact that the parties engaged in other consensual sexual relations with one another is never sufficient, by itself, to establish that the conduct in question was consensual. Before allowing the consideration of any evidence described in this section, the investigators or decision maker shall provide a written explanation to the parties as to why consideration of the evidence meets the requirements for consideration. The investigation, at any stage, will not require, allow, rely upon, or use questions or evidence that constitute or seek the disclosure of information protected under a legally recognized privilege (e.g., attorney-client, doctor-patient, clergy-penitent), unless the person holding such privilege has waived the privilege. Questions that seek information about any party's medical, psychological, and similar records are not permitted unless the party has given written consent. 3. Amnesty Concerning Student Policy Violations: Complainants and Witnesses The investigators will investigate any allegations that alcohol or drugs were involved in the incident. A student who participates as a complainant or witness in an investigation of sexual assault, dating violence, domestic violence, or stalking will not be subject to disciplinary sanctions for a violation of Caltech's student conduct policies at or near the time of the incident, including but not limited to the Substance Abuse Policy, unless Caltech determines that the violation was egregious, including but not limited to, an action that places the health or safety of any other person at risk or involves conduct that violates Caltech's policies prohibiting discrimination, or other serious misconduct like plagiarism, cheating, research misconduct, or other forms of academic dishonesty. Whether a student's violation of the Student Health and Hygiene Policies and other COVID-19-related measures warrants amnesty will be determined on a case-by-case basis by the Title IX Coordinator. However, absent conduct showing a deliberate and reckless disregard for the health of others - for example, by hiding one's own known infected status and exposing others - a student who participates as a complainant or witness in an investigation of sexual assault, dating violence, domestic violence, or stalking will not be subject to disciplinary sanctions for a violation of such policies and measures. General Information 4. Standard of Evidence All decisions made in the course of this investigation process will utilize the preponderance of evidence standard. A preponderance of evidence means that it is more likely than not that the alleged prohibited conduct occurred. Stated another way, it means that the likelihood the alleged prohibited conduct occurred is any amount over 50%. The decision maker will make a decision on the disputed facts and also decide whether the evidence makes it more likely than not that the alleged prohibited conduct occurred based on the evidence available at the time of the decision. When the decision maker is presented with two different but plausible versions of alleged prohibited conduct, credibility determinations may affect the outcome. 5. Identity of the Decision Maker The Title IX Coordinator shall have the discretion to determine which appropriately trained individual will serve as the decision maker in the investigation process. As set forth below, the decision maker conducts any hearing that takes place under these procedures. The parties will be notified of the identity of the decision maker before the hearing as well as the process for objecting to the identity of the decision maker on the basis of a conflict of interest or bias. 6. Determination of Sanctions, Remedies, and Systemic Remedies At the conclusion of the investigation process, if there is a finding of responsibility, the appropriate administrator will determine the appropriate sanctions, remedies, and systemic remedies. Generally, the appropriate administrator shall be determined based upon the respondent's affiliation (the vice provost for research or administration for faculty, the assistant vice president for human resources for postdoctoral scholars and campus staff, the deputy director for human resources at JPL for JPL employees, and the appropriate dean for student respondents). In determining sanctions, remedies, and systemic remedies, these administrators will consult with the Title IX Coordinator and may consult with any other individual they deem appropriate. 7. Timeline Complaints will be investigated and resolved within a reasonably prompt time frame after the complaint has been made, generally 120 calendar days. The Title IX Coordinator will provide the parties written updates of the status of the investigation every thirty (30) days, including the date by which the parties shall be notified of the outcome of the investigation and the deadlines and process for parties to appeal. The Title IX Coordinator may delay the investigation process temporarily or extend the time frame for good cause, providing prompt written notice to the parties of any delays or extensions and the reasons therefor. Good cause may include but is not limited to the absence of a party, a party's adviser, or a witness; concurrent law enforcement activity; the need for language assistance or accommodation of disabilities; the breadth and scope of the allegations, in terms of 107 Institute Policies 108 content and date, the number of potential witnesses, and the amount of available, relevant documentary evidence; the need to conduct a thorough, fair and accurate investigation; and office closures. The Title IX Coordinator shall not unreasonably deny a party's request for an extension of a deadline related to a complaint during periods of examinations or school closures. 8. Procedural Steps for Investigation 1) The Title IX Coordinator initiates the investigation process with a notification sent to both parties. This initial notification will identify the assigned investigators) and will notify the parties of their right to and process for objecting to either of the investigators) or to the Title IX Coordinator on the basis of conflict of interest or bias. The notification will include the estimated date by which the parties will be notified of the outcome of any investigation. 2) The complainant and respondent may have an adviser of their choice, in accordance and subject to the requirements set out above in Section Ill of these procedures and the Adviser Policy and Confidentiality Agreement. 3) The Title IX Coordinator or associate vice president of human resources, as appropriate, will consider any objections by the parties on the basis of conflict of interest or bias and determine the Title IX Coordinator and investigator(s) for the process. 4) After a reasonable amount of time to review the notice of allegations and applicable policies and procedures, the parties will be given equal opportunity to meet with the investigators). In those meetings, the investigators) will seek and gather evidence about the allegations, including any documents or physical evidence, as well as the identification and location of witnesses. 5) Throughout the process, the parties may suggest witnesses and documents to the investigators) as well as questions for the investigator(s) to ask the other party and any witnesses. The investigators) will determine whether the suggestions are relevant and appropriate. Caltech asks the parties to keep the investigation private but cannot and will not prohibit the parties from discussing the investigation with others in connection with identifying evidence for the investigators) to gather. The parties may not, however, engage in coercion, pressure, undue influence, or retaliation with respect to potential witnesses or other parties in the course of identifying evidence for the investigator(s). The parties may seek guidance from the Title IX Coordinator and the investigator(s) on avoiding these concerns. Communications between parties and witnesses deemed to have resulted from coercion, pressure, undue influence, or retaliation may be discounted altogether by the decision maker or may be considered by the decision maker in making credibility determinations and weighing evidence deemed subject to the undue influence. 6) The investigators) will interview relevant witnesses and gather other evidence related to the allegations, if any. Witnesses may General Information also submit documents or written statements to the investigators), to supplement their in-person or video interviews. 7) In addition to providing information orally during meetings with the investigators), the parties may submit written statements and evidence to the investigators) that document their experiences. Written statements, however, may not wholly supplant live face-to-face or video interviews with the investigators). Live face-to-face or video meetings and questioning are important to enable the investigators to conduct a fair, thorough, and efficient investigation. While Caltech cannot compel any party or witness, to meet with the investigators), appropriate due process may require Caltech to discount any written statements, and even information provided orally, that the investigators cannot inquire about in an in-person or video meeting. 8) The investigators) will prepare a draft investigation report identifying the facts disputed by the parties for each allegation, as well as summarizing and identifying the relevant, related evidence gathered, including facts relevant to the credibility of parties or witnesses or items of evidence. The investigators will also provide appendices containing the evidence gathered. The complainant and respondent will be given equal opportunity to review and respond to the investigation report. The report will also be provided to the parties' advisers. All those receiving access to the report will be required to sign a non-disclosure agreement to protect the confidentiality of the material. The non-disclosure agreement will not prohibit the parties from discussing the investigation with others in connection with identifying additional evidence for the investigators) to gather. Failure to comply with the nondisclosure agreement on the part of a party or their adviser may subject the appropriate party to discipline. If an adviser violates the nondisclosure agreement it will be grounds for excluding the adviser from further participation in the proceedings. The parties will have at least ten (10) calendar days to submit a written response to the report. The investigators will determine whether the parties' responses require any follow-up investigatory action or an opportunity for the other party to respond. 9) The investigators) will finalize the investigation report. This finalized investigation report will be provided to the parties and their advisers, and the decision maker at least thirty (30) calendar days before any hearing. 10) Where the investigation addresses allegations that only fall within the policy Section 16.0, setting out conduct prohibited by the California Education Code, Caltech will determine whether a hearing is necessary to determine whether that alleged prohibited conduct more likely than not occurred. In making this decision, Caltech will consider whether the parties elected to participate in the investigation, as well as the fact that each party had the opportunity to suggest questions for other parties, or witnesses, or both, during the investigation. If Caltech determines a hearing is necessary, that hearing will not involve any cross-examination 109 Institute Policies 110 of any party or witness conducted directly by a party or a party's adviser. 11) Prior to any hearing, the parties will be notified of the identity of the decision maker and will be given an opportunity to object to that individual on the basis of a conflict of interest or bias. 12) At any hearing conducted under the investigation process, the decision maker will meet face-to-face, in person or via video, separately, with the parties, and others whom the decision maker deems appropriate, prior to deciding how to resolve the disputed facts, make credibility determinations, and determine whether the allegations and any policy violations are substantiated by a preponderance of the evidence. Any hearing is private and closed to the public. Only the decision maker, the parties and their advisers, witnesses, appropriate administrators, and others determined by Caltech to be necessary to the hearing may attend. The decision-maker will determine an appropriate and reasonable scope and time frame for the hearing, as well as logistical processes for the hearing, such as for making objections and submitting questions. 13) The hearing will be conducted with the appropriate technology to allow the parties to virtually observe each other's meeting, and any witness meetings, with the decision maker while maintaining their physical separation. Parties or witnesses may request to appear by video from a remote location. Caltech will grant the request of any party that the entire hearing, including cross-examination, be held virtually. In making this request, the party does not need to provide a reason. In the absence of such a request. the Title IX Coordinator has the discretion to allow any party or witness to appear at the hearing virtually, with technology enabling participants simultaneously to see and hear each other, as appropriate. Any requests for disability accommodations should be made to the Title IX Coordinator and Caltech's Accessibility Services Specialist. 14) All of the evidence that was made available previously in the investigation report will be made available at the hearing to give each party equal opportunity to refer to such evidence during the hearing. 15) Before and during the hearing, the parties may submit written questions for the lead investigator and decision maker to ask the other party and any witnesses with whom the decision maker is meeting (indirect cross-examination). The parties can submit written questions during the hearing through the appropriate technology while maintaining their physical separation. The decision maker will facilitate the questioning and may consult with the lead investigator. The decision maker will have the discretion to exclude any question(s) that they determine inappropriate. At the hearing, the other party shall have the opportunity to note an objection in writing to a question posed. Neither the decision maker nor Caltech is obligated to respond to the objection but may consider it and must include it in the record. The decision maker shall have the authority and General Information obligation to discard or rephrase any question that the decision maker deems to be repetitive, irrelevant or harassing. In making these determinations, the decision maker is not bound by, but may take guidance from, the formal rules of evidence. 16) The parties may not introduce evidence, including witness testimony, at the hearing that the party did not identify during the investigation and that was available at the time of the investigation. However, the decision maker has the discretion to accept for good cause, or to exclude, such new evidence offered at the hearing. 17) In addition, consistent with guidance issued by the Department of this paragraph (q) apply only at hearings adjudicating allegations of prohibited conducted covered under Title IX (policy Section 15.0) and occurring, in whole or in part, on or after August 14, 2020: (i) each party's adviser (but not the parties themselves) may directly and orally ask the other party and any witnesses all relevant questions and follow-up questions, including those challenging credibility (direct cross-examination); (i) before a party or witness answers an adviser's direct question, the decision maker must first determine whether the question is relevant and explain any decision to exclude a question as not relevant or otherwise inappropriate; and (iii) for the purpose of the hearing only, if a party does not have an adviser, Caltech will provide without fee or charge to that party an adviser of Caltech's choice who may be, but is not required to be, an attorney, to conduct direct cross-examination on behalf of that party. In conducting direct cross-examination of a party or witness, the adviser of a party may ask only those questions drafted by the party whom they are advising. The adviser may not ask questions their party has not drafted. The adviser, moreover, must maintain a calm and respectful tone throughout the direct cross-examination. An adviser may not make objections, statements, or arguments during the cross-examination or otherwise during the hearing. The decision maker may disqualify an adviser who does not follow these rules. 18) The decision maker will comply, and ensure others when allowed to ask questions comply, throughout the hearing with Section XIII(D)(2) (Limitations on Questioning) of these procedures. 19) Caltech cannot compel either party, or any witness, to meet with the decision maker at the hearing. However, if a party or witness does not attend the hearing or, when required, refuses to submit to direct cross-examination at the hearing, the decision maker will not rely on any statement of that party or witness in reaching a determination regarding the respondent's responsibility. Police reports, medical reports and other documents and records may not be relied upon to the extent they contain statements of a party or witness who has not submitted to cross-examination. However, the term "statements" does not include, for example, evidence such as videos or photographs of the underlying 111 Institute Policies 112 incident. The decision maker may consider texts or emails that in themselves constitute the alleged sexual harassment. The decision maker will decide what evidence may be relied upon with respect to this paragraph (t). The decision maker cannot draw an inference about the determination regarding responsibility based solely on a party's or witness's absence from the hearing or refusal to answer direct cross-examination questions. This means, for example, that the decision maker may not make any decisions about a party's credibility based on their decision not to participate in a hearing or submit to cross-examination. The decision maker may re-evaluate the decision ming or submit Yoased on thei relevance of any question a party or witness refuses to answer after the hearing has concluded. If a party or witness submits to cross-examination by a party's adviser but does not answer a question posed by the decision maker, the decision maker may still rely on that person's statements. The decision maker may not draw any inference about the party's credibility in making the responsibility determination based solely on a party's refusal to answer questions posed by the decision maker. 20) Caltech will create an audio or audio-visual recording, or transcript, only of the hearing and make it available to the parties upon request for their inspection and review. No party, adviser, or witness is permitted to make independent recordings of the hearing or any other meeting or conversation that takes place under the investigation process. 21) The decision maker will resolve the disputed facts, make credibility determinations, and decide whether the allegations and any policy violations are substantiated by a preponderance of the evidence. In making these decisions, the decision maker will consider the final investigation report and appendices of evidence, the parties' responses to the draft investigation report, the information gathered in the hearing, and the decision maker's credibility assessments of those interviewed at the hearing, as appropriate. The potential conclusions the decision maker can reach include but are not limited to: a violation of Caltech's Sex-and Gender-Based Misconduct Policy occurred; inappropriate behavior but no violation occurred; the complaint was not supported by the evidence; the complaint was brought without a reasonable good-faith basis. After making these decisions, the decision maker will meet with the appropriate administrator who will determine any sanctions, remedies, and systemic remedies, in order to brief them on the process and factual findings and conclusions. That administrator will be identified and will determine any sanctions, remedies, and systemic remedies, if appropriate, in accordance with Section XIIID) (5)(Identity of the Decision Maker), (6)(Determination of Sanctions, Remedies, and Systemic Remedies), and (9)(Potential Sanction, Remedies, and Systemic Remedies) of these General Information procedures. The decision maker will notify the parties simultaneously of all of these determinations in writing. The letter will include: a description of the procedural steps taken from the receipt of the formal complaint through the determination of responsibility, including any notifications to the parties, interviews with parties and witnesses, site visits, methods used to gather other evidence, and hearings held; c) findings of fact supporting the determination; d) conclusions regarding the application of the Sex- and Gender-Based Misconduct Policy and any other applicable Caltech policy to the facts; e) a statement, and rationale for, the result as to each allegation, including a determination regarding responsibility determined by the appropriate administrator; and procedures and permissible bases for the complainant and respondent to appeal. 22) The determinations regarding responsibility and sanctions, remedies, and systemic remedies become final either on the date that the parties are provided the result of any appeal, or if an appeal is not filed, the date on which an appeal would no longer be considered timely. 23) The Title IX Coordinator will be informed of the outcome of the investigation and any appeal in order to carry out their responsibilities to consult on and coordinate implementation of any sanctions, remedies, and systemic remedies, monitor outcomes, identify and address areas of needed education and training presented by the case, and assess and address effects on the campus climate. 24) Exceptions to or modification of these procedures can be made at any time by the Title IX Coordinator, provost, deans or associate deans, associate vice president for human resources, or director for human resources at JPL in order to ensure these procedures promote fairness to both parties and compliance with the law. 9. Potential Sanctions, Remedies, and Systemic Remedies If a violation of Caltech's Sex- and Gender-Based Misconduct Policy has occurred, appropriate sanctions, remedies, and systemic remedies, as appropriate, will be imposed. The appropriate administrator may impose any one or more of the following: Sanctions • Verbal warning; • Training; • Mandatory coaching; • Mandatory substance abuse treatment; • A formal written warning placed in the respondent's file; 113 Institute Policies 114 • Exclusion from participation in certain activities for a specified period of time; • Temporary or permanent exclusion from campus; • Suspension of the right to accept new graduate students or postdoctoral scholars; • Transfer of advisees; • Removal from positions of administrative responsibility; • Suspension from positions requiring supervision or interaction with students or other members of the Caltech community; • Restricted access to Caltech premises; • Restricted access to Caltech's educational programs or activities; • Removal from Caltech housing; • Removal from a supervisory position; • Involuntary leave of absence/suspension; • Expulsion; • Termination of employment; • Permanent separation from the Institute; • Revocation of admission; • Delay or revocation of degree. Remedies • Access to counseling services and assistance in setting up initial appointment, both on and off campus; • Imposition of "No Contact Letter;" where a no-contact directive is issued after a finding of responsibility has been made, it shall be unilateral and apply only against the party found responsible; • Rescheduling of exams and assignments, and reassignment of grading or other evaluative responsibilities (in conjunction with appropriate faculty and deans as necessary); • Providing alternative course completion options (with the agreement of the appropriate faculty); • Change in class schedule, including the ability to take an "incomplete," drop a course without penalty, or transfer sections (with the agreement of the appropriate faculty); • Change in work schedule or job assignment; • Change in on-campus housing, when feasible; • Arranging to dissolve a housing contract and prorating a refund in accordance with campus housing policies; • Assistance from Caltech support staff in completing housing relocation; • Limiting an individual or organization's access to certain Caltech facilities or activities pending resolution of the matter; • Voluntary leave of absence; • Providing an escort to ensure safe movement between classes and activities; • Providing medical services; • Providing academic support services, such as tutoring; • Any other remedy that can be tailored to the involved individuals to reasonably achieve the goals of this policy. General Information Systemic Remedies • Institute-wide, Division-wide, and/or Option-wide, or other team-based communication or outreach effort and training, as appropriate • Addition of information to Equity and Title IX Office website, or other Institute website, as appropriate • Conduct of appropriate climate survey to gather information pertinent to preventative outreach efforts• Institute-wide, division-wide, and/or option-wide, or other team-based 115 other Institute website, as appropriate; • Conduct of appropriate climate survey to gather information pertinent to preventative outreach efforts. If the respondent was found not to have violated Caltech's Sex- and Gender-Based Misconduct Policy, but the investigation concluded that they committed some other wrongful or improper act, appropriate corrective action will be taken. Effective corrective action may also require remedies for a complainant and/or systemic remedies for the broader Caltech community. Caltech will take appropriate measures to prevent the reoccurrence of any prohibited conduct, and to correct and prevent any discriminatory or retaliatory effects, as appropriate. In determining sanctions, remedies, and systemic remedies, as appropriate, the administrator will consult with the Title IX Coordinator and other persons they deem appropriate, to enable Caltech to take steps to prevent recurrence of any harassment and to correct its discriminatory effects on the complainant and, if appropriate, others. NOTE: The Institute may undertake remedies and systemic remedies, as appropriate, to safeguard a complainant's access to education, at any time. The complainant's engagement in a resolution process is not a prerequisite for such Institute action. Moreover, Caltech shall consider and respond to requests for accommodations relating to prior incidents of sexual harassment that could contribute to a hostile educational environment or otherwise interfere with a student's access to education where both individuals are, at the time of the request, subject to Caltech's policies. 10. Disclosure of Outcomes Outcomes of disciplinary proceedings may be disclosed consistent with applicable law, including FERPA, Title IX, and the Clery Act. Upon request, Caltech will disclose the outcomes of a disciplinary proceeding against a student who is the alleged perpetrator of any crime of sexual violence to the alleged victim. Outcomes of the investigation process will be disclosed on a need-to-know basis, as determined by the Title IX Coordinator, in order to effect sanctions and/or other remedies and systemic remedies. Institute Policies 116 11. Appeal Appeals may be submitted by either party. They must be in writing and submitted within ten (10) calendar days of notification of the decision to the appropriate administrator (the provost for faculty, the associate vice president for human resources for postdoctoral scholars and campus staff, the vice president of student affairs for students, or, the director for human resources at JPL for JPL employee respondents). In assessing appeals, these administrators may consult with any individual they deem appropriate. The recipient of the appeal will notify the Title IX Coordinator and any other party in writing when an appeal Appeals of decisions resulting from the investigation process are limited to one or more of the following grounds: a procedural irregularity that affected the outcome of the matter; new evidence (including a new witness) that was not reasonably available at the time the determination regarding responsibility was made and that could affect the outcome of the matter; the Title IX Coordinator, investigators), decision makers), or administrator who determined and imposed any sanctions or remedies had a conflict of interest or bias for or against complainants or respondents generally or the individual complainant or respondent that affected the outcome of the matter; the sanctions or remedies are substantially disproportionate to the conduct for which the respondent was found responsible. If a party submits an appeal, the other party will have the opportunity to submit a written response to the appeal within ten (10) calendar days of the filing of the appeal. The parties simultaneously will be informed, in writing, of the outcome of the appeal. The appeal decision letter will state the rationale for the result. Appeal decisions are final. XIV. Further Complaints If the corrective action does not end the prohibited conduct, the complainant should immediately notify at campus the Title IX Coordinator, or a deputy Title IX Coordinator, the provost or a division chair, dean or associate dean, Employee and Organizational Development director; or at JPL, the Deputy Title IX Coordinator. In such cases, the complainant has the right to file another formal complaint based on new prohibited conduct. Related Policies and Procedures • Sex- and Gender-Based Misconduct Policy • Nondiscrimination and Equal Employment Opportunity Policy • Unlawful Harassment Policy • Procedures for Complaints of Unlawful Discrimination, Harassment and Retaliation • Violence Prevention Policy General Information SUBSTANCE ABUSE 1.0 Policy Caltech is committed to providing a safe, healthy, and productive work and academic environment for all members of the Caltech community. Consistent with the Drug-Free Workplace Act of 1988 and the Drug-Free Schools and Communities Act Amendments of 1989, it is Caltech's policy to maintain a work and academic environment free from drug and alcohol abuse. Faculty, staff, postdoctoral scholars, students, visitors, volunteers, and contractors performing work on Caltech's premises, including at the Jet Propulsion Laboratory ("JPL"), are required to comply with this policy. 2.0 Scope 2.1 Prohibited Conduct The unlawful use, manufacture, distribution, cultivation, dispensation, possession, sale, purchase of, or offer to sell or purchase controlled substances or alcohol on the Caltech campus or its off-site locations, including JPL, or as any part of its activities, is prohibited. Controlled substances include, but are not limited to, amphetamines, cocaine, marijuana, opiates, phencyclidine (PCP) and their metabolites. Despite recent changes to California law, marijuana still is a controlled substance under federal law, and therefore the use, manufacture, distribution, cultivation, dispensation, possession, sale, purchase of or offer to sell or purchase marijuana on the Caltech campus or its off-site locations, including JPL, or as any part of its activities, continues to be prohibited. The recreational use of nitrous oxide is also prohibited under this policy. In addition, every employee is prohibited from being under the influence of controlled substances, alcohol, or any substance that may impair the employee's ability to perform their job duties safely or productively, or that may otherwise impair their senses, coordination, or judgment while on duty. Any employee reporting to work (or otherwise at work) under the influence of, or having present in their body, any prescribed drug, alcohol, or other substances or medication that may adversely affect the employee's ability to work in a safe, productive, or efficient manner, must advise the Disability and Leave Unit. Caltech may require an employee to submit to drug and alcohol testing consistent with Caltech policy and applicable federal and state law. Testing procedures that apply to JPL employees are available on the JPL Human Resources website. 2.2 Requirements for Employees and Students As a condition of continued enrollment, every student is required to comply with this policy. As a condition of employment, all Caltech employees (this includes faculty, staff, postdoctoral scholars, and student employees), regardless of their location, are required to comply with this policy. A Caltech employee who violates this policy will be subject to disciplinary action up to and including termination of employment. A violation of this policy is likely to result in termination, 117 Institute Policies 118 even for a first offense. Similarly, all students, not just student employees, should understand that disciplinary action including involuntary leave or expulsion from Caltech may be invoked for violation of this policy and that intoxication is never an excuse for misconduct. Caltech may contact a student's parents when a student under 21 violates this policy. If a student's behavior with respect to alcohol and drugs presents a danger to themselves or others, Caltech may inform the parents. In addition, pursuant to federal law, a student's eligibility for federal financial aid may be suspended if the student is convicted, under federal or state law, of any offense involving the possession or sale of illegal drugs. A faculty, staff, postdoctoral scholar, or student who is convicted (including a plea of nolo contendere [no contest]) of a criminal drug statute violation occurring in the workplace or on Caltech property must notify Caltech in writing within five (5) calendar days after the conviction. Campus employees should inform the assistant vice president of human resources, and students should inform their dean. JPL employees should inform the manager of employee relations. 2.3 Third Party Requirements Persons who are not employees of Caltech but who perform work at Caltech for its benefit (such as contractors and their employees, temporary employees provided by agencies, volunteers, and visitors engaged in joint projects at Caltech, etc.), are required to comply with this policy. Violation of this policy is likely to result in being barred from the workplace even for a first offense. 3.0 Health Risks The use of any mind- or mood-altering substance, including alcohol, can lead to psychological dependence, which is defined as a need or craving for the substance and feelings of restlessness, tension, or anxiety when the substance is not used. In addition, with many substances, use can lead to physical tolerance, characterized by the need for increasing amounts of the substance to achieve the same effect, and/or physical dependence, characterized by the onset of unpleasant or painful physiological symptoms when the substance is no longer being used. As tolerance and psychological or physical dependence develop, judgment becomes impaired, and the individual often does not realize they are losing control over the use of the substance and that they need help. It is impossible to predict accurately how an individual will react to a specific drug or to alcohol because effects vary depending on the person, environmental variables, the dosage and potency of the substance, the method of taking the substance, the frequency of use, and whether the substance is taken in conjunction with other substances. Illegal drugs have particularly unpredictable effects due to variability in dosage and purity. Further, the overall potency of street drugs has increased dramatically over the past two decades, making users increasingly susceptible to negative effects. General Information Alcohol acts as a depressant to the central nervous system and can cause serious short- and long-term damage. Short-term effects include nausea, vomiting, and ulcers; more chronic abuse can lead to brain, liver, kidney, and heart damage, and even to eventual death. Ingesting a large amount of alcohol at one time can lead to alcohol poisoning, coma, and death. Drugs such as LSD, amphetamines, marijuana, and alcohol alter emotion, cognition, perception, physiology, and behavior in a variety of ways. Health risks include but are not limited to depression, apathy, hallucinations, paranoia, and impaired judgment, and all substances have an adverse effect on pregnancy and the fetus. When two or more substances are combined, the effect is often stronger than their additive sum. 4.0 Local, State, and Federal Legal Sanctions Local, state, and federal laws establish severe penalties for violations of drug and alcohol statutes. These sanctions, upon conviction, may range from a fine to life imprisonment. In the case of possession and distribution of illegal drugs, these sanctions could include the seizure and summary forfeiture of property, including vehicles. It is especially important to know that federal laws have established penalties for illegally distributing drugs to include life imprisonment and fines of up to $10,000,000. 4.1 Examples • Unlawful possession of a narcotic drug is punishable by imprisonment in the state prison. • The purchase, possession, or consumption of any alcoholic beverages (including beer and wine) by any person under the age of 21 is prohibited. • It is illegal to provide alcohol to a person under the age of 21. • Serving alcohol to an intoxicated person is prohibited. • Selling any alcoholic beverages, except under the authority of a California Alcoholic Beverage Control License, is prohibited. • It is a felony to induce another person to take various drugs and "intoxicating agents" with the intent of enabling oneself or the drugged person to commit a felony. The person who induced the other may be regarded as a principal in any crime committed. • Any person found in a public place to be under the influence of an intoxicating liquor or drug and unable to care for their own safety, or who is interfering with the use of a public way, is guilty of disorderly conduct, which is a misdemeanor. • It is illegal for a person to possess nitrous oxide (e.g., whippets) with the intent to inhale it for purpose of altering their mood or mental functioning. 119 Institute Policies 120 5.0 Resources for Staff, Faculty, Postdoctoral Scholars and Students Caltech recognizes drug and alcohol abuse and dependency as treatable conditions and offers faculty, staff, postdoctoral scholars, and students support programs for individuals with substance use problems. Faculty, staff, and postdoctoral scholars are encouraged to seek assistance for drug- and alcohol-related problems through the Caltech Staff and Faculty Consultation Center (SFCC) at campus and the Employee Assistance Program (EAP) at JPL. Individuals can contact the SFCC by calling (626) 395-8360, and the EAP by calling (800) 367-7474. Students are encouraged to seek assistance from the Student Wellness Services (SWS) at (626) 395-8331. In addition, faculty, staff, postdoctoral scholars, and students can seek confidential referral information through the Center for Inclusion & Diversity at (626) 395-3221. The staff of the SFCC, the EAP, and the SWS will help employees and students to identify appropriate treatment resources and will refer them to counseling, treatment, or rehabilitation programs, as appropriate. Health insurance plans provide varying amounts of coverage for substance-abuse programs to address substance abuse and rehabilitation. Individuals may contact their health providers or the Caltech Human Resources Benefits office at campus at (626) 395-6443, or JPL at (818) 354-4447, for plan details. Information obtained regarding a faculty, staff, postdoctoral scholar, or student during voluntary participation in services at the SFCC, EAP, SWS, or any related program will be treated as strictly confidential, and no information, including whether or not an individual is receiving services, will be shared with third parties, except by written consent or as required by law. 6.0 Drug and Alcohol Awareness Program Caltech has established and will maintain a drug and alcohol awareness program to educate faculty, staff, postdoctoral scholars, and students about: 1. Caltech's substance abuse policy; 2. the dangers of drugs and alcohol in a work and academic environment; 3. faculty, staff, postdoctoral scholar, and student assistance programs; and disciplinary action that may be imposed on faculty, staff, postdoctoral scholars, and students for violations of this policy. Caltech will distribute to all faculty, staff, postdoctoral scholars, and students a copy of this policy on an annual basis. General Information 7.0 Supervisor's Responsibilities If an employee is suspected of violating this policy, the employee's supervisor should consult with the director of employee and organizational development (EOD) at campus or the Employee Relations Department of the Human Resources Directorate at JPL regarding appropriate actions, which may include an investigation and discipline up to and including termination of employment. If a supervisor believes an employee's behavior raises safety concerns for the employee or others, the supervisor must take immediate action, including calling EOD on campus or the Employee Relations Department of the Human Resources Directorate at JPL, to assess and address the situation and to remove the employee from the worksite if necessary. 8.0 Caltech Sanctions Caltech will impose sanctions for violations of or failure to comply with the requirements of this policy. These sanctions will be consistently enforced, and penalties will depend on the severity of the offenses. Penalties may include employment termination, student expulsion, being permanently banned from Caltech premises, and referral to law enforcement for the most serious violations of the law and this policy (e.g., the manufacture or distribution of banned substances). Disciplinary action may be invoked entirely apart from any civil or criminal penalties that the faculty, staff, postdoctoral scholars, and students might incur. UNLAWFUL HARASSMENT 1.0 Policy It is the policy of Caltech to provide a work and academic environment free of unlawful harassment ("harassment"). Harassment is a form of misconduct that includes unwelcome physical, verbal, or nonverbal conduct that results in a person feeling intimidated, threatened, humiliated, or demeaned, and is likely to interfere with an individual's work or education, or adversely affects an individual's living conditions. Harassment in any form, based on any of the following protected characteristics and protected activities ("protected characteristics"), is unlawful and is strictly prohibited at all times, as are all forms of prohibited conduct set forth in the Sex- and Gender-Based Misconduct Policy, including sexual and gender-based harassment and sexual misconduct: • Race (includes hair texture and protective hairstyle, as well as 121 • Religion (includes religious dress and grooming practices) • Sex/gender (includes pregnancy, childbirth, breastfeeding, and/or related medical conditions) Gender identity and gender expression Sexual orientation Institute Policies 122 • Marital status • Medical condition (genetic characteristics, cancer, or a record or history of cancer) • Military or veteran status • National origin (includes language use and possession of a driver's license issued to persons unable to prove that their presence in the United States is authorized under federal law) • Ancestry (including caste) • Disability (mental and physical, including HIV/AIDS, cancer, and genetic characteristics) • Genetic information • Request for family care leave • Request for leave for a serious health condition • Request for pregnancy disability leave • Domestic violence victim status • Age (over 40) • Criminal background (Fair Chance Act) • Any other factor protected by federal, state, or local law • Association with an individual who is in one of the foregoing protected characteristics Harassment in the employment environment may include, but is not limited to, these examples: • Verbal, physical, and visual conduct that creates an intimidating, offensive, or hostile working environment, or that interferes with work performance, including conduct that denigrates or shows hostility or aversion toward an individual because of any protected characteristic • Verbal statements, such as slurs, offensive jokes, insults, epithets, name calling, or teasing • Visual or graphic images, such as offensive and/or sexually oriented posters, photographs, symbols, cartoons, drawings, computer displays, e-mails, text messages, objects, or digital and social media activity, including blogs, forums, chat rooms, social networking sites, and other social media applications • Making derogatory comments about a person's ancestry, lineage, or caste • Physical conduct, including touching, physical assaults or threats, blocking someone's path or normal movement, gestures, and leering • Other forms of intimidation, ridicule or mockery, insults, or put-downs • Interference with work performance • Unwanted sexual advances, invitations, or comments • Threats and demands to submit to sexual requests as a condition of continued employment or to avoid loss of employment benefits • Offers of employment benefits in return for sexual favors • Conversation about one's own or someone else's sex life, sex, gender, sexual orientation, gender nonconformity, and/or gender identity General Information • Inappropriate conduct or comments consistently targeted at only one gender, race, or another protected characteristic Harassment in the educational setting also includes harassment based on protected characteristics that is contrary to the pursuit of inquiry and education. The following are examples of behaviors that may constitute harassment in the educational setting: • An adviser tells a minority student not to take a certain course because the adviser says that other minority students have had difficulty in the course • A disabled individual is not included in an off-site outing because of lack of mobility • A faculty member assigns only menial tasks to a minority student worker while assigning more complex tasks to a Caucasian student worker who is at the same educational level. • A student tells racially offensive jokes within a study group session with other students • An individual is ostracized from group activities because of their national origin • A student posts racist jokes to a house email list Complaints concerning sex and gender-based discrimination and harassment and sexual misconduct are governed by the Sex- and Gender-Based Misconduct Policy. Caltech is committed to educating the community in ways to prevent harassment. Caltech requires all employees, including those responsible for directing or supervising other Caltech employees or evaluating the work of students, to regularly participate in training regarding harassment, and the prevention of harassment and other abusive conduct, consistent with federal and state legal requirements. 2.0 Scope This policy applies to all members of the Caltech community, including at JPL (students, faculty, supervisory and nonsupervisory employees, postdoctoral scholars, volunteers, interns, vendors, contractors, persons performing services under contract with Caltech, visitors, and any other individuals regularly or temporarily employed, studying, living, visiting, or otherwise participating in Caltech's employment and education programs and activities). This policy applies to conduct occurring on Institute-controlled property, at Institute-sponsored events and in Institute employment and education programs and activities regardless of location. 3.0 Reporting Complaints and Concerns Caltech's ability to remedy harassment and maintain a harassment-free environment is limited if incidents are not reported. Anyone who witnesses, experiences, or is otherwise aware of conduct that they believe to be in violation of this policy, including retaliation, is urged to immediately report it, or to request assistance and guidance, from the Equity and Title IX Office or one of the Equal Employment 123 Institute Policies 124 Opportunity coordinators listed below, at campus, or the Employee Relations Group at JPL. Reports may be made at any time. A delay should not discourage anyone from reporting harassment. Delayed reporting is better than no reporting. Reports may be made in writing or orally. Members of the Caltech community are encouraged to err on the side of reporting any conduct they think may be harassment covered under this policy, regardless of where the incident occurred or who committed it. Even if Caltech does not have jurisdiction over the incident or the perpetrator, Caltech will take reasonable action to remedy the effects of the harassment on the Caltech community and prevent any reoccurrence of the behavior. Any employee in a supervisory role, including faculty, must promptly report all alleged harassment, discrimination, gender-based misconduct, and retaliation, regardless of its alleged severity or frequency, to the Equity and Title IX Office at campus or Human Resources at JPL, which will provide guidance and advice. In addition, other employees qualifying as responsible employees under the Sex-and Gender-Based Misconduct Policy, Reporting Concerns and Complaints II, 6.2, must promptly report any instance of prohibited conduct, as defined in Prohibited Conduct III, Sections 15.0 and 16.0 to the Equity and Title IX Office or the Deputy Title IX coordinator for JPL, as appropriate. If a member of the Caltech community would like support and guidance in filing a complaint, they may contact one of the Equal Opportunity coordinators, the assistant vice president for equity and equity investigations in the Equity and Title IX Office, JPL's manager of employee relations, or the JPL section manager of talent management or Human Resources Business Partners at JPL. 4.0 Anonymous Reporting Caltech provides the following resources for anonymous reporting: Campus Hotline: (626) 395-8787 or (888) 395-8787 • Equity and Title IX Office Online Report a Concern Form (complete anonymously): Online Report Form | Equity and Title IX Office (caltech.edu) JPL Ethics Hotline: (818) 354-9999 • JPL Protective Services Division's Workplace Violence Hotline: (818) 393-2851 • For either Campus or JPL by submitting a compliance Hotline Contact Form If the reporting party wants to remain anonymous, they should not share any personally identifying information. If the reporting party does share such information, the Equity and Title IX Office will contact the reporting party with information about support resources and reporting options; if an investigation is pursued, the reporting party who identified themselves will be notified General Information 5.0 Contacting Outside Agencies In addition, employees who believe they have been unlawfully harassed on the basis of a protected characteristic have the right to file a complaint with the federal Equal Employment Opportunity Commission or the California Department of Fair Employment and Housing, which have the authority to remedy violations. Employees, students, and others participating in Caltech's educational programs and activities may file complaints with the U.S. Department of Education Office for Civil Rights (415) 486-5555, ocr.sanfrancisco@ed.gov or (800) 421-3481 or OCR@ed.gov. Complaints may also be directed to the Bureau for Private Postsecondary Education at bppe.ca.gov. 6.0 Investigation of Complaints Caltech will conduct a fair, timely, and thorough investigation into complaints within the scope of this policy to determine what occurred and take reasonable steps to remedy the effects of any harassment and prevent recurrence of the behavior. Caltech provides all parties with appropriate due process and reaches conclusions based on the evidence collected. Caltech takes appropriate action, including disciplinary measures up to and including termination of employment, student expulsion, or being permanently banned from Caltech premises, when warranted. 7.0 Prohibition Against Retaliation No one may intimidate, threaten, coerce, or discriminate against any individual for the purpose of interfering with any right or privilege secured by this policy or the related procedures, or because the individual has made a report or complaint, testified, assisted, participated, or refused to participate in any manner in any action or process under this policy or the related procedures. Intimidation, threats, coercion, or discrimination, for the purpose of interfering with any right under this policy or the related procedures constitutes retaliation. The rights and privileges secured under this policy and the related procedures include but are not limited to: (i) filing or assisting in the filing of a complaint or report of a suspected violation of this policy; (ii) opposing any act or practice made unlawful by any federal, state, or local laws requiring equal opportunity; (iii) participating, assisting, or otherwise cooperating in an investigation, compliance review, hearing, or any other activity related to a violation of this policy or administration of any federal, state, or local law requiring equal opportunity; and/or (iv) exercising any legal right protected by federal, state or local law requiring equal opportunity. Complaints of retaliation will be addressed under the Procedures for Complaints of Unlawful Discrimination, Harassment and Retaliation. The following actions do not constitute retaliation: the exercise of rights protected under applicable law or Caltech's charging an individual with a policy violation for making a materially false statement in bad faith in the course of a resolution process. A determination that a respondent was or was not responsible for alleged misconduct alone is not sufficient to conclude that any party made a materially false 125 Institute Policies 126 statement in bad faith. 8.0 Privacy A member of the Caltech community who wishes to report unlawful discrimination, harassment, or retaliation should do so as soon as possible, although reports (hereinafter "complaints") may be made at any time. Complaints can be made orally or in writing. Complaints should be brought to the attention of one of the individuals designated in this policy. Privacy generally means that information related to a report of harassment will only be shared with those individuals who have a "need to know." The determination of who has a "need to know" is within the discretion of Caltech. These individuals are required to be discreet and respect the privacy of all individuals involved. No meetings or conversations that take place under this policy or the Procedures for Complaints of Unlawful Discrimination, Harassment, and Retaliation may be audio-visually recorded by anyone. 9.0 Confidential Resources Caltech offers members of the Caltech community the choice of seeking confidential counseling outside of Caltech's procedural mechanisms for resolving unlawful harassment complaints. These confidential counseling services are intended for the personal benefit of the individual and offer a setting where various courses of action can be explored. Members of the Caltech community may access the offices below for confidential support. Counselors and designated confidential advocates in these offices will listen and help identify options and next steps. Talking to any of these staff members does not constitute reporting an incident to Caltech. Confidentiality generally means that information shared by an individual with designated campus or community professionals cannot be revealed to any other individual without the express permission of the individual. These professionals are listed below. They are prohibited from breaking confidentiality unless there is an imminent threat of harm to self or others or as otherwise required or permitted by law. When a report involves suspected abuse of a minor under the age of 18, these confidential resources may be required by state law to notify child protective services and/or local law enforcement. An individual who has experienced unlawful harassment and who first requests confidentiality may later decide to file a complaint with Caltech. The mental health professionals and other confidential resources listed below will provide the individual with assistance in filing a complaint if the individual wishes to do so. Mental health professionals in the Student Wellness, Counseling Services, and the Staff and Faculty Consultation Center provide mental health counseling services to the campus community. The JPL Employee Assistance Program provides mental health counseling services to the JPL community. They will not report any information about an incident to Caltech, including the Title IX coordinator, unless requested by their client. They can be contacted 24 hours a day/7 General Information days a week at: For students: Student Wellness, Counseling Services: (626) 395-8331 An after-hours counselor may be reached by calling Counseling Services' main number and pressing '2': (626) 395-8331 For faculty, campus staff and postdoctoral scholars: Staff & Faculty Consultation Center: (626) 395-8360 After hours via Security: (626) 395-5000 For JPL employees: Empathia (identify yourself as a JPL employee) www.mylifematters.com (Password: JPL): (800) 367-7474 Other Confidential resources are: Campus Hotline: (626) 395-8787 or (888) 395-878 JPL Ethics Hotline: (818) 354-9999 10.0 Equal Employment Opportunity Coordinators and Title IX Coordinator Caltech has designated Equal Opportunity coordinators (EO coordinators) who are responsible for assisting with and coordinating the education and compliance efforts relating to equal opportunity and nondiscrimination laws and Caltech policies. The following individuals have been designated as EO coordinators: the provost is the coordinator for faculty; the assistant vice president for human resources is the coordinator for campus staff, postdoctoral scholars, and volunteers; the associate deans of students are the coordinators for undergraduate students and interns; the dean of graduate studies is the coordinator for graduate students and interns; and the director for human resources at the Jet Propulsion Laboratory is the coordinator for employees, interns and volunteers assigned there. The assistant vice president for equity and equity investigations, who manages the Equity and Title IX Office, also has been designated as Caltech's Title IX coordinator. The contact number is (626) 395-3132, email: equity@caltech.edu, or visit the office in Room 205, Center for Student Services. 11.0 Informational Resources Information on unlawful harassment, as well as copies of Caltech's Nondiscrimination and Equal Employment Opportunity, Unlawful Harassment, Sex- and Gender-Based Misconduct, and Violence Prevention policies, are available from Caltech's Title IX coordinator and deputy coordinators; Human Resources, Student Affairs and Deans offices; the Caltech Center for Inclusion & Diversity; resident associates; the Staff and Faculty Consultation Center; and Employee & Organizational Development at Campus; and Employee Relations and the Human Resources Business Partners at JPL. The policies are published in the Caltech Catalog and on the following Caltech websites: Caltech Human Resources, JPL Human Resources, Equity and Title IX Office, and Student Affairs. 127 Institute Policies 128 Related Policies and Procedures: Nondiscrimination and Equal Employment Opportunity Policy Procedures for Complaints of Unlawil Discrimination Harassment and Retaliation : Sex- and Gender-Based Misconduct Policy Procedures for Complaints of Sexual Misconduct Under Title IX and the California Education Code • Violence Prevention Policy WHISTLEBLOWER POLICY 1.0 Policy It is important to Caltech that employees disclose violations or potential violations of law or other serious breaches of conduct without the fear of retaliation. Caltech policy prohibits retaliation against an individual who makes a good faith disclosure of suspected wrongful conduct. Any individual who engages in retaliation in violation of this policy will be subject to disciplinary action up to and including termination of employment or permanent separation from Caltech. It is Caltech's policy to comply with applicable laws and regulations, including California's whistleblower law protections provided under Labor Code Section 1102.5 and the whistleblower rights and remedies provided under 41 USC Section 4712, which are summarized at Enhancement of Employee Whistleblower Protection. As employees of Caltech, each individual is responsible for making sure their conduct fully complies with all laws and regulations as well as Institute policies. Caltech expects employees with knowledge of specific acts that they reasonably believe violate the law or Caltech policy to disclose those acts to an appropriate Caltech official. 2.0 Reporting An employee who becomes aware of any inappropriate or improper activity, or who believes they have been the subject of retaliation for making a good faith disclosure, is encouraged to contact their supervisor or one of the following offices: Human Resources, JPL Ethics Office, Audit Services and Institute Compliance (ASIC), or the Office of General Counsel. Anyone with questions or concerns regarding inappropriate or improper activities within Caltech may use one of the anonymous reporting mechanisms outlined below.

Caltech takes all such reports seriously and responds appropriately. These procedures apply to the following: At Campus and JPL, these procedures apply to allegations of Prohibited Conduct, as defined in the Sex- and Gender-Based Misconduct Policy, that do not fall under the definitions of sexual misconduct under Title IX or the California Education Code, as set out in Sections 15.0 and 16.0 of that policy. Therefore, for example, these procedures apply to allegations of sex- and gender-based discrimination and sex- and gender-based harassment, as set out in Section 17.0 of the Sex- and Gender-Based Misconduct Policy. Additionally, at JPL, these procedures apply to allegations of Prohibited Conduct under the Sex- and Gender-Based Misconduct Policy that do fall under Title IX and the California Education Code (Sections 15.0 and 16.0 of the Sex- and Gender-Based Misconduct Policy) but that do not occur in JPL education programs or activities. Caltech's Sexual Misconduct Procedures apply to allegations of Prohibited Conduct, as defined in the Sex- and Gender-Based Misconduct Policy, that fall under the definitions of sexual misconduct under Title IX or the California Education Code, as set out in Sections 15.0 and 16.0 of that policy. A member of the Caltech community who wishes to report unlawful discrimination, harassment, or retaliation should do so as soon as possible, although reports (hereinafter "complaints") may be made at any time. Complaints can be made orally or in writing. Complaints should be brought to the attention of the Title IX Coordinator or one of the individuals designated in the Unlawful Harassment Policy. Any reference to a Caltech administrator in this document is understood to include not only that administrator but also their designee. 2.0 Complaint Complaints of discrimination, harassment, and retaliation can be reported to the individuals designated in the Unlawful Harassment Policy. Consistent with Caltech's Unlawful Harassment Policy, Caltech will conduct a fair, timely, and thorough investigation into complaints within the scope of this policy to determine what occurred and take reasonable steps to remedy the effects of any harassment and prevent reoccurrence of the behavior. Caltech provides all parties with appropriate due process and reaches conclusions based on the evidence collected. Caltech takes appropriate action, including disciplinary measures, when warranted. 129 Institute Policies 130 The complainant and the respondent may object to an investigator/s assigned to a complaint only on the basis that the investigator has a conflict or cannot be impartial. The Equity and Title IX Office on campus or Human Resources at JPL will consider any objections and notify the parties of the decision related to the investigator/s. Such objections must be made in writing to the Equity and Title IX Office on campus or to the manager of Employee Relations at JPL and must include the reason for the objection. At any time, Caltech may put in place supportive or interim measures as appropriate to support the complainant, the respondent and/or others. 3.0 Investigation Steps • The complainant and respondent will be provided with a copy of the Nondiscrimination and Equal Employment Opportunity policy, the Unlawful Harassment policy, the Sex- and Gender-Based Misconduct Policy, and/or these procedures, as appropriate. • Within a reasonable length of time after the complaint has been reported, the complainant and the respondent will each be notified of the allegations to be investigated • The complainant and respondent will be informed that Caltech does not tolerate retaliation, takes steps to prevent retaliation, and takes strong responsive action if retaliation occurs. The complainant and respondent will be advised to notify Caltech immediately if retaliation occurs. • The investigation will be treated as private to the extent possible. Caltech will make reasonable and appropriate efforts to preserve the complainant's and respondent's privacy and protect the confidentiality of information but may need to share information on a need-to-know basis. • The investigation and adjudication of alleged prohibited conduct under this section is not an adversarial process between the complainant, the respondent, and the witnesses, but rather a process by which Caltech complies with its obligations under existing law and determines whether the allegations are substantiated by a preponderance of the evidence. • The complainant and the respondent will be given an opportunity to be interviewed regarding the allegations and may suggest witnesses or information to the investigator/s, who will determine whether the suggestions are relevant, appropriate, or necessary to resolve disputed-fact issues. The investigator/s may also review other information and interview others they determine may have information relevant to investigating and resolving the complaint. • Legal counsel and other advisers or support persons are not permitted to be present during interviews. Investigatory meetings will not be recorded by any party involved in a case. • Complaints will be investigated and resolved within a reasonably prompt time frame after the complaint has been made, though General Information factors, including but not limited to the complexity of the case, may impact the duration of the investigation. It is within the discretion of the Assistant Vice President of Equity or Human Resources at campus, or the Manager of Employee Relations at JPL, to determine whether to conclude an investigation without further opportunity to provide evidence by a party or witness who fails to cooperate reasonably and timely in providing evidence (e.g., failing to schedule or appear for meetings, failing to provide evidence they said they would provide, ignoring communications from the investigator). • The investigator/s will use the preponderance of the evidence standard in reaching findings and conclusions.

Student Affairs Policies Section Two Areas of Study and Research 134 Areas of Study and Research AEROSPACE The Guggenheim Aeronautical Laboratory, the Kármán Laboratory of Fluid Mechanics and Jet Propulsion, and the Firestone Flight Sciences Laboratory form the Graduate Aerospace Laboratories, widely known as GALCIT. In this complex are housed the solid mechanics, impact mechanics, and deployable space structures laboratories, the hypersonics and hydrodynamics facilities, the explosion dynamics and detonation physics laboratories, and the Joe and Edwina Charyk Laboratory of Bioinspired Design and Biopropulsion, the Center for Autonomous Systems and Technologies, as well as the various disciplines making up the broad field known as aerospace. Areas of Research Aerospace has evolved at Caltech from a field of basic research and engineering, primarily related to the development of the airplane, into a wide discipline encompassing a broad spectrum of basic as well as applied problems in fluid dynamics and mechanics of solids and materials and design and control of autonomous systems. Educational and research thrusts include the application of mechanics to various aspects of space exploration and to the study of biosystems and biopropulsion. Research at GALCIT has traditionally pioneered exploration of areas that have anticipated subsequent technological demands. This tradition places a high premium on in-depth understanding of fields both closely and remotely related to the behavior of fluids, solids, combustion, materials, and structures, such as physics, applied and computational mathematics, dynamical systems, earthquake physics, atmospheric studies, materials science, micro- and optoelectronics, microfluidics, bioinspired design, biomedical devices, and even astrophysics. GALCIT students are known and sought after for their broad yet intense education and for their ability to deal with new and challenging problems. Major areas of experimental, theoretical, and numerical research currently pursued by aerospace students at Caltech are briefly • Mechanics of Lightweight Space Structures. Current efforts in the field of next-generation deployable space structures aim to increase reliability and also lower fabrication and assembly costs by moving toward structures that consist of only a small number of separate pieces able to undergo large elastic deformations. These elastic-stored-energy structures return to their original, unstressed configuration when they are released in orbit. The design of these structures requires accurate structural models that incorporate geometry change and contact effects in sufficient detail to capture the actual behavior that is observed in ground tests. Local and global instabilities are often observed during folding/deployment, and their effects can also be very important. Ultimately, validation against space-based experiments will be pursued for a selected number of structural configurations. In parallel to these studies, thermomechanical Aerospace 135 136 constitutive models for ultrathin composite materials for these novel deployable space structures are being developed. Extensive studies of the deployment, elastic, and viscoelastic stability of stratospheric balloons are also being conducted. • Physics of Fluids. Fluid dynamics as a discipline is as much a part of physics as of engineering. Physics of fluids refers to research in areas closer to applied physics than to direct technical applications. Present active research includes studies in gas dynamics and hypervelocity flows, diffraction and focusing of shock waves, detonation waves, shock-induced Rayleigh-Taylor and Richtmeyer-Meshkov instabilities, transient supersonic jets, the development of laser-scattering diagnostic techniques for fluid-flow measurements, the study of structures and mechanics in transition and turbulence, studies of two-phase flows and turbulent mixing, chemically reacting flows, and experimental manipulation and control of wall-bounded flows for improved flow characteristics, such as reduction of drag, noise, and structural loading. • Physics of Solids and Mechanics of Materials. Mechanics of materials research involves both the quasi-static and dynamic characterization of the mechanical behavior and failure of solids. In order to understand materials for applications in a wide range of structures germane to aerospace as well as other engineering disciplines, both the physical foundations of that behavior and the mathematical or numerical representation of such behavior needs to be understood. Accordingly, studies involve material response at both the macroscopic (continuum) scales and the micro- and nanoscales. Of interest are the typical engineering metals, multiphase (composite) materials, polymers and ceramics, thin film materials used in microelectronic and optoelectronic applications, soft tissue mechanics of materials, and active materials used in structural actuation and controls. Other areas of active research include the study of highly nonlinear dynamics in solids, multiscale acoustic metamaterials, the analysis and design of mechanical metamaterials for the extreme conditions in air and space applications, and nondestructive evaluation/structural health monitoring of structures. • Space Technology. The goal of industrial utilization and exploration of space requires that one addresses a wide range of engineering problems. Examples of research activities include lightweight structures for large aperture systems, in-space manufacturing, material and structural behavior in extreme temperature and radiation environments, spacecraft shielding against hypervelocity impact threats, the mechanics of sample containment for planetary protection, low-g biomechanics, biomimetics of locomotion in planetary atmospheres, hypersonic reentry into planetary atmospheres, in-space propulsion, guidance, navigation and control, and launch-vehicle performance and safety. Opportunities exist for research in collaboration with the Jet Propulsion Laboratory. Areas of Study and Research • Computational Solid Mechanics. Computational solid mechanics addresses phenomena ranging from the atomistic scale, e.g., nanostructured materials or nanoscale structures and devices, to the structural scale, e.g., fracture of aircraft or spacecraft components, modeling of large space structures or even dynamic fragmentation phenomena accompanying hypervelocity impact. It provides an indispensable tool for understanding the relation between structure and mechanical properties of materials, for predicting the efficiency of such industrial processes as machining and metal forming, and for assessing the safety of such structures as airplanes, spacecraft, automobiles, and bridges. The goals and objectives of this activity are to provide a state-of-the-art environment for the development of numerical methods in solid mechanics, to provide the computational resources required for large-scale simulations in solid mechanics, and to serve as an instructional facility for advanced courses. • Computational and Theoretical Fluid Dynamics. Many of the fluid dynamics phenomena studied experimentally at GALCIT are also being investigated by numerical simulation and by theoretical analysis. Present active research areas in computational and theoretical techniques include direct numerical simulation, particle methods for flow simulation, new algorithms and subgrid-scale models for compressible and incompressible flows, large-eddy simulation methods, flows with shocks and driven by shocks, analytical and computational techniques for turbulence structure diagnostics, analysis of turbulent mixing dynamics, high-explosive interactions with deformable boundaries, chemically reacting flows, and detailed chemical reaction kinetics in flames and detonations. Mechanics of Fracture. An active effort is being made to understand mechanisms in a wide range of fracture problems. Aspects that are studied include quasi-static and dynamic crack growth phenomena in brittle and plastically deforming solids, polymers and advanced composites, as well as fatigue and failure of adhesive bonds. Research areas adjunct to dynamic fracture studies are those of dynamic localization in metals and of failure in frictional interfaces. These include the study of shear rupture phenomena in both coherent and incoherent interfaces. The dynamic failure of modern composite and layered materials and the phenomenon of earthquake rupture growth along geological faults have motivated these studies. • Aeronautical Engineering and Propulsion. Research in the aeronautical engineering area includes studies of airplane trailing vortices and separated flows at high angles of attack. Research work in the propulsion area has centered on the fluid dynamic problems associated with combustion, solid propellant rocket motor instabilities, fluid dynamics and optimization of scramjets, and pulse detonation engines. • Biomechanics of Fluids and Solids. The kinematics and dynamics of fluid flows in biological systems are studied in experiments, numerical simulations, and theoretical analyses. These flows are Aerospace 137 138 often characterized by unsteady vortex dynamics, coupled fluid interactions with flexible material surfaces, non-Newtonian fluid behavior, and, in some cases, compressibility. Areas of active research include animal swimming and flying, cardiovascular fluid dynamics and hemodynamics, the mechanics of morphing/active deformable surfaces for flow control, and biologically inspired design of engineering systems. • Technical Fluid Mechanics. These areas are related to a variety of modern technological problems and, in addition, to the traditional aeronautical problems of drag, wing stall, and shear flow mixing. Additional areas of activity include bluff-body aerodynamics, fluid-structure interaction, turbulent combustion, laminar diffusion flames and their instabilities, explosions, hydrodynamics and two-phase flows, interaction of vorticity with free-surface, cardiac flows, swimming and flying, and active and passive control of transition and turbulence. Acoustics problems studied include jet noise, combustion noise, and instabilities such as the generation of organ pipe oscillations in large burners of electric generating plants. • Fluid Mechanics, Control, and Materials. The effects of boundary conditions on turbulence characteristics and general flow physics, scaling and controllability are investigated using interdisciplinary methods based on developments in materials science and control techniques. Experimental manipulation of canonical and simple model flows is used to probe fundamental issues of flow physics and control. • Autonomous Systems and Technologies. Interdisciplinary research in the expanding area of autonomous systems involves, but are not limited to, drones, robots, and spacecraft for use in science, exploration, and transportation. The research addresses sensing, control, vision, machine learning, and other emerging areas. Advanced drone research, autonomous exploration, and swarm robotics will draw research from the full range of engineering at Caltech, the geological and planetary sciences division, and JPL. Physical Facilities The Graduate Aerospace Laboratories contain a diversity of experimental facilities in support of the programs described above. The Cann Laboratory is a teaching facility utilized for graduate and undergraduate experiments in fluid and solid mechanics. Low-speed wind tunnels include the John W. Lucas Adaptive Wall Tunnel, the Merrill Wind Tunnel, and special-purpose flow facilities. Smaller water channels and a tow tank for studies of wave motion and flow visualization are also available. For investigations of high-speed flows, there is a Ludwieg tube, a supersonic shear layer facility, a hypervelocity expansion tube, and the T5 shock tunnel for studying hypervelocity gas flows up to 7 km/s. Shock tubes and other special facilities are available for the study of extreme temperatures, shock waves, deflagrations, detonations acoustics, and combustion at variable pressure conditions. Areas of Study and Research The Center for Autonomous Systems and Technologies (CAST) contains an 85-foot track for walking robots and a wholly enclosed 75,000 cubic foot aerodrome for drone testing which is the tallest of its kind. Environmental simulation is provided by a 100-square-foot wall comprised of 1,296 fans capable of generating wind speeds of up to 44 mph, along with a side wall of an additional 324 fans, all of which can be individually controlled to create a nearly infinite variety of The solid and structural mechanics laboratories contain standard as well as special testing facilities for research related to aircraft, deployable space structures, and failure/fracture behavior of materials under static and dynamic loads, including three servo-hydraulic facilities, two of which operate on a "tension/torsion" mode, and a nanoindenter. A range of digital and film high-speed cameras offering recording at rates up to 100 million frames per second are available for the study of fast phenomena, such as wave propagation, hypervelocity impact, and the mechanics of static and dynamic fracture. Dynamic testing facilities include specialized electromagnetic loading devices (stored energy ~ 120 kJ), a drop weight tower, split Hopkinson bars (axial/torsional), and plate impact apparatus. Diagnostic devices include full-field interferometric and high-speed temperature measurements, both for static and dynamic applications. Other specialized facilities include a Class One clean room area that houses microelectronic wafer inspection metrology tools, and the Small Particle Hypervelocity Impact Range (SPHIR) jointly operated with JPL, which is capable of launching micrometeoroid surrogate particles at speeds up to 8 km/s. Facilities are available for scanning microscopy (AFM, STM) and electromechanical characterization of materials. Other assets include state-of-the-art electronic instrumentation and computer systems for real-time control of experiments, data acquisition, processing, storage, and digital image processing. Computational facilities include powerful workstations, on-campus high-performance computing machines, and remote supercomputers such as those generally available at NSF, NASA, and DOE centers. Graphics workstations are available to support research in computational fluid dynamics and solid mechanics. APPLIED AND COMPUTATIONAL MATHEMATICS An interdisciplinary program of study in applied and computational mathematics that leads to the Ph.D. degree is offered by the Computing & Mathematical Sciences department. In addition to various basic and advanced courses taught by the applied and computational mathematics faculty, broad selections are available in mathematics, physics, engineering, and other areas. Students are expected to become proficient in some special physical or nonmathematical field. A subject minor in applied computation is Applied and Computational Mathematics 139 140 offered jointly with the computer science option. In addition to the applied and computational mathematics faculty, professors from other disciplines such as mathematics, physics, engineering, and biology supervise research and offer courses of special interest. The applied and computational mathematics group has access to supercomputers and concurrent computers. The present graduate program is one leading mainly to the Ph.D. degree. The curriculum consists of two types of courses: those that survey the methods used in applied and computational mathematics, and those that have a special applied and computational mathematics flavor and represent active research interests of the members of the faculty. Among the latter have been wave motion, perturbation theory, fluid mechanics, optimization, stochastic processes, wavelet analysis, signal processing, numerical analysis, computational electromagnetism, computational fluid dynamics, mathematics of data science, probability, random matrix theory, applied algebraic geometry and statistical inference, game and decision theoretic approaches to numerical approximation and learning, homogenization, multifidelity and multiscale analysis, and stochastic modeling, stochastic analysis, data assimilation, and inverse problems. Through study outside of applied and computational mathematics, each student is expected to become competent in some special physical or nonmathematical field. In this way, subjects for research appear naturally, and a broad educational program is provided. The group primarily interested in applied and computational mathematics currently consists of approximately 25 students and eight professors. Also, each year many distinguished visitors come either to present lectures or remain in residence for large parts of the academic year.

Physical Facilities See Mechanical Engineering and Civil Engineering. APPLIED PHYSICS The Applied Physics option was instituted in 1970 in order to provide an interdivisional program for undergraduate and graduate students at Caltech interested in the study of both pure and applied physics. The small size of Caltech, coupled with its strength in the basic sciences and engineering, has made it possible for faculty and students alike to pursue wide-ranging interests in the application of modern physics to the development of new technology. Research efforts in applied physics are driven by a fundamental understanding of the physical principles underlying applications and a strong motivation to use this knowledge to invent new experimental techniques, processes, devices and materials. Core and affiliate faculty spanning several divisions on campus participate in instruction and research leading to B.S., M.S., and Ph.D. degrees in applied physics. This program is designed for undergraduate and graduate students who wish to expand their training beyond the study of fundamental physics to include research and development of real-world applications. The training helps develop a solid foundation in physics through introductory courses in classical physics, classical electrodynamics, quantum mechanics, thermodynamics, statistical mechanics, and mathematical physics. More advanced training is provided through coursework and research activities in solid state physics, electromagnetic wave propagation, optoelectronic materials and devices, transport phenomena in hydrodynamic and condensed matter systems, plasma physics, biological physics, semiconductor principles and devices, quantum electronics, and low-dimensional electronic systems. Students are encouraged early on to develop strong experimental skills for advanced laboratory work, including familiarity with numerical Applied Physics 141 142 computation for data and image analysis and software packages for instrument automation. There exist many learning opportunities along these lines, from courses in microfabrication and laboratory work to independent research opportunities with various research groups. Undergraduate students are encouraged to explore and will find numerous opportunities for developing their research interests into junior or senior thesis projects leading to publication. Physical Facilities Research in applied physics covers a broad spectrum of activities distributed across campus. Instructional and research activities of the core faculty are housed in the Thomas J. Watson, Sr. Laboratories of Applied Physics, a 40,000-square-foot building with state-of-the-art research laboratories, a central microfabrication facility, faculty and student offices, and a conference room and instructional classroom, all nestled around a beautiful courtyard with a fountain pool. Additional research laboratories and faculty and student offices are located in the Harry G. Steele Laboratory of Electrical Sciences, built in 1965 with funds from the Harry G. Steele Foundation and the National Science Foundation. The building, which is connected by an overhead bridge to the Watson Laboratories, conveniently also houses the Kavli Nanoscience Institute. ASTROPHYSICS Caltech is one of the world's preeminent centers of astronomical research. This is due to the combination of excellent human resources with premier observational facilities and computational infrastructure. Fundamental discoveries in astronomy and astrophysics are a part of Caltech's past, present, and future. Students from either the astronomy or the physics options are best prepared to undertake research with faculty in the Cahill Center for Astronomy and Astrophysics. Students from related options such as planetary science, computer science, applied physics, and electrical engineering are also welcome. Areas of Research Astronomy and astrophysics are synonymous at Caltech. Caltech scientists and students are involved in many frontier areas of research, and have been known to open new ones. Research techniques include observations, theory, numerical simulation, advanced data analysis, laboratory astrophysics, and detector development. Projects and groups often bridge these areas of inquiry. Topics of current research interest include: observational cosmology and the nature of dark matter and dark energy; studies of the cosmic microwave background; galaxy formation and evolution; quasars and other active galactic nuclei and radio sources; studies of the dynamics and composition of galaxies and clusters; physics and evolution of the intergalactic medium; interstellar matter; local star and planet formation; extrasolar planetary systems; the structure of the galaxy; globular clusters; stellar abundances; supernovae, gamma-ray Areas of Study and Research bursts, and other types of cosmic explosions and transient phenomena; neutron stars and black holes; accretion disks; digital sky surveys and astroinformatics; numerical general relativity; gravitational wave astronomy and many others. Research in planetary and solar system astronomy is often pursued in cooperation with groups in the Division of Geological and Planetary Sciences. New types of astronomical detectors and satellites, that can revolutionize various areas of astronomical research, are developed with groups in physics and colleagues at JPL. In addition to maintaining a leading numerical general relativity group, Caltech theorists also use high-performance computing facilities for simulations of supernova explosions, merging black holes, cosmic structure formation, etc. Caltech is leading the development of novel tools for knowledge discovery in massive and complex astronomical data sets, many obtained with Caltech facilities. History and Current Science at Observational Facilities Observational astronomy is pursued both from the ground-based sites and from space-based platforms. Caltech operates, or has access to an unprecedented, comprehensive set of observational facilities, spanning the entire electromagnetic spectrum. Caltech is also playing a key role in opening a new window on the universe, the gravitational wave sky. Historically, Caltech's pioneering role in astronomy started with Palomar Observatory (about 190 km from campus), funded by the Rockefeller Foundation. The first telescope on the mountain was an 18-inch Schmidt telescope built by Fritz Zwicky and used to conduct pioneering sky surveys for supernovae, potential planetary hazard asteroids, etc. The 200-inch Hale Telescope, constructed through the 1930s and 1940s, has been used to make many historical, fundamental discoveries ever since its commissioning in 1948, including the discovery of quasars, and many studies of stellar populations, galaxies, intergalactic medium, etc., and it continues to produce excellent science. Novel detectors and instruments were developed there, e.g., the first astronomical CCDs and infrared detectors as well as pioneering advances in adaptive optics in addition to optical and infrared spectroscopy. The 48-inch Samuel Oschin Telescope has made possible complete surveys of the northern sky, initially with photographic plates (including the historic POSS-I and POSS-II surveys), and now with large-format CCD array cameras. It is currently operating a uniquely wide field, high-cadence program, the Zwicky Transient Facility (ZTF). A much larger camera for this telescope, with a 47-square-degree field, started operation in 2018, as the Zwicky Transient Facility (ZTF). The 60-inch telescope has been roboticized, and is used to monitor sources discovered by sky surveys. In the 1990s, funded mainly by the Keck Foundation, Caltech and University of California constructed two 10-m telescopes on Mauna Kea, Hawaii. The W. M. Keck Observatory produced many recent discoveries in the fields of galaxy formation and evolution, intergalactic medium, extrasolar planets, cosmic gamma-ray bursts, etc. Caltech is Astrophysics 143 144 a founding partner in the development of the Thirty-Meter Telescope (TMT), the first of the next generation of extremely large optical/infrared telescopes. At meter to centimeter wavelengths, Caltech operates the Owens Valley Radio Observatory (OVRO) in a radio-quiet location about 400 km from Pasadena, near Big Pine, California. Its facilities include a 40-meter telescope, a growing 288 element long wavelength array which can image the entire sky every second, and a 6.1 meter telescope dedicated to observations of polarized radio emission from the galaxy. New radio and submm telescopes are in design and construction phases. From the 1980s until 2015, Caltech also operated the Caltech 10-m Submillimeter Observatory (CSO) on Mauna Kea in Hawaii, and a series of millimeter interferometers, culminating in the 23-antenna Combined Array for Research in Millimeter-wave Astronomy (CARMA) in the Inyo Mountains. These telescopes, currently being repurposed to new experiments, pioneered submm imaging and interferometry and mm wave interferometry, now carried out by the international Atacama Large Millimeter/submm Array (ALMA). In Antarctica, Caltech's BICEP2 telescope, which measures the imprint of inflation's gravitational waves on the COSMIC microwave background, has been expanded and renamed the Keck Array. On the space observations front, Caltech hosts NASA's Spitzer Science Center (SSC) and IPAC, which are principal national archives for astronomy. Caltech scientists lead or actively participate in a number of astrophysics missions, currently including the Spitzer Space Telescope, and the NuSTAR hard X-ray mission. Caltech and the Jet Propulsion Laboratory (JPL) are also leading the development of the forthcoming SPHEREx mission, that will study the early stages of the universe, galaxy formation, and formation of planetary systems. There are numerous close connections with JPL, that designs and operates a number of NASA's scientific missions. Finally, Caltech astronomers are major users of NASA's astronomical satellites, the Hubble Space Telescope, Chandra, Fermi, Herschel, Planck, etc., ALMA and the NSF's Jansky Very Large Array (JVLA). Caltech is the headquarters for LIGO lab, which built and operates the world's most sensitive gravitational wave observatory, the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO), which in 2015 made the historic first detection of gravitational waves from a black hole binary. Several other black hole mergers have been detected since then, as well as the first gravitational wave detection of a merger of two neutron starts in 2017. Numerous other discoveries are expected as the operations continue. Areas of Study and Research BIOCHEMISTRY AND MOLECULAR BIOPHYSICS The Biochemistry and Molecular Biophysics (BMB) option has been established as an interdisciplinary program, at the interface of biology, chemistry, and physics, that seeks to understand the chemistry of life. Thus, BMB students study the atomic structure and folding of biopolymers; their interactions with each other and with small molecules; and the roles of particular biopolymers and biopolymer assemblies in cellular physiology. The basic building block of life is the cell; the intellectual focus of modern biochemistry and molecular biophysics is to understand how individual parts interact to give cells their wide spectrum of functions. In particular, biochemistry and molecular biophysics addresses the principles through which the individual components of cells combine in an orderly self-association to produce their form, their function, and their dynamic behavior. Areas of Research General areas of research represented within the option include signal transduction, cell cycle, DNA and RNA structure and metabolism, control of gene transcription during development, protein folding, biogenesis and quality control, electron transport proteins and bioenergetics, biological catalysis, macromolecular structure, membrane proteins, and biotechnology and biomolecular engineering. More specific examples of biological phenomena currently under study include the transduction of signals received by cell surface receptors into an appropriate response, as in chemotaxis or transmission of signals across synapses in the nervous system; the replication of DNA; the biochemical networks that control initiation and termination of cell division; the controlled transcription of DNA sequences in the genome into RNA and the processing of this RNA into mRNA and the subsequent translation into protein; energetic principles and molecular mechanisms that underlie the biogenesis of nascent proteins and maintenance of protein homeostasis in the cell; the molecular mechanisms controlling the differentiation of precursor cells into specialized cells such as neurons, lymphocytes, and muscle cells; the mechanisms by which synaptic transmission in the brain is regulated during thinking and the formation of memories; the processes, driven by fundamental principles of chemical bonding and molecular energetics, by which a given linear sequence of amino acids folds into a specific three-dimensional structure in the appropriate cellular environment; how electrons move within a cell to accomplish the many redox reactions necessary for life; how light is harvested by photo-pigments and is perceived in vision; the function of integral membrane proteins in energy and signal transduction processes; and the mechanisms by which enzymes both efficiently and specifically catalyze biochemical interconversions. This fundamental understanding of the molecular basis of biological processes provides a powerful base for the development of applications in medicine, including biotechnology and rational drug design, and in the chemical Biochemistry and Molecular Biophysics 145 146 industry, where nucleic acids, proteins, and their analogs are now being used in the development of chemical systems for novel applications, and where mutagenesis and selection systems are used to produce novel materials.

CHEMISTRY Caltech offers exciting opportunities for study and research at the frontiers of chemical science. With approximately 30 faculty, the chemistry program provides depth in the traditional areas of chemistry-organic and inorganic chemistry, chemical physics, theoretical chemistry, and chemical biology. Research areas include chemical synthesis and catalysis, chemical dynamics and reaction mechanisms, biochemistry, bioinorganic, bioorganic, and biophysical Areas of Study and Research chemistry, and materials chemistry. Chemical research at Caltech is also highly interdisciplinary, mirroring the increasing importance of molecular understanding in many fields of science. Active interactions exist between chemistry and other disciplines at Caltech, especially applied physics, biology, chemical engineering, environmental science, geological and planetary sciences, and materials science. Major initiatives are fostering broad collaborations in energy and environment, molecular medicine, and nanomaterials. Teaching is an important component of the chemistry option. Caltech has trained generations of chemists who have become undergraduate and graduate programs that are designed to encourage the greatest possible amount of freedom, creativity, and flexibility. Areas of Research Caltech has a long and continuing reputation for excellence in fundamental chemistry in molecular structure and the nature of chemical bonding. Much of the current research in chemistry is directed at establishing and manipulating the mechanisms of reactions of fundamental chemical and biological significance. Programs in chemical physics emphasize studies of molecular dynamics and structure using techniques that include femtosecond lasers, molecular beams, ultra-high sensitivity spectroscopy, and mass spectrometry, while novel methods such as ultrafast electron diffraction and force-detected magnetic resonance are being developed and applied to systems of increasing complexity. Interdisciplinary research includes the development of powerful approaches to fabricate, assemble, and utilize nanometer-scale structures; spectroscopy and fundamental chemical mechanisms of reactions in Earth and planetary atmospheres, star formation, and interstellar chemistry; the dynamics of phase transitions; and novel methods in mass spectrometry. Catalysis by transition metals represents a central area of research in the inorganic and organometallic areas. Current research interests include the uses of transition metal complexes as homogeneous and heterogeneous catalysts for polymer synthesis, solar energy conversion and storage, and methane and water oxidation. Reactions of molecules on surfaces are an important focus, especially on semiconductors. Research in bioorganic and bioinorganic chemistry includes the chemical basis of synaptic transmission by ion channels; investigations of molecular recognition and sequence-specific ligand binding to DNA; DNA-mediated charge transport; and design of artificial transcription activators. Chemical synthesis, a key part of much of the research described above, is the primary research goal of several groups, and includes projects aimed at the synthesis of complex organic molecules of importance in biology and human medicine. These efforts include development of new and synthetically useful chemical transformations mediated by novel organic and transition metal-based catalysts. The division has an exceptional program in polymer science, with emphasis on the development of strategies and methodologies for the Chemistry 151 152 synthesis of designed polymers using chemical- and biological-based approaches. The theoretical chemistry program ranges from fundamental studies of electron transfer to excited states and reaction dynamics of small molecules, to simulations of biological systems and materials. In these studies, theoretical techniques are being developed to provide detailed understanding of electron transfer processes, proton transfer reactions, energy randomization processes within molecules, and the dynamics of reacting systems. Computer simulations are addressing ever more complex systems, ranging from metals and superconductors to soft materials and biomolecules.

Physical Facilities The laboratories of chemistry consist of eight units providing space for about 25 research groups, including 300 graduate students and postdoctoral research fellows. Crellin and Gates laboratories house several research groups, the divisional instrumentation facilities, and the divisional administrative offices. Synthetic research groups occupy the Arnold and Mabel Beckman Laboratory of Chemical Synthesis and Church laboratories. The Braun Laboratories and the Broad Center for the Biological Sciences house biochemical groups and are shared with the Division of Biology and Biological Engineering. The Arthur Amos Noyes Laboratory of Chemical Physics is one of the major research facilities for chemical physics and inorganic chemistry and is adjoined by the Clifford S. and Ruth A. Mead Memorial Undergraduate Chemistry Laboratory. Chemistry groups recently joined several chemical engineering colleagues in the new Warren and Katharine Schlinger Laboratory for Chemistry and Chemical Engineering. A number of resource centers serving researchers of the division are located in the Beckman Institute. CIVIL ENGINEERING Civil engineering includes the research, development, planning, design, and construction associated with the infrastructure of the built environment. Dealing with the function and safety of such facilities as buildings, bridges, pipelines, dams, power plants, and harbors, it is concerned with the protection of the public against natural hazards such as earthquakes, winds, floods, landslides, water waves, and fires. Areas of Study and Research Recent advances in technology, the escalation of urban problems, and the exploration of space have broadened the applications of civil engineering, increasing the scope of research. New problems have presented special challenges to the civil engineer well-trained in the fundamentals of their profession. For this reason, in the advanced study of civil engineering at the Institute, the application of fundamental scientific principles and mathematics is emphasized for the solution of engineering problems. Areas of Research Graduate work leading to advanced degrees lies chiefly in the following fields: structural engineering and structural dynamics; earthquake engineering; applied mechanics; geotechnical engineering; aerospace structures; and environmental engineering (see also environmental science and engineering). In the past few years, graduate students and members of the faculty have pursued a variety of research programs, including the analysis of structures subjected to earthquakes and other dynamic loadings; optimal performance-based structural design; system identification and control of structures; structural health monitoring; the use of finite element methods for structural analysis; seismic risk and structural reliability; earthquake early warning systems; mechanics of soil and other granular materials; and mechanics of space structures. Students whose interests are in environmental problems may enroll for graduate degrees in either civil engineering or environmental science and engineering. Physical Facilities Civil engineering activities is housed in the Gates-Thomas Laboratory. Excellent computing facilities are available through the campus computing network and in the specialized computing centers of various research groups. Seismic instrumentation networks include the Southern California Seismic Network and the Community Seismic Network. COMPUTATION AND NEURAL SYSTEMS What does the brain compute? How does it do it? And why? Faculty and students in the CNS option study how information is acquired and processed by the brain. They are also interested in designing machines that are adaptable, intelligent, and autonomous. The unifying theme of the program is the study of the relationship between the physical structure of a computational system (synthetic or natural hardware), the dynamics of its operation and its interaction with the environment, and the computations that it carries out. Areas of interest include coding and computation in networks of neurons, sensory systems (vision, audition, olfaction), learning and memory, control and motor behavior, and planning and decision making. Thus, CNS is an interdisciplinary option that benefits from, and integrates, multiple traditional areas of expertise: molecular, cellular, neural, and systems biology, electrical and mechanical engineering, computer science, psychology, and cognition, applied Computation and Neural Systems 153 154 mathematics, and physics. Faculty in the program belong to the Division of Biology and Biological Engineering, Division of Engineering and Applied Science, Division of Physics, Mathematics and Astronomy, and Division of the Humanities and Social Sciences. They have an interest in developing conceptual frameworks and analytical approaches for tackling seemingly disparate problems that share a common deep structure at the computational level. Students in the program will partake of a wide-ranging curriculum that will promote a broad understanding of neurobiology, sensory psychology, cognitive science, computational hardware and software, and information theory. Areas of Research Areas of research include the neuron as a computational device; the theory of collective neural circuits for biological and machine computations; algorithms and architectures that enable efficient fault-tolerant parallel and distributed computing; learning theory and systems, pattern recognition, information theory, and computational complexity; computational modeling and analysis of information processing in biochemical and neural networks; the design and use of synthetic macromolecules as computational devices; light and magnetic resonance imaging of cell lineages, cell migrations, and axonal connections in the forming nervous system; learning, plasticity, and memory; experimental and modeling studies of localization and recognition by sensory systems (vision, olfaction, audition) in insects and vertebrates on the basis of electrophysiology, psychophysics, and functional imaging techniques; multiunit recordings in behaving animals; neuroprosthetic devices and recording methods in animals and humans; imaging and stimulation of cortical areas in humans and other primates using functional MRI, TMS, and DCS; decision making, attention, awareness, emotion, and consciousness in the primate brain using a combination of neurophysiological, psychophysical, and computer modeling techniques; cognitive psychology; and the study of evolution in natural and artificial systems. COMPUTER SCIENCE Computing is a ubiquitous tool in all areas of study and research at Caltech. Computer science focuses on the theory and technology of computation itself: it is the study of information, and of the structures that communicate, store, and procegs information. Whether these structures are expressed in hardware and called machines, in software and called programs, or in nature or society, the fundamental concepts are similar. Students of the computer science option within the Computing & Mathematical Sciences department at Caltech do not specialize along traditional lines that divide hardware and software, systems and applications, or theory and experiment. Rather, a unified approach to the design and analysis of computing structures is taken both in courses and in research. Managing the great complexity of useful Areas of Study and Research systems requires a representation of computations amenable to both mathematical treatment and implementation. Whether the system is artificially designed (such as a multi-core processor), or naturally occurring (such as a molecule), the computer scientist formalizes the computation performed by the system and provides a systematic analysis of its requirements and formal guarantees on its outcomes. Areas of Research Research and advanced courses leading to the Ph.D. degree in computer science are concentrated in the following areas: quantum and molecular computation; parallel and distributed computation; theory of computation; information theory; machine learning and applications; computational economics; computer vision; computer graphics; discrete differential geometry; networking and power systems. Research projects frequently involve work in several of these areas, with both theoretical and experimental aspects, as well as connections with such fields as mathematics, physics, biology, economics, and electrical engineering. Crosscutting themes include: • Physical Implementation of Computations. Computations must ultimately be implemented in some physical medium (e.g., semiconductor electronics, DNA self-assembly, quantum states of elementary particles, molecular electronics). Caltech has been a leader in the early development, engineering, and design of very large scale integrated (VLSI) circuits. Beyond VLSI, efforts are under way to understand quantum, biomolecular, and molecular electronic substrates as possible media for future computing machines. As was the case with semiconductor electronics, Caltech computing can draw on the world-class expertise of its biology, physics, and chemistry departments as it tackles the many challenging opportunities that these new substrates present. Robust Modeling of Physical Systems. Caltech computer science has a unique focus in developing rigorous and robust models of the physical world. These models are mathematically and physically sound, often derived from differential geometric principles, and serve as a basis for computer graphics and vision research, as well as the simulation of mechanical, optical, and biological systems. • Systematic Design. A key theme in the Caltech computer science option is the systematic design of systems at all levels. This theme shows up in the design of numerical algorithms for physical simulation and computer graphics, design of concurrent and distributed systems, abstractions for physical computing substrates, design of learning systems, design of programming languages, automated optimization of computations for both software and hardware implementation, as well as control and optimization of networks. The success of computer systems has allowed the building of systems of unprecedented scale and complexity. These systems can only be understood and managed if we carefully contain the complexity involved by Computer Science 155 156 systematically defining and exploring their design space. • Theory. A strong theoretical understanding is the necessary foundation for systematic design, analysis, and verification. The theory of computation focuses on deep mathematical problems, many of which have substantial technological impact. Theory in computer science at Caltech includes traditional areas such as complexity algorithms, theories of numerical computation, optimization, probability, and game theory. But theory is not relegated to a single group, and has strong connections to all • Networks & Distributed Systems. Modern networks and distributed systems are undoubtedly the most complex and critical pieces of infrastructure that the world has created. This includes communication networks as well as power networks, social networks, cloud computing, and more. The massive scale and exponential growth of such networks presents unique algorithmic, computational, and economic challenges. Research at Caltech approaches these challenges through a combination of rigorous design, systematic analysis, and interdisciplinary collaboration. • Machine Learning. In our increasingly data-rich world, it is more important than ever to develop principled approaches that can intelligently convert raw data into actionable knowledge. At Caltech, we take a broad and integrated view of research in data-driven intelligent systems. The Decision, Optimization and Learning group brings together researchers from machine learning, optimization, applied math, statistics, control, robotics, distributed systems and human-computer interaction to form an intellectual core pertaining fundamental and applied research from statistical machine learning to statistical decision theory through optimization. • Interdisciplinary Research. Computer simulations, modeling, and analysis are key enablers, allowing all fields of science to advance rapidly. Furthermore, insights into computational management of information helps us understand information processing issues in natural systems (from cells and neurons to financial markets and social networks) and build hypothetical models that advance our understanding of natural cognition. These relations provide many opportunities for scholars in computer science to work closely with colleagues throughout Caltech. The Information Science and Technology (IST) initiative facilitates and promotes such interdisciplinary research (see ist.caltech.edu). Physical Facilities The computer science option has excellent computing facilities ranging from high-performance workstations to multiprocessors and supercomputers. The Computing & Mathematical Sciences department maintains a large computer lab open to students and offers a large collection of software for a wide range of applications. Students have easy access to state-of-the-art equipment. The Institute Areas of Study and Research libraries maintain a large collection of journals in computer science and related fields. COMPUTING AND MATHEMATICAL SCIENCES Data-driven modeling is becoming increasingly critical in diverse application domains such as machine learning, vision, control systems, biological and engineered networks, neuroscience, economics, and privacy, as well as in many areas of the physical sciences, including high energy physics, earthquake modeling, astronomy, and exploration geophysics. There is enormous potential for research on data-intensive activity of this type, which is highlighted by the emergence of new fields such as "Big Data," "Decision Science," and "Network Science." However, the theoretical foundations of these subjects remain underdeveloped, limiting our understanding and development. The mission of the CMS graduate program is to address this need by exploring and developing the fundamental mathematical, computational, and economic tools necessary to advance data-intensive science and engineering. That is, we aim to forge the algorithmic foundations necessary to move from data, to information, to action. Key to this mission is a core focus on "algorithmic thinking." Algorithms are not just the basis for advanced technology, they are intrinsic components of diverse fields such as biology, physics, and economics. Studying the structures and mechanisms that communicate, store, and process information from this viewpoint —whether these structures are expressed in hardware and called machines, in software and called programs, in abstract notation and called mathematics, or in nature and society and called biological or social networks and markets—is crucial to pushing scientific boundaries. Simply put, it is almost impossible to do research in any scientific or engineering discipline without the ability to think algorithmically. Because of the diversity of fields where algorithmic thinking is fundamental, there are broad differences in how algorithms are formalized, applied, and studied across areas. Over the years, these differences have been codified and the "language of algorithms" is actually quite distinct across, e.g., computer science, applied math, and electrical engineering. However, a broad view of algorithmic thinking is crucial to scientific breakthrough; and the goal of this program is to train scholars to have an interdisciplinary, cross-cutting view of algorithms. Faculty and students in CMS are active in a broad array of research areas. Some of these include algorithms, complexity, algorithmic economics, feedback and control, inference and statistics, information systems, machine learning, networked systems, vision, optimization, quantum information, scientific computing, and uncertainty quantification. Computing and Mathematical Sciences 157 158 CONTROL AND DYNAMICAL SYSTEMS Some of the most exciting interactions between mathematics and engineering are occurring in the area of analysis and control of uncertain, multivariable, and nonlinear dynamical systems. While changing technology has made control and dynamical systems theory increasingly relevant to a much broader class of problems, the interdisciplinary nature of this area means that it no longer has a natural home exclusively or even primarily within any one of the traditional engineering disciplines. The CDS option, as part of the Computing & Mathematical Sciences department, is designed to meet the challenge of educating students both in the mathematical methods of control and dynamical systems theory and their applications to problems in engineering and science. Faculty and students in CDS are active in a number of research areas. The primary theoretical areas of research include stochastic and nonlinear dynamical systems, multiscale modeling, optimal and decentralized control, system identification and estimation theory, Bayesian modeling and analysis, uncertainty quantification, and communications and information theory. Active applications include networking and communication systems, embedded systems and formal verification, robotics and autonomy, molecular and systems biology, integrative biology, human physiology, economic and financial systems, computing systems, physics of fluids, quantum mechanics, seismology and earthquake engineering, and space systems. ELECTRICAL ENGINEERING Electrical engineering at Caltech emphasizes both devices and systems. Closely allied with computation and neural systems, applied physics, bioengineering, computer science, and control and dynamical systems, it offers students the opportunity for study and research, both theoretical and experimental, in a wide variety of subjects, including wireless systems, photonics, quantum information science, modern optics, biophotonics, MEMS/NEMS, solid-state materials and devices, power electronics, energy systems, control theory, data science, nanoscale systems, signal processing, learning, data compression, and communications.

ENERGY SCIENCE AND TECHNOLOGY The useful transformation of energy from one form to another drives the engine of civilization. Access to plentiful, inexpensive, and environmentally benign resources would free nations to pursue their greatest human and economic potential. In the modern era, the appetite for energy is convoluted, with a recognition of diminishing fossil fuel resources and of dramatic negative impacts on global climate. The interdisciplinary program in Energy Science and Technology (EST) aims to foster revolutionary methods of harnessing carbon-free energy sources while advancing related technologies in carbon sequestration and further drawing connections to policy and economic considerations. The program brings together traditional topics in thermodynamics and kinetics with modern topics in biomolecular engineering, charge and mass transport, and photoelectrochemistry. Faculty and students in the EST program are drawn from a broad range of academic options, including materials science, chemistry, applied physics, chemical engineering, mechanical engineering, and environmental science and engineering. Areas of emphasis reflect this breadth of disciplines and include photovoltaics, photoelectrochemical cells, bio-fuels, fuel cells, batteries, thermoelectrics, hydrogen generation and storage, and nuclear energy. ENVIRONMENTAL SCIENCE AND ENGINEERING Research and teaching in the ESE program span the large scales of global climate variations, the local scales of urban air pollution, and the microscales of microbial ecosystems. Reflecting the interdisciplinary nature of the ESE program, it unites scientists and engineers from Caltech's Division of Geological and Planetary Sciences, Division of Engineering and Applied Science, and Division of Chemistry and Chemical Engineering. Jointly they address, for example, how climate has varied in the past and how it may change in the future, how biogeochemical cycles and chemical reactions control the composition of the atmosphere and local air quality as well as the Earth's global energy balance, and how more efficient and effective ways of producing biofuels or remediating toxic waste can be found. The methods employed in research projects include laboratory studies of fundamental chemical and biological processes; field studies of microbial ecology and of atmospheric chemistry; and computational and theoretical studies of chemical and physical processes on molecular to global scales. Environmental Science and Engineering 163 164 Students enter the ESE program with diverse backgrounds, from the basic sciences of physics, chemistry, and biology to applied science and engineering fields. The curriculum emphasizes interdisciplinary knowledge and is broad, yet it is flexible so that different backgrounds and focus areas can be accommodated. Areas of Research • Atmospheric Chemistry and Air Pollution. Atmospheric chemistry affects the composition of the atmosphere, properties of clouds, and local air quality. Research areas include cloud chemistry, aerosol chemistry and physics, trace gas photochemistry, and emission sources and transport and reaction pathways of organic species. The methods employed include laboratory studies of aerosol formation and of chemical reactions in the atmosphere; field campaigns with aircraft operated by ESE faculty; satellite missions carried out in collaboration with the Jet Propulsion Laboratory; and theoretical and modeling studies of tropospheric chemistry and the carbon cycle. • Environmental Chemistry and Technology. Environmental chemistry and technology research in ESE addresses fundamental questions in heterogeneous atmospheric chemistry (e.g., chemistry of clouds, fogs, and haze aerosols), in aquatic chemistry, in oxidation and reduction chemistry and technology, in semiconductor photocatalysis, and in hydrogen production from sunlight via electrochemical water splitting. • Dynamics of Climate. Climate dynamics research in ESE addresses fundamental questions about how Earth's climatic features are maintained, how they have varied in the past, and how they may change in the future. Research includes the large-scale dynamics of the atmosphere and oceans, the hydrologic cycle and how it responds to climate changes, monsoon dynamics, and the dynamics of the Southern Ocean, and climates of other planets. Methods employed include theoretical and modeling studies, analyses of observational data, and field campaigns to collect oceanographic data. • Biogeochemistry and Climates of the Past. Biogeochemical research in ESE finds application at scales ranging from microbial ecosystems to the global carbon cycle. Current research interests include the marine carbon cycle and its geochemical record in organic matter and carbonate minerals; microbial recycling of nutrients and carbon; and development and use of geochemical proxies for understanding the ancient environment, including its climate. Environmental Microbiology. Microorganisms are the primary drivers of global biogeochemical cycles and represent the most abundant and diverse forms of life on Earth. They catalyze critical biological transformation processes such as nitrogen fixation, oceanic primary productivity, and methane cycling. Microbial ecosystem research within ESE is focused on understanding microbial processes in terrestrial, marine, and extreme ecosystems. Research areas span a range of topics and field Areas of Study and Research sites, including the study of lignocellulose degradation by termite gut microbiota, anaerobic cycling of carbon, nitrogen, and sulfur in microbial mats and sediments, and methane cycling in the ocean. Physical Facilities ESE laboratories and facilities are housed in the Linde + Robinson Laboratory for Global Environmental Science and in other nearby buildings of Caltech's Division of Geological and Planetary Sciences. The laboratories are equipped with a wide variety of state-of-the-art instruments. • The Environmental Analysis Center (EAC) houses analytical instrumentation, for research that ranges from analyzing pollutants in groundwater to dating fossils. Its equipment includes instruments for electrochemistry, plasma emission mass spectrophotometry, gas chromatography, high-performance liquid chromatography, fluorescence spectroscopy, infrared spectrometry, gas chromatography-mass spectrometry, total organic carbon analysis, and electrophoresis and electrical particle size analysis. Scientists from across the Institute use the EAC for cutting-edge analytical studies. The Atmospheric Chemistry and Aerosol Laboratory is designed for studies of the photochemical reactions of gaseous and particulate pollutants. In two reaction chambers (28 m 3 each) — the first of their kind when they were built — the chemical reactions that produce urban smog and atmospheric particles are investigated under precisely controllable conditions. They have revealed how the particles that make up smog form in the atmosphere. Research results obtained with them have been instrumental in designing effective air quality policies. They continue to be invaluable in studies of air pollution. The High-Precision Spectroscopy Laboratory is housed in a quiet room- a room with specially designed acoustic and electromagnetic insulation. Acoustic foam blocks sound waves and copper cladding around the entire room blocks electromagnetic waves. The noise-free environment allows us to achieve exquisite precision in laser measurements of radiative properties of greenhouse gases, aerosols, and atmospheric trace constituents: the properties of single molecules can be measured. The measurements are the basis for climate models and for planning satellite missions to measure the composition of the atmosphere from space. In the Laboratory for Atmospheric Chemical Physics, the interactions of light with molecules in the atmosphere are investigated to elucidate how pollution forms and to measure the atmospheric concentration of aerosols and greenhouse gases. Techniques are developed for the global monitoring of the atmosphere from mobile ground-based laboratories and from space-based instruments. Environmental Science and Engineering 165 166 • In the Environmental Chemistry and Technology Laboratory, collimated sunlight from the Linde + Robinson solar telescope is focused into photolysis reactors, where artificial photosynthesis processes are developed to convert water and carbon dioxide into energetic fuels. Additionally, the chemical nature of the air-water interface is studied, and new technologies are developed for storing electric energy in novel lithium-air batteries and for treating water, for example, by photovoltaically powered electrolysis or ultrasonically induced cavitation. • The Geochemistry Clean Room is designed for trace metal analysis in an entirely metal-free environment. It has air cleansed of almost all particles, to be able to measure with high precision tiny traces of metals and radioactive isotopes found in ocean water and embedded in corals and in stalagmites. These measurements reveal information about how climate has varied in Earth's past and how carbon cycles between the biosphere, the atmosphere, and the oceans. The Clean Room is supported by a plasma mass spectrometry instrument room that contains two multi-collector instruments and a quadrapole instrument. The facility also contains a wet chemistry laboratory for the processing and analysis of environmental samples. • The Biogeochemistry Laboratories provide capabilities for analyzing the structure, abundance, and isotopic composition of organic materials in environmental samples, ranging from organisms to sediments to rocks. Instrumentation includes gas chromatograph-mass spectrometers, isotope-ratio mass spectrometers with capabilities for bulk and compound-specific analysis, a spectroscopic water isotope analyzer, and a combustion elemental analyzer. • In the Environmental Microbiology Laboratories, the diversity and metabolic activities of microorganisms from terrestrial and marine ecosystems are characterized through cultivation, microscopic imaging, metagenomics, and molecular and isotopic analysis. Instrumentation includes anaerobic chambers, platforms for performing microfluidics-based analyses of the nucleic acid contents of environmental single cells, capillary sequencers, quantitative PCR, epifluorescence microscopes, and CAMECA secondary ion mass spectrometers (7f Geo and nanoSIMS 50L) available through the Center for Microanalysis. • Fram High Performance Computing (HPC) Cluster. Fram is a (HPC) Cluster composed of 314 HP SL390 computer nodes with 12 cores available per node. The cluster is connected with a low latency, high bandwidth network called InfiniBand. In addition to the traditional computer nodes, it also has 60 GPU based nodes with a total of 180 Nvidia M2090 GPUs. This filesystem can perform at around 9.5 GB/s. Fram is the latest of many clusters used for analysis and simulation of climate dynamics. Additionally, Caltech collaborates with the Naval Postgraduate School's Center for Interdisciplinary Remotely Piloted Aircraft Studies (Monterey, California). This center operates research aircraft for Areas of Study and Research atmosphere science studies, including a Twin Otter aircraft that carries state-of-the-art instruments to measure atmospheric aerosol and cloud properties in situ. Faculty, students, and staff in the ESE program also have access to the supercomputer facility of the Division of Geological and Planetary Sciences, where they carry out simulations of dynamical processes in the atmosphere and oceans and of chemical reactions and transport processes affecting atmospheric chemistry. GEOLOGICAL AND PLANETARY SCIENCES Students and faculty in the Division of Geological and Planetary Sciences study Earth and the planets to understand their origin, constitution, and development, and the effect of the resulting physical and chemical environments on the history of life and on humanity. The approach to these problems relies strongly on the basic sciences. Programs of study and research are pursued in environmental science and engineering, geobiology, geochemistry, geology, geophysics, and planetary science. The curriculum is flexible so that students with degrees in biology, chemistry, engineering, or physics may carry out graduate work within the division, and interdisciplinary studies are encouraged. Southern California provides an excellent natural laboratory for the study of geology, tectonics, and earthquakes. Current advances in understanding the dynamic motions of Earth's interior have opened new opportunities for the study of crustal motions and earthquakes. Historic records of seismic activity are put into long- term perspective by studies of surface and bedrock geology. The dynamics and geometry of crustal movements are studied on local, regional, and global scales in order to understand the evolution of continents, subduction zones, and mid-ocean ridges. The division maintains active field programs in diverse areas in North America and throughout the world. The events that shaped Earth can be identified by studying the structure of rocks and their chemical and isotopic compositions. The absolute chronology of Earth and solar system history can be established by measurements of radioactive isotopes. These geological events have been intimately associated with the origin and evolution of life on Earth. The field of geobiology uses both geological and genetic evidence to examine the impact of life on Earth and the impact of geological conditions on biology. The field of geochemistry includes studies of radiogenic and stable isotopes, petrology, chemical oceanography, and atmospheric chemistry. These tools are applied to the origins of igneous and metamorphic rocks, evidence of past climate change, tracing anthropogenic influences on Earth, and the structure of planetary interiors. The comparative study of the other planets- their atmospheres, surfaces, and internal structures - is important in our understanding of Earth and its place in the cosmos. The early history of the solar system can be approached by studies of extraterrestrial materials, including lunar samples, interplanetary dust Geological and Planetary Sciences 167 168 grains, and meteorites. Physical Facilities The division is housed in four adjacent buildings, which are well equipped for modern instruction and laboratory work. They contain several seminar rooms and a library as well as student and faculty offices. Numerous computers are distributed throughout the division, including a facility for geographic information systems and remote sensing. Rock and mineral collections and sample preparation areas are available. There are modern laboratories equipped with a scanning electron microscope and electron microprobe; a variety of plasma-source, gas-source, thermal emission, and secondary ion mass spectrometers; optical-, infrared-, and Raman spectrometers; high-temperature furnaces and high-pressure apparatus including piston-cylinder, multi-anvil, diamond anvil, and shock-wave facilities. Cooperation with other departments on campus provides access to additional instrumentation for sample preparation and analysis. Laboratories for molecular geobiology provide capabilities for culturing, manipulating, and studying a wide range of environmental microbes, including anaerobes. A sensitive magnetometer facility is designed for the study of both biomagnetism and paleomagnetics. The Seismological Laboratory, housed in the GPS division, operates the Southern California Seismic Network jointly with the U.S. Geological Survey. The network records and analyzes real-time earthquake data from more than 380 seismic stations located across Southern California. Data from the network are available for research via the Southern California Earthquake Data Center. The Jet Propulsion Laboratory, NASA's lead center for planetary exploration, is located seven miles from campus and is administered by the Institute. Students and faculty participate in JPL activities through joint research, instrument development, mission operations, and data analysis. In addition, Caltech owns and operates several optical and radio observatories that are used partly for planetary research. Active programs of planetary studies are pursued at the Owens Valley Radio Observatory, Palomar Mountain, and the Keck Telescopes and, in the near future, the Thirty-Meter Telescope project. HISTORY AND PHILOSOPHY OF SCIENCE The program in history and philosophy of science is devoted to the study of the historical evolution and philosophical underpinnings of the physical and biological sciences. Work in history and philosophy of science may be pursued as an undergraduate option, a graduate minor, or on a course-by-course basis. Historical research in the program includes the origins of experimental practice, the social and institutional contexts of science, the origins and applications of quantitative methods, specific developments since antiquity in physics, biology, and chemistry, as well as biographical and comparative studies. Philosophical research in the program deals with issues in causation, explanation, scientific inference, the foundations Areas of Study and Research of probability and decision theory, philosophy of mind, psychology and neuroscience, and scientific fraud and misconduct. HUMANITIES English at Caltech spans the major periods of American and British writing. Students can pursue interests ranging from Shakespeare and a survey of drama to romantic and modern poetry; from early fiction to the postmodern novel. History at Caltech examines the Western and non-Western past to understand the evolution of culture, science, institutions, and behavior. Courses span the medieval, Renaissance, and modern periods; the United States, Europe, and Asia; and special topics such as radicalism and demography. In certain courses, quantitative methods drawn from the social sciences are applied to historical studies. Philosophy is concerned with the most fundamental issues involving the nature of the world and of human knowledge, values, and judgment. At Caltech, particular emphasis is placed on philosophy of the natural and social sciences, scientific inference, and philosophy of mind, psychology and neuroscience. In addition to survey courses we offer courses on more focused topics, including causality, probability, quantum mechanics, space-time, free will, consciousness, and on ethical questions raised by modern science and technology. Visual culture at Caltech encompasses the study of art history, film, media, and scientific images. Students work to gain visual literacy, and to understand both the history of images humans may have been looking at for hundreds or even thousands of years, and the provenance, location, and nature of the images we see now in our every day lives. Some visual culture classes make use of the resources of the Huntington Library, Art Museum, and Botanical Gardens; the Los Angeles County Museum of Art; and other museums in the area. Courses in English, history, philosophy, and visual culture are given at both introductory and advanced levels. A variety of courses in music, writing, and in foreign languages, literature, and culture are also available. Areas of Research The English faculty, interested in new approaches to studying their subject, engage in research into the relationships between literature and the pictorial arts, literature, and history, and the material production of literature. Research in history covers a wide range of historical fields and methodologies. Topics include an examination of the development of racial attitudes and behavior in the 19th-century United States; the history of the physical and biological sciences and of science in relationship to society; history and film; and political and economic development in early modern Europe. A number of faculty carry out research and teaching in the interrelated subjects of science, ethics, and public policy. Humanities 169 170 Research in philosophy includes work in philosophy of science and philosophy of mind, with particular research foci in philosophy of physics, causation, probability and decision theory, and the philosophy of neuroscience and free will. Faculty research in visual culture focuses on a wide variety of time periods, geographic locations, and media forms but has in common a careful attention to the conditions under which objects are made, the ways in which they circulate, and the reactions they inspire in audiences. INFORMATION AND DATA SCIENCES The information and data sciences are concerned with the acquisition, storage, communication, processing, and analysis of data. These intellectual activities have a long history, and Caltech has traditionally occupied a position of strength with faculty spread out across applied mathematics, electrical engineering, computer science, mathematics, physics, astronomy, economics, and many others disciplines. In the last decade, there has been a rapid increase in the rate at which data are acquired, with the objective of extracting actionable knowledge-in the form of scientific models and predictions, business decisions, and public policies. From a technological perspective, this rapid increase in the availability of data creates numerous challenges in acquisition, storage, and subsequent analysis. More fundamentally, humans cannot deal with such a volume of data directly, and it is increasingly essential that we automate the pipeline of information processing and analysis. All areas of human endeavor are affected: science, medicine, engineering, manufacturing, logistics, the media, entertainment. The range of scenarios that concern a scientist in this domain are very broad-from situations in which the available data are nearly infinite (big data), to those in which the data are sparse and precious; from situations in which computation is, for all practical purposes, an infinite resource to those in which it is critical to respond rapidly and computation must thus be treated as a precious resource; from situations in which the data are all available at once to those in which they are presented as a stream. As such, the information and data sciences now draw not just upon traditional areas spanning computer science, applied mathematics, and electrical engineering - signal processing, information and communication theory, control and decision theory, probability and statistics, algorithms— but also a range of new contemporary topics such as machine learning, network science, distributed systems, and neuroscience. The result is an area that is new, fundamentally different from related areas like computer science and statistics, and that is crucial to modern applications in the physical sciences, social sciences, and engineering. The Information and Data Sciences (IDS) option is unabashedly mathematical, focusing on the foundations of the information and data sciences, across its roots in probability, statistics, linear algebra, and signal processing. These fields all contribute crucial components of Areas of Study and Research data science today. Further, it takes advantage of the interdisciplinary nature of Caltech by including a required set of application courses where students will learn about how data touches science and engineering broadly. The flexibility provided by this sequence allows students to see data science in action in biology, economics, chemistry, and beyond. In addition to a major, the IDS option offers a minor that focuses on the mathematical foundations of the information and data sciences but recognizes the fact that many students in other majors across campus have a need to supplement their options with practical training in data science. INFORMATION SCIENCE AND TECHNOLOGY Information science and technology (IST) is a multidivisional research area that includes participants from the biology, chemistry and chemical engineering, engineering and applied science, humanities and social sciences, and physics, mathematics and astronomy divisions. Areas of emphasis include networking and distributed systems, neuromorphic engineering and sensory-based machines, quantum computation and communications, molecular electronics and biochemical computing, biological circuit design, information flow in economic and social systems, and mathematical foundations of information. Physical Facilities IST is mainly centered around the Annenberg Center for Information Science and Technology and the Moore Laboratory. Research centers associated with IST include the Lee Center for Advanced Networking, the Center for Neuromorphic Systems Engineering, the Center for Biological Circuit Design, the Center for the Mathematics of Information, the Center for the Physics of Information, and the Social and Information Science Laboratory. INTERDISCIPLINARY STUDIES PROGRAM Interdisciplinary studies offer an educational alternative for undergraduates whose goals cannot be satisfied with a normal undergraduate option. The student gathers a two-person faculty committee, representing at least two divisions of the Institute, and chooses their own scholastic requirements under this committee's supervision. Approval must also be obtained from the Curriculum Committee, a standing committee of the faculty. The interdisciplinary studies program has no facilities of its own. Areas of study and research may be selected from any part of the Institute. (For a complete description, see Interdisciplinary Studies Program.) Interdisciplinary Studies Program 171 172 MATERIALS SCIENCE Materials scientists study relationships between the properties of materials and their internal structure, and how this structure can be controlled. Our multidisciplinary faculty, students, and postdoctoral scholars create new materials and take rigorous approaches to understand and control the properties of materials and their internal structure. From batteries and solar cells, to electronic devices at the micro- and nano-scales, our department is at the forefront of scientific discovery and new technologies. Areas of Research The current areas of research by the materials science faculty include a broad range of materials, some far removed from their equilibrium thermodynamic states. Examples of such materials include metallic glasses, thin films, two-dimensional solids, quantum materials, porous and architected solids, energy-storage materials, nanostructured materials, and materials for photovoltaics and electronic devices. The physical characteristics of interest span a wide range of mechanical, thermodynamic, electrical, magnetic and electrochemical properties. Physical Facilities Research by the faculty, graduate students, and advanced undergraduates is conducted in the W. M. Keck Laboratory, the Harry G. Steele Laboratory, and frequently in the Kavli Nanoscience Institute (KNI) Laboratory, a core cleanroom facility dedicated to nanofabrication and characterization. The KNI Lab and its technical staff provide training and access to advanced instrumentation that support the nano- and microfabrication process from beginning to end. This includes resources for electron and ion beam lithography; optical lithography; thin-film and chemical vapor deposition; metal and oxide evaporation; dry etching; metrology including a spectroscopic ellipsometer; a suite of microscopes, such as focused ion beams (FIB), scanning electron microscopes (SEM) with energy dispersive spectroscopy, and AFM. The KNI also manages a transmission electron microscopy (TEM) facility which houses a 300-keV scanning TEM instrument with high resolution and analytical capabilities. Additional facilities for the characterization of materials include X-ray powder diffractometers with position-sensitive detectors. Material-preparation facilities include equipment for additive manufacturing, physical vapor deposition under ultra-high vacuum conditions, arc melting, induction melting, casting, rapid solidification, processing of ceramic powders, and high-energy ball milling. More specialized instruments include impedance spectrometers for transport and dielectric measurements, Mössbauer spectrometers, differential scanning calorimeters and differential thermal analyzers, thermogravimetric analyzers, and gas adsorption analyzers. In addition to the general-use equipment within materials science, a wide range of mechanical and microstructural characterization facilities are available elsewhere at Caltech including a scanning electron microscope with electron backscatter detectors, an electron Areas of Study and Research probe micro-analyzer, mechanical testing machines, nanoindenters, an in-situ mechanical deformation instrument, AFM, electrochemical instrumentation, and an electrical probe tester.

In addition to offices for the faculty and graduate students, there are classrooms, conference rooms, discussion areas, a lecture hall, and a lounge for informal gatherings of the students and staff. The mathematics collection is housed nearby in the Sherman Fairchild Library. MECHANICAL ENGINEERING Mechanical engineering at Caltech explores the boundaries between traditional disciplines of science and engineering in order to develop a fundamental understanding of interdisciplinary challenges and create advanced technology to address contemporary problems. Mechanical engineering encompasses three broad areas: (1) mechanics of Mechanical Engineering 173 174 materials, (2) systems and control, and (3) thermal sciences and fluid dynamics. The educational program in mechanical engineering prepares students for research and professional practice in an era of rapidly advancing technology. It combines a strong background in the basic and engineering sciences with anemphasis on addressing the critical technological challenges of the day. It strives to develop professional independence, creativity, leadership, and the capacity for continuing professional and intellectual growth. Areas of Research • Mechanics of Materials. Studies in the field of mechanics of materials emphasize a fundamental understanding of mechanical behavior and failure of materials as well as its applications. Areas of interest include static and dynamic deformation and failure of homogeneous and heterogeneous solids, mechanical behavior of nanostructures, active materials, microstructure characterization and evolution, thin films, micro-electro-mechanical systems (MEMS), composites, fracture and frictional sliding of solids, earthquake source processes, seismo-mechanics, geomechanics, and granular media. Most problems emphasize bridging temporal and spatial scales and the development of advanced analytical, computational, or experimental techniques. • Systems and Control. This area combines a broad range of mechanical engineering fields, including control systems, dynamics, kinematics, and mechanical design, as well as cross-disciplinary areas such as signal processing, computer control, engineering computation, electromechanical design, micro-electro-mechanical systems (MEMS) design, and bioengineering. General areas of interest include control theory, estimation theory, decision theory, and robotics. • Thermal Sciences and Fluid Dynamics. This area encompasses experimental and computational research in fluid dynamics, heat and mass transfer, thermodynamics, and combustion. Specific research areas include Stokesian dynamics, granular materials, cavitation and multiphase flow, turbulent combustion, explosion dynamics, and flow-generated sound. Applications cover a range of scales from molecular to high Reynolds number flows. They include constitutive modeling of colloidal dispersions, micro/nanofluidic systems including Marangoni and thermocapillary forcing in thin liquid films, the formation of pollutants from combustion hydrocarbon fuels, instabilities of complex, reacting flows, and high-speed flows with shock waves. Inter-disciplinary activities in the group include research on geophysical phenomena, biomedical devices, bio-inspired propulsion, and application of control theory to fluid mechanics. Areas of Study and Research Physical Facilities Students and faculty in mechanical engineering conduct research in laboratory facilities in a number of areas, including design and prototyping, flow visualization, heat transfer, robotics, bio/nano-mechanics, nano-mechanical testing, seismo-mechanics, biomolecular circuits, autonomous vehicles, explosion dynamics, T5 hypervelocity flow, and geomechanics. A number of High Performance Computing (HPC) clusters are available, including both CPU- and GPU-based architectures. Kavli Nanoscience Institute (KNI) is utilized for micro- and nano-fabrication, testing, and characterization. The Jim Hall Design Lab (The Lab) is a 5,000-square-foot machine shop and maker space facility available to students, faculty, and staff of the Caltech Community. The lab facility trains students on various tools and machines ranging from conventional manual devices, such as lathes and mills, to the most modern technologies, including computer numerically controlled (CNC) Mills, Lathes, Laser, and Water Jets cutters, and 3D printers. The physical workspace and its full suite of tools enable students to formulate and draft engineering concepts using computer-aided design (CAD) software and assemble actual working prototypes from metals, plastics, and the latest in high-strength composites. As engineers in training, our students' lab experience provides a "hands-on" aspect to their educational background, complementing their foundational engineering coursework. The mission of our lab facility is to enable our students to gain valuable technical and project management experience and prepare them for the next phase of their careers. The undergraduate lab facility is a state-of-the-art, 950-square-foot teaching laboratory located in the Gates-Thomas building. The lab space contains an axial-torsional (25kN) material test frame, strain gage measurement system, air-isolated optical table, and 2D Digital Image Correlation (DIC) optical metrology for full-field 2D visualization and quantification of mechanical deformation and strain in engineering materials. The lab facility also includes a 20 cm x 2cm x 2m water tunnel with an integrated laser particle image velocimetry (PIV) system for full-field visualization of 2D velocity flow fields. The primary mission of this lab facility is to support the Experiments and Modeling in Mechanical Engineering (ME50a/b) course sequence, which is offered each year during the winter and spring quarters. ME50a, taken during the winter term, introduces our students to Computational Fluid Dynamics (CFD) and experimental fluid mechanics. ME50b, taken during the spring term, introduces our students to Finite Element Analysis (FEA) of engineering structures and experimental solid mechanics. Students gain hands-on experience in both parts of the course sequence as they work through each phase of a lab experiment, data collection, and post-processing of the experimental through Matlab. Technical writing skills are also reinforced through individual reports that students must independently draft and submit for each modeling assignment and lab project.

MICROBIOLOGY Microbiology recognizes that microbial inventions have profoundly shaped every aspect of the biosphere and geosphere throughout Earth's history. Many important molecular and cellular processes in eukaryotes are now known to have first arisen in bacteria and archaea, and microbial metabolic activities control numerous geochemical cycles. Microorganisms have served and will continue to serve as model systems in many areas of science, ranging from basic biology and biochemistry, to the understanding of physical principles governing biological systems, to emerging questions of robustness, stability, and design in complex networks. Interactions among microbes within communities, as well as interactions between microbial communities and their environments, are poorly understood. Yet studying these interactions is key to understanding fundamental relationships in nature, such as: 1) the feedback loops connecting microbial activities in aquatic or terrestrial habitats with changes in composition of the atmosphere, hydrosphere and geosphere, and 2) the symbiotic associations that sustain diverse forms of life today. For example, the interactions between a mammalian host and its microbiota are essential to the host's normal functioning and development, not merely the cause of infectious disease. Due to their metabolic versatility, microorganisms are likely to emerge as key engineering components for solving global societal problems, ranging from human health, to energy, to providing clean water to more than one billion people who currently live without it. Caltech's version of microbiology is unique. Diverse faculty from four divisions (BBE, CCE, GPS, EAS) work together to train students in how to understand microbial systems at various spatial and temporal scales: from the molecular to the global, from the present to the past. This interdisciplinary training involves study of molecular and cellular biology, physiology, chemistry, ecology, and quantitative reasoning. Microbiology 177 178 NEUROBIOLOGY Understanding the brain remains one of the great intellectual challenges for science. To grasp the function of this marvelous organ, one needs to investigate structures, mechanisms, and dynamics that span across many spatial and temporal scales. For example, when we hear a sound, our brain is sensitive to time delays of just a few microseconds, yet the memory of that sound can last a lifetime- 11 orders of magnitude longer. The span is similar in the spatial domain. The sheer number of nerve cells in the brain, approximately 1,011, suggests a coarse-grained treatment that glosses over the details of the individual neurons, yet a single nerve cell and even a single molecule can play a decisive role. For example, activation of a single light receptor in our eye leads to a visual percept that can ultimately direct our behavior. Neurobiology at Caltech does, indeed, span this range. Our laboratories work on the molecular structure and function of channels and receptors; the integration of such molecules into signaling organelles like the synapse; the structure and function of single neurons; the integration of neurons of diverse types into circuits; and the collective function of these circuits in controlling behavior, perception, memory, action, cognition, and emotion. Another area of emphasis concerns the developmental mechanisms by which these structures form: the differentiation of neurons in early life, the genetic mechanisms that guide their synaptic wiring plan, and how subsequent experience modifies these connections. There is also increasing interest in leveraging the basic neurobiological insights to an understanding of brain disorders. Finally, Caltech's traditional strength in engineering stimulates the development of new methods for brain science: from optical techniques to new twists of genetic engineering, to novel multi-electrode devices, to computational models and theories.

PHYSICS Areas of Research Students in physics will find opportunities for research in a number of areas where members of the faculty are currently active, including those listed below. Physics research at Caltech is often done in collaboration with scientists in the departments of applied physics, astrophysics, planetary science, engineering, chemistry, biology, and other departments, as well as with collaborators at other universities and laboratories. Additional research programs and more detailed information can be found on the Caltech physics department website. • Experimental Elementary Particle Physics. Activities in elementary particle physics are aimed primarily at discovering new particles Areas of Study and Research and interactions physics beyond the Standard Model (BSM) complemented by precision measurements of SM processes. Experimental efforts employ hadronic colliders and electron, muon, and neutrino beams at several international facilities. Current experiments include: • CMS searching for dark matter and other new particles and new symmetries up to the mass scale of several TeV at the Large Hadron Collider at CERN • the NOvA and DUNE long baseline experiments at Fermilab, studying the pattern of masses, mixing and CP violation in the neutrino sector • the Mu2e experiment, searching for physics beyond the standard model in charged lepton flavor violation • a nascent effort to search for accelerator production of dark matter called LDMX • the long-running SuperCMS effort to directly detect scattering of galactic dark matter with normal matter. • Theoretical Elementary Particle Physics. The particle theory group studies the unification of interactions based on string theory, the detailed properties of hadrons described by QCD, the quantum properties of black holes, the foundations of cosmology, including dark matter and dark energy, and other aspects of mathematical physics. Condensed-Matter Physics. Areas of interest include correlated electron systems, topological quantum matter, quantum dynamics, disordered systems, phase transitions, atomic and excitonic Bose condensation, nanomechanical and nanoelectronic systems, biosensors, quantum electromechanics, phonon physics, high-temperature superconductivity, graphene and carbon nanotube systems, quantum entanglement, dynamics of disordered systems, chaos, pattern formation, and systems far from equilibrium. Resources include numerous labs in the Caltech physics department, at the Kavli Nanoscience Institute at Caltech, and at the Jet Propulsion Laboratory. • Quantum Optics and Information. Research on campus and at the Institute for Quantum Information and Matter at Caltech includes studies of the nature of quantum computation and quantum information, cavity quantum electrodynamics, algorithms and error correction techniques in quantum computation, and generally how quantum physics can be harnessed to improve the acquisition, transmission, and processing of information. • Experimental Atomic/Molecular/Optical Physics. Experimental atomic, molecular, and optical (AMO) research at Caltech focuses on controlling and understanding complex quantum systems for a wide variety of scientific goals. Current experiments include building arrays of ultracold atoms to study quantum information, metrology, many-body physics, and simulation of condensed matter systems; precision measurements in cold and ultracold polar molecules to search for fundamental symmetry violations; engineering atom-light interactions in photonic crystals; quantum Physics 179 180 physics of mechanical devices, hybrid superconducting quantum circuits, and optomechanical sensors; neurophotonics and neuromolecular sensing; development of quantum networks and communication and addressing fundamental questions in quantum information. Many of these research strands are collaborative efforts supported by the Institute for Quantum Information and Matter. • Nuclear Physics. The interests of the nuclear group focus on performing precision measurements to search for new physics beyond the Standard Model. In particular, precision measurements of free neutron decay allow sensitive searches for new physics, while measurements of the neutron electric dipole moment may help explain the dominance of matter over antimatter in the universe. • Astrophysics. Research in this area covers a broad range of topics using observational tools covering the entire electromagnetic spectrum. The high-energy astrophysics group at the Space Radiation Laboratory (SRL) uses X-ray and gamma-ray detectors aboard spacecraft and balloons to investigate energetic processes from compact astrophysical objects, including gamma-ray bursts from neutron-star and black-hole systems, supernova and hypernova dynamics, and the development of stars and galaxies in the early universe. • The cosmic ray group at SRL uses data from a variety of spacecraft to study the composition of energetic particles arriving from the sun, the local interstellar medium, and beyond, in order to understand the origin and acceleration of energetic particles in space. • The millimeter/submillimeter astronomy group, with collaborators at the Jet Propulsion Laboratory, studies the solar system, star and planet formation, the interstellar medium, galaxies, galaxy clusters, and the epoch of reionization using data from the Caltech Submillimeter Observatory (CSO) and other facilities. Future-oriented programs include the development of new superconducting detector technologies and instruments for use at these wavelengths, also in collaboration with JPL, and an effort to move the currently idle CSO to a new, more sensitive site. The Galactic compact objects astrophysics group studies black holes, neutron stars, and white dwarf systems, including gravitational wave sources detectable by future space missions such as LISA. The group uses telescopes at Palomar, Kitt Peak and the Keck Observatory, as well as the radio telescopes of the NASA Deep Space Network. • Theoretical Astrophysics. The TAPIR (Theoretical Astrophysics Including Relativity) group carries out research on an ever-changing list of topics, including planets; stars, neutron stars, black holes and their interactions; gravitational-wave astrophysics; cosmology; the formation of stars and galaxies; and numerical and analytical general relativity. Areas of Study and Research • Cosmology. The observational cosmology group explores the structure and dynamics of the early universe using precise measurements of the cosmological microwave background radiation and large scale structures from detectors on the ground, on balloons, and on spacecraft. Efforts to directly detect dark matter are also underway. These experiments include an active program of detector development in collaboration with scientists at the Jet Propulsion Laboratory. Theoretical studies seek to understand the large-scale structure of the universe, including the physical nature of dark matter and dark energy. • Gravitational-wave Astronomy. Observations from the (current) LIGO and (future) LISA projects are used to detect and analyze gravitational radiation to study a variety of astrophysical sources. Theoretical studies are aimed at developing sensitive data analysis techniques and calculating gravitational-wave signals from sources such as coalescing black holes and neutron stars. Physical Facilities The physics and astrophysics departments and laboratories are mainly housed in six buildings on campus: the Norman Bridge Laboratory, the Alfred P. Sloan Laboratory of Mathematics and Physics, the W. K. Kellogg Radiation Laboratory, the George W. Downs Laboratory of Physics, the C. C. Lauritsen Laboratory of High Energy Physics, and the Cahill Center for Astronomy and Astrophysics. Off-campus astronomical facilities include Palomar Observatory, the Keck Observatories, Owens Valley Radio Observatory, the Caltech Submillimeter Observatory (currently idle), and the Laser Interferometer Gravitational-wave Observatory (LIGO). SCIENTIFIC AND ENGINEERING COMMUNICATION The Engineering and Applied Science (EAS) Division offers a program of study in Scientific and Engineering Communication that prepares students to engage with a variety of audiences and effectively communicate scientific topics. In order for engineering graduates to excel in their chosen field, they need to develop oral, written, and media communication skills, and an ability to work with a variety of stakeholders including industry leaders, policymakers, and academics. Courses in Scientific and Engineering Communication (SEC) provide opportunities for students to experiment with a variety of communication genres and in diverse environments. The program is characterized by cross-disciplinary study and authentic practical experiences in scientific communication and advocacy. Scientific and Engineering Communication 181 182 SOCIAL AND DECISION NEUROSCIENCE The Institute offers an interdisciplinary program of study in Social and Decision Neuroscience that prepares students to conduct research on the neurocomputational basis of decision-making and social interactions. In order to carry out cutting-edge research in this area, students need to acquire in-depth understanding of computational modeling, statistical methods, systems neuroscience, neural measuring methods such as MRI, EEG or single unit recordings, as well as adequate understanding of related methods and results from the social sciences. The program is designed for students seeking faculty jobs in neuroscience, psychology, marketing, economics, political science or finance, or industry positions in the technology, data science, and finance fields. Areas of Research This program is characterized by interdisciplinary research at the frontier of neuroscience, psychology, economics, and political science. Examples of research topics of interest include the following: • Computational and neurobiological foundations of simple choice in animals and humans. • Computational and neurobiological basis of economic and political decision making. • Neurocomputational basis of emotion and the impact on cognition and behavior. • Neurobiological basis of social behavior in human and animal models. • Neurobiological basis of moral judgment and decision-making. • Applications of neuroscience to economics, finance, and political science. Physical Facilities Research is conducted in multiple laboratories spanning a wide range of experimental techniques - from behavioral experiments to single unit neurophysiology. Researchers also have access to two state-of-the-art facilities: the Caltech Brain Imaging Center, which contains various human and animal brain scanners, and the Social Science Experimental Laboratory, which contains state-of-the-art facilities for conducting behavioral economic experiments of group and market interactions. Areas of Study and Research SOCIAL SCIENCE PHILOSOPHY AND GOALS OF THE SOCIAL SCIENCE UNDERGRADUATE CORE The social science core curriculum initiates students in the study of how humans organize, decide, govern, and allocate their resources. It teaches students how to analyze and reason about individual behavior, markets, and other institutions. Our curriculum covers methods, as well as substance. The issues facing our students in the future will be different from those that are current, but the analytical principles and methodology needed to understand those problems will likely remain the same, albeit improved. Thus, the social science core curriculum provides students with the knowledge and tools to, in the words of the catalog, "navigate the societal, political, and economic factors that influence, and are influenced by, their work." The objectives of the social science core curriculum can be broken into three broad categories of courses: introductory courses that teach basic principles; methods courses that seek to transmit skills and analytical tools; and courses exposing students to substantive ideas and problems in the social sciences. More concretely: "Fundamental ideas and principles" classes expose students to a broad and introductory overview of basic ideas in anthropology, economics, psychology, and political science. "Methodology and analysis" courses focus mainly on giving students the theoretical and empirical tools to analyze problems. They cover the theoretical modeling tools most commonly used in the social sciences, as well as statistical and econometric techniques that are needed to analyze data. "Substantive problems in social science: Individuals, institutions, and markets" courses expose students to an array of substantive questions in social science, from resource allocation via markets and prices, the workings of political institutions, the consequences of poor governance, the psychological basis of human behavior, and an understanding of financial markets. SOCIAL SCIENCE GRADUATE PROGRAM The Caltech Ph.D. program in Social Science is highly interdisciplinary, integrating economics, political science, quantitative history, econometrics, and finance. It makes extensive use of mathematical modeling, laboratory experiments, and econometric techniques. Research in the social sciences program at Caltech strongly emphasizes the under-standing and analysis of the relationships between individual incentives, collective behavior, political and economic institutions, and public policy. Areas of Research • Experimental Economics and Experimental Political Science . Caltech social scientists were among the early pioneers in the field of laboratory experimentation and Caltech has maintained a strong leadership position and research presence in the field ever since. Examples of the kinds of laboratory studies the faculty are engaged in include the behavior and design of auctions and Social Science 183 184 market-like mechanisms, public goods provision and related topics in public economics, the economics of networks and matching, decision theory, inter-personal bargaining, behavioral economics, committee decision making, and electoral competition. Many of our faculty engage in laboratory experimentation as part of their research agendas in economics and political science (Agranov, Camerer, Echenique, Nielsen, Palfrey, Plott, Saito, Shum, Sprenger). Considerable laboratory experimentation also focuses upon the workings of financial markets, and seeks to elucidate basic principles that underlie the pricing of assets, trading, and information aggregation in these markets. Many of these experiments are conducted through the use of net-worked computers (see Facilities) in the William D. Hacker Social Science Experimental Laboratory (SSEL) and the Laboratory for Experimental Economics and Political Science (LEEPS). The real world provides another setting for experimental research outside the laboratory, and Caltech social scientists have conducted field experiments involving a wide variety of topics, ranging from decision making in organizations, social networks, and the behavior of different cultural groups ranging from college students, to urban Americans to African villagers. • Economic Theory and Game Theory. Caltech has a strong research group in economic theory, which, together with rigorous training in statistics and econometrics forms the backbone of the core curriculum for the PhD program. Theoretical research at Caltech has played a key role in the design and practical implementation of new institutions that more efficiently allocate scarce resources and provide public goods. Some of this work has had important public policy applications. Prominent examples include the design of FCC auctions to allocate the electromagnetic spectrum for telecommunication, and the market for allocating and trading permits for pollution emissions in the Los Angeles basin. Much of this theoretical design research is complemented by experimental studies that provide a testbed for competing designs. There is an active group of faculty and graduate students working in the areas of the optimal design of contracts and markets (Cvitanic, Echenique, Plott), the economics of information (Pomatto, Tamuz), decision theory (Echenique, Pomatto, Rangel, Saito), game theory (Echenique, Palfrey, Pomatto, Saito, Tamuz) and matching Social Science and Research (Echenique). There are several active programs for inter-action between our theory faculty in the social sciences and the faculties of computer science and applied mathematics. This is formally organized around two interdisciplinary centers, the Lee Center for Advanced Networking and the Social and Information Science Laboratory (SISL), with the latter offering a bi-weekly seminar coordinated between the computer science department and the social sciences faculty and featuring speakers in eco-nomics, computer science, game theory and related disciplines. There are many informal connections that reinforce the formal connections, including research collaborations Areas of Study and Research between faculty and graduate students in these different areas. • Political Economy and Political Science. Caltech has a long tradition of strength in research that spans the boundary of the economics and political science disciplines. Research in political economy at Caltech continues to be a major strength of the program and provides a natural bridge that unites the faculty in economics, political science, and quantitative history. The focus of research in political economy and political science at Caltech emphasizes rigorous theoretical modeling drawing heavily upon techniques from economic theory and game theory, combined with empirical studies using highly sophisticated quantitative analyses of a wide variety of data sources: experimental, survey, field, voting, and historical data. Ongoing political economy research areas of the current faculty include: the interacting forces of bargaining, voting, and communication in commit-tees, legislatures, bureaucracies, and assemblies (Agranov, Gibilisco, Hirsch, Katz, Lopez-Moctezuma, Palfrey, Plott); the Voting Technology Project, a joint Caltech-MIT research venture, established in 2000 to evaluate and improve the performance and reliability of U.S. balloting technology, registration systems, election administration, redistricting, and election law (Alvarez, Katz); political forces affecting judicial behavior (Hirsch, Shum), strategic voting in multicandidate and multi-stage elections (Alvarez, Kiewiet, Palfrey, Plott), the politics of inequality and redistribution (Agranov, Palfrey) and several areas of comparative and international politics, including studies of the causes and consequences of corruption, domestic unrest, and international conflict (Ensminger, Gibilisco, Lopez-Moctezuma) Financial Economics . Caltech has built a small but very active research group in finance. The researchers in this group are working on a range of topics in mathematical finance (Cvitanic), empirical studies of venture capital and entrepreneurship (Ewens), asset pricing (Cvitanic, Jin, Plott, Roll), dynamic contracting (Cvitanic), and behavioral finance (Camerer, Jin, Plott). There is a regular seminar series in finance that features distinguished researchers from around the world. Caltech faculty outside the finance group itself are also engaged in empirical research in financial economics. These include experimental Areas of Study and Research studies of asset markets (Camerer, Palfrey, Plott), interest rate policy making by the Federal Open Market Committee (Lopez-Moctezuma), and online credit markets (Xin). • Behavioral Economics. Research in behavioral economics at Caltech overlaps all of the above groups. Laboratory experimental research discovers interesting behavioral anomalies and can also test theoretical models designed to account for such anomalies. On the theoretical side, much of the game-theoretic and decision-theoretic research at Caltech is motivated by experimental observations, leading to extensions or modifications of standard models. These extensions in turn suggest experimental designs that are then implemented in the Social Science 185 186 laboratory by our faculty and graduate students. Faculty research in political behavior (Alvarez, Katz, Kiewiet) and behavioral finance (Camerer, Jin, Plott) are complementary and add strength more generally to under-standing social behavior. We also have on our faculty a small but very active group conducting research at the boundary of biology, psychology, and the social sciences (Adolphs, Camerer, Mobbs, O'Doherty, Rangel). This group offers a separate PhD option focused on the behavioral neuroscience of decision making (see the catalog entry for "Social and Decision Neuroscience"). Utilizing fMRI brain-imaging, eye-tracking, and other biological measurement technologies, this group, often in collaboration with other social science faculty and graduate students, has begun to explore the neural foundations of decision making in individual choice, game theoretic, and market settings. Quantitative History. Just as with the theoretical, experimental, and empirical work using contemporary, historical research conducted at Caltech employs mathematical modeling and sophisticated statistical techniques to attack a wide range of historical questions. Historical research conducted at Caltech addresses questions that cut across economics, political science, political economy, and even finance, often combining archival work with state-of-the art statistical techniques. These include the development of capital and credit markets in Europe (Hoffman, Rosenthal), the evolution of wealth distribution from 1800 to the present (Rosenthal), the causes of recurrent financial crises in capitalist economies (Hoffman, Rosenthal), and the determinants of economic and technological growth. • Applied microeconomics and econometrics. Empirical research in social science blends creative collection and analysis of field data with rigorous application of tools and methods from econometrics and statistics. We offer courses and supervise students in these areas. A number of faculty members specialize in empirical work in a number of fields, including finance (Ewens, Jin, Xin), industrial organization (Shum, Xin), political economy (Alvarez, Gibilisco, Katz, Kiewiet, Lopez-Moctezuma, Sherman, Shum), and behavioral economics (Camerer, Jin). Methodological areas of specialization include econometrics (Sherman, Shum, Xin), causal inference (Alvarez, Katz, Sherman, Shum), machine learning (Alvarez, Katz, Xin), and Bayesian statistics (Katz). Physical Facilities Caltech has two state-of-the-art onsite laboratories for experimental esearch in economics, political science, game theory, decisio heory, and financial economics: The Laboratory for Experimenta Economics and Political Science (LEEPS, established 1987) and The Hacker Social Science Experimental Laboratory (SSEL, established 1998). Areas of Study and Research SYSTEMS BIOLOGY Systems Biology seeks to understand how the parts of biological systems are integrated to produce the amazing machines, cells, organisms and ecosystems that exist in our world. We seek to define general principles of biological systems. Part of the effort involves defining the relevant parts and measuring how they change in a quantitative and comprehensive fashion as they carry out their functions. This task is the domain of genomics, proteomics, metabolomics, functional genomics, bioinformatics and other aspects of Network Biology and Bioinformatics. Another related task is to understand the "mechanisms," the precise structures and interactions of those parts that ultimately produce biological function. This task requires Computational Modeling of potential mechanisms, coupled with Quantitative tests of the predictions of models by cell biological, molecular biological, and biophysical techniques. One particularly stunning feature of organisms is their ability to develop trom a single fertilized egg; thus, Systems Developmental Biology is an important third theme of our program. This theme involves the study of how organisms generate complexity of cell types in a defined spatial organization by a sequential, contingent, irreversible cascade of molecular, cellular, and genomic processes. Our goal is to train students who can seamlessly integrate diverse quantitative and experimental methodology and can balance the tension between global understanding and mechanistic insight. This training involves study of biology, mathematics, quantitative reasoning, computational and data analysis tools, and the rich experimental methods of the biological sciences.

Restrictive Early Action applicants will be informed of their admissions decision in mid-December and Regular Decision applicants will be informed by mid-March. Regardless of round, admitted students have until May 1 to respond to their admissions offer. Gap Year Caltech will consider requests from admitted students for a one-year gap year. Students who request a gap year must accept their offer of admission and then submit a written request stating the purpose of postponement to the Director of Undergraduate Admissions. Advanced Placement, International Baccalaureate, and College Credit Caltech encourages all prospective undergraduate applicants to prepare by challenging themselves with the most rigorous course of study available, including the Advanced Placement (AP) and International Baccalaureate (IB) programs. However, college credit for AP or IB classes is not automatic. Course credit and/or placement in an accelerated program is sometimes granted as deemed appropriate by the department faculty. The awarding of Caltech course credit takes place at the time of registration each fall. Admission to the First-Year Class 191 192 Biology Biology majors who have passed Bi 8 and Bi 9 (with 9 units on grades) are considered to have met the core requirement of Bi 1. Chemistry The student's qualifications for placing out of Ch 1 ab will only be determined by the performance on a placement examination to be administered in the summer prior to registration. Qualified students, with the instructor's consent, are allowed to substitute either Ch 8 or Ch/ChE 9 for the "core" chemistry laboratory requirement (Ch 3 a or Ch 3x). English/Writing All incoming students (first-year and transfers) will take a placement assessment to determine whether they are adequately prepared for the substantial writing component that is part of all first-year humanities courses. Most new students participate in a web-based version of this assessment, which is usually conducted in early June. A makeup assessment is held just before fall classes begin. Based on results of this writing assessment, students may be required to take Wr 1 or Wr 2 in the fall quarter. (Wr 1 and Wr 2 count for general Institute credit only.) After completing these courses, students may, at the discretion of humanities faculty, be required to go on to subsequent coursework in academic writing, such as Wr 3, Wr 4, or Wr 50, before or concurrently with first-year humanities coursework. During the first week of classes, students will be required to produce an in-class writing sample to confirm the initial placement. Mathematics During the summer before the first year, entering first-year students are asked to take a diagnostic exam in basic calculus that will determine which students will be placed in a special section of Ma 1 a for those with less complete preparation, and later take Ma 1 d; and if they are interested in advanced placement, they may also take an examination to determine whether they will begin the mathematics core sequence at an advanced level. Normally, an entering first-year student takes Ma 1 abc, Calculus of One and Several Variables and Linear Algebra. This course covers the calculus of functions of one and several variables; infinite series; vector algebra; basic and advanced linear algebra; derivatives of vector functions, multiple integrals, line and path integrals; and theorems of Green and Stokes. The course is divided into a lecture part and a recitation part that focuses mainly on problem-solving. Students in need of additional problem-solving practice may be advised to take Ma 8 (in addition to Ma 1 a) in the first quarter. Physics The required first-year physics course, Ph 1 abc, is considerably more rigorous than most advanced placement work, and entering first-year students are encouraged to take Ph 1. A test is administered during the summer to aid in the organization of Ph 1; students who have performed particularly well can discuss the possibilities for advanced Information for Undergraduate Students placement with the physics representative during orientation. A second test may then be required. Residency Expectation Undergraduate housing includes the eight houses (Avery, Blacker, Dabney, Fleming, Lloyd, Page, Ricketts, Ruddock), and the Bechtel Residence and Marks House and Braun House. First- and second-year students are required to live on campus. Requests for exceptions to this requirement should be submitted to the Office of Residential Experience, and must be approved by the Dean of Undergraduate Students and the Vice President for Student Affairs. New Student Orientation All first-year, transfer, 3/2 and exchange students are expected to attend the New Student Orientation as part of the regular registration procedure. Orientation takes place the week prior to the beginning of classes. Faculty members, staff and upperclass student leaders participate help to introduce new students to the Caltech community. The orientation period provides an opportunity for new students to become acquainted with the campus, the Honor System, and other aspects of life at Caltech. In addition, they will meet classmates, upperclass students, and faculty during this time 193 ADMISSION TO UPPER CLASSES BY TRANSFER TRANSFER ADMISSIONS Caltech admits transfer students for the fall term only. We require a completed application, letters of recommendation, an official transcript from the last secondary school attended and all colleges or universities attended, descriptions of all college-level math and science courses, and completion of the Caltech Transfer Entrance Examinations. Please review the section titled "Eligibility Criteria for Admission" to determine whether you meet the eligibility requirements for transfer admissions consideration. Academic Preparation The following is a list of the Caltech core curriculum, taken by all Caltech students during their first two years. It is expected that transfer students will have had exposure to mathematics and science courses on a comparable level prior to entry to Caltech. Any of the following core courses that have not been covered by incoming transfer students must be taken upon matriculation to Caltech. There are no specific topics expected to have been covered in humanities and social science classes. An evaluation of each transfer student's written English is required prior to registration and may result in an additional course requirement. First-year courses: Admission to Upper Classes by Transfer 194 • Mathematics 1 abc • Physics 1 abc • Chemistry 1 ab • Chemistry 3 a or 3 x • Biology 1, 1 x, 8, or 9 • Humanities and Social Science electives • Menu science class (see Menu Classes; can be taken first-year or sophomore year) Sophomore courses: • Physics 2 abc or Physics 12 abc • Additional laboratory science • Humanities and Social Science electives Note: Mathematics 3 is not required for the core curriculum, but may be required for a specific option.] Eligibility Criteria for Admission The Institute admits to its sophomore and junior classes a small number of students who have excellent records at other institutions of collegiate rank and who perform satisfactorily on the Caltech Transfer Admissions Entrance Examinations. • Students must have completed their secondary school education, and have subsequently enrolled at a college or university and earned credit, in order to be considered for transfer admission. • Transfer students are not admitted to the senior year at Caltech. • Students who have already completed a bachelor's degree in any subject are not eligible for transfer. Standardized Test Requirements Transfer applicants are not required to submit SAT scores and, during the testing moratorium, Caltech will not review any SAT or ACT test scores in the admissions process. International Student English Proficiency English Proficiency Scores are required of all international students unless 1) your native language is English or 2) English is the primary language of instruction in your secondary school and university. Acceptable English proficiency exams include: • TOEFL Internet Based Test (IBT) • IELTS • Duolingo English Test (DET) Information for Undergraduate Students Evaluation of Written English All entering transfer students will be required to undergo an evaluation of their written English prior to enrolling. Transfer Admissions Entrance Examinations All applicants are required to take Caltech Transfer Admissions Entrance Examinations in mathematics and physics. Further instructions are included with the Caltech Transfer Application. Transfer of Credit The courses for which transfer applicants will receive credit, and the corresponding class standing, will be determined at the time of enrollment. The transfer applicant will submit course descriptions, syllabi, and final transcripts to the Registrar who will present the material to the faculty for evaluation. Faculty members review each course submitted for credit on an individual basis. It is sometimes not possible, therefore, to answer questions regarding the acceptability of course work taken elsewhere. Before the student is admitted, transfer students will work through Admissions to obtain a pre-evaluation estimate. If the standard of work taken elsewhere is uncertain, additional examinations may be required before the question of credit is finally determined. Graduation Requirements Admitted transfer students must meet the following requirements in order to receive a Caltech Bachelor of Science degree. • A Caltech undergraduate degree is based on a four-year residential experience (study abroad included) in which students have the time to explore their academic interests in a deep and rigorous way. Students who are admitted as transfer students or 3/2 students may be granted advanced standing and term credit for academic work accepted in transfer to Caltech. However, transfer and 3/2 students must enroll for a minimum of six terms at Caltech. Any exceptions must be approved by the dean of undergraduate students and the vice president for student affairs. Regardless of the amount of credit awarded upon matriculation, transfer students must spend at least two years (six terms) in residence at Caltech. Students must also earn at least 216 units at Caltech, not including courses taken to satisfy math and science core curriculum requirements. • Students must take, or have taken the equivalent of, all core curriculum courses. . Students must satisfy all of their chosen option's degree requirements. Transfer students may choose from among all Caltech undergraduate options.

ÉCOLE POLYTECHNIQUE SCHOLARS PROGRAM The École Polytechnique Scholars Program offers qualified juniors and seniors the opportunity to spend the fall, winter, or spring term at the École Polytechnique, which is located outside of Paris in the town of Palaiseau, about 40 minutes by train from Paris. Note that the winter and spring terms can only be attended in years that do not overlap with Caltech term dates and only with the permission of École Polytechnique and Caltech. In addition, seniors may not attend the spring term if they plan to graduate in June. The École Polytechnique, often referred to by the nickname "L'X," is the foremost French grande école of engineering (according to French and international rankings). Founded in 1794 and initially located in the Information for Undergraduate Students Latin Quarter in central Paris, it was moved to Palaiseau in 1976. It is one of the oldest and most prestigious engineering schools in the world, with a very selective entrance exam. As one of the world's foremost establishments in science education, the Ecole Polytechnique trains graduates who become outstanding scientists, engineers, researchers, managers, and politicians. At École Polytechnique, students can take courses in one academic area called an approndisement. The subjects are engineering, computer science as well as the sciences, e.g., chemistry, physics, environmental sciences (GPS students) and mathematics. Students can also take one class in the social sciences and humanities if their schedule permits. All students take a French language class. Classes are taught in French or English based on the instructor's preference. However, students must have very good ability in speaking, reading, and writing French before applying for this program. Students will continue to take French at their level while at École Polytechnique. École Polytechnique has different academic schedules depending on the year of study. Caltech students who study at École Polytechnique for the fall term can only select classes from the third year of the École Polytechnique curriculum, and all classes must be selected from this year's curriculum. Note that the second-year classes are not allowed, as this year goes from the fall through January and then has a second semester versus two terms. The third-year specialized curriculum has a schedule that corresponds closely to Caltech's three-term system, and students must take all classes from the third-year curriculum. These classes are equivalent to 100-level classes at Caltech. A minimum 3.3 GPA is required to apply. Eligible sophomores and juniors apply to study during their junior or senior year by the Caltech internal deadline, which is usually in January. Note that students must be nominated by Caltech in order to apply and cannot apply without going through the internal Caltech nomination process, which is run by the Fellowships Advising and Study Abroad Office. Only this office can provide the required nomination. Each year application specifics will be provided to sophomores and juniors in the fall. Students will be required to complete both Caltech Study Abroad Proposal and Forms and complete the École Polytechnique application forms as well as undergoing a formal assessment of French skills by Caltech's French instructor. Please see the Financial Aid section for details on applying for and eligibility for financial aid related to study abroad.

All students live in university dormitories or flats, which are within walking distance from the George Square (humanities and social sciences) and the King's Buildings (the science and engineering campus). The university operates a free shuttle bus from the George Square campus to the King's Buildings campus. Students pay Caltech room, board, tuition, and other standard Caltech fees for the term. There is usually a supplemental charge for housing due to the longer length of the term. The supplement varies Students are admitted into one of Edinburgh's academic departments in the College of Science and Engineering (CSE). Note that students cannot be admitted into the economics department because that is in the College of Humanities and Social Sciences, but they can take 20 credits in that department. Students, whose option is BEM or economics, are allowed to take 40 credits in economics in order to fulfill BEM or economics option requirements if the student also takes 40 credits in the College of Science and Engineering. r sermester and Students take a minimum of 60 Edinburgh credits per semester and a maximum of 80 credits, but no more than five courses. Students will take a minimum of two classes in the department is closest to their option and which will serve as the student's admitting department. The two required classes (18 Caltech units) varies from 20 to 40 Edinburgh credits based on whether the two classes are 10 or 20 credit classes each. Students can take all of their classes in their admitting department or can take classes in other CSE departments provided they meet requirements. Students can take 20 credits (one course) in the College of Arts Humanities and Social Sciences or up to two 40 credits in this college if they take 40 credits in the College of Science and Engineering. Note that 60 credits (4 classes) is the standard course load, but most Caltech students take 70 to 80 credits. Note that at least 36 Caltech units must be taken, i.e., 4 classes/60 credits. A minimum 3.0 GPA is required to apply. Eligible sophomores and juniors should apply by the January deadline for the fall semester at Edinburgh.

LONDON SCHOLARS PROGRAM The Caltech London Scholars Programs offers qualified juniors and seniors the opportunity to spend a fall term at University College London, which is located in the lovely Bloomsbury area of London. University College London (UCL) is on a semester system, and Caltech students attend UCL's autumn semester from about the third week of September to mid-December. All students are required to attend an exchange student orientation the week before the semester begins. Students also attend a new student orientation the first week of the Information for Undergraduate Students semester. All students live in a UCL dormitory, which is located a short walk or short bus ride from the academic buildings of the UCL campus. Students pay Caltech room, board, tuition, and other standard Caltech fees for the term. There is a supplemental charge for housing/board due to the longer length of the term. The supplement varies yearly depending on prices and the exchange rate. Students are admitted into one of UCL's academic departments in the physical, life, or engineering sciences and must take at least 50% of their classes in their Admitting Department. Usually the Admitting Department is in a subject area that most closely corresponds to the student's Caltech option, but there is some leeway in this provided the student has the background to be admitted to the department in question in the STEM subjects. Students cannot be admitted into humanities or social science departments. The remaining 50 percent of classes can either be taken in the Admitting Department, another department in the sciences or engineering, or the humanities and social sciences with the exception of the English literature department, the the Slade School of Design, which do not admit visiting students, even those with majors in English literature or the arts. Note that there are ample opportunities to take literature courses from a number of departments that offer literature classes, e.g., Slavonic and East European studies, Classics, Scandinavian studies, European cultural studies, Hebrew and Jewish studies, French, etc. Note that these departments offer classes taught in translation and in the foreign language. A typical UCL semester class is 15 UCL credits. Caltech students must take 60 UCL credits during their semester at UCL. This would be equivalent to 36 Caltech units unless a class is equivalent to a 12-unit Caltech class. UCL classes fulfill option credit, humanities or social science credit or general credit. Note that the final number of units and whether the units can be used to fulfill departmental requirements will be determined after faculty review upon a student's return to Caltech. Students are only allowed to take Year One classes in the economics department. Students can take higher level economics classes in the School of Eastern European and Slavonic Studies. A minimum 3.3 GPA is required to apply and some departments such as Computer Science (3.9) or the Biological Sciences (3.5) require a higher GPA.

Melbourne is on a semester system, and Caltech students attend Melbourne's second semester from the second week of July to the end of November. Since Melbourne is in the Southern Hemisphere, the university's first semester starts in July and crosses over both the Caltech winter and spring terms. Therefore, students attend Melbourne's second semester, which corresponds better to Caltech's fall semester. All students are required to attend an orientation that takes place at the University of Melbourne the week before the semester begins. Students live in a residence hall, which is located a short walk from the academic buildings of the campus. Halls of residence have either an apartment or suite setup and offer that vary by hall assigned such as a 15-meter outdoor swimming pool and lounge area, barbecue area, workout gym (with plasma TV, cross trainers, free weights, treadmills, exercise bikes, etc.), café, lounge, computer lab, and laundry. Students share a suite or apartment with other students. Students pay Caltech room, board, tuition, and other standard Caltech fees for the term. There is a supplemental charge for housing/board due to the longer length of the Melbourne semester. In some years there could be a supplemental tuition charge. The supplement varies yearly depending on prices and the exchange rate. Students take four classes at Melbourne. Each class is worth 12.5 Melbourne credit points. Of the four classes, students must take two classes related to their option at Caltech and may take up to two outside of their subject, including the humanities and social sciences. Students are eligible to take one class as a research class in an area related to their option. The Melbourne credit load would be equivalent to 36 to 45 Caltech units. Melbourne classes can be used to fulfill option credit, humanities or social science credit, or general credit requirements. Note that the final number of units and whether the units can be used to fulfill departmental requirements will be determined after faculty review upon a student's return to Caltech.

REGISTRATION REGULATIONS PROCEDURES Students must register on the dates specified in the academic calendar. Students are not registered until they have both enrolled in an approved list of courses, and are current with the Bursar's Office. All undergraduate students with an outstanding Bursar's bill balance of $300 or more and graduate students with a Bursar's bill balance of $1,500 or more will have a hold placed on their registration for the subsequent quarter the day before online registration opens. The hold will be Registration Regulations 205 206 released once students have paid their bill in full or worked out a satisfactory payment plan with the Bursar's Office. Any student who has not completed both parts of registration within one week after the first day of classes will be removed from the Institute rolls. A student on leave from, or not registered with, the Institute may not attend classes, live in Institute housing, participate in Institute programs, use Institute facilities, work on campus, or use student services such as Wellness Services, Center for Inclusion & Diversity, Careers, Advising, and Experiential Learning (CAEL), or the Hixon Writing Center during the leave, unless approved in writing by the Dean of Students or designee. The Institute can place a hold on a student's registration in a variety of circumstances including any failure to comply with Institute requirements. Students are required to maintain continuity of registration until the requirements for the Bachelor of Science degree are fulfilled, except in the case of an approved undergraduate student leave. CHANGES IN REGISTRATION All changes in registration must be reported to the Registrar's Office by the student prior to the published deadlines. A grade of F will be given in any course for which a student registers and which they do not either complete satisfactorily or drop. A course is considered dropped when a student drops the course in REGIS or notifies the Registrar's Office in writing. A student may not at any time withdraw from a course that is required for graduation in their option, without permission of the registrar. A student may not add a course after the last day for adding courses, or withdraw from a course after the last date for dropping courses, without the approval of the Undergraduate Academic Standards and Honors (UASH) Committee. In cases where the late addition of a course would have put the student in a position of overload by Add Day of the term concerned, the student must also obtain an approved retroactive overload from the dean or associate dean of undergraduate students. Registration for added courses is complete when a student registers for the course on REGIS or sends a written request to the Registrar's Office with the proper approvals. No credit will be given for a course for which a student has not properly registered. The responsibility for registering or dropping courses (in REGIS or by direct communication with the Registrar's Office) is on the student. Failure to fulfill the responsibility because of oversight or ignorance is not sufficient grounds to petition for permission to drop or add courses after the deadline. Humanities Drop Policy Students who do not attend the first class of the term will be automatically dropped from the class. Students who notify the instructor in advance of their inability to attend the first class may remain enrolled in the class at the instructor's discretion. Information for Undergraduate Students Academic Advisement Students will be assigned first-year advisers, and later option advisers, who will guide students to resources about the curriculum, graduation requirements, and Institute policies and procedures. Through the academic advising experiences at Caltech, students will develop an educational plan for successfully achieving their goals and select courses each quarter to progress toward fulfilling that educational plan. Undergraduate students are required to meet with their adviser at least once a year. Failure to meet at least once prior to the start of spring term will result in a hold placed on the student's record which will prevent them from registering online. Summer Research or Summer Reading Qualified undergraduate students who are regular students at the Institute are permitted to engage in research or reading during the summer, but in order to receive academic credit the student must have the approval of their division and must complete the registration process for such summer work before June 1. Any requests to add research after June 1 must be submitted as a Late Add petition to the Undergraduate Academic Standards and Honors Committee (UASH) as well as be approved by the Division Chair. An undergraduate may not receive payment for research carried out for academic credit. Students who are registered for summer research or reading will not be required to pay tuition for the units. A student may apply up to 18 units of summer research per summer and 36 units in total toward Institute graduation requirements. UNDERGRADUATE STUDENT LEAVES OF ABSENCE Voluntary Leaves Personal Leaves A student may request a voluntary leave of absence for personal reasons (personal leave) by submitting a written petition via completion of the undergraduate leave form. International students should consult with the International Student Programs Office regarding visa implications prior to submitting the leave petition. The dean or designee may grant a personal leave provided (a) the student is in good standing, in other words does not have to meet special academic or disciplinary requirements as a result of reinstatement, (b) the leave is for one year or less, although special circumstances can be considered for a longer leave, and (c) the leave extends over a period that includes at least one full term. A student on personal leave may not attend classes, live in Institute housing, participate in Institute programs, use Institute facilities, work on campus, or use student services, such as the Health and Counseling Services or Center for Inclusion & Diversity, during the leave, unless approved in writing by the dean or designee. Both Career Advising and Experiential Learning (CAEL) and the Hixon Writing Center (HWC) are, by default, open to all students who have not been permanently separated from the Institute, regardless of leave or Registration Regulations 207 208 registration status, unless otherwise revoked by the director of the relevant center. A disciplinary proceeding brought against a student may continue during the period that a student is on a personal leave. The Institute reserves the right to impose discipline against a student on personal leave should circumstances warrant. A petition to return from a personal leave should be submitted six (6) weeks before the first day of the term for which the student intends to return. Medical Leaves If a student is unable to complete their coursework due to medical reasons, the student may petition for a medical leave of absence by submitting a written petition via completion of the undergraduate leave form. The dean or designee may grant a leave for medical reasons, provided the petition is recommended by the director of Health and Counseling Services or designee. International students should consult with the International Student Programs Office regarding visa implications prior to submitting the medical leave petition. Medical leaves are expected to extend over a period that includes at least one full term, although special circumstances may be considered for approval of a shorter leave upon the recommendation of a student's treatment team. Students may be required to sign a release of information form authorizing their treatment provider to communicate relevant medical information to representatives within Health and Counseling Services and the Dean's Office to facilitate evaluation of the need for the leave and to determine appropriate conditions associated with the leave and establishing expectations for return from the leave. The Institute may impose conditions on return from a medical leave, which may include confirmation from the student's health care provider that the student is following the recommended course of treatment, the student's consent for the provider to discuss the student's condition or progress during the leave with Caltech officials, including representatives of Health and Counseling Services and the Dean's Office, and an independent evaluation of the student's readiness to return by a qualified medical professional. Certain conditions of return will be specified at the time of the leave approval. A petition to return from medical leave must be submitted six (6) weeks before the first day of the term for which the student intends to return. The return process includes an interview with the director of Health and Counseling Services and the submission of a completed return from medical leave and provider recommendation forms. Students are expected to sign a release of information form authorizing their treatment providers to communicate with Caltech, including representatives of Health and Counseling Services and the Dean's Office to determine readiness to return and recommendations for reasonable accommodations. Final approval of the petition is the responsibility of the dean or designee. If the student is permitted to return from the leave, any conditions of return will be communicated to the student in writing. Information for Undergraduate Students A student returning from a leave for medical reasons will maintain the same academic standing that they had previously and will be subject to the same academic requirements for maintaining academic progress unless an exception is granted -i.e., if on academic probation, the student will remain on probation upon return from leave. Additional information and resources regarding medical leave, including financial and transcript implications, can be found at deans.caltech.edu. While on Medical Leave It is the expectation that a student on medical leave will focus on receiving treatment to manage the condition(s) that precipitated the leave. A student on medical leave may not attend classes, live in Institute housing, participate in Institute programs, use Institute facilities, work on campus, or use student services such as Health and Counseling Services, Center for Inclusion & Diversity, or the Hixon Writing Center during the leave, unless approved in writing by the dean or designee. Career Advising and Experiential Learning (CAEL) is, by default, open to all students who have not been permanently separated from the Institute, regardless of leave or registration status, unless otherwise revoked by the director of CAEL. Pregnancy Leave Consistent with Caltech policy and the requirements of Title IX, students who are unable to complete their coursework or other course of study for a period of time due to a pregnancy, childbirth, and related medical conditions are eligible for a medical leave of absence. Students who are pregnant or who have recently given birth are also eligible for reasonable accommodations. A pregnant student who wishes to take a medical leave should submit a completed petition to the Dean of Undergraduate Students Office after obtaining a recommendation from the director of Health and Counseling Services. Medical documentation from the student's treating medical provider is required The Institute also provides reasonable accommodations to pregnant students consistent with federal and state law. Reasonable accommodations may include allowing pregnant students to maintain a safe distance from hazardous substances, allowing them to make up tests and assignments that are missed for pregnancy-related reasons or excusing of absences that are medically necessary. Bonding An enrolled student in good academic standing who chooses to take a leave of absence because of the birth of their child may request a bonding leave by submitting a completed petition form to the Dean of Undergraduate Students Office for approval. Registration Regulations 209 210 Involuntary Leave The dean or designee may determine that it is necessary to place a student on an involuntary leave in a variety of circumstances, including when a student demonstrates behavior that poses a threat to health or safety, causes significant disruption to the Caltech community, for the personal safety or welfare of the student involved, as an interim measure, or as a result of a disciplinary action. The dean may impose an involuntary leave in appropriate circumstances, such as where a student's behavior: (1) has, or threatens to, cause significant property damage; (2) significantly disrupts the Caltech community; (3) presents a substantial risk of harm to self or others; (4) indicates the student is unable or unwilling to carry out self-care obligations; or (5) violates a Caltech policy or the honor system. An involuntary leave also may be imposed when that the student requires a level of care from the Institute community that exceeds the reasonable accommodations, resources and staffing that the Institute can reasonably be expected to provide for the student's well-being. Emergency Leave If the dean determines that a student's continued presence is likely to pose a substantial risk to the safety and well-being of the student or others, the dean may place the student on an emergency interim leave before a final determination is made. The dean will consider relevant information, including relevant information provided by the student, if available within the timeframe needed to make a decision, before deciding on an emergency interim leave. An emergency interim leave will remain in effect until a final decision has been made. Review and Decision Process If the conduct has been the subject of an investigation or review under an Institute process or procedure, the dean will consider the findings and conclusions reached in that process. In other circumstances described above, in making an informed decision to place a student on involuntary leave, the dean will conduct an individualized assessment and consider relevant information including information provide in a timely manner by the student. The dean may consult with other Institute personnel, including but not limited to, security and residential life personnel, staff, faculty, and other individuals or departments. If appropriate and feasible, the dean may seek cooperation and involvement of parents or guardians of the student. Medical information, including medical information provided in a timely manner by the student, may be considered if the behavior is associated with a physical or mental condition. In appropriate cases, the dean may consult with the director of Health and Counseling Services, or designee, and/or require a physical or mental evaluation from a health professional if the dean believes such an evaluation is necessary in order to make an informed decision. Students are expected, if necessary, to sign a release of information to facilitate discussions between Caltech and the health professional conducting Information for Undergraduate Students the evaluation. The dean will also consider whether relevant risk factors can be eliminated or reduced to an acceptable level through reasonable accommodation. Appeal A decision by the dean to place a student on involuntary leave may be appealed in writing within 10 days to the vice president for student affairs (or designee). If the leave is imposed as a sanction resulting from a finding of responsibility under an Institute process any applicable limitations on grounds for appeal will apply. Written Decision The student will be advised in writing of the decision to impose an involuntary leave. The dean may stipulate conditions that must be met before the student may return. An involuntary leave may be a permanent separation from the Institute (i.e. expulsion); for a specific duration or until certain conditions have been met. If the involuntary leave is not a permanent separation, the student will be advised of the length of the leave and/or any conditions for return. While on Leave A student on involuntary leave may not attend classes, live in Institute housing, participate in Institute programs, use Institute facilities, work on campus, or use student services such as Health and Counseling Services, Center for Inclusion & Diversity, or the Hixon Writing Center during the leave, unless approved in writing by the dean or designee. A student on interim involuntary leave may be permitted to remain in Caltech housing and have continued access to student services such as Health and Counseling Services until a final decision is made, if appropriate under the circumstances and as approved by the dean. Return from Leave A student on involuntary leave will not be allowed to return until the dean makes a fact-specific assessment of the circumstances, considers relevant risk factors, and concludes that the student does not pose a significant disruption to the functioning of the Institute community and/or does not pose a substantial risk to the health and safety of the student or others. The dean will consider relevant information, including information provided by the student. In cases where a student has a physical or mental condition associated with the behavior triggering the leave, the dean will also consider whether the relevant risks can be eliminated by a reasonable accommodation. The dean may consult with other Institute administrators, as appropriate, in making their decision. The student will be notified in writing of the dean's determination of whether the student will be permitted to return from a leave, will not be permitted to return from the leave, or will be permanently separated from the Institute. If the student is permitted to return from the leave, any conditions of return will be communicated to the student in writing. Registration Regulations 211 212 While on Leave (all leaves) Caltech considers students on an approved leave to be matriculated; however, students on leave are not currently enrolled and therefore do not enjoy all rights and privileges of enrolled students. Unenrolled students, and accordingly, students on leave, have limited access to Caltech's educational activities, programs, and services. They may not attend classes or labs, live in Institute housing, or access certain student resources, including Student Wellness Services and Residential Life activities, programs, and services during their leave. Career Advising and Experiential Learning (CAEL) is, by default, open to all students who have not been permanently separated from the Institute, regardless of leave or enrollment status, unless otherwise revoked by the Director of CAEL or the relevant deans' office. For questions regarding the full scope of these limitations, please contact the relevant deans' office. Students may consult with their advisor and otherwise plan for their academic future; however, they will not receive credit for courses unless they are properly enrolled. Students who are on leave are still subject to all Institute policies, including the Institute Sex- and Gender-Based Misconduct Policy. Violations of policy may affect a student's eligibility to re-enroll. Withdrawal from the Institute Formal separation from the Institute is effected by filing a completed undergraduate leave form in the dean of students office to be forwarded to the registrar and other appropriate offices. The effective date of a withdrawal is entered by the dean or designee. A student withdrawing from the Institute at any time during the term without filing a formal undergraduate leave form will not be considered withdrawn. In such a case, any grades reported by the instructors will be recorded on the official transcript, and the grade of F will be recorded for all other courses. A student who withdraws, or is absent for a term (or longer), without an approved undergraduate student leave must petition for reinstatement to return to the Institute. Return from involuntary leave requires approval through the dean of students office. Reinstatement rules are listed under scholastic requirements. If the withdrawal occurs after Add Day of any term, a W (standing for "withdrawn") will be recorded on the student's transcript for all courses in which the student is enrolled. A grade of W is not included in the computation of the student's grade-point average. The record will also indicate whether an undergraduate student leave was granted. SCHOLASTIC REQUIREMENTS All undergraduates are required to meet certain scholastic standards as outlined subsequently. Information for Undergraduate Students ELIGIBILITY TO BE ENROLLED All undergraduate students must complete a minimum of 27 units per term with a grade-point average of at least 1.9 in order to be eligible to remain enrolled in classes. First-year students are not held to the 1.9 GPA requirement during the first two terms when all courses are taken pass/fail. A student may be excused from the 27-unit eligibility requirement if an underload petition has been approved, prior to Add Day, by the dean or associate dean of undergraduate students. Under exceptional circumstances the deans may waive the requirement that such a petition be approved prior to Add Day, but may do so only once during that student's career at Caltech. In addition, students must earn a total of 108 units per year; this averages to 36 units per term. The 108 unit requirement may be waived in the case of an approved underload by Add Day, terms away, or having been academically ineligible in one of the past three terms. When a student is ineligible for the first time, students are to send a reinstatement petition to the dean or associate dean of undergraduate students. The dean may choose to reinstate them, in which case they will be on academic probation. Alternatively, the dean may direct them to petition the Undergraduate Academic Standards and Honors Committee (UASH) for reinstatement. UASH will either approve their petition for reinstatement and place them on academic probation, or require them to withdraw from the Institute for at least two terms. When a student becomes ineligible a second time, they will be required to withdraw from the Institute for at least two terms. Summer does not count as a term. A student who has been required to leave the Institute because of academic ineligibility may, after at least two terms of leave, petition the Undergraduate Academic Standards and Honors (UASH) Committee for reinstatement. The UASH Committee's decision regarding reinstatement will be based largely on whether or not such students have made good use of their time while away from the Institute. Useful activities include being gainfully employed, having an internship, engaging in a significant amount of volunteer work, or successfully completing courses at another college or university. The Committee will also expect that students applying for reinstatement will have completed work in all Caltech classes in which they had received an E or I grade. Students who are ineligible to petition may request an exception to the above. To do so, they must first obtain permission from two of the following three individuals: the dean of undergraduate students, the chair of the UASH Committee, and the Registrar. Such requests require that a reinstatement petition be sent to the Registrar's Office at least three days prior to the next UASH Committee meeting's published deadline. When a student becomes ineligible a third time, they will not be allowed to continue to enroll at Caltech. If a student is academically ineligible, and not reinstated, they may not continue to live in student housing. See Summer Housing in Section 1 of the catalog for additional information. Scholastic Requirements 213 214 Departmental and Option Regulations By the middle of the third term, first-year students must notify the Registrar's Office of their selection of an option in engineering, humanities, social sciences, or science to be pursued in subsequent years. Upon the selection of an option, a first-year student will be assigned an adviser in that option, whose approval must then be obtained for registration for the following year. Undergraduate students may request to add an approved minor to their program of study. The request for a minor must be approved by the option representatives of the student's option and proposed minor. A plan must be presented which meets the minimum requirements for both the option and the minor, but the option representatives may impose additional requirements as well. The approved request must be submitted to the registrar before the start of the senior year. Undergraduate students may be allowed to major in two options for the Bachelor of Science degree. In order to do so the student must present a rationale for the double option and a plan of study leading to completion of the degree in four years. The plan, and any substantive modifications, must be approved by a committee composed of the option representatives of the two options. The plan must meet the minimum requirements for both options as set forth in this catalog, but the committee may impose additional requirements as well. The approved plan should be submitted to the registrar during the sophomore year, but in any case no later than the start of the senior year. The student will then be assigned an adviser by each option. Consult the registrar for appropriate procedures. Continuing in an Option Students whose grade-point averages are less than 1.9 at the end of an academic year in a specific group of subjects designated by their department or option may, at the discretion of their department, be refused permission to continue the work of that option. Such disbarment does not prevent the students from continuing in some other option or from taking additional courses to raise their average in their original option. Students without an option will fall under the direct jurisdiction of the dean of students. Students may remain without an option for no more than one year. Change of Option An undergraduate in good standing at the Institute shall be permitted to transfer into any option of their choice provided they have (a) a 1.9 GPA in subjects required for graduation in that option or in a specific group of subjects designated by that option or (b) permission of the option representative or committee. A change of option is effected by obtaining a Change of Option petition from the Registrar's Office. The completed petition must then be signed by the option representative for the new option (who will assign a new adviser), and filed with the Registrar's Office. Institute regulations require that a student who has made normal progress at the Institute be able to change options at any time up to the end of the sophomore year without penalty either as Information for Undergraduate Students to time until graduation or as to excessive unit requirements in any term. Term Examinations Term examinations will be held in all subjects unless the instructor in charge of any subject shall arrange otherwise. No student will be exempt from these examinations. When conflicts exist in a student's schedule, it is the student's responsibility to report the conflict to the instructor in charge of one of the conflicting examinations and make arrangements for another time. Satisfactory Academic Progress Eligibility to register is determined by the student's record as of the first day of classes of the term in which registration is sought. A student will be declared ineligible to register if they have completed fewer than 27 units with a 1.9 grade point average in the previous term. Graduation Requirement To qualify for graduation a student must complete the prescribed work in one of the options with a passing grade in each required subject and with a grade-point average of 1.9. A grade of F in an elective course need not be made up, provided the student has received passing grades in enough other accepted units to satisfy the minimum total requirements of the option. A Caltech undergraduate degree is based on a four-year residential experience (study abroad included) in which students have the time to explore their academic interested in a deep and rigorous way. Students who are admitted as transfer students or 3/2 students may be granted advanced standing and term credit for academic work accepted in transfer to Caltech. However, transfers and 3/2 students must enroll for a minimum of six terms at Caltech. All other regularly admitted students must enroll for four years (12 terms). Any exceptions to the four year residence requirement must be approved by the dean of undergraduate students and the vice president for student affairs. Candidacy for the Bachelor's Degree Students must declare their candidacy for the degree of Bachelor of Science to the registrar on or before the first Monday of November preceding the date on which they expect to receive the degree. All subjects required for graduation, with the exception of those for which the candidate is registered during the last term of their study, must be completed and the grade recorded by the second Monday of May preceding commencement. Graduation in the Normally Prescribed Time Any undergraduate student who fails to complete the requirements for graduation at the end of 12 terms must petition the Undergraduate Academic Standards and Honors (UASH) Committee for approval to register for further work each term. Scholastic Requirements 215 216 Excess of or Fewer Than Normal Units (Overloads and Underloads) An overload is defined as registration for more than 48 units for an undergraduate. This limit corresponds to five 9-unit classes plus a 3-unit non-academic class (PE, PVA, SA) or four 9-unit classes plus one 12-unit class. Classroom and laboratory courses are to be limited to 45 units for first-year students for the first two terms and the remaining three units should be used for frontier ("pizza") courses, PE, PVA, SA, or research. Students may take up to 51 units (inclusive) but it requires their adviser's approval for such an overload. To take more units than 51, students will need to petition the undergraduate dean, with the expectation that permission will be granted only in exceptional cases. This policy is aimed at having no effect on currently recommended courses of studies in all options, while putting a very high bar for taking 6 full-time classes simultaneously. A student who wishes to carry an overload in any term must obtain the approval of their adviser and the dean or associate dean of undergraduate students. Petitions for overloads must be submitted one week before the last day for adding classes in any term. An underload is registration for fewer than 36 units. Underload petitions for first-year students, sophomores, and juniors must be approved by the adviser and the dean or associate dean of undergraduate students. Seniors may take an underload by presenting for the Registrar's approval a senior underload petition and a course plan for graduation the following June that does not require an overload in any term. Completing fewer than 27 units without prior approval will result in ineligibility; for more information on eligibility, see Scholastic Requirements. Underloads during the first 12 terms will not result in a tuition reduction, only in a reduction in financial aid. After completing 12 terms, tuition will be charged per unit. The dean or disability services coordinator will evaluate exceptions due to medical reasons. For more information about underloads and tuition, see Underloads. For more information about impact to aid, see Underloads and Financial Aid: The Impact of Less than Full-time Enrollment. ALLOWANCE AND TRANSFER OF CREDIT Transfer of Credit from Other Institutions Regularly enrolled students who want to obtain credit for college courses taken elsewhere should obtain the permission of the dean of students and have a copy of the transcript of their work sent to the Registrar's Office. The student should then obtain an Allowance of Credit form from the Registrar's Office and take this, with the transcript as well as any supporting class materials required by the option representative, to the representative of the option in which credit is desired. Pending approval by the option representative, credit will be granted when the Allowance of Credit form, with the appropriate signatures, is returned to the office. Information for Undergraduate Students Allowance of Credit in the Humanities and Social Sciences In general, Caltech students should fulfill Caltech course requirements by taking courses at Caltech. Students are expected to have a well-reasoned educational goal for taking classes elsewhere. The only exceptions are transfer students admitted to advanced standing. Credit for comparable work done at other institutions with similar academic standards is not granted automatically. Students who wish to take courses elsewhere (whether on leave, in the summer, or during the academic year) should consult, in advance, with the executive officer for the humanities or the executive officer for the social sciences, or their designees, to minimize any misunderstanding regarding the nature of credit they may receive. Upon completion of the course, the student must obtain an Allowance of Credit form from the registrar, obtain the signed approval of the executive officer, or their designee, for transfer credit, and return the completed form to the Registrar's Office. The executive officers are the final authority in the allowance of credit in HSS courses. Guidelines and specific information about allowance of credit are available from the Division of the Humanities and Social Sciences. Other Allowances of Credit Except for transfer credit and credit based on Caltech placement exams upon admission, credit will not be granted for Caltech courses in which the student is not officially enrolled, except in special circumstances by arrangement with the instructor. Such arrangements must be approved by the Curriculum Committee, and the student must petition the Committee before the work is undertaken. UNDERGRADUATE EXPENSES For first-year and transfer students applying for admission, there is a $75 application fee. This fee is nonrefundable. Housing contracts must be submitted to the Housing Office by the date specified in the instructions accompanying the contract. EXPENSE SUMMARY 2022-2023 General: General deposit... Orientation fee.. Tuition $100.00' $500.00' $58,479.00 'This charge is made only once during residence at the Institute. Other: Student fees. $2,385.00 Room (contract price). $10,815.00 Board (5 days / week). $7,791.00 Books and supplies (est.). $1,428.00 Personal expenses (est.). $2,700.00 The tuition and fees charge for all students is payable in full before the first day of classes unless the student enrolls in the Transact Undergraduate Expenses 217 218 Payment Plan. The fee to enroll in the plan is $35.00 per term. Enrollment in the Transact Payment Plan will be available September 12, 2022 when the Fall Term statement is published. Tuition for the baccalaureate degree is based on four years (12 terms) of residence regardless of unit load each term or if a student completes graduation requirements a term(s) early. The 12 term residence requirement is separate from and in addition to any other degree requirements. Official study abroad programs listed in the Catalog fulfill one term of the 12 term requirement. Since a Caltech degree is based on a four-year residential requirement, entering students should expect to be in residence and to be billed tuition for a full four years. Any exceptions must be approved by the dean of undergraduate students and the vice president for student affairs. In addition, aid may not be disbursed to a student to cover full tuition if they are no longer attending classes. REFUNDS AND FEES Refunds and Repayments For all students, the institutional charges, e.g., tuition and room and board, will be prorated according to the amount of time the student spent in academic attendance before withdrawing from the Institute before the end of the sixth week of the term. These prorated charges will be compared to the payments received on behalf of the student, and the Institute will determine whether the student is entitled to a refund or owes additional funds to Caltech. For students receiving funds from federal Title IV, from Caltech, and/or from state programs, the Institute will follow federal and other applicable regulations to determine the amount of all program funds the student has earned at the time of withdrawal. In general, the amount of financial aid earned is based on the amount of time the student has spent in academic attendance. If the amount of aid disbursed to the student is greater than the amount the student has earned, unearned funds must be returned. If the amount the student was disbursed is less than the amount the student earned, the student will be eligible to receive a post-withdrawal disbursement. Determining the Student's Last Date of Attendance or Withdrawal The Office of the Registrar is responsible for obtaining requests for withdrawal from the undergraduate or graduate dean and for processing official withdrawals. In order to calculate the refund or repayment, Caltech will establish the student's withdrawal date. This date is one of the following: • the date that the student began the withdrawal process prescribed by Caltech; • the date the student otherwise provided official notification to the registrar (written or oral) of their intent to withdraw; • the midpoint of the academic term if no official notification is provided; Information for Undergraduate Students • the date determined by the registrar if there are special • circumstances (illness, accident, grievous personal loss); or the date the registrar determines the student has not returned from an approved student sabbatical or if the student does not qualify for a sabbatical. Academically Related Activities that Determine Academic Attendance The Institute may use the last date of attendance at an academically related activity as the student's withdrawal date. This may occur if a student begins the withdrawal process and then attends an academically related activity after that date. Caltech considers an academically related activity to include the following: • attendance at a lab • attendance at a lecture • completing a quiz and/or test • participation in a study session • academic counseling session • academic advisement session • turning in a class assignment Determining the Return of Federal Funds The Financial Aid Office and/or the Graduate Office will calculate the federal funds that must be returned to the appropriate federal accounts. If a student withdraws from the Institute prior to the first day of classes for the period of enrollment, Caltech will return 100 percent of the student's federal financial aid in accordance with federal procedures, as well as Caltech and/or state grants or aid. If a student withdraws any time after the first day of classes for the period of enrollment, the Institute will perform the following: • Determine the percentage of the payment period that the student completed. If the student completed more than 60 percent of the period, they earned 100 percent of the aid for the period. If the student completed 60 percent or less, the percentage of the period completed is the percentage of aid earned. This percentage is determined by dividing the number of days attended in the period of enrollment by the total days in the period. • Apply the earned percentage to the amount of aid actually disbursed and the amount that could have been disbursed ("earned aid"). Subtract earned aid from aid that was actually disbursed. This results in the amount of unearned aid to be returned. • The Financial Aid Office and/or the Graduate Office (as appropriate) will allocate the return of funds back to the student 1.

Federal Work Study is not included in any of these calculations. Appeals on Refunds Any questions or problems related to refunds should be directed to the Bursar's Office. For further information on refunds and repayments, contact the Financial Aid Office, the Graduate Office, or the Bursar's Office. Underloads Students who register for less than 36 units ("Underload") will not receive a reduction of tuition. Full tuition will be charged to underloading students' accounts. Also, applicable financial aid will be reduced, in underload situations. For specific information on underload requirements, and special circumstances where an underload may be granted, see Excess of or Fewer Than Normal Units (Overloads and Underloads). Information regarding financial aid and underloads can be found in Part-Time Enrollments (Underloads.) For those undergraduate students who are eligible for underloading after completing 12 terms or by approved medical exception (Excess of or Fewer Than Normal Units (Overloads and Underloads)), the tuition will be adjusted after Add Day at the AY2022-2023 rate of $541.00 per unit plus $795.00 for student fees per term. The minimum tuition amount is ten units, a charge of $5,410.00 per term. Dropping a Course Students who are not enrolled full-time as of the last day to add courses will have their aid revised. Generally, students enrolling less than three-fourths time will have an increased work award. Additional information is available in the Financial Aid Office. For more information about impact to aid, see Underloads and Financial Aid. Refund upon Withdrawal When a student, for whatever reason, withdraws from Caltech during an academic term, a refund of tuition as well as room and board, if applicable, is calculated. The amount of refund is determined by how much of the term has elapsed. If the student is a recipient of student financial assistance, that assistance, if applicable, will be reduced as a result of their withdrawal. Recent federal legislation determines the amount of refund for recipients of federal Title IV student assistance. It is the purpose of this section to inform students of the financial implications of withdrawal. If the student is not a recipient of federal financial aid, the Institute's refund policy returns any refund of tuition or room and board first to Information for Undergraduate Students the programs from which assistance has been received (i.e., scholarships, Caltech gift assistance). Any amount remaining will then be returned to the student. The non-Title IV portion will be distributed as appropriate, first to outside agencies, as required, then to the Caltech grant, scholarship, or loan, depending on the composition of the aid package. These distributions will occur as credits to the appropriate aid funds and charge(s) to the student's Caltech account. If the student is the recipient of federal Title IV student assistance, any refund must then be applied first to the federal aid programs) in the prescribed order listed under Determining the Return of Federal Funds. In the event that a student's disbursed financial aid exceeds the direct costs on the student's personal account, a credit balance will result. Withdrawal will result in the reversal or repayment of the resulting credit balance. General Deposit Each new student is required at their first registration to make a general deposit of $100, to cover possible loss and/or damage of Institute property. Upon graduation or withdrawal from the Institute, any remaining balance of the deposit will be applied to the student's outstanding balance or refunded if there is no unpaid balance. Fees for Late Registration Registration is not complete until the student has enrolled in a program approved by their adviser and has paid tuition and other fees. A penalty fee of $50 is assessed for failure to register within five days of the scheduled dates. Fees for Late Payment A $50 late penalty may be charged by the Bursar's Office for failure to clear a past-due account at the beginning of instruction. Honor System Matters Monies owed to the Institute resulting from a disciplinary decision may be collected through the Bursar's Office, at the request of the dean of students. Special Fees Students taking the Summer Field Geology course (Ge 120 ab) should consult with the division about travel and subsistence arrangements and costs. Unpaid Bills All bills owed the Institute must be paid when due. Any student whose bills are past due may be refused registration for the following term. All undergraduate students with an outstanding bursar's bill balance of $300 or more will have a hold placed on their registration for the subsequent term the day before online registration opens. The hold will be released once students have paid their bill at the Bursar's Office. Diplomas will not be released until the bursar account is paid in Undergraduate Expenses 221 222 Caltech ID Card Charges If an undergraduate student owes more than $300, the student's ID card will be deactivated and they will be unable to charge any new purchases. Cards will be reactivated once students have paid their bill in full at the Bursar's Office. FINANCIAL AID Caltech believes that qualified students who wish to attend the Institute should not be prevented from doing so for financial reasons. Although the Institute expects students and families to finance the cost of education to the fullest extent possible, the Institute will make every effort to assist those who need help. Demonstrated financial need is the difference between the annual cost of attending Caltech and the amount the student and parents can reasonably be expected to contribute toward those costs. Costs include actual tuition, student fees, room and board, books and supplies, and personal expenses. For U.S. citizens or eligible noncitizens who reside in the United States, Canada, Mexico, or Guam, costs include a travel allowance designed to (partially) offset the cost (airfare) of two round-trips from a student's home during the academic year. Caltech's estimate of a family's ability to contribute is determined annually in accordance with nationally established guidelines. Eligibility for each type of assistance varies, depending upon the source of funds. Assistance offered by Caltech includes federal, state, and institutional grants, subsidized part-time jobs, and low-interest loans. U.S. citizens or eligible noncitizens (as defined in the Free Application for Federal Student Aid [FAFSA]) may apply for state and federally funded programs. International students may apply for institutionally funded programs. Applications for admission are evaluated separately from requests for financial aid. Students with complete financial aid applications on file will be considered for all applicable types of need-based assistance. A renewal application must be submitted each year. In addition to direct financial assistance, information is available, upon request, about education payment plans and financial-planning resources. (Learn about non-need-based scholarships and prizes under Prizes and Awards.) All students who believe they will need assistance to attend Caltech are encouraged to submit a financial aid application. The final day to complete a financial aid application or request a loan is one day after the beginning of the registration period for the term following your last term of enrollment for the year. Please use the table below to determine which deadline applies to you. Information for Undergraduate Students Last Term of Enrollment in Academic Year 2022-23 Hard Deadline Fall Term November 18, 2022 Winter Term February 24, 2023 Spring Term May 26, 2023 The Financial Aid Office staff is happy to talk with students and their families at any time to explain the application process, Caltech's computations, and available programs. For further information on the determination of financial need and on application procedures, as wel as on financial aid awards and programs, contact the Financial Aid Office, California Institute of Technology, Mail Code 20-90, Pasadena, CA 91125; call (626) 395-6280; or visit the Caltech Financial Aid Office website at finaid.caltech.edu. HOW TO APPLY FOR FINANCIAL AID Application Process for Caltech and Federal Financial Aid for Entering Students (U.S. Citizens and Eligible Noncitizens) Slightly different procedures and deadlines exist for each category of students applying for financial aid. Detailed descriptions of these procedures and priority due dates for prospective and continuing students may be found on the Caltech Financial Aid Office website at finaid.caltech.edu. International Applicants If you are applying for admission as a first-year student for the fall of 2023 and are not a citizen or permanent resident of the United States at the time of your application for admission, you will need to refer to the Caltech Financial Aid Office website at finaid.caltech.edu for instructions for applying for financial aid. International applicants who do not apply for financial aid by published deadlines, or who are denied aid for their first year at Caltech, are not eligible for need-based financial aid for any other academic period while they are undergraduates at the Institute (with the exception of citizens of Canada and Mexico). Those with financial aid offers will be eligible to apply for assistance in subsequent years. All eligible students must reapply for aid each year. International students are required to complete the CSS/Financial Aid PROFILE. This online application collects family income and asset information from international students. Students will need to complete and submit the CSS PROFILE online at cssprofile.collegeboard.org after they have been admitted into Caltech. (Students can also visit EducationUSA Advising Centers at educationusa.state.gov/find-advising-center if you need assistance completing your CSS PROFILE.) Please refer to the complete application instructions provided on the Caltech Financial Aid Office website at finaid.caltech.edu. Financial Aid 223 224 TYPES OF AID AVAILABLE There are three basic categories of financial aid that may be awarded. 1. Grants and scholarships represent "gift aid," which does not need to be repaid. In general, a Caltech scholarship is awarded based on financial need. Caltech named and/or endowed scholarships are considered to be based on need and merit. If you qualify for a state or federal grant, this grant will be included in your financial aid package. 2. Federal Work-Study or Caltech Work-Study represents student employment funds that have been allocated for you to earn during the academic year. Summer Caltech Work-Study represents funds that have been allocated for you to earn during the summer. While a work-study award is not a guarantee of employment, Caltech generally has more opportunities for student employment than it has students interested in working. 3. Low-interest educational loans: Students are generally offered Caltech/Institute loans. Students may be awarded Federal Direct Stafford Loans if they request them. CALTECH SCHOLARSHIPS Awarded to students with demonstrated financial need. Recipients are expected to be enrolled full-time. The named and/or endowed scholarships are also need-based, but many have a merit component. Recipients of named and/or endowed scholarships are often selected after their initial financial aid offer based on scholarship-specific eligibility. These scholarships are almost always used to replace some or all of the recipient's Caltech scholarship. The Financial Aid Office makes every attempt to renew these scholarships, contingent upon the recipients continuing to meet the specific eligibility criteria. FEDERAL GRANTS Federal Pell Grant Awarded to exceptionally needy undergraduate students who are seeking their first bachelor's degree. Amounts are set by the federal government based on need and enrollment status. In 2022-23, awards ranged from $692 to $6,895 for full-time students; awards for part-time students are set in proportion to their enrollment, i.e., three-quarter time, half-time, less than half-time. Recipients must be in good academic standing. Federal Supplemental Educational Opportunity Grant Awarded to undergraduates with demonstrated need who are seeking their first bachelor's degree. Priority goes to full-time Pell Grant recipients. Recipients must be in good academic standing. Awards cannot exceed $4,000 per year. Information for Undergraduate Students STATE GRANTS Cal Grant A Provides tuition and fee assistance to undergraduate California residents seeking their first bachelor's degree. Awarded on the basis of cumulative grade-point average and financial need. Qualifying students can receive up to $9,358, renewable for up to four years. Continuing Cal Grant recipients must maintain good academic standing in addition to financial need. They are not required to resubmit verification of their grade-point average for renewal. Cal Grant B Provides a living-allowance stipend and tuition/fee assistance to undergraduate California residents seeking their first bachelor's degree. Awards are based on cumulative grade-point average and high financial need. Recipients are generally from disadvantaged economic or educational backgrounds. Awards for first-year students provide up to $1,648 for books and living expenses. When renewed or applied beyond the first year, awards also include tuition and fee assistance of up to $9,358. Continuing Cal Grant recipients must maintain good academic standing in addition to financial need. They are not required to resubmit verification of their grade-point averages for renewal. Other State Grants Other states, such as Pennsylvania, Vermont, and Rhode Island, may offer grant assistance to their residents who plan to attend Caltech. Students are encouraged to contact their respective state post-secondary agencies for specific eligibility and renewal criteria EDUCATIONAL LOANS An educational loan is a serious financial obligation and must be repaid. You should carefully consider the repayment obligation before you accept educational loans. Loans can be an invaluable resource for many students and their families in financing a college education. Students can postpone paying a portion of their educational costs until they complete their education or leave school. The repayment period on most loans can extend up to 10 years after graduation or leaving school. Graduating with educational debt is a fairly common experience for students. At Caltech, however, the average educational indebtedness at graduation is significantly lower than the national average for students attending four-year private and public colleges. The William D. Ford Federal Direct Loan Program This program offers eligible students and parents the opportunity to borrow money directly from the federal government to help pay the cost of attendance at Caltech. The U.S. Department of Education makes loans, through Caltech, directly to students and/or parents. The Institute will use the loan(s) to pay your tuition/fees and other direct charges such as room and board, and give the student any remaining Financial Aid 225 226 money for indirect costs. Students and/or parents make their repayments directly to the federal government. Direct loans include 1. The Federal Direct Stafford Loan Program; 2. The Federal Direct Parent PLUS Loan Program; 3. The Federal Direct Graduate PLUS Loan Program; and 4. The Federal Direct Consolidation Loan Program. Federal Direct Stafford Loan There are two types of Federal Direct Stafford Loans: subsidized and unsubsidized. The federal government pays the interest on subsidized loans while the borrower is enrolled at least half-time and during authorized periods of deferment. The interest on unsubsidized loans begins to accrue immediately upon disbursement and is generally capitalized (added to the amount borrowed) when the borrower is no longer enrolled at least half-time. Eligibility for subsidized Stafford Loans is based on financial need as demonstrated by the FAFSA. Students who do not demonstrate sufficient need or whose need is met may borrow unsubsidized Stafford Loans provided their total financial aid, including the Stafford Loan, does not exceed the total estimated cost of attendance. Dependent undergraduate students (excluding students whose parents cannot borrow Parent PLUS loans) may borrow Stafford Loan amounts not to exceed an annual total of • $5,500 for first-year students, with no more than $3,500 in subsidized Stafford; • $6,500 for second-year students, with no more than $4,500 in subsidized Stafford; and • $7,500 for third- and fourth-year students, with no more than $5,500 in subsidized Stafford. Independent undergraduate students and dependent undergraduate students whose parents are unable to borrow Parent PLUS loans may borrow additional unsubsidized Stafford Loan amounts not to exceed an annual total of • $9,500 for first-year students, with no more than $3,500 in subsidized Stafford; • $10,500 for second-year students, with no more than $4,500 in subsidized Stafford; and • $12,500 for third- and fourth-year students, with no more than $5,500 in subsidized Stafford. Graduate students may borrow Stafford Loan unsubsidized amounts not to exceed an annual total of $20,500. The maximum outstanding total subsidized and unsubsidized Stafford Loan debt is Information for Undergraduate Students • $31,000 for dependent undergraduate students, with no more than $23,000 in subsidized Stafford; • $57,500 for independent undergraduate students (or for dependent undergraduate students whose parents do not qualify for PLUS loans), with no more than $23,000 of this aggregate amount in the form of subsidized loans; and • $138,500 for graduate students (including loans for undergraduate study), with no more than $65,500 of this aggregate in the form of subsidized loans. Stafford Loan interest rates The interest rate on subsidized and unsubsidized Stafford Loans disbursed for enrollment periods that begin after July 1, 2022 is currently scheduled to be fixed at 4.99% for undergraduate students.

Direct Stafford Loans have a six-month grace period that starts the day after the borrower graduates, leaves school, or drops below half-time enrollment. Repayment begins when the grace period ends. Deferments are available for new borrowers during at least half-time enrollment at an eligible institution; during periods of academic study in approved graduate fellowship or rehabilitation programs; and for periods of unemployment and economic hardship. Information for Undergraduate Students Applications for Federal Direct Stafford Loans are available on the Caltech Financial Aid Office website. Complete information on Stafford Loan deferments and repayment options is also available from the Financial Aid Office FEDERAL PARENT PLUS LOAN Parent PLUS loans are available to the parents or stepparents of dependent undergraduate students. These credit-based loans are not based on federal need or subsidized by the government, but students must file a FAFSA in order for their parents to qualify for a Parent PLUS loan. Interest is charged on Direct Parent PLUS loans during all periods, beginning on the date of the loan's first disbursement. There is no annual limit to the amount that can be borrowed through the Parent PLUS loan program. In general, parents may borrow the difference between the cost of the student's education and any other financial aid received. PLUS loans may also be used to pay for all or part of the expected family contribution. In addition to the interest, parents pay a loan fee.

Specifically, Parent PLUS loan borrowers may defer repayment while the dependent student on whose behalf the loan was obtained is enrolled on at least a half-time basis, and during the six-month period after the dependent student on whose behalf the loan was obtained ceases to be enrolled on at least a half-time basis. If a Parent PLUS loan borrower does not request a deferment, the first payment on the loan will be due within 60 days after the loan is fully disbursed. Applications for Federal Direct Parent PLUS loans are available on the Caltech Financial Aid Office website. Applications must be submitted to the Financial Aid Office for eligibility certification. Complete information on Parent PLUS loan deferments and repayment options is also available from the Financial Aid Office. Federal Student Aid Ombudsman The Federal Student Aid Ombudsman works with student loan borrowers to informally resolve loan disputes and problems. The office of the ombudsman helps borrowers having problems with the following federal loans: direct loans (subsidized and unsubsidized Direct Stafford Loans, Direct PLUS loans, and Direct Consolidation Loans); Federal Family Education Loans (subsidized and unsubsidized Stafford Loans, FFEL PLUS loans, and FFEL Consolidation Loans); guaranteed student loans, SLS loans, and Federal Perkins Loans. If a student needs the assistance of the ombudsman in order to resolve disputes or problems, they may contact the office at U.S. Department of Education, FSA Ombudsman Group, 830 First Street, N.E., Mail Stop 5144, Washington, D. C. 20202-5144; (877) 557-2575 (Best used to initiate a Case) TDD: (202) 377-3800; fax: (202) 275-0549; Email: fsaombudsmanoffice@ed.gov; visit the website at studentaid.gov/feedback-ombudsman/disputes to submit a complaint. Information for Undergraduate Students Caltech Loans Generally, no interest is charged and no repayment of principal is required while a student maintains a continuous course of study at Caltech. Repayment on Caltech loans begins nine months after graduation, leaving school, or less than half-time enrollment. Caltech loans carry an annual interest rate of 5%. More specific information is provided on the promissory note and the disclosure statement provided to students prior to disbursement of the loan. Other loans/emergency loans may be available to students regardless of their eligibility for financial aid. These loans are usually payable within the same academic year and are administered by the dean of students on a case-by-case basis. Additional information and applications may be obtained from the dean of students' office. The Dean's Office also has a no-interest, 30-day emergency-loan program. Maximum loans are $500. Additional information and applications may be obtained from the Dean's Office. STUDENT EMPLOYMENT Work programs provide students with the opportunity to earn money to help with college expenses while gaining valuable job experience. Student employment opportunities are generally available to all Caltech students, even those who have not applied for financial aid or qualified for need-based aid. On campus employers are encouraged to post opportunities through Career Advising and Experiential Learning's platform. Please note that students may work no more than 16 hours per week (no more than 12 hours per week as undergraduate teaching assistants). Undergraduate TAs must be in good academic standing (eligible, and not on probation), and good disciplinary standing (not on disciplinary probation) for the term in which they are serving as a TA, and must be approved by the undergraduate deans. First-year students may not work during fall term. Students can expect to earn at least the City of Pasadena minimum wage of $16.11 per hour. Compensation rates will vary based on the position, a student's skills, and previous work experience. Additional policies and procedures for teaching assistants, including undergraduates with teaching responsibilities are included in the Information for Graduate Students section, Teaching Assistantships. Federal Work-Study Awarded to domestic students who have demonstrated financial need through their submission of the FAFSA, this federally funded program provides part-time employment to eligible students. Most Caltech students are awarded $2,500 in Federal Work-Study (FWS). Some students may be awarded less. Since entering students are not permitted to work on-campus in the fall term and can only work in the winter and spring terms, student employment awards for entering students are limited to $1,350 in their first year. Employment awards will increase to the standard student employment amount offered to continuing students after the first year. The maximum Financial Aid 231 232 amount of FWS wages that a student may earn is determined by their financial need. Students have the option to move all or a portion of their loan or student employment from one program to the other at any time during the academic year. The final day to request to convert your loan into work or work into loan is one day after the beginning of the registration period for the term following your last term of enrollment for the year. Please use the following table to determine which deadline applies to you. Last Term of Enrollment in Academic Year 2022-23 Fall Term Winter Term Spring Term Hard Deadline November 18, 2022 February 24, 2023 May 26, 2023 Please go to the work-study page on the Caltech Financial Aid Office website (finaid.caltech.edu/TypesofAid/workstudy) for additional information about student employment at Caltech. Caltech Work-Study The Caltech Work-Study Program is funded by the Institute and is designed to provide part-time employment for international students who have demonstrated financial need, and other students who do not qualify for the Federal Work-Study Program. The Caltech Work-Study Program is limited to on-campus employment or student employment positions at the Jet Propulsion Laboratory. The program's regulations parallel the Federal Work-Study Program's regulations. FINANCIAL AID WHEN STUDYING ABROAD/AWAY Caltech provides student financial aid (in the form of grants, scholarships, and loans) to those undergraduates with demonstrated financial need who desire to participate in the Institute-sponsored University of Chicago Study Away Program, Caltech Cambridge Scholars Program, Caltech Copenhagen Scholars Program, Caltech Edinburgh Scholars Program, École Polytechnique Scholars Program, Caltech London Scholars Program, or Melbourne Scholars Program. Enrollment in a study-abroad program approved for credit by Caltech will be considered enrollment at the Institute, for the purpose of applying for and receiving federal student financial assistance. To be eligible for consideration in Caltech's study-abroad programs, students must be in good academic standing, as defined in the Caltech Catalog and as certified by the Institute's registrar. They must also meet the minimum GPA requirement as outlined in the information provided by the Fellowships Advising and Study Abroad Office. In addition, students selected to be Cambridge, Copenhagen, École Polytechnique, Melbourne, or University College London scholars will be provided a memo of understanding outlining the terms of their study-abroad participation. (Check out Study Abroad.) Information for Undergraduate Students Costs include but are not limited to tuition, fees, room, board, additional meals not covered by a board contract, books, supplies, personal expenses, and a standard transportation allowance from the student's home to Caltech. Transportation expenses related to the student's travel between Caltech and the study-abroad institution are the responsibility of the student; financial aid recipients may be offered interest-free Institute loans to cover study-abroad travel expenses. Students will have their expected family contribution and financial package calculated in the same manner as other students. Students studying abroad are subject to the standard Caltech policy of a maximum of 12 terms of eligibility for financial aid. University of Chicago Study Away Program, Cambridge, Copenhagen, University College London, École Polytechnique, University of Edinburgh, and Melbourne University candidates must meet all financial aid priority deadlines and eligibility requirements to receive aid. It is the student's responsibility to ensure that all necessary documents are filed and complete with regard to their application for financial aid. University of Chicago Study Away Program participants and Cambridge, Copenhagen, University College London, Ecole Polytechnique, University of Edinburgh, and University of Melbourne Scholars will continue to be considered for available federal, state, Caltech grant, scholarship, and loan funds. The Fellowships Advising and Study Abroad Office will make the necessary arrangements with the Bursar's Office to ensure that scholars who may be eligible for funds in excess of the direct charges to the Institute receive those funds prior to their departure. OTHER RESOURCES A number of both local and national organizations offer outside scholarships to continuing students throughout the year, some of these regardless of need. Those relevant to undergraduate students will also be posted on the Caltech Financial Aid Office website. Such scholarships can also often be found with the help of a search service. We recommend College Board Fund Finder (bigfuture.collegeboard.org/scholarship-search); CollegeNet Mach 25 (scholarshipopportunity.org/collegenetmach-25/); FastWeb (fastweb.com); Scholarship Guidance (scholarshipguidance.com/; Scholarship Opportunities for Women (affordablecollegesonline.org/womens-guide-paying-for-college/); Scholarship Opportunities for Minority Students (affordablecollegesonline.org/financial-aid-for-minorities/; and Scholarship Search by Sallie Mae (salliemae.com/college-planning/too Is/scholarship-search/?dtd cell=SMPLSHDCOTDOBOOTOTHOTHRR 010001). (For more information on scholarship services, go to finaid.org). You may also visit the Financial Aid website at finaid.caltech.edu/TypesofAid/OS/list for a list of outside scholarships. Outside scholarships acquired by students are considered, by federal regulation, to be a resource available during the academic year. Caltech's policy is to use outside scholarships to replace the student employment and/or loan components of the financial aid package. For entering students, we generally replace student Financial Aid 233 234 employment first. For continuing students, loans are generally replaced first. Only if the total outside scholarships exceeds the student employment and/or loan that would have been included in your financial aid package will it be necessary to reduce Caltech scholarship. In general, a student's total financial aid, including outside assistance, cannot exceed their demonstrated financial need. Under no circumstances can a student's total financial aid, exceed their estimated cost of attendance. FINANCIAL AID DISBURSEMENT Most financial aid funds are credited directly to your student account and are applied first to institutional charges for the current term. Funds are credited no earlier than 10 days prior to the first day of the term. Aid that can be credited directly to your account will be credited when you have accepted or declined your awards on access.caltech; • provided all required documents for the aid programs you have been awarded made satisfactory academic progress; enrolled in at least the minimum number of credits for the financial aid programs you have been awarded; • completed all necessary loan documents and, for first-time Direct Stafford Loan borrowers, completed the online Entrance Interview. If the disbursement of aid results in a credit balance, any aid awarded in excess of institutional charges will be paid to the student as a refund. Refunds must be requested by the account holder. Requests may be made by e-mail, telephone, or in person at the Bursar's Office. Prior to receiving funds, it may be necessary to fill out and sign a refund form. Refunds can be obtained in cash or by check. A maximum refund of $500 cash per day can be received from the Bursar's Office cashier. Refund checks are requested by the Bursar's Office and issued by Accounts Payable. This usually takes five working days from the day of request. Outside scholarships are usually disbursed in the form of a check and must be handled according to the sponsor's specifications. If the funds are sent to the Financial Aid Office or the Bursar's Office, they will be credited to your account. Again, if the crediting of any outside scholarship results in a credit balance on your account, you may request that the credit balance be refunded to you. Federal regulations allow Caltech to credit financial aid funds to your account for payment of tuition, fees, and room and board charges. You must give the Bursar's Office written authorization to keep a credit balance on your account from one term to the next term during the academic year. Federal guidelines prohibit keeping a credit balance from one academic year to the next. If you complete your financial aid file late in the term, resulting in the late disbursement of your financial aid funds, you may be subject to late fees assessed by the Bursar's Office. Cal Grant B stipend payments will be credited to your tuition account unless you contact the Financial Aid Office in person within Information for Undergraduate Students the first three weeks of the term to make alternate arrangements. Again, if the crediting of any financial aid results in a credit balance on your account, you may request that the credit balance be refunded to In general, loans are disbursed in three installments, one at the beginning each term. For most Caltech students who are enrolled for the full academic year, this means that one-third of their loan(s) will be disbursed at the beginning of the fall term, another at the beginning of the winter term, and the final third at the beginning of the spring term. Students whose loan periods are for one term receive their entire disbursement at the beginning of that term. If you work through either the Federal Work-Study or the Caltech Work-Study program, you will be paid by check through the biweekly Caltech payroll system. Checks are normally distributed at your actual work site. Since financial aid is generally awarded on the assumption of full-time enrollment, it is possible that some or all of your aid will need to be adjusted if your enrollment status results in a reduction in your tuition for a term. If you withdraw or drop below half-time enrollment after the last day for adding classes for a term, you may be required to repay all or a portion of the aid that has already been credited to your account. You must inform the Financial Aid Office if you take a leave of absence or change your enrollment subsequent to receiving your financial aid. Cal Grant recipients who take a leave of absence are advised to contact the California Student Aid Commission (csac.ca.gov) and submit a form to remain eligible for the program. You have the right to cancel your loan(s) any time before disbursement and up to 14 days after disbursement. SATISFACTORY ACADEMIC PROGRESS (SAP) Federal and state regulations governing student financial aid programs require the Institute to ensure that each student who is receiving financial aid maintains Satisfactory Academic Progress (SAP) toward their degree. The SAP check occurs after grades are posted at the end of each term. Failure to meet the standards of satisfactory academic progress may disqualify a student from additional federal, state and institutional financial aid. A student can appeal their unsatisfactory academic progress status and be placed on warning, probation or continued on probation for financial aid purposes. Satisfactory Academic Progress Requirements Following the first two terms, which are taken on a pass-fail basis, first-year students will be ineligible to register if they failed to pass at least 27 units in the previous term. After the first two terms of study, all undergraduate students must complete a minimum of 27 units with a grade-point average of at least 1.9 in order to remain eligible to register for classes. In addition, students must earn an average of 36 units per term over the past three trailing terms (that is, a minimum of 108 units should be earned after three terms of enrollment each academic year). A student may be excused from the 27-unit eligibility Financial Aid 235 236 requirement if the requisite petition has been approved, prior to Add Day, by the dean or associate dean of undergraduate students. Under exceptional circumstances the deans may waive the requirement that such a petition be approved prior to Add Day, but may do so only once during that student's career at Caltech. Following their first ineligibility, students are to meet with the dean or associate dean of undergraduate students. The dean may choose to reinstate them, in which case they will be on academic probation. Alternatively, the dean may direct them to petition the Undergraduate Academic Standards and Honors Committee (UASH) for reinstatement. UASH will either approve their petition for reinstatement and place them on academic probation, or require them to withdraw from the Institute for at least two terms. Students who fail a core course or who fail to successfully complete 36 units, even though they remain in good standing, are required to meet with one of the undergraduate deans before being allowed to register for classes in the subsequent term. Financial Aid Warning Students who are found not to be making satisfactory academic progress at the end of an academic term will be placed on financial aid warning. A student may continue to receive financial aid for one term while on financial aid warning status. Students should use this opportunity to re-establish SAP. Financial Aid Probation Students who fail to make satisfactory academic progress after their term of financial aid warning will be ineligible to register and ineligible for financial aid. Students may appeal this status as outlined in the Caltech Catalog. Ineligible first-year students must petition the UASH Committee for reinstatement if they wish to continue as students and continue to receive financial aid. The dean of students or associate dean may act on a petition if it is the student's first ineligibility. Undergraduate students, except first- and second-term first-year students, may submit a petition to the UASH Committee for reinstatement, giving any reasons that may exist for their previous unsatisfactory work and stating any new conditions that may lead to better results. Each such petition will be considered on its merits. For the first such ineligibility, the petition may be acted on by the dean of undergraduate students, after consultation with the student and examination of the record. At the dean's discretion, such cases may be referred to the UASH Committee for action. All subsequent reinstatements must be acted upon by the Committee. Students who are reinstated as a result of their appeal/petition for reinstatement will be placed on financial aid probation and may receive financial aid for an additional academic term. Information for Undergraduate Students Continued on Financial Aid Probation Students who fail to make satisfactory academic progress after a term on financial aid probation will be ineligible to register and ineligible for federal and state financial aid. These students may appeal this status as outlined above and in the Caltech Catalog. Students who are reinstated as a result of their appeal/petition for reinstatement will be continued on financial aid probation. These students will be ineligible for federal and state aid. They will continue to be eligible for up to three additional terms of institutional aid but their scholarship eligibility will be reduced in each term the student is continued on financial aid probation. Financial Aid Suspension Students who fail to make satisfactory academic progress after being continued on financial aid probation for three additional terms will be ineligible for federal, state and institutional financial aid, even if they are subsequently reinstated by the UASH Committee, until such time as they make satisfactory academic progress. Maximum Time Frame for Receiving Aid A student has a limited time frame to complete all degree requirements and remain eligible for financial aid. As defined by federal regulations, the maximum time frame is 150 percent of the published program length for degree completion. To qualify for a Bachelor of Science degree, students must complete a minimum of 486 units -> 486 × 150% = 729 maximum attempted units. An "attempted" unit is defined as any unit that a student remains enrolled in AFTER the Add Period, including units the student withdraws from each term. Units that a student is retroactively enrolled in after the Add Period are considered attempted units. CLASS LEVEL FOR FINANCIAL AID PURPOSES Undergraduate students are classified according to the number of units earned and the number of terms in residence at Caltech. Both these criteria must be satisfied for class-level eligibility. Students are regarded as first-year until eligible for sophomore status, and as sophomores, juniors, or seniors if they meet the corresponding criteria set below. Units earned are defined as units completed with a passing grade. Classification Minimum Units Earned Minimum Terms in Residence Sophomore 108 3 Junior 216 6 Senior 324 9 Financial Aid 237 238 PART-TIME ENROLLMENT (UNDERLOADS) The Institute will charge students for a minimum of 12 terms of full-time tuition, or the prorated equivalent based on their classification at the time they begin their enrollment, even if they complete their degree requirements early. Undergraduate students who underload in a term will be charged full-time tuition but their financial aid, including outside scholarships, will be adjusted as indicated below based on the actual number of units students are enrolled in as of Add Day. Students may NOT receive scholarship assistance for any term in which they are not enrolled at least half-time. Underloads and Financial Aid: The Impact of Less than Full-time Enrollment Any student who wishes to carry fewer than 36 units in any given term must petition for an underload. Underloads must be approved by the Dean or Associate Dean of Undergraduate Students. Underloads for graduating seniors must be approved by the Registrar. (See the underload policy.) The following information summarizes the impact of less than full-time enrollment on financial aid. For the separate conditions regarding eligibility see enrolled less than full-time. 3/4 Time Full-time enrollment is defined in the Caltech Catalog as 36 units. Students enrolling less than full-time, taking between 27 to 35 units, are considered enrolled 3/4 time. The impact to their financial aid is usually a reduction to their grant, in the same amount as the reduction in their tuition. Federal Pell Grant recipients will have their Federal Pell award reduced according to federal regulations. The Financial Aid Office will revise the student's budget to reflect the calculated per-unit tuition and then revise the student's aid (grant eligibility) to reflect the reduction in calculated need. 1/2 Time Half-time enrollment is defined as enrolling in 18 to 26 units. In this situation, the Financial Aid Office will revise the budget for financial aid purposes to reflect the calculated per-unit tuition and reduce the books and supplies allowance to 1/2 of the standard amount for that term. Federal Pell Grant recipients will have their Pell award reduced according to federal regulations. The Financial Aid Office will revise the student's budget to reflect the per-unit tuition and other reductions in education related costs and then revise the student's aid (grant eligibility to reflect the reduction in calculated need. Students enrolled 1/2 time can also anticipate an increase in their work-study award for the term. Information for Undergraduate Students Less than 1/2 Time Less than 1/2 time enrollment is defined as taking fewer than 18 units. Tuition is revised for financial aid purposes to reflect the calculated per-unit tuition and the books and supplies allowance is reduced to 1/4 of the standard allowance for that term. (As indicated in the Caltech Catalog, the minimum tuition charge is units per term.) The student's aid is revised based on the reduced education related costs. Federal Pell Grant recipients will have their Pell award reduced according to federal regulations. More importantly, the student/family becomes ineligible for scholarship/grant aid awarded by Caltech and for Federal Direct PLUS or Stafford loans for that term. The student is only eligible for Caltech work-study and loan assistance. Please note: If the student is enrolled less than half time, the grace period on any student loan (Federal Perkins Loan, Federal Direct Stafford Loan and Caltech and Institute loans) will begin. Effect on Outside Scholarships In all of the above categories, the Financial Aid Office also checks to see if a student has an outside scholarship that requires continuous full-time enrollment. If a scholarship donor requires full time enrollment, the Financial Aid Office is required to return the scholarship money for that term to the donor. If this occurs, the student is encouraged to contact the donor directly to review and, possibly, appeal the agency's policy. Questions Students with questions regarding underloads should discuss their individual circumstances with a financial aid administrator. Contact the office Monday through Friday from 8 a.m. to 5 p.m., with any questions you have.

GRADUATION REQUIREMENTS, ALL OPTIONS To qualify for a Bachelor of Science degree at the Institute, students must obtain passing grades in each of the required courses listed below; must satisfy the additional requirements listed under the undergraduate options; must complete a minimum of 486 units; and must achieve a grade-point average of not less than 1.9. Students must also register for the appropriate number of units that results in normal progress toward a B.S. degree. The baccalaureate degree requires four years (12 terms) of residence regardless of unit load each term or the total units earned. The four-year residence requirement is separate from and in addition to any other degree requirements. Students who are admitted as transfer students or 3/2 students may be granted advanced standing and tuition credit for academic work accepted in transfer to Caltech. Information for Undergraduate Students However, transfer and 3/2 students must enroll for a minimum of six terms at Caltech. Any exceptions must be approved by the dean of undergraduate students and the vice president for student affairs. Under normal circumstances the core and option requirements for the B.S. degree are those stated in the catalog published in the first year of a student's enrollment at Caltech. Faculty actions or decisions taken through the Faculty Board and the relevant faculty committees may occasionally result in changes to these requirements. In the event of exceptional circumstances, changes in an individual student's graduation requirements may be sought by petition to the relevant Faculty Representatives) through procedures administered by the registrar. Questions should be addressed to the registrar. Students must register for the Institute requirements in the year specified, unless they have previous credit. If for some reason they are not able to complete the requirements during the proper year, they must register at the earliest possible opportunity. (The Curriculum Committee may in unusual cases excuse undergraduate students from any of the following Institute or option requirements upon presentation of petitions.) The Institute unit system is described in the opening paragraphs of section five of this catalog. CORE INSTITUTE REQUIREMENTS, ALL OPTIONS A Caltech education requires not just the depth of an option, but also considerable breadth in basic science, humanities, and social science. Caltech's core curriculum prepares students for the interdisciplinary nature of contemporary research in science and technology. This encourages a culture of problem solving, collaboration, and communication while providing valuable experience in all fields of science. Significant study in the humanities and social sciences is an important component of Caltech's core curriculum, giving alumni the ability to navigate the societal, political, and economic factors that influence, and are influenced by, their work. The following requirements are applicable to incoming first-year students for 2022-23. Some information for continuing students has been provided as footnotes, but guidance on special cases must be sought. Courses used to satisfy core requirements may not be used to satisfy option electives. Courses Units 1. First-Year Mathematics (Ma 1 abc) 27 2. First-Year Physics (Ph 1 abc) 27 3. First-Year Chemistry (Ch 1 ab) 15 4. First-Year Biology (Any Bi 1 course or Bi 8 and Bi 9)' 5. Menu Class (currently Ay 1, EE 1, ESE 1, Ge 1, or IST 4) 9 6. First-Year Chemistry Laboratory (Ch 3 a)? 6 Graduation Requirements, All Options 249 7. Additional Introductory Laboratory 6 8. Scientific Writing3 3 9. Humanities Courses (as defined below) 36 10. Social Sciences Courses (as defined below) 36 11. Additional Humanities and Social Sciences Courses 36 12. Physical Education 9 ' The biology core requirement can be met by any Bi 1 course. Alternatively, the requirement may be fulfilled by taking both Bi 8 and Bi 9. Nine units must be taken on grades. This requirement can also be met by completing Ch 3 x, Ch 4 a, Ch 8, or Ch/ChE 9. 3 This requirement may be met either by taking a course approved by the student's option to satisfy this requirement, or by taking En/Wr 250 Menu Classes Menu classes are specifically designed for breadth. The intent of the menu class requirement is to introduce students to a subject that they did not plan to study. In many cases, it is the only class in that subject that they ever take; in other cases, they may decide to take more classes in that subject as a result. Students cannot take a menu class in a subject that they have already taken classes in or in their current option. This requirement must be completed by the end of sophomore year. First-Year Biology Requirement All students are required to take 9 units of first-year biology, which can be satisfied by taking any course numbered Bi 1. Several different course options are available, with each Bi 1 course representing a different approach to providing an introductory understanding of the biological sciences. Bi 1 courses are offered in different terms (for 2022-23, they are offered in winter and spring terms; for 2023-24 we anticipate offering them in all three terms). All Bi 1 courses may be taken pass/fail if they are taken in a first-year student's first year, independent of the term in which the course is taken. For students who are interested in a more in-depth introduction to biology, the first-year biology requirement can also be satisfied by completing both Bi 8 and Bi 9. Introductory Laboratory Requirement All students are required to take at least 12 units of laboratory work in experimental science during their first-year and sophomore years. Ch 3 a (6 units) or Ch 3 x (6 units) shall be taken during the first year. The additional 6 units must be chosen from one of the following: APh/EE 9 (6 units), APh/EE 24 (9 units), Bi 1x (9 units but only if Bi 1x is not being used to satisfy the biology core requirement), Bi 10 (6 units), Ch 4 ab (9 units), Ch 8 (9 units), Ch/ChE 9 (9 units), EE/ME 7 (6 units), Ge 116 (9 units), ME 8 (6 units), Ph 3 (6 units), Ph 5 (9 units), Ph 8 bc (6 units), or Information for Undergraduate Students a more advanced laboratory. Computational laboratory courses may not be used to satisfy this requirement. Humanities and Social Sciences Requirements All students must complete satisfactorily 108 units in the Division of the Humanities and Social Sciences. Of these, 36 must be in the humanities (English, history, history and philosophy of science, humanities, music, philosophy, and visual culture) and 36 in the social sciences (anthropology, business economics and management, economics, law, political science, psychology, and social science), in each case divided equally between introductory and advanced courses. The remaining 36 may be drawn from humanities and social sciences, including HSS tutorial courses and 9 units of either Wr 1 or Wr 2. They may not include BEM 102. They may not include reading courses unless credit has been granted by petition to the humanities or social science faculty. Language courses may count toward the additional 36 unit requirement, with the exception of beginning, intermediate, and advanced classes in the student's native language. In general, no more than 18 units of first-year humanities may be counted toward the 108-unit requirement. Entering first-year students are required to take two terms of first-year humanities; that is, cross-listed humanities courses numbered 60 or below in the Catalog. These classes introduce students to the basic issues and methods in the disciplines of English, history, philosophy, and visual culture. Successful completion of two terms of first-year humanities is a prerequisite for all humanities courses, except for foreign languages. It is not a prerequisite, however, for introductory social sciences. The first-year humanities classes may be taken in any two terms of the first year. To encourage breadth, students will have to take their two first-year humanities courses in different disciplines, the disciplines being English, history, philosophy, and visual culture. A student must take 18 units of advanced humanities courses as well. The classes that count as advanced humanities courses are those numbered 90 or above in English, history, history and philosophy of science, humanities, music, philosophy, and visual culture. Language courses do not count toward the advanced humanities requirement, except for courses that are cross-listed or taught concurrently with one of the listed subjects, such as humanities or visual culture. Courses used to fulfill the advanced humanities requirement must be taken for grades. Courses taken on a pass/fail basis will not fulfill the requirement. Since writing is an important method for developing and sharing ideas, all first-year humanities courses and other humanities courses numbered above 90, with the exception of some foreign languages and courses, require at least 4,000 words of composition. Instructors give extensive feedback on written work and help students improve their prose. As entering students may not be fully prepared for the writing in first-year humanities, all first-year and transfer students take a writing assessment before the beginning of the fall term. On the basis of this assessment, some students may be required to pass WR Graduation Requirements, All Options 251 252 Introductory Course Following Course An 14, 15 or 16 advanced anthropology Ec 11 advanced economics or BEM (except BEM 102) PS 12 advanced political science Psy 13 advanced psychology 1, 2, 3, 4 and/or 50 before entering either first-year or advanced humanities classes. Students are required to take two introductory social science courses and 18 units of related advanced undergraduate social science courses. Courses used to fulfill the advanced social science requirement must be taken for grades; courses taken on a pass/fail basis will not fulfill the requirement. The introductory social science courses must be drawn from the following list: either An 14 or An 15 or An 16, Ec 11, PS 12, or Psy 13. The 18 units of advanced undergraduate social science courses (numbered 100 and above), in fields following at least one of their introductory courses, must be taken as indicated here: For instance, a student who has taken An 14 and Ec 11 may use 18 units of advanced anthropology courses, or 18 units of advanced economics, or 9 units of advanced anthropology and 9 units of advanced economics to fulfill the advanced social science requirement. Included in the 12 humanities and social science courses, students must take at least 3 writing-intensive courses and these must be taken on grades. The graded advanced humanities courses count towards this total. A student can select another course from advanced humanities or a social science course with writing content (specifically An/PS 127, Ec 105, Ec 129, Ec 130, Ec 140, PS 99 ab, PS 120, PS 123, or PS 141). These three writing-intensive courses should be spread out over the student's sophomore, junior, and senior years. Physical Education Requirement Before graduation, each undergraduate is required to successfully complete 9 units of physical education. This requirement may be satisfied entirely or in part by participation in intercollegiate athletics, or successful completion of physical education class course work. All grades are issued pass/fail. A maximum of 6 units per term may be applied toward graduation requirements, with the total not to exceed 36 units. Participation as a bona fide member of an intercollegiate team for the period covered by the sport in a given term satisfies the requirement for that term. A broad program of instruction is provided each term. Late registration is permitted during the first week of each term, provided there is space available and with permission of the instructor. Standards for evaluation of student performance will be clearly defined Information for Undergraduate Students at the beginning of each course. Scientific Writing Requirement The scientific writing requirement can be satisfied by taking an appropriate course offered by any division, or by taking En/Wr 84. The course used to satisfy this requirement must be taken on grades. All options also require a three-unit course in oral communication. Some options combine these two requirements into one course. At the discretion of the option, the scientific writing requirement can be satisfied by three units of additional work associated with a senior thesis, focused on effective written scientific communication.

These courses are offered third quarter only. It is also possible to take one of these courses as an elective. Menu courses currently include Ay 1, EE 1, ESE 1, Ge 1, or IST 4 4 Three terms (9 units) of PE are required for the B.S. degree. Students need not elect to take the required PE in the first year. It may be taken in any three terms before graduation. OTHER FIRST-YEAR COURSES In addition to the required core classes described on the previous pages, first-year students are encouraged to participate in first-year seminar classes, frontier classes, research tutorials and other research opportunities. Starting in the 2011-12 academic year, Caltech began offering a series of seminars for first-year students in which 10 to 15 first-year students and a faculty member explore in depth an exciting topic in the lab, around a table, or in the field. These courses cover a wide range of topics, including earthquakes, gravitational waves, and the science of music. Instructors may allow upperclassmen to enroll in these seminars after the conclusion of the pre-registration period for the upcoming term. See section on First-Year Seminars for more information. Caltech also offers a series of "frontier courses" that involve a weekly presentation by a faculty member on a topic of current research. These courses often meet at lunch time and serve pizza; hence, students refer to the courses as "pizza courses." The frontier courses are an opportunity for students to meet the Caltech faculty and to hear about state-of-the-art research projects for the summer or academic year. There are a total of 10 frontier courses offered for first-year students in biology, chemistry, mathematics, physics, geology and planetary sciences, engineering, computer science, chemical engineering, bioengineering, and electrical engineering. Currently there are three "research tutorials" for first-year students: one in physics, one in biology, and one in chemistry. These tutorials have many of the same features as the first-year seminars. In physics, the research tutorial includes approximately seven first-year students and extends over three academic terms plus the summer. The purpose is to demonstrate how research opportunities arise, are evaluated, and are tested, and how the ideas that survive develop in larger projects. In biology and chemistry, the tutorials are offered in the winter and spring quarters and involve small group discussions on special areas or problems in biology, biotechnology, and chemistry. More than 80 percent of Caltech students participate in research at some point in their academic career. Students may embark on research activities by registering for research credits with a faculty member, by working in a laboratory for pay during the summer or Graduation Requirements, All Options 255 256 academic year, by completing a senior thesis, or by participating in Caltech's Summer Undergraduate Research Fellowship (SURF) program. The SURF program is described Undergraduate Programs and Research. AEROSPACE MINOR (AE) The aerospace minor is intended to supplement one of Caltech's undergraduate degrees and is designed for students who wish to broaden their knowledge beyond their normal major or who may wish to pursue a graduate program involving aerospace or aeronautical engineering. Students completing the aerospace minor requirements will have the phrase "minor in aerospace engineering" added to their transcripts. Ae Minor Requirements 1. Complete Ae 105 abc. 2. Complete a second three-term 100-level Ae class, chosen from Ae 101 abc, 102 abc, 104 abc, 121 abc, Ae/Ge/ME 160 ab, or 27 units of selected Ae courses approved by the minor adviser. All Ae courses to be applied to fulfill the aerospace minor requirements must be taken for grades, and students must maintain an average grade of B or higher for all courses with no individual grade lower than a C. Courses that are used to satisfy the aerospace minor cannot be used to satisfy course requirements in the major options. Courses taken as part of the aerospace minor are counted toward the total 486-unit Institute graduation requirements. A typical course sequence would be to take Ae 105 abc and the second Ae course in the senior year. APPLIED AND COMPUTATIONAL MATHEMATICS (ACM) The undergraduate option in applied and computational mathematics within the Computing & Mathematical Sciences department seeks to address the interests of those students who want to combine their basic studies in mathematics with considerable involvement in applications. This program is designed to give students a thorough training in fundamental computational and applied mathematics and to develop their research ability in a specific application field. The fields of application include a wide range of areas such as fluid mechanics, materials science, and mathematical biology, engineering applications, image processing, and mathematical finance. The training essential for future careers in applied mathematics in academia, national laboratories, or in industry is provided, especially when combined with graduate work, by successful completion of the requirements for an undergraduate degree in applied and computational mathematics. Complete programs will be worked out with faculty advisers. ACM Double Majors Students interested in simultaneously pursuing a degree in a second option must fulfill all the requirements of the ACM option. Classes cannot be counted towards both options unless specifically required by both. To enroll in the program, the student should meet and discuss their plans with the option representative. In general, Information for Undergraduate Students approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load.

ASTROPHYSICS OPTION AND MINOR (AY) With the goal of understanding the physical processes that govern the universe, its constituents, and their origins and evolution, astronomy uses the apparatus and methodology of physics to gather and interpret data. Theoretical work and technology development round out astrophysics. In what follows, we use the terms "astronomy" and "astrophysics" interchangeably. The astrophysics option is designed to give the student an understanding of the basic facts and concepts of astronomy today, to stimulate their interest in research, and to provide a basis for graduate work in astronomy/astrophysics. Undergraduate Information Students petitioning to double-major in Astrophysics and Physics must present a plan that has a minimum of 92 units that are solely counted as satisfying the Ay requirements, and a minimum of 92 units that are solely counted as satisfying the Ph requirements. Attention is called to the fact that any student whose grade-point average is less than 1.9 at the end of an academic year in the subjects listed in the Division of Physics, Mathematics and Astronomy may, at the discretion of their department, be refused permission to continue the work in this option. Ay Option Requirements 1. Ay 20, 21, 101, 102, 30 or one term of Ay 141, Ay 31, Ma 2, Ма 3, Ph 2 abc or Ph 12 abc, Ph 125 ab, and Ph 106 abc. 2. Any three of Ph 3 or Ph 8bc, Ph5, Ph6, Ph7, or Ay 105. APh 23 and 24 taken as a pair may be substituted for one of these labs. 3. 63 additional units of Ay or Ph courses. Ph 127 a, Ph 136 bc and one of Ph 21, Ph 22, Ph 121 abc are strongly recommended. 4. 27 additional units of science or engineering electives, of which 18 must be outside the Division of Physics, Mathematics and Astronomy. ACM 95 ab is a popular choice. Core classes or other introductory-level courses such as CS 1 do not count toward fulfillment of this requirement. 5. Passing grades must be earned in a total of 486 units, including the courses listed above. Courses satisfying requirements 1, 2, and 3 must be taken for grades unless they are pass/fail only.

Other courses may also be used. 3 Strongly recommended courses for Option Requirement 3. Other courses may be substituted. 4 Phys 125c is strongly recommended and can be counted towards Option Requirement 3. The sequence Ay 20, 21 constitutes a solid introduction to modern astrophysics, with more advanced courses (Ay 101, 102, plus Ay electives) taken in the junior and senior years. The course schedule above is an example leading to excellent preparation for graduate study, but it is also possible to fulfill the option requirements with a more diverse set of electives across options, and even to take Ay 20, 21 junior year and Ay 101, 102 senior year. In either scenario, it is desirable for a student to gain as broad a background as possible in related fields of science and engineering. An ability to present one's Information for Undergraduate Students work is vital to a successful career in any field. The oral communications requirement can be satisfied by presenting during a term of Ay 141, or with Ay 30. Ay 31 satisfies the written communication requirement. Students are encouraged (but not required) to undertake research leading to a senior thesis; credit for this work is provided through Ay 78 with the process and requirements fully described there. Non-thesis research credits may be earned through Ay 142 with a maximum of 9 units per term. Elective credit can be given for no more than 3 terms of Ay 142. Computational skills may be acquired through e.g. ACM 11, ACM 106, CS 2, CS 11, CS 21, CS 38, CS 121, CMS 155, Ph 20, Ph 21, Ph 121. Students are strongly advised to take advanced mathematical methods in ACM95 and Ph 129, and an advanced statistical physics or thermodynamics course such as Ph 127. Suggested Electives The student may elect any course offered in any division in a given term, provided that they have has the necessary prerequisites for that course. The following courses are useful to work in various fields of astronomy and astrophysics: ACM 95, ACM 106, APh 17, APh/EE 23/24, APh/EE 117, Ay 104, Ay 105, Ay 107, Ay 117, Ay 121-127, Ch 125 ab, EE 45, EE/Ae 157, Ge/Ay 11 c, Ge 103, Ge/Ch 128, Ge 131, Ge/Ay 132, 133, 137, Ge 141, Ma 4, Ma 112, ME 11, ME 12, Ph 20-22, Ph 77, 101, 121, 127, 129, 136, 137, 199, 236 (this is not necessarily a complete list). Ay Option Minor The Ay minor is expected to appeal to student interest in the field of astronomy that arises from overlap, not only with the most traditional area of physics, but with more recent and rapidly developing intersections of astronomy with e.g. computer science, certain aspects of engineering, chemistry, planetary science, and perhaps some day biology. Ay minor coursework is designed to prepare the capable student to undertake cross-disciplinary research involving astronomy. A firm basis for this is established with sophomore level physics and astronomy requirements. Junior year courses sample from among the Ay major requirements and electives. Both traditional theory courses and more hands-on practical training courses are available, with one course of each type recommended for breadth. Senior year features research and written presentation of the research, with additional electives encouraged. Courses taken in the minor option must be taken for grades (no P/F), except for Ay 142 which is offered as P/F only. Courses 100 and above can not be used to also satisfy requirements in the student's major option. Graduation Requirements, All Options 265 266 Ay Option Minor Requirements 1. Basis in physics: either Ph 2ab or Ph12 ab (18 units) 2. Introductory Astronomy: any two of Ge/Ay 11c, Ay 20, or Ay 21 (18 units) 3. In-depth Astrophysics, Instrumentation, and Data: any two of: Ay101, Ay 102, Ay 104, Ge/Ay 133, Ay 105, Ay/Ge 107, Ay 122 (18 units) 4. Research: both Ay 142 (9 units) and Ay 144 (3 units) = (12 units) Total units required: 66 Other courses of interest to students seeking Ay minor competency include Ay 119, Ay 198, Ay 141, Ph 2c/12c, Ph 101, EE 40, APh/EE 23. These do not contribute to credit for the minor, however. Course selection should be done in consultation with the Ay option representative, who can advise on an appropriate curriculum for a given student's goals. As a complement to the required Ay 142 enrollment, SURF research with the relevant Ay, Ph, or Pl.Sc. faculty member is encouraged. BIOENGINEERING OPTION (BE) BE Aims and Scope The undergraduate bioengineering option provides a foundation for graduate studies and career paths that require the application of engineering principles to the design, analysis, construction, and manipulation of biological systems, and in the discovery and application of new engineering principles inspired by the properties of biological systems. By graduation, students are expected to have learned basic laboratory and engineering methods used in a broad range of bioengineering sub-disciplines. Students will also have learned quantitative and analytic skills vital to experiments and system designs. Graduating students are expected to be able to critically evaluate and understand bioengineering literature, and be able to work in a team and communicate effectively. To accomplish these goals, students are expected to complete a series of required courses designed to introduce them to a representative range of bioengineering sub-disciplines, provide them with a solid quantitative analysis foundation, and provide them with opportunities to work in teams through a number of project-oriented courses. Students will receive instruction in scientific communications through Bi/BE 24. Undergraduate research is encouraged both during the academic year and through participation in summer research programs. Students should present a plan for satisfying all degree requirements to their academic adviser by the end of the third term of the second year. Students with a grade-point average lower than 1.9 will not be allowed to continue in the option except with special permission from the option representative.

The option serves as a basis for graduate study in any field of biology or for admission to the study of medicine. Instruction is offered in the form of participation in the ongoing research programs of the division, as well as in formal course work. Course work emphasizes the more general and fundamental properties of living organisms, and areas of current research interest, rather than the traditional distinct fields within the life sciences. The division encourages undergraduate participation in its research program and believes that research participation should be a part of each student's program of study. Students may elect to prepare an undergraduate thesis (Bi 90). Research opportunities may be arranged with individual faculty members, or guidance may be obtained from a student's individual faculty adviser in the division or from the biology Information for Undergraduate Students undergraduate student adviser. The requirements listed below for the biology option are minimal requirements. An adequate preparation for graduate work in biology will normally include additional elective research or course work in biology and/or advanced course work in other sciences or in mathematics. Flexibility to accommodate varied individual scientific interests, within the broad scope of biology, is achieved through the provision of elective courses, arrangements for individual research (Bi 22), and tutorial instruction (Bi 23). In addition, arrangements may be made to take courses at neighboring institutions in fields of biology that are not represented in our curriculum. Premedical Program The undergraduate course for premedical students is essentially the same as that for biology students and is intended as a basis for later careers in research as well as in the practice of medicine. It differs in some respects from premedical curricula of other schools; however, it has been quite generally accepted as satisfying admission requirements of medical schools. It is recommended that all students contemplating application to medical school consult with the premed adviser at Careers, Advising, and Experiential Learning or Professor Mitchell Guttman in the Division of Biology and Biological Engineering. Bi Option Requirements The following required courses must all be taken on grades, with the exception of Bi 8 if taken as a first-year student and Bi 22. First-year students taking Bi 8 must maintain shadow grades that indicate satisfactory progress. 1. Bi 8, Bi 9, Bi 117, Bi 122, NB/Bi/CNS 150, and Ch 41 abc. 2. Ma 2, Ma 3, and any two terms of Ph 2 abc. BE/Bi 25 can be taken in place of Ph 2 c. This requirement can also be satisfied in part by successfully taking a "reasonable" replacement for any of these required courses. A "reasonable" replacement will be defined by: (1) Equally or more advanced quantitative coursework, e.g. Ch 21 a for Ph 2 b, Ch 21 c for Ph 2 c and; (2) Essentially similar scope of subject matter as the course replaced. The Biology option representative will be empowered to make this determination with aid of an advisory list which can be updated as relevant new courses are developed inside and outside of biology. 3. One advanced laboratory course (100- or 200-level), or Bi 21 with presentation, or three terms of undergraduate thesis (Bi 90 abc). 4. Two courses chosen from Ch/Bi 110 a, 110 b, 111, and/or BMB/Bi/Ch 170, 173 or Ch 145. 5. Scientific writing requirement met by taking Bi/BE 24 (six units), or by taking any other writing course such as En/Wr 84 (nine units) plus oral presentation at SURF Seminar Day or equivalent, with option representative approval. Graduation Requirements, All Options 271 272 6. A minimum of 8 courses of biology electives must be taken. To count as a biology elective, a course must satisfy the following: a. The course is not used to satisfy requirement 1-5. b. 100-level or above. c. The course must be a biology or a bioengineering course. d. At least two elective courses must be nine units each, and must be taken for grades. e. A minimum total of four elective courses must be taken for grades. 7. Exceptions are as follow: a. Substantial lab research for credit (Bi 22) beyond the 12-unit minimum can be counted among the electives. b. Courses from other options with significant relevance to biology may be used as electives with permission from the biology option representative. 8. A minimum total of 170 units of biology must be taken and passed. Any Bi 1 course, Bi 2, Bi 10, and BE/Bi/CNS/NB 197 cannot be counted toward this total. Bioengineering courses used for electives can be counted toward this total. Passing grades must be earned in a total of 486 units, including the courses listed above. Planning the Biology Course Schedule • Most students interested in biology elect to take Bi8 and Big in their first year, to open access to the widest range of biology electives. • Bi 10 or Bilx is not required for the biology option but is commonly taken by biology students to meet the Institute introductory laboratory requirement. • Prerequisites listed for individual biology courses are advisory, not compulsory. They indicate the kind of background that is assumed for the work level of the course. They may be waived if the instructor gives explicit permission. • BE/Bi 25 is strongly recommended for students interested in postgraduate work in biology, as physical chemistry is required by most graduate programs. • Additional courses of potential interest to biology majors include Ge 11 b, BE 159, BE/Bi/APh 161, BE/ChE 163, BMB/Ch 178 and advanced geobiology courses. • Undergraduates are generally welcome to take 200-level courses with the instructor's permission or strong preparation, unless otherwise indicated.

Advanced Biology. 36 units of advanced biology electives (100-or 200-level) that are not applied to the above requirements and are not simultaneously used for fulfilling a requirement of the student's major option, approved by their assigned biology adviser or the option representative. BUSINESS, ECONOMICS, AND MANAGEMENT OPTION (BEM) The goal of the business, economics, and management (BEM) option is to provide students with the analytical tools to operate successfully in a modern business environment and to prepare students interested in pursuing graduate studies in related fields. The emphasis is on entrepreneurship, finance, and strategy, in free-market, competitive, and strategic situations. Today's business environment is complex, and therefore required courses in this option are highly analytical. Students often pair the BEM option as a double major with a science or engineering option. The BEM option also serves as a standalone major for students interested in careers in the financial industry, consulting, or entrepreneurial ventures. Expected learning outcomes from completing the BEM option include: .. a strong background in economic theory and econometrics; an understanding of the theoretical and practical aspects of finance, risk management, business strategy, and developing new ventures; • an ability to analyze business problems using qualitative and quantitative methods; • an ability to analyze financial and business data; • an ability to write and communicate effectively; and Graduation Requirements, All Options 277 278 • an understanding of the broader impacts of business and management on society in general. Note: The official source on requirements for graduation is the Caltech catalog from the year in which a student began studies at Caltech. Please see the catalog online, from this and previous years, for information regarding the applicable option requirements. BEM Option Requirements It is highly recommended to take a statistics/econometrics course, as well as BEM 102 and BEM 103 before other BEM courses. 1.

This is accomplished through a mixture of interdisciplinary classes that expose students to almost every field of science (chemistry, physics, mathematics, and biology). The inherently computational nature of chemical engineering shines through courses' active use of computational software such as Python, Matlab,Mathematica and COMSOL for modelling and data analysis. At the same time, classes and independent projects also focus on systematic analysis and problem solving, incorporating social, economic, environmental, and Graduation Requirements, All Options 280 of course, technical constraints to tackle the open-ended challenges of today and tomorrow with new and creative solutions. The option's curriculum begins in students' second year and continues through their third year with fundamental studies in heat transfer, fluid mechanics, mass transfer, thermodynamics, reactor design, and chemical kinetics. Upon building a common, foundational toolkit, chemical engineers then specialize in one of five different tracks: (biomolecular, sustainability, process, materials, or computational) to advance studies in specific realms of chemical engineering. The option also offers exposure to design elements through three distinct lab courses that entail hands-on, open-ended projects relevant to current research so students can innovatively apply chemical engineering concepts. In their fourth year, students can also pursue a senior thesis to explore research topics under the mentorship of a chemical engineering professor and gain experience in proposing a research plan, applying relevant lab techniques, and presenting results through an oral presentation and a written thesis. More information on the option requirements and individual tracks can be found on: https://tinyurl.com/2kxfnnva. The option's breadth enables its students to take on a wide variety of fields upon graduation, such as the manufacturing of both organic products (polymers, films, hydrocarbon fuels, and pharmaceuticals) and inorganic products (semiconductors and ceramics), as well as the development of sustainable technologies (energy efficiency, pollution management, climate mitigation, biofuels) and novel biotechnologies (enzyme engineering, cell culturing, food manufacturing), in industrial, consulting, and academic settings. First-year students normally take the core courses in mathematics, physics, chemistry, and biology (Ma 1 abc, Ph 1 abc, Chi ab, and Bi 1), as well as general chemistry laboratory (Ch3a [or Ch 3x]). Sophomores take ordinary differential equations (Ma 2), wave physics (Ph 2a), and organic chemistry laboratory (Ch/ChE 9). They also take the second-year organic chemistry course Ch 41 ab, and the basic chemical engineering courses (ChE 15, ChE 62, and ChE 63 ab). ChE 15 may be taken in the freshman or sophomore years. The third-year applied and computational mathematics course (ACM 95 ab) may be taken in the junior or sophomore years. Undergraduate research is emphasized, and students are encouraged, even in the first year, to participate in research with the faculty. In order to obtain a basic intellectual background, all students take courses in the fundamentals of chemical engineering through the junior year. During the junior and senior years, students diversify into one of five tracks (biomolecular, environmental, materials, process systems or computational), where they pursue concentrated study in their chosen area of chemical engineering. An optional senior thesis provides an opportunity to pursue independent research and design in lieu of one of the senior laboratories. Attention is called to the fact that any student whose gradepoint average is less than 1.9 at the end of an academic year in the subjects listed under the Division of Chemistry and Chemical Engineering may, at the discretion of the faculty in this division, be refused permission to Information for Undergraduate Students continue the work in this option.

CHEMISTRY OPTION AND MINOR (CH) The objective of the undergraduate option in chemistry is to produce graduates articulate in the fundamental concepts of the molecular sciences through a combination of coursework and laboratory experiences. The chemistry program at Caltech provides depth in the traditional areas of chemistry- organic and inorganic chemistry, chemical physics, theoretical chemistry, chemical biology, and biochemistry. Breadth in the program is found within the advanced coursework offerings and the specialized interests of the faculty, which may include topics such as: chemical synthesis and catalysis, chemical dynamics and reaction mechanisms, biochemistry, bioinorganic, bioorganic, and biophysical chemistry, nonlinear spectroscopy, electrochemistry, and materials chemistry. Graduation Requirements, All Options 284 Chemical research at Caltech is highly interdisciplinary, reflecting the increasing importance of molecular understanding to many fields of science. Major initiatives are fostering broad collaborations in molecular medicine, sustainability, environmental science, and nanomaterials. Caltech offers a Biochemistry Track within the chemistry option. Biochemistry is the study of the chemistry of biological macromolecules and how they enable diverse biological function. This track prepares students in this interdisciplinary area through a combination of coursework offered by Biology, Chemistry, and bioengineering as well as a senior research thesis in a chosen subject area in biochemistry. The Biochemistry Track provides for a wider range of coursework in Biology. Upon graduation, the diploma will read Chemistry (Biochemistry). The outcome of the undergraduate program in chemistry is to prepare students for advanced graduate study and ultimately careers in teaching and research at colleges and universities, in research for government and industry, in chemical technology from tech startups to corporations, and in leadership and policy positions. A two-term general chemistry course Ch 1 ab is taken by all first year students. The emphasis is on fundamental principles and their use in systematizing descriptive chemistry. Ch 1 ab must be passed to satisfy the Institute chemistry requirement. The student's qualifications for placing out of Ch 1 ab will only be determined by the performance on a placement examination to be administered in the summer prior to registration. The one-term required laboratory course (Ch 3 a or 3 x) presents basic principles and techniques of synthesis and analysis and develops the laboratory skills and precision that are fundamental to experimental chemistry. Students interested in Chemistry as a major are encouraged - though not required - to take Ch 3 a. Qualified students, with the consent of the instructor and the option representative, are allowed to substitute either Ch 4 a, Ch 8, or Ch/ChE 9 for the core requirement of Ch 3 a or Ch 3 x. Freshmen interested in the Biochemistry track are encouraged to take Bi 8 (as a substitute for the Bi 1 Core requirement) and Bi 9, if possible. First year students intending to major in chemistry are encouraged to take Ch 10 abc, a 3-unit introduction to research activities and opportunities in chemistry for undergraduates. Beyond the first year, each student in the chemistry option, in consultation with their adviser, selects a suitable course of study under the supervision of the division. The requirements of the option are listed below. A student wishing to deviate from these requirements should submit an alternate curriculum, with justifications, for consideration by their adviser and the Chemistry Curriculum and Undergraduate Studies Committee. The chemistry option representative should be consulted for the future scheduling of courses not offered during the current academic year. Undergraduates in the option must also take chemistry courses below the 100 level for a letter grade with the exception of the following courses, which are only offered on a pass/fail basis: Ch 1, Ch 3 a or Ch 3 x, Ch 90, and, if taken during the first or second terms as a Information for Undergraduate Students first-year student, Ch 4 ab, Ch 21 ab, and Ch 41 ab. Ch Senior Thesis Chemistry majors are strongly encouraged to undertake a Senior Thesis, though it is not a requirement. Students attempting a senior thesis in the chemistry option must complete the following requirements. 1. Three terms (27 units) of Ch 82 are to be completed during the junior and/or senior year of study; continued work from research experiences prior to the commencement of the senior thesis is encouraged. 2. By Add-Day of the first term of Ch 82, the candidate will submit a short (five-page) proposal delineating their project for approval by the research mentor and the Chemistry Curriculum and Undergraduate Studies Committee (CUSC). 3. The candidate will present a short progress report (maximum of five pages) at the end of each of the first two terms of Ch 82, describing the status of the research work and any results obtained. Upon evidence of satisfactory effort, the student will be allowed to continue their senior thesis. 4. A thesis of approximately 20 pages (excluding figures and references) will be presented to the mentor and the CUSC at the end of the third term of Ch 82. An oral thesis defense will be arranged by the CUSC. The thesis must be approved by both the research mentor and the CUSC. 5. Upon approval by the research mentor and the CUSC, the Ch 91 requirement for graduation may be satisfied by the written thesis and the progress reports from the first two quarters of Ch 82. A draft of the thesis is to be submitted by Week 7. Ch Double Majors For students simultaneously pursuing a degree in a second option, courses taken as required courses for that option can also be counted as chemistry electives (requirement 3, below) where appropriate. However, courses that count toward the electives requirement in the other option cannot simultaneously be counted toward satisfying the elective requirement in chemistry. Graduation Requirements The courses listed below would constitute a common core for many students in the option. Any student of the chemistry option whose grade-point average is less than 1.9 will be admitted to the option for the following year only with the special permission of the Division of Chemistry and Chemical Engineering. Passing grades must be earned in the courses that constitute the approved program of study, including those listed below. None of the courses satisfying option requirements may be taken pass/fail. Graduation Requirements, All Options 285 286 Ch Option Requirements (non-Biochemistry) 1. Ch 14, Ch 21abc, Ch 41abc, Ch 90, Ma 2, and Ph 2a. Ma 3 is recommended but not required. Students may make the following substitutions: For Ch14 (ESE/Ge 142); for Ch 21a (Ph 2b, Ph 12b, Ch 125a or Ph 125a); for Ch 21c (Ph 2c, Ph 12c, ChE/Ch 164 or Ph 127a). 100-level courses used in substitution for these option requirements may not also be counted towards the five terms of advanced electives. The Ch option requires Ch 90, Oral Presentation. Ch 91 is required to meet the Institute Core Requirement for Scientific Writing. For students in the biochemistry track, the senior thesis can be used to satisfy the writing requirement. 2. A minimum of five terms of laboratory work chosen from Ch 4ab, Ch 5ab, Ch 6, Ch 7, and Ch 15. One non-chemistry laboratory course may be used, chosen from MS 90, Ph 6 and Ph 7, or an alternative with sufficient Chemistry content, by approval of the Option Representative. One term of research, either 10 c (if taken during first or second year) or one term of Ch 82 (Senior Thesis), if taken for grades as the third and final term, may count for one of the five laboratory courses. 3. A minimum of five terms of advanced chemistry electives (which must total at least 45 units) from chemistry course offerings numbered 102 or higher, including cross-listed offerings but excluding Ch 180 and Ch 280. Students may petition to substitute up to but no more than one 100-level elective from another option, if the substituted course has substantial chemistry content. Ch 101 cannot be used to meet the five term requirement but can be used to meet the 45 unit requirement for advanced electives. The chemistry option strongly encourages students to engage in academic year research, and up to 27 units each of Ch 80 and Ch 82 can count toward the 486-unit requirement. Biochemistry Track Requirements 1.

To enroll in the program, the student should meet and discuss their plans with the option representative. In general, approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load. Courses that are used to satisfy the Chemistry minor requirements cannot be used to satisfy course requirements in another major. Graduation Requirements, All Options 290 COMPUTATION AND NEURAL SYSTEMS OPTION (CNS) Aims and Scope The undergraduate CNS option provides a foundation in math, physics, biology and computer science to prepare students for interdisciplinary graduate studies in neuroscience and career paths that involve computational applications inspired by properties of biological systems, such as artificial intelligence and computer vision. By graduation, students will have acquired knowledge in neurobiology, computation principles across different systems, methods used in modern neuroscience research, as well as the ability to critically evaluate and understand neuroscience literature, and be able to work in a team and communicate effectively. To accomplish these goals, students are expected to complete a series of math and physics courses to establish solid quantitative skills. Then, they are expected to take two groups of courses, of which one has a biology focus, while the other has a CS focus. Through these courses, students are exposed to different sub-disciplines of neuroscience while also acquiring the quantitative skills needed in graduate research and industry jobs. Students will receive instruction in scientific communications through SEC 10 and SEC 11, SEC 12, SEC 13, or Bi/BE 24. Undergraduate research is encouraged both during the academic year and through participation in summer research programs. Students with a grade-point average lower than 1.9 will not be allowed to continue in the option except with special permission from the option representative. CNS Option Requirements 1. Fulfillment of extended core requirements in Differential Equations (Ma 2 or equivalent); Probability and Statistics (Ma 3 or equivalent); Waves (Ph 2a, Ph 12a or equivalent), Thermodynamics and Statistical Mechanics (Ph 2c, Ph 12c or equivalent). 2.

The option introduces students to the mathematical and engineering foundations of the discipline. It provides considerable flexibility in course selection, together with a capstone project giving an opportunity for independent work in an area of the student's choice. Individual programs will be worked out in consultation with faculty advisers (the materials at cms.caltech.edu/academics/ugrad_cs may be helpful for this purpose. Any student in the computer science option whose grade-point average is less than 1.9 at the end of the academic year in the subjects listed in the option requirements may be refused permission to continue work in the option. CS Double Majors Students interested in simultaneously pursuing a degree in a second option must fulfill all the requirements of the computer science option. Specific courses that are explicitly required by both options only need to be taken once. For example, if both options require CS 38, then it can count for both. However, elective courses that satisfy the Information for Undergraduate Students "Advanced CS" requirement or the "Breadth" requirement cannot be double counted. That is, Requirements 4 and 8 must be fulfilled using courses that are not simultaneously used for fulfilling a requirement of the second option. To enroll in the program, the student should meet and discuss their plans with the option representative. In general, approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load. CS Option Requirements 1. CS fundamentals.

CS Minor The computer science minor is intended to supplement one of Caltech's undergraduate degrees and is designed for students who wish to broaden their knowledge beyond their normal major or who may wish to pursue a graduate program involving computer science. Students completing the computer science minor requirements will Graduation Requirements, All Options 296 have the phrase "minor in computer science" added to their transcripts. CS Minor Requirements 1. CS fundamentals. CS 1 or CS 1X; CS 2; CS 3. 2. Mathematical fundamentals. Ma 2; Ma 3; Ma/CS 6a or Ma 121a. 3. Intermediate CS. CS 21; CS 24; CS 38. 4. Advanced CS. 9 CS units numbered 114 or above that are not applied to the above requirements and are not simultaneously used for fulfilling a requirement of the student's major option. Pass/fail grading cannot be elected for courses taken to satisfy option requirements. Courses taken as part of the computer science minor are counted toward the total 486 units needed for Institute graduation requirements. To enroll in the program, the student should meet and discuss their plans with the option representative. In general, approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load. CONTROL AND DYNAMICAL SYSTEMS MINOR Control and dynamical systems (CDS) may be pursued as a minor concentration by undergraduates who are taking degrees in science, mathematics, or engineering. The CDS minor is intended to supplement one of Caltech's normal undergraduate degrees and is designed for students who wish to broaden their knowledge beyond their normal major or who may wish to pursue a graduate program involving control or dynamical systems. Students completing the minor requirements below in CDS will have the phrase "minor in control and dynamical systems" added to their transcripts and their graduating degree materials. CDS Minor Requirements • Complete CDS 110 or CDS 131 and CDS 231 or CDS 232 • Complete nine additional units in CDS courses, chosen from CDS 110, CDS 112, CDS 131, CDS 141, CDS 232, CDS 233, CDS 242, CDS 243, CDS 244. • Complete a three-term senior thesis approved by the CDS faculty. All CDS courses to be applied to fulfill the CDS minor requirements must be taken for grades, and students must obtain a grade of B or higher. The senior thesis requirement may be satisfied by completing a three-term senior thesis in the student's major option but on CDS subject matter, with the approval of the thesis topic by the CDS option representative, or by taking CDS 90 abc. Courses that are used to satisfy the CDS minor cannot be used to satisfy course requirements in the major options, with the exception that CDS 110 may be used in EAS options where this is part of their requirements (e.g., ChE, EE, ME) and the senior thesis requirement may be used to satisfy requirements for major options that require a senior thesis. Courses taken as part of the CDS minor are counted Information for Undergraduate Students toward the total 486 units needed for Institute graduation requirements. A typical course sequence would be to take either CDS 110 or CDS 232 in the junior year, followed by the remaining courses and the senior thesis in the senior year. Alternatively, it is possible to take all requirements in the senior year. In addition to the requirements above, CS 1 and CS 2 are highly recommended. ECONOMICS OPTION (EC) The economics option provides students with an understanding of the basic principles underlying the functioning of economic institutions. It offers a modern quantitative approach seldom available at the undergraduate level. The emphasis on economic principles and modern methodology provides students with an excellent preparation for graduate study in economics, as well as for professional work in the fields of business, law, economics, and government. The option is sufficiently flexible so that students can combine their pursuit of economics with studies in engineering, mathematics, or science. The core of the option consists of an economic theory component, a data analysis component, an applied microeconomic component, and a macroeconomic/growth component. Students are strongly encouraged to supplement this core with additional electives in economics, political science, and mathematics. Expected learning outcomes from completing the economics option include: • a proficiency in applying economic models to understand economic institutions; • a proficiency in analyzing field and experimental data to prove causal relationships between economic variables, to test economic theories, and to predict economic outcomes; • an understanding of the causes of regional and global long-term economic growth as well as the causes and consequences of economic crises throughout history; • an understanding of the role of market prices in allocating resources and affecting the distribution of wealth; • an appreciation of strategic behavior and asymmetric information in economic and social interactions; and an appreciation of the role of technological change and politics in shaping economic policies. Note: The official source on requirements for graduation is the Caltech catalog from the year in which a student began studies at Caltech. Please see the catalog online, from this and previous years, for information regarding the applicable option requirements. Graduation Requirements, All Options 297 298 Ec Option Requirements 1.

ELECTRICAL ENGINEERING OPTION (EE) The objective of the undergraduate program in Electrical Engineering at Caltech is to produce graduates who will attain careers and higher education that ultimately lead to leadership roles in academia, industry, and government in areas of rapidly advancing interdisciplinary technology related to telecommunications, solid-state, robotics, information, computer and electrical systems. The program prepares its students for either graduate study, entrepreneurial careers, or research and development work in government or industrial laboratories. It inspires them to undertake careers and professional practices that provide an opportunity to address the pressing technological needs of society. It accomplishes this by building on the core curriculum to provide a broad and rigorous exposure to the fundamentals (e.g., math, science, and principles of engineering) of electrical engineering. EE's other program objectives are multiple. The program strives to maintain a balance between classroom lectures and laboratory and design experience, and it emphasizes the problem formulation, system-design, and solving skills that are essential to any engineering discipline. The program is also intended to develop in each student self-reliance, creativity, teamwork ability, professional ethics, communication skills, and an appreciation of the importance of contemporary issues and lifelong intellectual growth. For interested students, there are opportunities to conduct research with a faculty member. Graduation Requirements, All Options 299 300 Students electing this option normally choose to take the introductory seminar EE 2 as a first-year elective. The formal study of electrical engineering begins in the sophomore year with courses such as, deterministic analysis of systems and circuits, EE 44; mathematics of electrical engineering, EE 55; introduction to dgital logic and embedded systems EE/CS 10ab; physics of electrical engineering, EE 40; the theory and laboratory practice of analog circuits, EE 45; and then a course on feedback control systems, EE 113 or CDS 110. The junior year features the fundamentals of signals and systems and digital signal processing, EE 111; random variables and stochastic processes, ACM/EE/IDS 116; electromagnetic engineering, EE 151; and analog electronics laboratory, EE 90. In the senior year, the student will be asked to demonstrate their ability to formulate and carry out a design or research project by taking the senior project design laboratory, EE 91, or senior thesis, EE 80 abc. In addition, the student throughout their studies and especially in the senior year, will have a significant opportunity to take elective courses that will allow them to explore earlier topics in depth, or to investigate topics that have not been covered previously. (See "suggested electives".) A student whose interests lie in the electrical sciences but who wishes to pursue a broader course of studies than that allowed by the requirements of the electrical engineering option may elect the engineering and applied science option. Attention is called to the fact that any student who has a grade-point average less than 1.9 at the end of the academic year in the subjects listed under electrical engineering may be refused permission to continue work in this option. EE Double Majors The electrical engineering option allows interested students to declare electrical engineering as one of the majors in a double major pursuit. To enroll in the program, the student should meet and discuss their plans with the option representative. In general, approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load. For students simultaneously pursuing a degree in a second option, courses taken as required courses for that option can also be counted as EE electives where appropriate. However, courses that count toward the electives requirement in the other option cannot be simultaneously counted toward satisfying the elective requirement in EE. To qualify for an EE degree, the student would need to complete all option requirements. EE Option Requirements 1. Ma 2, Ph 2 abc. Ph 12 abc can replace Ph 2 abc. 2. EE 2, SEC 10, one of SEC 11-13, EE/CS 10ab, EE 40, 44, 45, 55, 90, 111 and ACM/EE/IDS 116. 3. ACM 95ab. 4. EE 151 or EE/CS/IDS 160. 5. EE 91 or this requirement can be waived if a student completes EE 80 abc. Information for Undergraduate Students 6. In addition to the above courses, 72 units selected from any EE course numbered over 100. 7. Passing grades must be earned in a total of 486 units, including courses listed above. Courses used to satisfy requirements 1 through 6 must be taken for grades, unless they are only offered pass/fail.

ENGINEERING AND APPLIED SCIENCE OPTION (EAS) The engineering and applied science (EAS) option offers students the opportunity for study in a wide variety of challenging areas of science and technology by allowing each student to design a customized course of study that has breadth, depth, and rigor similar to the options listed above. The aim of the EAS option is to prepare students for research and professional practice in an era of rapidly advancing interdisciplinary technology. The program builds on the core curriculum to combine individual depth of experience and competence in a particular chosen engineering specialty, and a strong background in the basic and engineering sciences, with laboratory and design, culminating in a capstone design experience. It strives to develop professional independence, creativity, leadership, and the capacity for continuing professional and intellectual growth. The first year of the four-year course of study leading to a Bachelor of Science degree is common for all students of the Institute, although first-year elective subjects are available as an introduction to various aspects of engineering and applied science. At the end of the first year, students who elect the EAS option are assigned advisers as close to their expressed field of interest as possible, and together with their advisers they develop programs of study for the next three years. Beyond the Institute-wide requirements of physics, mathematics, and humanities, the EAS option requires one year of applied and computational mathematics and a prescribed number of units selected from a wide variety of engineering and applied science courses. Engineering design (synthesis), as distinct from analysis, is considered an essential part of every engineer's capability. Advisers will expect students to select a sufficient number of courses that place emphasis Graduation Requirements, All Options 305 306 on design. Any student in the EAS option whose grade-point average is less than 1.9 at the end of the academic year in the subjects listed in the option requirements may be refused permission to continue to work in the EAS option. EAS Option Requirements Students who have elected the EAS option must either choose one of the approved areas of concentration (see item 7 below), or by the end of the third term of the sophomore year submit a written proposed customized course of study and obtain approval for it from the EAS option representative. The course of study must include each of the following elements: 1. Fulfillment of core requirements in differential equations (Ma2 or equivalent); Probability and Statistics (Ma 3 or equivalent); Waves (Ph2a, Ph12a or equivalent), Quantum Mechanics (Ph 2b, Ph 12b, Ch 21a or equivalent); Thermodynamics and Statistical Mechanics (Ph 2c, Ph 12c, ChE 63, ME 11, Ch 21c or equivalent); 2. Demonstration of computer programming competency by taking CS 1, or by taking an approved alternative course, or by passing a placement exam administered by the computer science option by first term of sophomore year. a. 27 units of advanced EAS courses with the prefixes Ae, ACM, AM, APh, CE, CS, CDS, EE, ESE, MS, or ME; and b. 27 additional units of either advanced EAS courses or advanced science courses offered by the BBE, CCE, GPS, or PMA divisions. c. 9 units of laboratory courses taken from the following list: APh 77 bc, Ae/APh 104 bo, CE 180, CS/CNS 171,174, EE 45, 53, EE 90, EE 91, MS 90, MS 125, ME 72 ab, ME 50 ab, ME 90 bc; and d. 9 units of additional laboratory courses either from the list in За or from EAS courses with the word "laboratory" in the title, but excluding those courses for which first-year laboratory credit is allowed. 3. ACM 95 ab or Ma 108 abc or Ma 109 abc. None of these course sequences may be taken pass/fail. 4. SEC 10 or equivalent; one of SEC 11, SEC 12, or SEC 13 or equivalent. 5. Courses used to satisfy requirements 1-5 above must also satisfy a depth requirement, which must be met by a customized schedule of requirements that is rigorous, has both breadth and depth, and that includes a senior thesis or capstone design project, such as, but not restricted to, EE 80 abc, CS 80 abc, ME 90 abc, or two terms ofEE 91 ab. The student must submit a written proposal justifying their course selections, and obtain the approval of, the EAS option representative by the end of the third term of the sophomore year. 6. At least 117 units of EAS courses not including those used to satisfy requirements 4, 5, and 6 above. Information for Undergraduate Students 7. The customized schedule of requirements described in 7 shall include a major design experience. 8. Passing grades must be earned in at least 486 units, including those listed in requirements 1-8 above. ENGLISH OPTION AND MINOR (EN) The option in english provides students with a broad and intensive education in the rich traditions of literature in english from the middle ages to the present day, with a particular emphasis on british and american writing. The english faculty expects undergraduate option students to become familiar with a range of literary forms, genres, and styles of expression; to understand how authors and texts can be shaped by historical contexts; to appreciate differences in literary expression across time periods and national traditions; to develop critical reading skills through analysis and interpretation of literary texts; and to become effective writers in matters of style, organization, and interpretive argument. During the senior year, and typically in the first two terms, English option students enroll in En 99 ab (Senior Tutorial for English Majors) with a faculty member chosen by mutual agreement. The Senior Tutorial introduces students to advanced methods in literary research and analysis and provides an important means for assessing the progress of English option students in the rigorous study of literary texts and contexts. Students research, write, and revise a 25-30 page paper on a topic in British or American literature; En 99 a is primarily a research term, and En 99 b is primarily a writing term. Both terms involve regular tutorial consultation with the faculty instructor. English option students should begin considering a senior thesis topic in the third term of their junior year in consultation with the option representative or option adviser. In addition to the Senior Tutorial, the English option requires nine courses, which must include at least one course in each of the following areas: British literature, American literature, and literature before 1850. All English option students are assigned an adviser who will help select courses best suited to their needs and interests, including where appropriate a limited number of courses in related fields such as history, visual culture, and literature other than British and American. Students should consult their option adviser in advance of registration for each term. All courses counted toward the option must be taken for grades except for a first-year humanities course in English when taken in the first two quarters of a first-year student's first year. Most students pursue English as a second option. The emphasis on writing and on critical reading helps students develop communication skills that can enhance their careers as scientists, engineers, and medical professionals. The English option also provides excellent preparation for those seeking careers in law, business, and administration, and in any field that involves extensive communication. Graduation Requirements, All Options 307 308 En Option Requirements 1. En 99 ab. 2. 81 additional units of English courses numbered 99 and above. 27 of these units must include one course in British literature, one 190, and En/H 193, 197). Courses cannot be counted twice in meeting these distribution requirements. Up to nine units of first-year humanities in English (courses cross-listed Hum/En numbered 60 or below) and/or up to nine units of En 98 may be substituted for up to 18 of the remaining 54 English units. Students may also substitute courses in foreign literature (in the original or in translation) and/or, with authorization of the adviser, related humanities courses numbered above 99, for up to 18 of the remaining 54 English units. 3. 54 additional units of science, mathematics, and engineering courses. This requirement cannot be satisfied by courses listed as satisfying the introductory laboratory requirement or by a course with a number less than 10. Passing grades must be earned in a total of 486 units, including the courses listed above. Courses used to complete the English option under categories 1 and 2 above may not be used to satisfy the requirements of another option or minor. However, these courses may be used to satisfy core Institute requirements in the humanities. English Minor Requirements The English minor is designed for students who want to pursue concentrated study in English and/or American literature, without the extensive course work and the senior thesis required by the English option. English minors must take 72 units of English courses. These units may include one first-year humanities course; they may also include one directed reading course (En 98). Students wishing to do a minor in English must declare a minor with the English option representative. All courses to be counted toward the option in English must be taken for grades except for a first-year humanities course in English when taken in the first two quarters of a first-year student's first year. Students completing the English minor requirements will have the phrase "minor in English" added to their transcripts. 1. 72 units of English courses numbered 99 or above. 2. Nine units of first-year humanities in English (courses cross-listed Hum/En numbered 60 or below) may be substitute for any nine of the 72 units required for the minor. 3. Nine units of En 98 may be substituted for any nine of the 72 units required for the minor. Courses used to complete the English minor may not be used to satisfy the requirements of another option or minor. However, these Information for Undergraduate Students courses may be used to satisfy core Institute requirements in the humanities. ENVIRONMENTAL SCIENCE AND ENGINEERING OPTION AND MINOR (ESE) The ESE major is intended to train students in the environmental sciences, to pursue careers in academia, the public sector, or the private sector. The major can be pursued along two tracks: environmental physics and environmental chemistry. These tracks have separate course requirements and emphases, but at their hearts provide fundamental training in core scientific disciplines, with specialization in applications to the environmental and climate sciences. The two tracks share a sophomore year that continues the Core Curriculum's training in mathematics and physics. Each track requires a laboratory component and training in data analysis and statistics. All ESE majors must take three broad-based classes (ESE 101, 102, and 103) providing introductions to atmospheric and oceanic physics as well as marine and terrestrial biogeochemistry. The physics and chemistry tracks initially parallel their respective majors in the core disciplines. However, there are fewer required classes in the ESE major to enable students to design a curriculum that emphasizes the environmental sciences, after training in a core discipline. A total of 212 units are required for the major, leaving approximately nine classes of free choice outside the major and the core. Requirements for all ESE Majors, regardless of "Track" • Ma 2. • Ph 2a OR Ph12a. • Training in data analysis and statistics: BE/Bi 103ab OR Ph 20 and Ph 21 OR ChE 15 and BE/Bi 103b. • ESE 101, ESE 102, ESE 103. If students have taken ESE 1 then they can petition to not have either ESE 101 or ESE 103. • Science Writing Requirement: Ch 91 OR Ph 70. • Oral Presentation Requirement: Ge109 OR Ph 70 OR Ch 90. • ESE 91. Senior thesis (Optional) - Chemistry Track Requirements: Ch 21ab, Ch 41ab, ESE/Ge 142, ESE/Ch 176, ESE/Ge/Ch 171. • Laboratory Requirement: Ch/ChE 9 OR Ch 4a; AND Ch 15. • At least 77 units of electives, with a maximum of 2 additional lab classes. These courses are to be chosen by the student with approval by the Option Representative or their assigned surrogate. It is expected that the electives will span a range of options and constitute a coherent program in the Environmental Sciences. Graduation Requirements, All Options 309 310 Physics Track Requirements: Ph 12bc, Ph 106ab, ACM 95ab, ME 11c, ESE 130. • Laboratory Requirement: Ph 6.

It is designed for students who wish to broaden their studies beyond their major to include environmental science and engineering. Students completing the ESE minor requirements will have the phrase "minor in environmental science and engineering" added to their transcripts. ESE Minor Requirements 1. Complete 27 units of ESE 1, 101, 102, or 103 2. Complete 27 additional units of ESE courses (which may include up to 18 units of research under ESE 90, including the required written report). Except for research courses, all ESE courses to be applied to fulfill the minor requirements must be taken for grades, and students must maintain a minimum grade average of B- in this ESE coursework Courses that are used to satisfy the ESE minor requirements cannot be used to satisfy course requirements in the major. GEOLOGICAL AND PLANETARY SCIENCES (GPS) (GEOLOGY, GEOBIOLOGY, GEOCHEMISTRY, GEOPHYSICS, PLANETARY SCIENCE) AND MINOR The aim of the undergraduate program is to provide thorough training in the geological and planetary sciences and, wherever possible, to integrate these studies with courses in mathematics, physics, chemistry, and biology taken during the student's earlier years at the Institute. Active involvement in research, particularly during the summer, is encouraged. For geologists, field work is important because it provides first hand experience with geological phenomena that is challenging to completely explain or to fully understand solely from classroom or laboratory treatment. We offer a major in Geological and Planetary Sciences (GPS) that involves a number of core courses and various electives. We also provide information below on more focused tracks in each of the options, such that you can be awarded a major in GPS with a stated track on the transcript. These tracks are offered in geology, geobiology, geochemistry, geophysics, and planetary science. Electives permit students to follow lines of special Graduation Requirements, All Options 311 312 interest in related scientific and engineering fields. Those who do well in the basic sciences and at the same time have a compelling curiosity about the earth, climate, and the other planets are likely to find these options of interest, especially if they enjoy grappling with complex, interdisciplinary problems. Many students majoring in the earth and planetary sciences pursue further training at the graduate level, while others take jobs that leverage a strong background in earth science including opportunities in sustainability, risk assessment, and climate policy. For those students with an interest in geobiology, there are options to either be associated with the Biology and Biological Engineering or the GPS division. This association formally affects some of the course requirements that are needed to satisfy the undergraduate degree. Additionally, a students' affiliation with one division or another is likely to significantly shape their choice of elective courses and potentially research opportunities. We suggest that any interested students discuss this choice with their adviser and/or contact the option representative in the GPS geobiology option. It is strongly recommended that students start the GPS major with the Ge 11 sequence in the sophomore year. Because Ge 120 ab may not be offered every year, students in the geology track may also need to take Ge 106 and Ge 120 a in winter and spring term of their sophomore year in order to prepare for Ge 120 b the following summer. Suggestions of elective courses that fulfill degree requirements are listed below, and include some 200-level courses. While these courses are primarily intended for graduate students, advanced undergraduates may enroll with permission of the instructor. GPS Double Majors For students simultaneously pursuing a degree in a second option, courses taken as required courses for that option can also be counted as Ge electives where appropriate. However, courses that count toward the electives requirement in the other option cannot simultaneously be counted toward satisfying the elective requirement in GPS. GPS Undergraduate Degree Requirements The following core courses are required for all GPS option tracks: 1. Ge 1 or Ge 11a 2. Ge 11a, 11b, 11c, 11d 3. A writing class, (at least three units) 4. An oral presentation class (at least three units) 5. Ma 2 6. Ma 3 or Ge/Ay 117 7. Ph 2a or Ph 12a 8. One of: Ph 2b, Ph 12b, Ph 2c, Ph 12c Courses that cover both writing and presentation, e.g. En/Wr 84, that are at least 6 units may be counted towards requirements (3) and Information for Undergraduate Students (4) above. Students that elect to use Ge 11a for requirement (1) may substitute an elective for Ge 11a in requirement (2). Assuming 3 units each for requirements (3) and (4), the total core requirements totals 87 units; a writing course such as En/Wr 84 (9 units) would increase this to 90 units. The GPS Major (no special track) In addition to the core requirements stated above, the student may design a course of study, in consultation with their adviser, that satisfies the following requirements: 63 units of advanced Science, Mathematics, or Engineering outside GPS. 72 units of GPS elective coursework. The combination of the core requirements and the 135 units of GPS major requirements should total no less than 222 units. Geology Track In addition to the core requirements stated above, a GPS major with a Geology track must include: 1. Either ACM 95ab or a full-year chemistry sequence, Ch 41abc or Ch 21abc 2. Ge 106 3. Ge 114 4. Ge 115 ab 5. Ge 120 ab 6. Ge 112 or Ge 125 7. Additional elective courses in Ge or ESE to bring the total number of units to 220, including the core classes.

The requirements for the minor are as follows: 1. Ge 11a 2. Select two of the following courses: Ge 11b, Ge 11c, Ge 11d 3. 27 units of 100-level or higher GPS courses, excluding Ge 109 Information for Undergraduate Students If the courses selected for requirement (3) above are sufficiently focused in one of the GPS options, students may opt to include a track on their transcript (e.g. Minor in GPS with [option] track). Minor tracks are possible in Geobiology, Geochemistry, Geology, Geophysics, and Planetary Sciences. The courses selected for (3) must be approved by the appropriate option representative in the division. Any 27 units that satisfy (3) may be used to satisfy the GPS minor, regardless of focus. HISTORY OPTION AND MINOR (H) Students who choose the history option will learn how to do history-how to think critically about past societies and their development, how to read evidence closely, and how to express arguments in writing. With the guidance of a faculty adviser in history, students taking the option will explore the range of human experience in the realms of politics, culture, religion, and economics, as well as science and technology. They will learn both to challenge and revise existing historical narratives and question their own ideas and assumptions about the past. Students will develop the writing skills that will enable them to use historical sources to make effective arguments, and they will receive extensive feedback on their writing from their adviser and from other faculty members. The history option thus provides science and engineering students with an important supplement to the scientific training and technical skills they acquire in other courses and options. It will help them to understand the world of human beings and human behavior outside of science with which they will interact and which their scientific work will affect; to set themselves and their work as scientists and engineers in this wider context; and to communicate what they are doing to a wider public as well as to their colleagues. In addition, it offers excellent preparation for careers in business, administration, law, journalism, or public affairs, as well as a solid foundation for graduate work in history. History majors must take at least 99 units of history courses (which may include a first-year humanities course in history) during their four years as undergraduates. Of these, 27 must be in the senior tutorial (H 99 abc). All courses to be counted toward the history option must be taken for grades except for a first-year humanities course in history when taken in the first two quarters of a first-year student's first year. History majors may also choose to take one term of H 98, an individual program of directed reading that will allow students to explore areas of history not covered by regular courses. Each history major will choose an area of concentration in consultation with their adviser and the history option representative. These areas might include, but are not restricted to, fields such as ancient history, medieval Europe, early-modern Europe, modern Europe, Russian history, American history pre- 1865, American history post-1865, early-modern history of science, modern history of science, or economic history. A student must take 63 units of courses in this area; 27 of these units must be in the senior tutorial H 99 abc. Graduation Requirements, All Options 321 322 In the senior tutorial, students will have the opportunity over the course of three terms to explore in depth an historical subject of particular interest to them, while working one-on-one with a member of the history faculty. They will learn how to carry out historical research, in libraries as well as on-line, and engage critically with both primary and secondary historical sources. Finally, they will learn, under the direct supervision of their faculty mentor, to organize and to write an extensive research paper, of at least 30 pages, that makes an original, clear and persuasive scholarly argument. In H 99a, students will carry out general research in their area of interest, and identify the specific topic on which they wish to write. In H 99b they will learn to frame a research question, carry out independently the necessary research to answer it, and generate an outline of their paper. In H 99c they will write and revise their paper in response to feedback from their faculty mentor. Each student must take the remaining 36 units of history required by the option in areas other than the area of concentration, again defined in consultation with their adviser and the history option representative. These areas may include not only fields within the discipline of history proper, but also useful cognate fields such as economics, political science, anthropology, law, English, or a foreign language. A student considering the history option when they come to Caltech will be well advised to take a first-year humanities course in history (courses cross-listed Hum/H numbered 60 or below). In the sophomore year, the student should take upper-level history courses, but this is also a good time to pursue the study of English or philosophy, to begin or continue a foreign language, and to do introductory work in the social sciences. A student will normally make a commitment to an area of concentration early in the junior year. At the beginning of the senior year, a history major will enroll in H 99 abc with a faculty member in their area of concentration. H Option Requirements 1. H 99 abc. 2. 72 additional units of history courses numbered 99 or above. Up to nine units of first-year humanities in history (courses cross-listed Hum/H numbered 60 or below) and/or up to nine units of H 98 may be substituted for up to 18 of these units. 3. 63 of the total history units, including H 99 abc, must be in an area of concentration, as defined in consultation with the student's adviser and the history option representative. 4. 36 of the total history units must be in an area or areas other than the area of concentration, as defined in consultation with the student's adviser and the history option representative. H 99 abc may not be used to fulfill this requirement. 5. 54 additional units of science, mathematics, and engineering courses. This requirement cannot be satisfied by courses listed as satisfying the introductory laboratory requirement or by menu courses. Information for Undergraduate Students 6. Three units of oral communication. En/Wr 84 satisfies this requirement, as do oral communication courses offered by other options. 7. Passing grades must be earned in a total of 486 units, including the courses listed above. Courses used to complete the history option under categories 1, 2, or 3 above may not be used to satisfy the requirements of another option or minor. H Minor Requirements The history minor is designed for students who want to pursue concentrated study in history without the extensive course work and the senior thesis required by the history option. History minors must take 72 units of history courses. These units may include one first-year humanities course; they may also include one directed reading course (H 98). All courses to be counted toward the history minor must be taken for grades except for a first-year humanities course in history when taken in the first two quarters of a first-year student's first year. Students wishing to do a minor in history must declare a minor with the history option representative. Students completing the history minor requirements will have the phrase "minor in history" added to their transcripts. 1. 72 units of history courses numbered 99 or above. 2. Nine units of first-year humanities in history (courses cross listed Hum/H numbered 60 or below) may be substituted for 3. any nine of the 72 units required for the minor. 4. Nine units of H 98 may be substituted for any nine of the 72 5. units required for the minor. Students cannot use history minor requirements to satisfy a different option or minor. HISTORY AND PHILOSOPHY OF SCIENCE OPTION AND MINOR (HPS) The history and philosophy of science option (HPS) provides students the opportunity to explore the historical evolution of the sciences and the philosophical perspectives that inform them, as well as the dynamics between science, technology, and other human endeavors. HPS courses in history help students learn about the origins of experimental practice; the social and institutional contexts of science; the origins and applications of quantitative methods; specific developments since antiquity in physics, biology, chemistry, geography and cartography, medicine; and biographical and comparative studies in these fields. HPS courses in philosophy deal with issues in causation and explanation; the foundations of probability and statistical inference; and philosophical problems in particular fields such as biology, mathematics, medicine, neuroscience, and physics. In their coursework, students receive regular feedback from the faculty on their research, writing, and Graduation Requirements, All Options 323 324 presentation skills. They have the opportunity to carry out independent research, especially in their thesis work, and present their findings in a seminar setting. This option thus aims to give students a broad, basic understanding of how science is practiced and how that practice has changed over time. Students learn to address questions such as: To what extent was the scientific revolution revolutionary? What is a scientific explanation and how do scientists go about constructing and justifying one? How have conceptions of scientific experimentation changed? What are the ethical issues raised by experimentation with human or animal subjects? How has relativity theory changed our conceptions of space and time? The option is designed to complement the regular science curriculum at Caltech, offering students the opportunity to enlarge upon, and to contextualize, the strong technical skills they acquire in other courses and options. Because of its emphasis on essay writing and formulating complex philosophical and historical arguments, our curriculum provides training in writing and communication skills that are increasingly vital today. The HPS option provides excellent preparation for students going into law, business, medicine, science journalism and public affairs, and it also prepares students for graduate work in the history and/or philosophy of science. HPS Option Requirements 1. Hum/H/HPS 18; HPS 102 ab; HPS/PI 120; and HPS 103 (one quarter). (HPS 102 b fulfills the Institute science writing requirement.) 2. One advanced course in the history of science, chosen from HPS/H offerings with a course number of 98 or higher; one advanced course in philosophy of science, chosen from HPS/PI offerings with a course number of 98 or higher; and any four courses in HPS. (No more than 9 units of HPS 98 may be counted towards the HPS major.) 3. 45 units of courses in science, mathematics, and engineering. This requirement cannot be satisfied by courses listed as satisfying the introductory laboratory requirement or by a course with a number less than 10. 4. Passing grades must be earned in a total of 486 units, including all courses used to satisfy the above requirements. Courses used to complete the history and philosophy of science option under categories 1, 2, or 3 above may not be used to satisfy the requirements of another option or minor. We recommend that students intending to follow the HPS option take Hum/H/HPS 18, Introduction to History of Science, as one of their first-year humanities courses. Students making the decision to follow this option in their sophomore year should take Hum/H/HPS 18 and HPS/PI 120, Introduction to Philosophy of Science, as early as possible in that year. Students may also enter the option in their junior year if they can complete the option's requirements in time for graduation. Please also note the following: Information for Undergraduate Students Not all required courses are offered each term; students should consult the current catalog to determine which terms required courses are being offered, and should construct their course plan for the year accordingly. We encourage students to choose their advanced social science electives from among courses that will enlarge their perspective on topics related to HPS (for example, Ec 118, Ec/SS 128, Ec 129, Ec 130, PSY 101, PSY 115, PSY 125, PSY 130, PS 120, PS 121, PS 122, An 22). HPS 102ab, the Senior Research Seminar, may be taken in any two consecutive terms in the Senior year. Students should coordinate with their HPS adviser in determining their course schedule. HPS Typical Course Schedule First Year It is recommended that students intending to follow the HPS option take Hum/H/HPS 18 as one of their first-year humanities courses.

Students should coordinate with their HPS adviser in determining their course schedule. HPS Minor Requirements The minor in HPS is designed for students who want to pursue concentrated study in the field without the extensive course work and the senior thesis required by the HPS option. HPS minors must complete 72 units of HPS courses. First-year Humanities courses other than Hum/H/HPS 18 may not be counted towards an HPS minor. Students wishing to do a minor in HPS must declare a minor with the HPS option representative. Those completing the HPS minor requirements will have the phrase "minor in History and Information for Undergraduate Students Philosophy of Science" added to their transcripts. 1. 72 units of HPS courses numbered 99 or above. 2. 9 units of HPS 98 may be substituted for any 9 of the 72 unit required for the minor. 3. 9 units of Hum/H/HPS 18 may be substituted for any 9 of the 72 units required for the minor. Students cannot use HPS minor requirements to satisfy a different option or minor. INFORMATION AND DATA SCIENCES (IDS) The information and data sciences are concerned with the acquisition, storage, communication, processing, and analysis of data. These intellectual activities have a long history, and Caltech has traditionally occupied a position of strength with faculty spread out across appliec mathematics, electrical engineering, computer science, mathematics, physics, astronomy, economics, and many others disciplines. In the last decade, there has been a rapid increase in the rate at which data are acquired with the objective of extracting actionable knowledge — in the form of scientific models and predictions, business decisions, and public policies. From a technological perspective, this rapid increase in the availability of data creates numerous challenges in acquisition, storage, and subsequent analysis. More fundamentally, humans cannot deal with such a volume of data directly, and it is increasingly essential that we automate the pipeline of information processing and analysis. All areas of human endeavor are affected: science, medicine, engineering, manufacturing, logistics, the media, entertainment. The range of scenarios that concern a scientist in this domain are very broad — from situations in which the available data are nearly infinite (big data), to those in which the data are sparse and precious; from situations in which computation is, for all practical purposes, an infinite resource to those in which it is critical to respond rapidly and computation must thus be treated as a precious resource; from situations in which the data are all available at once to those in which they are presented as a stream. As such, the information and data sciences now draw not just upon traditional areas spanning computer science, applied mathematics, and electrical engineering - signal processing, information and communication theory, control and decision theory, probability and statistics, algorithms— but also a range of new contemporary topics such as machine learning, network science, distributed systems, and neuroscience. The result is an area that is new, fundamentally different that related areas like computer science and statistics, and that is crucial to modern applications in the physical sciences, social sciences, and engineering. The Information and Data Sciences (IDS) option is unabashedly mathematical, focusing on the foundations of the information and data sciences, across its roots in probability, statistics, linear algebra, and signal processing. These fields all contribute crucial components of data science today. Further, it takes advantage of the interdisciplinary Graduation Requirements, All Options 327 328 nature of Caltech by including a required set of application courses where students will learn about how data touches science and engineering broadly. The flexibility provided by this sequence allows students to see data science in action in biology, economics, chemistry, and beyond. In addition to a major, the IDS option offers a minor that focuses on the mathematical foundations of the information and data sciences but recognizes the fact that many students in other majors across campus have a need to supplement their options with practical training in data science. IDS Option Requirements 1. Computer Science Fundamentals. CS 1 or CS 1X; CS 2; CS 21 or Ma/CS 6c; and CS 38. 2. Mathematical Fundamentals.

Passing grades must be earned in total of 486 units, including all courses used to satisfy the above requirements. IDS Double Majors Students interested in simultaneously pursuing a degree in a second option must fulfill all the requirements of the Information and Data Sciences option. Courses may be used to simultaneously fulfill requirements in both options. However, it is required that students have at least 54 units of "Advanced Electives" and 18 units of "Applications of Data Science" that are not simultaneously used for fulfilling a requirement of the second option, i.e., the requirements of the Advanced Electives and the Applications of Data Science sections must be fulfilled using courses that are not simultaneously used for fulfilling a requirement of the second option. Any proposal to replace these courses must be discussed with the option administrator. To enroll in the program, the student should meet and discuss their plans with the option representative. In general, approval is contingent on good academic performance by the student and demonstrated ability for handling the heavier course load.

Courses used to fulfill this requirement may not also be used to fill the any requirement above. Courses used to fulfill requirements in the "Applications of Data Science" and "Advanced Electives" requirements cannot be used to fulfill (i) a requirement for another major or minor; or (ii) the institute humanities and social sciences requirements. Any replacement of these courses must be discussed with the option administrator. Pass/fail grading cannot be elected for courses taken to satisfy option requirements. Courses taken as part of the data science minor are counted toward the total 486 units needed for Institute graduation requirements. Typical course schedule A typical course sequence is to take CS 1 during the first year; Ma/CS 6a, Ma 3, CS2 and CS38 during sophomore year; ACM/EE/IDS 116, ACM/IDS 104, CMS/CS/CNS/EE/IDS 155, and IDS/ACM/CS 157 during junior year; and EE/IDS 111 and the elective courses during senior vear. Graduation Requirements, All Options 331 332 INTERDISCIPLINARY STUDIES PROGRAM (ISP) The Interdisciplinary Studies Program (ISP) is an undergraduate option that allows the student to create their own scholastic requirements, under faculty supervision, and to pursue positive educational goals that cannot be achieved in any of the other available options. A student's program may include regular Caltech courses, research courses, courses at other schools, and interdisciplinary study courses (item 5, next page). In scope and depth, the program must be comparable to a normal undergraduate program, but it need not include all of the specific courses or groups of courses listed in the formulated Institute option requirements for undergraduates. The Curriculum Committee, a standing committee of the faculty, has overall responsibility for the program. In addition, each student has their own committee of at least two advisers, two of whom must be professorial faculty. Application material may be obtained at the dean of undergraduate students' office or website. ISP Administrative Procedures and Guidelines 1. An interested student must recruit at least two professorial faculty members representing at least two different degree-granting options to serve as the ISP faculty committee. Each member of the faculty committee must provide a letter that includes: a. Faculty name and department/division, and the discipline they "represent" within the proposed ISP. b. Faculty's assessment of the student's ISP proposal, including the proposed degree title, as it relates to that faculty's discipline. c. Faculty assessment of whether the student could choose an existing degree-granting option with some acceptable accommodations, rather than create an ISP. That is, does this ISP enable something that could not be accomplished in a single option or major/minor combination. 2. Send the ISP proposal (cover sheet, proposed curriculum, and the aforementioned letters from professorial faculty advisers to the dean of undergraduate students for review and approval. 3. The dean of undergraduate students sends the ISP petition to the Curriculum Committee for review and final approval. This contract includes the agreed-upon content of the student's program and the methods for ascertaining satisfactory progress for those parts of the student's program that are not standard Institute courses. This contract may of course be amended, but any amendments must be approved by the committee of two and the Curriculum Committee. Copies of each student's contract and of all amendments thereto, along with all ISP records for each student and their transcript, are kept in the permanent files of the Registrar's Office. Passing grades must be earned in a total of 486 units. 4. The progress of each student in the ISP is monitored each quarter by the registrar, and any deviations from the terms of the contract are reported to the chair of the Curriculum Committee. Standards for acceptable progress and for satisfactory Information for Undergraduate Students completion of the terms of the contract are the responsibility of the Curriculum Committee. When the Committee is satisfied that the terms of the contract have been fulfilled by the student, it recommends the student to the faculty for graduation. 5. A plan of study may include special ISP courses to accommodate individual programs of study or special research that falls outside ordinary course offerings. In order that credit be received for an ISP course, a written course contract specifying the work to be accomplished, time schedule for progress reports and completed work, units of credit, and form of grading must be agreed upon by the instructor, the student, and the committee of two, and submitted to the registrar prior to initiating the work in the course. ISP courses are recorded on the student's transcript in the same manner as are other Caltech courses. 6. ISPs are intended for multiyear programs. Accordingly, the Curriculum Committee urges students contemplating an ISP to submit their petition during their second year and will not normally consider such petitions any later than the first term of the student's third year. MATERIALS SCIENCE OPTION (MS) The aim of the Materials Science option is to prepare students for research, professional practice, or advanced study in a rapidly advancing interdisciplinary field, focusing on the relationships between the properties of materials and their internal structure and how this structure can be controlled. The program builds on the core curriculum to develop analytical competence and use it for individualized research, culminating in a one-year senior thesis. Materials Science students develop professional independence, creativity, leadership, and the skills for continuing professional and intellectual growth. The first year of the four-year course of study leading to a Bachelor of Science degree is common for all students of the Institute, although first-year elective subjects are available as an introduction to various aspects of engineering and applied science. At the end of the first year, students who elect the Materials Science option are assigned advisers appropriate for their expressed field of interest. Together with their advisers, they develop programs of study for the next three years. Beyond the Institute-wide requirements of physics, mathematics, and humanities, the Materials Science option requires one year of applied and computational mathematics and a prescribed number of units selected from a wide variety of courses in science and engineering. An undergraduate thesis is an essential part of the academic program. Any student in the Materials Science option whose grade-point average is less than 1.9 at the end of the academic year in the subjects listed in the option requirements may be refused permission to continue to work in the Materials Science option. Graduation Requirements, All Options 333 334 MS Option Requirements 1.

Math students go well beyond the basics to study the structures of algebra, analysis and geometry, as well as the rudiments of combinatorics and set theory. Students learn to write coherent and complete proofs of various assertions, to work out non-trivial examples and to use computational tools. The schedule of courses in the undergraduate mathematics option is flexible. It enables students to adapt their programs to their needs and mathematical interests and gives them the opportunity to become familiar with creative mathematics early in their careers. Some students go to use their background in mathematics as an entry to other fields, such as physics, computer science, statistics, economics, business, finance, medicine and law. First-year students considering majoring in mathematics should be aware that the department strongly recommends taking the analytical track of Ma 1 bc. Any student whose grade-point average is less than 1.9 at the end of the academic year, in the subjects under mathematics and applied and computational mathematics may be refused permission to continue work in the mathematics options.

Information for Undergraduate Students MECHANICAL ENGINEERING OPTION (ME) The objective of the undergraduate program in Mechanical Engineering at Caltech is to produce graduates who will attain careers and higher education that ultimately lead to leadership roles in academia, industry, and government in areas of rapidly advancing interdisciplinary technology related to fluid, solid, thermal, and mechanical systems. The program prepares students for graduate school and professional practice and inspires them to undertake careers that provide an opportunity to address the pressing technological needs of society. Specifically, the program builds on Caltech's core curriculum to combine individual depth of experience and competence in a particular chosen mechanical engineering specialty with a strong background in the basic and engineering sciences. It maintains a balance between classroom lectures and laboratory and design experience, and emphasizes the problem-formulation and solving skills that are essential to any engineering discipline. The program also strives to develop in each student self-reliance, creativity, leadership, professional ethics, and the capacity for continuing professional and intellectual growth. For interested students, there are opportunities to conduct research with a faculty member. The outcome of the undergraduate program is to prepare the student to build on a fundamental education in physics, mathematics, chemistry, and biology and to apply those principles to the solution of open-ended engineering problems; to design, analyze, measure, and evaluate fluid, thermal, and mechanical systems; to work effectively as part of a team; to communicate effectively; to apply ethical considerations; and to understand the broader impacts of engineering developments, including societal, cultural and environmental concerns. Mechanical engineering is the branch of engineering that is generally concerned with understanding forces and motion, and their application to solving problems of interest to society. The field includes aspects of thermodynamics, fluid and solid mechanics, mechanisms, materials, and energy conversion and transfer, and involves the application of physics, mathematics, chemistry, and increasingly, biology and computer science. Importantly, the field also emphasizes the process of formulation, design, optimization, manufacture, and control of new systems and devices. Technical developments in the last decade have established the importance of interdisciplinary engineering and science, and as a result, new technical disciplines within mechanical engineering have emerged. These new areas build on an understanding of the fundamental behavior of physical systems; however, the focus of this work is at the interfaces between traditional disciplines. Examples of the new disciplines include micro- and nano-mechanical systems, simulation and synthesis, integrated complex distributed systems, and biological engineering. Mechanical engineers can be found in many fields, including automotive, aerospace, materials processing and development, power Graduation Requirements, All Options 339 340 production, consumer products, robotics and automation, semiconductor processing, and instrumentation. Mechanical engineering can also be the starting point for careers in bioengineering, environmental and aeronautical engineering, finance, and business management. The Mechanical Engineering Option is accredited by the Engineering Accreditation Commission of ABET, 111 Market Place, Suite 1050, Baltimore, MD 21202-4012, (410) 347-7700. At the end of the first year, students who elect the Mechanical Engineering Option are assigned advisers as close to their expressed field of interest as possible, and together they develop programs of study for the next three years. the requirements below, may elect the Engineering and Applied Science Option. Attention is called to the fact that any student whose grade-point average is less than 1.9 at the end of the academic year in the required courses listed below may be refused permission to continue work in this option.

PHILOSOPHY OPTION AND MINOR (PI) The philosophy option provides students with a broad education in philosophy that is designed to complement the scientific curriculum at Caltech. Philosophy majors will be expected to learn about some of the major figures and movements in the history of philosophy, and to learn about contemporary philosophical debates. The philosophy option also aims to provide students with new perspectives on the material they learn in their science courses, and to enable them to bring their technical skills and scientific learning to traditional problems in philosophy. The philosophy curriculum will help students to acquire the basic tools of philosophical analysis: the ability to read and interpret philosophical texts; the ability to identify strengths and weaknesses of philosophical arguments; the ability to develop well-reasoned defenses of philosophical positions; and the ability to anticipate objections to one's own views. In addition, the philosophy option will train students to express themselves clearly and concisely in both writing and speaking. These critical thinking and communication skills provide an excellent foundation for any intellectual endeavor, and are critical to those pursuing careers in fields such as law, business, medicine, and scientific research. The courses in the philosophy option concentrate in four major areas: philosophy of science; philosophy of mind, brain, and behavior; history of philosophy; and ethics. In their coursework, students will have the opportunity to discuss and debate philosophical issues in small groups, and will learn how to offer and receive constructive criticism. They will also receive detailed feedback on their persuasive writing from several different members of the philosophy faculty. In their senior thesis, philosophy majors will have the opportunity to pursue more intensive research in one particular area of philosophy, and to sustain an argument on a larger scale, while working one-on-one with a member of the philosophy faculty. This will provide interested students with a solid foundation for graduate work in Information for Undergraduate Students philosophy and related fields. Philosophy majors must take at least 99 units of philosophy courses during their four years as undergraduates. These must include 18 units of PI 90 ab, to be taken in any two consecutive terms in the senior year. The 99 units may include nine units of first-year humanities in philosophy (courses cross-listed Hum/Pl numbered 60 or below), nine units of Pl 98, and up to 18 units of study in related disciplines. Depending on their interests, philosophy majors may be required by the option representative or their advisers to take up to 18 units in one or more related areas. For example, students writing on political philosophy or philosophy of neuroscience will be expected to have the appropriate political science or neuroscience background. Students whose primary interest lies in the philosophy of science— particularly in the philosophy of specific sciences such as physics or biology — will have their intellectual interests best served by taking classes in both the history and philosophy of science. Such students are encouraged to pursue the HPS option; or, if they choose the philosophy option, they may be required to take some history of science courses as part of their 99-unit requirement. Students considering the philosophy option will be well advised to take a first-year humanities course in philosophy. From the sophomore year onward, they should plan on taking one philosophy course per term, culminating in two terms of Pl 90 ab in the senior year. Students in Pl 90 ab work with a faculty adviser to write a 10,000-to 12,000-word paper on a topic of mutual interest. Senior theses are expected to be of a high standard and to form the basis of students' applications to graduate study in philosophy, should they so desire. With the exception of Pl 98 and courses taken during the first two quarters of the first-year student's first year, all courses to be counted toward the philosophy option must be taken for grades unless special permission is granted by the option representative. Pl Option Requirements 1. PI 90 ab. 2. 63 units of advanced philosophy courses, numbered 99 or above. Up to nine units of first-year humanities in philosophy (courses cross-listed Hum/PI numbered 60 or below) and/or up to nine units of Pl 98 may be substituted for up to 18 of these advanced units. 3. 18 units of advanced philosophy courses numbered 99 or above, or advanced non-philosophy courses that are closely related to the student's area(s) of philosophical interest. (Students wishing to count non-philosophy courses toward their option requirements must obtain prior approval from the philosophy option representative or their adviser. Students will normally not be permitted to satisfy this requirement with core courses.) 4. 54 units of science, mathematics, and engineering courses in addition to the core. This requirement cannot be satisfied by core or menu courses, or by courses listed as satisfying the introductory laboratory requirement. Students are strongly Graduation Requirements, All Options 343 344 encouraged to choose their additional courses in areas that complement their philosophy studies. 5. Three units of oral communication. En 84 satisfies this requirement, as do oral communication courses offered by other options. 6. Passing grades must be earned in a total of 486 units, including the courses listed above. Courses used to complete the philosophy option under categories 1, 2, or 3 above may not be used to satisfy the requirements of another option or minor. Pl Minor Requirements The minor in philosophy is designed for students who want to pursue concentrated study in philosophy without the extensive course work and the senior thesis required by the philosophy option. Philosophy minors must complete 72 units of philosophy courses. Students wishing to do a minor in philosophy must declare a minor with the philosophy option representative. Students completing the philosophy minor requirements will have the phrase "minor in philosophy" added to their transcripts. With the exception of Pl 98 and courses taken during the first two semesters of a first-year student's first year, all courses to be counted toward the philosophy option or minor must be taken for grades unless special permission is granted by the option representative. 1. 72 units of philosophy courses numbered 99 or above. 2. Nine units of Pl 98 may be substituted for any nine units of the 72 required for the minor. 3. Nine units of first-year humanities in philosophy (courses cross-listed Hum/PI numbered 60 or below) may be substituted for any nine units of the 72 required for the minor. Courses used to complete the philosophy minor may not be used to satisfy the requirements of another option or minor. PHYSICS OPTION (PH) The physics option offers instruction in the fundamentals of modern physics and provides a foundation for graduate study, which is generally necessary for a career in basic research. The physics program also forms an excellent basis for future work in a variety of applied fields. An intensive version of the sophomore physics course (waves, quantum mechanics, and statistical mechanics) is offered for those planning further study in physics and the required junior-level courses give a thorough treatment of fundamental principles. Elective courses taken during the junior and senior years allow students to explore their particular interest. Some electives offer broad surveys, while others concentrate on particular fields of current research. A choice of laboratory course is offered at several levels. Students interested in concentrating their studies in one specific area of physics should refer Information for Undergraduate Students to the undergraduate physics website for course schedule recommendations. Students are encouraged to become active participants in research on campus, both during the summer and during the school year. Academic credit for physics work done outside of the classroom can be awarded in a variety of ways. Students must maintain a grade-point average of 1.9 or better each year in the subjects listed under this division to remain in the physics option.

Information for Undergraduate Students 351 Graduation Requirements, All Options Section Four Information for Graduate Students 352 Information for Graduate Students The Institute offers graduate degrees of Master of Science and Doctor of Philosophy, and in special cases the degree of Engineer. The Institute is organized into six academic divisions: Biology and Biological Engineering; Chemistry and Chemical Engineering; Engineering and Applied Science; Geological and Planetary Sciences; the Humanities and Social Sciences; and Physics, Mathematics and Astronomy. Graduate work at the Institute is further organized into graduate options, which are supervised by those professors whose interests and research are closely related to the area of the option, within the administrative jurisdiction of one or more of the divisions. A faculty member serves as the representative for an option. The option representative provides consultation on academic programs, degree requirements, financial aid, etc., and provides general supervision to graduate students in the option. The Committee on Graduate Studies, which includes the option representatives, elected members of the faculty at large, and graduate students appointed by the Graduate Student Council, exercises supervision over the scholastic requirements established by the faculty for all advanced degrees, provides policy guidance to the dean of graduate studies, and certifies all candidates for graduate degrees to the faculty for their approval. A list of the option representatives for the current academic year can be found at registrar.caltech.edu/current-students/option-reps. GRADUATE POLICIES AND PROCEDURES ADMISSION TO GRADUATE STANDING Application An application for admission should be completed online through the Graduate Office at gradoffice.caltech.edu/admissions. Admission is granted once a year to a limited number of students who show promise for scholarship and research at the highest level. Completed applications are due between December 1 and January 1, for enrollment at the beginning of the fall term of the following year. Applicants will automatically be considered for financial aid; no additional application is required. To be admitted to graduate standing, an applicant must have received a bachelor's degree, or the equivalent, representing the completion of an undergraduate course in science or engineering related to one of the options offered by the Institute. Applicants must, moreover, have attained a scholastic record and provide recommendations to indicate the ability to pursue, with distinction, advanced study and research. The graduate program thrives on individuals from a diverse range of backgrounds and experiences, and we highly encourage applications from members of groups underrepresented in science and engineering. Graduate admission is covered by Caltech's Nondiscrimination Policy. Graduate Policies and Procedures 353 354 Applicants should refer to the Graduate Office website for additional requirements, a list of supporting documents, and option-specific application deadlines. International Students In order to be admitted for graduate study, students from non-English-speaking countries are expected to read, write, and speak English and comprehend the spoken language. Although not required for admission, applicants whose native language is not English or have not received a degree from a university or college where English is the primary language of instruction, should be able to demonstrate a strong capability in English prior to admission to Caltech. This can be done by self-reporting scores from the Educational Testing Service (TOEFL), Pearson Test of English Academic (PTE Academic), the Cambridge Examinations and the International English Language Testing System (IELTS), or other services that provide a certified English-language proficiency examination. All international students are evaluated upon arrival at Caltech and, if it is determined that additional instruction in English is needed, they will be assigned to an English as a Second Language (ESL) course. To be a candidate for an advanced degree, the student must have clear self-expression in both oral and written English. VISITING STUDENT APPOINTMENTS A limited number of visiting student appointments are made each year. Visiting student status is restricted to students who hold a bachelor's degree and are current graduate students at another institution. The invitation process requires sponsorship by a Caltech faculty member, and requests should be made directly to the Graduate Office, following the visiting student instructions on the Graduate Office website. The dean of graduate studies may limit the number of visiting students in any given year. Visiting students are subject to the Honor System and other Institute policies and are under the purview of the dean of graduate studies. Visiting students are categorized into two main classifications. Special Students Special Students enroll as full-time students (36 units), in a research course and/or coursework numbered 100 or higher, which may be transferred to their home institution. Special Student appointments are allowed for one year, renewable each year up to a maximum of three years. Special Students will not be considered to be working toward a Caltech degree, and courses taken under this program cannot be used to fulfill the requirements for a Caltech degree, nor does registration count toward the minimum residency requirement for an advanced degree. Special Students are eligible for the same privileges as regularly enrolled graduate students, and will be charged for the relevant tuition and fees. Short-term Special Students that do not need academic credit must still enroll in a research class for a minimum number of Information for Graduate Students units and will be billed tuition and fees based on the level of enrollment and the length of stay. For those students who receive a Caltech stipend, tuition remission will be charged to the faculty hosts' supporting grant to cover the tuition and fees assessment. Special Students who do not receive a Caltech stipend will be charged a reduced tuition and fees rate. (For current rates, see the Expense Summary.) Visiting Student Researchers The Visiting Student Researcher status is limited to short-term visits of one month to one year and is not renewable. Visiting Student Researchers are not eligible to enroll in a research course and/or coursework, and will not receive academic credit from Caltech, but will receive a Caltech identification card. Visiting Student Researchers are also required to provide proof of health insurance, vaccinations in accordance with Institute policies, and any other required medical and immunization records for the duration of the visit. Students in this status are not eligible to receive a salary through the Institute payroll, and are not eligible for Caltech privileges that are extended to enrolled students. They may be reimbursed for research-related expenses only, but it is the Caltech faculty host's responsibility to ensure that the supporting grant can be used for such purposes and that there are no restrictions on spending. Students receiving a salary through the Institute payroll and/or requiring a transcript to transfer academic credit must be appointed as Special Students. Exchange Programs Some academic options have formal exchange programs that they have arranged with other institutions. Exchange students must have a visiting student appointment, and the type of appointment will depend upon the terms of the agreement for the particular exchange program. These programs are administered by the option, and requests should be made directly to the Graduate Office following the same procedure for visiting students. GRADUATE RESIDENCE One term of residence shall consist of one term's work of not fewer than 36 units of advanced work in which a passing grade is recorded. Advanced work is defined as study or research in courses whose designated course number is 100 or above. If fewer than 36 units are successfully carried, the residence will be regarded as short by the same ratio, but the completion of a greater number of units in any one term will not be regarded as increasing the residence. In general, the residency requirements are as follows: for Master of Science, a minimum of three terms of enrollment; for the degree of Engineer, a minimum of eight terms of enrollment; and for Doctor of Philosophy, a minimum of 12 terms of enrollment. 355 Graduate Policies and Procedures 356 REGISTRATION Graduate students are required to register for each term, including summer, whether they are taking classes, conducting research, doing independent reading, writing a thesis, or utilizing any other academic service or campus facility. A graduate student must be registered for a minimum of 36 research and/or course units to be classified as a full-time student, and may not enroll in excess of 36 research units. A graduate student who registers for less than 36 total units, or who undertakes activities related to the Institute aggregating more than 62 hours per week (in class, research, and teaching assistantship units), must receive approval in advance from the dean of graduate studies. A petition for this purpose may be obtained from the Graduate Office website and must carry the recommendation of the option representative of the student's major option before submission. Graduate students register during a two-week period each quarter. A late registration fee of $50 is assessed for failure to register on time. Graduate students with a Bursar's bill balance of $1,500 or more may have a hold placed on their registration for the subsequent term the day before online registration opens. The hold will be released once students have paid their bill or worked out a satisfactory payment plan with the Bursar's Office. Before registering, students should consult with their adviser. An adviser is assigned to each entering graduate student by the option representative. In most options, a new adviser is assigned when the student begins research. Only members of the professorial faculty may serve as advisers. With the approval of the dean of graduate studies, any graduate student whose work is not satisfactory may be refused registration at the beginning of any term by the division in which the student is doing their major work. See the section on Satisfactory Academic Progress for more information. In registering for research, students should indicate the name of the instructor in charge, and should consult with the instructor to determine the number of units to which the proposed work corresponds. At the end of the term, the instructor in charge may decrease the number of units for which credit is given if the instructor feels that the progress of the research does not justify the original amount. Students will not receive credit for courses unless they are properly registered. Students themselves are responsible for making certain that all grades to which they are entitled have been properly recorded. Please note that graduate students who enroll in courses numbered below 100 will not receive credit for those courses unless the course(s) is specified in the requirements for a graduate degree as stipulated in the Caltech Catalog. All changes in registration must be reported to the Registrar's Office by the student. Such changes are governed by the last dates for adding or dropping courses as shown on the Academic Calendar. A student may not withdraw from or add a course after the last date for dropping or adding courses without the option's consent, written Information for Graduate Students approval from the instructor of the relevant course, and the approval of the dean of graduate studies. If the withdrawal occurs after Add Day of any term, a W (standing for "withdrawn") will be recorded on the student's transcript for all courses in which the student is enrolled. A grade of W is not included in the computation of the student's grade-point average. General Administrative Requirements Graduate students are required to have continuity in registration, maintain full-time status, make satisfactory progress, and be in residence until all requirements for a degree are fulfilled. This means that students must either be registered, enrolled or on an approved leave from the Institute. Reduced duty status maintains registration for a student who cannot carry a full load due to a medical condition, disability or pregnancy. Registration is required for the term in which the thesis defense is undertaken, with the exception of the first week of each term. Approval of the dean is required for any student seeking to enroll for a subsequent term beyond the defense during the academic year. Once the degree is conferred, further enrollment as a graduate student is not permitted. Detached duty status maintains registration for a student doing research at an external location, such as a national laboratory or another academic institution, for an extended period Students are entitled to at least two weeks' annual vacation (in addition to Institute holidays), and they should arrange their vacation schedules with their research advisers early in each academic year. Any questions should be referred to the graduate studies Office. GRADUATE STUDENT LEAVES OF ABSENCE Petitions for Leave Petition forms for leaves may be obtained from the Graduate Office website and must, before submission to the dean, carry the acknowledgment of the student's option representative and, where appropriate, the thesis adviser. Petitions for medical leave must carry the recommendation of the director of student wellness services or their designee. In case of a lapse in status, readmission must be sought before academic work may be resumed or requirements for the degree completed. While on Leave Caltech considers students on an approved leave to be matriculated; however, students on leave are not currently enrolled and therefore do not enjoy all rights and privileges of enrolled students. Unenrolled students, and accordingly, students on leave, have limited access to Caltech's educational activities, programs, and services. They may not attend classes or labs, live in Institute housing, or access certain student resources, including Student Wellness Services and Residential Life activities, programs, and services during their leave. Career Advising and Experiential Learning (CAEL) is, by default, open Graduate Policies and Procedures 357 358 to all students who have not been permanently separated from the Institute, regardless of leave or enrollment status, unless otherwise revoked by the Director of CAEL or the relevant deans' office. For questions regarding the full scope of these limitations, please contact the Graduate Office. Students may consult with their adviser and otherwise plan for their academic future; however, they will not receive credit for courses unless they are properly enrolled. Students who are on leave are still subject to all Institute policies, including the Institute Sex- and Gender-Based Misconduct Policy. Violations of policy may affect a student's eligibility to re-enroll. Voluntary Leave Personal Leave A student may request a voluntary leave of absence for personal reasons by submitting a personal (non-medical) leave petition to the Graduate Office for approval. International students should consult with the International Student Programs (ISP) office regarding visa implications prior to submitting the leave petition. The dean may grant a personal leave provided (a) the student is making satisfactory academic progress as determined by the student's adviser, (b) the leave is for one year or less, although special circumstances can be considered for a longer leave, and (c) the leave extends over a period that includes at least one full term. A petition to return from a personal leave should be submitted six (6) weeks before the first day of the term for which the student intends to return. Return from a personal leave is subject to the approval of the dean and the student having an approved adviser and ongoing funding to support the student's research. If a student does not anticipate having an adviser upon return, they will need to work with the option representative to arrange for funding and a new adviser in advance of the return. Return will only be granted once an adviser and funding are in place. Medical Leave If a student is unable to complete their coursework or other course of study due to medical reasons, the student may petition for a medical leave of absence by submitting a medical leave petition, endorsed by the director of Student Wellness Services or their designee, to the Graduate Office for approval. International students should consult with the International Student Programs office regarding visa implications prior to submitting the medical leave petition. Medical leaves are expected to extend over a period that includes at least one full term, although special circumstances may be considered for approval of a shorter leave upon the recommendation of a student's treatment team. Students may be required to sign a release of information form authorizing their treatment provider to communicate relevant medical information to representatives within Student Wellness Services and the Graduate Office to facilitate evaluation of the need for the leave Information for Graduate Students and to determine appropriate conditions associated with the leave and establishing expectations for return from the leave. The Institute may impose conditions on return from a medical leave, which may include confirmation from the student's health care provider that the student is following the recommended course of treatment, the student's consent for the provider to discuss the student's condition or progress during the leave with Caltech officials, including representatives of Student Wellness Services and the Graduate Office, and an independent evaluation of the student's readiness to return by a qualified medical professional. Any conditions of return will be specified at the time of the leave approval. A petition to return from medical leave must be submitted six (6) weeks before the anticipated term for which the student intends to return. The return process includes an interview with the director of Student Wellness Services or their designee and the submission of a completed return from medical leave petition and provider recommendation. Students are expected to sign a release of information form authorizing their treatment providers to communicate with Caltech, including representatives of Student Wellness Services and the Graduate Office to determine readiness to return and any recommendations for reasonable accommodations. Return from a medical leave of absence is subject to the final approval of the dean. If the student is permitted to return from the leave, any conditions of return will be communicated to the student in writing. A student returning from a leave for medical reasons will maintain the same academic standing that they had prior to the leave and will be subject to the same academic requirements for maintaining academic progress. Additional information and resources regarding medical leave, including financial and transcript implications, can be found at www.gradoffice.caltech.edu/current/LeavePolicy. Pregnancy Consistent with Caltech policy, the requirements of Title IX, and Section 66281.7 of the California Education Code, students who are unable to complete their coursework or other course of study for a period of time due to a pregnancy, childbirth and related medical conditions are eligible for a pregnancy leave of absence. Students who are pregnant or who have recently given birth are also eligible for reasonable accommodations. Students are not required to take a leave of absence, withdraw, or limit their graduate studies because of pregnancy, childbirth or related medical conditions. However, students who are disabled due to pregnancy, childbirth and related medical conditions are eligible to take a pregnancy leave of absence. The Institute provides up to six (6) weeks of pay to students during a pregnancy leave of absence; an additional 6 weeks of pay is available through family bonding leave (see following section). A pregnant student who wishes to take a pregnancy leave should submit a pregnancy leave petition to the Graduate Office. Medical documentation from the student's treating health care provider may be required. Graduate Policies and Procedures 359 360 A student who chooses to take a leave of absence because they are pregnant or have recently given birth shall be allowed an additional period commensurate with the length of the leave, but not to exceed 12 additional months, to prepare for and take preliminary and qualifying examinations and an equal extension of time toward the normative time to degree while in candidacy for a graduate degree, unless a longer extension is medically necessary. An enrolled student in good academic standing who chooses to take a leave of absence because they are pregnant or have recently given birth shall return to their program in good academic standing following an approved leave period of up to one academic year, subject to the administrative requirements described above, unless there is a medical reason for a longer leave, in which case standing in the graduate program shall be maintained during that period of the The Institute also provides reasonable accommodations to pregnant students consistent with federal and state law. Reasonable accommodations may include allowing pregnant students to maintain a safe distance from hazardous substances, allowing them to make up tests and assignments that are missed for pregnancy-related reasons or excusing of absences that are medically necessary. Bonding Students may take six (6) weeks of family bonding leave with pay. An enrolled student in good academic standing who chooses to take a leave of absence because of the recent birth or adoption of his or her child may request a bonding leave by submitting a bonding leave petition to the Graduate Office for approval. Bonding leave is in addition to pregnancy leave, providing eligible students with a combined total of up to 12 weeks of paid leave. Students returning from an approved bonding leave shall return to his or her program in good academic standing following the leave, subject to the administrative requirements described above. Dependent Care Leave Graduate students may take an unpaid leave for the purpose of full-time dependent care due to child care, school closings, and other dependent needs that require students to take a break from their studies. Students planning on taking this leave should first schedule a meeting with one of the graduate deans. Under this leave, students are eligible to retain existing benefits, including health and dental. If in Caltech housing, students may remain for up to one term while on dependent care leave. Please note that students with dependent care needs may instead request a reduced course load by submitting an underload petition. Information for Graduate Students Involuntary Leave The dean or designee may determine that it is necessary to place a student on an involuntary leave in a variety of circumstances, including when a student demonstrates behavior that poses a threat to health or safety, causes significant disruption to the Caltech community, for the personal safety or welfare of the student involved, as an interim measure, or as a result of a disciplinary action. The dean may impose an involuntary leave in appropriate circumstances, such as where a student's behavior: (1) has, or threatens to, cause significant property damage; (2) significantly disrupts the Caltech community; (3) presents a substantial risk of harm to self or others; (4) indicates the student is unable or unwilling to carry out self-care obligations; or (5) violates a Caltech policy or the honor system. An involuntary leave also may be imposed when the student requires a level of care from the Institute community that exceeds the reasonable accommodations, resources and staffing that the Institute can reasonably be expected to provide for the student's well-being. Review and Decision Process If the conduct has been the subject of an investigation or review under an Institute process or procedure, the dean will consider the findings and conclusions reached in that process. In other circumstances described above, in making an informed decision to place a student on involuntary leave, the dean will conduct an individualized assessment and consider relevant information including information provided in a timely manner by the student. The dean may consult with other Institute personnel, including but not limited to Security and Residential Life personnel, faculty, staff and other individuals or departments. If appropriate and feasible, the dean may seek cooperation and involvement of parents or guardians of the student. Medical information, including medical information provided in a timely manner by the student, may be considered if the behavior is associated with a physical or mental condition. In appropriate cases, the dean may consult with the director of Student Wellness Services or their designee and/or require a physical or mental evaluation from a health professional if the dean believes such an evaluation is necessary in order to make an informed decision. Students are expected, if necessary, to sign a release of information to facilitate discussions between Caltech and the health professional conducting the evaluation. The dean will also consider whether relevant risk factors can be eliminated or reduced to an acceptable level through reasonable accommodation. Written Decision The student will be advised in writing of the decision to impose an involuntary leave. The dean may stipulate conditions that must be met before the student may return. An involuntary leave may be a permanent separation from the Institute (i.e. expulsion); for a specific duration; or until certain conditions have been met. If the involuntary leave is not a permanent separation, the student will be advised of the Graduate Policies and Procedures 361 362 length of the leave and/or any conditions for return. Emergency Leave If the dean determines that a student's continued presence is likely to pose a substantial risk to the safety and well-being of the student or others, the dean may place the student on an emergency interim leave before a final determination is made. The dean will make reasonable attempts to meet with the student and consider relevant information provided by the student, if available within the timeframe needed to make a decision, before deciding on an emergency interim leave. An emergency interim leave will remain in effect until a final decision has been made. Return from Leave A student on involuntary leave will not be allowed to return until the dean makes a fact-specific assessment of the circumstances, considers relevant risk factors, and concludes that the student does not pose a significant disruption to the functioning of the Institute community and/or does not pose a substantial risk to the health and safety of the student or others. The dean will consider relevant information, including information provided by the student. In cases where a student has a physical or mental condition associated with the behavior triggering the leave, the dean will also consider whether the relevant risks can be eliminated by a reasonable accommodation. The dean may consult with other Institute administrators, as appropriate, in making their decision. The student will be notified in writing of the dean's determination of whether the student will be permitted to return from a leave, will not be permitted to return from the leave, or will be permanently separated from the Institute. If the student is permitted to return from the leave, any conditions of return will be communicated to the student in writing. Appeal If a decision by the dean to place a student on involuntary leave is imposed as a sanction resulting from a finding of responsibility under an Institute process or procedure, appeal rights and limitations, such as limitations on grounds for appeal, are governed by the applicable Institute process or procedure. In all other cases, a decision by the dean to place a student on involuntary leave may be appealed in writing within 10 days to the vice president for student affairs (or designee). GUIDELINES FOR GRADUATE STUDENT ADVISING The relationship between a faculty adviser and graduate student should be founded on mutual respect and open communication. Advisers and students should discuss the nature of their working relationship early and continue this discussion throughout their period of collaboration to ensure mutually understood and compatible expectations. These discussions should be frequent and open, and should include not only work, research goals, and performance reviews, but also change of status, time for personal and family Information for Graduate Students responsibilities, time off, and concerns about academic or work situations. Both the student and adviser have the obligation to initiate meetings as necessary to ensure the success of the relationship. After achieving candidacy, each Ph.D. student should be assigned a thesis advising committee consisting of a minimum of three professorial faculty members. This committee typically meets at least once a year beginning after candidacy or the fourth year of graduate study. The graduate student-faculty adviser relationship should be guided by norms of fairness and professionalism. Both faculty and graduate students should avoid relationships that conflict with their respective roles and duties at Caltech. Both are bound by the prevailing policies prohibiting discrimination and harassment (Nondiscrimination Policy Sex- and Gender-Based Misconduct, and Unlawful Harassment). Concerns relating to academic or work situations should be raised promptly between the persons directly involved, and handled informally if possible. Both students and advisers have the responsibility to raise and address concerns and conflicts promptly, honestly, and in a manner that conforms with academic integrity and professionalism. Caltech policy requires that students' concerns be addressed fairly and promptly, and prohibits retaliation or discrimination against students for appropriately voicing or raising a concern. If a problem remains unresolved or if direct discussion is not possible, a student can seek assistance from division officers (e.g., option representatives) or the graduate deans. At any time, a student may request that discussions remain confidential. For more details about sources of assistance, consult the graduate option regulations and the Student Problem Resolution Process. PART-TIME PROGRAMS Part-time graduate study programs at the Institute are for master's seeking graduate students who cannot devote full time to their studies and such students are subject to the following rules: Degree Programs • Applicants for the part-time master's program must submit a regular application form acmpanied by a detailed plan for meeting the course requirements for the degree. • Any research work done for academic credit shall be supervised by a Caltech faculty member. • In general, students admitted to the part-time program are required to take at least 27 units of graduate course work and/or research each term. • The part-time program is limited to two years of academic residence. • Any option at the Institute retains the right to not participate in the program or to accept it under more stringent conditions. Graduate Policies and Procedures 363 364 Non-degree Programs Caltech employees, both campus and JPL, are eligible to apply to take one or more graduate courses for credit. Participants in this program will not be considered to be working toward a Caltech degree, in contrast to the part-time program for graduate degrees described above, and courses taken under this program cannot be used to fulfill the requirements for a Caltech degree. At least one month prior to the start of the term, the employee should have an initial discussion with the option representative of the option in which the course is to be taken. Application should be made to the Graduate Office by completing the special form provided for this purpose, and providing a transcript of academic work and a letter of recommendation. The employee must meet the prerequisites for the course, and must obtain the written permission of the instructor. The decision on admission to take each course will be made by the course instructor and the option representative, with final approval by the dean of graduate studies. Taking an additional course at a later time will require full reapplication. It is the employee's responsibility to arrange a revised work schedule with the appropriate supervisor and approval of the employee's supervisor is required. Part-time non-degree students are subject to the Honor System and are under the purview of the dean of graduate studies. They may take only courses numbered 100 or higher and research courses are excluded from the program. For courses in which a letter grade is offered, these students may not register to receive a pass/fail grade in the course, nor can credit for the course be obtained by examination. The option may limit the number of non-degree students admitted to any one course. RESPONSIBLE CONDUCT OF RESEARCH Caltech researchers are expected to adhere to the highest professional standards in the conduct of research. Faculty members are charged by the Institute with the responsibility to safeguard the basic principles of research integrity, academic freedom, and public interest. Students are expected to also follow these same principles. When government funds are involved in the support of research, investigators are required to take specific steps to adhere to all rules and regulations of the government and sponsoring agencies. Students are required to have specific training in research ethics and integrity as well as conform to standards established by research supervisors or their laboratories. There are two situations in which this is mandated by federal law. National Institutes of Health Students that are funded through NIH grants, work with human or vertebrate animal subjects, or are required as part of their academic option's curriculum, have to meet a NIH requirement for training in specified areas as described in the Caltech Guide to Sponsored Research. In order to meet the NIH requirement, Caltech requires that all trainees supported by NIH funds take Biology course 252 "Responsible Conduct of Research." Information for Graduate Students National Science Foundation Training in Responsible Conduct of Research is also required of students funded on NSF awards, including the GRFP program. In order to satisfy the NSF mandate, Caltech requires that students supported from NSF funds as described above shall take the online course on Research Ethics Education (CITI). If a student can document having passed a similar, qualifying program at another institution, Caltech may accept that in lieu of completing Caltech's program. You must submit documentation in the form of a transcript or certificate to the Graduate Office to receive credit for previous work. A passing grade in Bi 252 is an acceptable alternative to passing the CITI online Responsible Conduct of Research course. CONFLICT OF INTEREST AND COMMITMENT OF GRADUATE STUDENTS The Institute has a long-standing philosophy that all graduate students should be given the opportunity to be completely focused on graduate studies and research. This is one of the unique aspects of Caltech's graduate school and a key factor in the high level of productivity and accomplishment by our graduate students. To enable this, the faculty and Institute provide financial aid in the form of fellowships, tuition scholarships, graduate teaching, and research assistantships. The stipend and salary levels for students are modest but sufficient for economical students to live debt-free during their graduate studies. The financial support provided by the Institute and the requirements for continuous enrollment also enable almost all students to complete the degree programs in a timely manner. In turn, the Institute expects that graduate students should be 100 percent committed to graduate studies while enrolled in a graduate program. Graduate students are expected to be continuously enrolled full-time, year-round, until they complete their degree program. In addition, graduate students should not accept employment, start or run a business, or engage in any activity inside or outside of the Institute that creates a conflict of commitment with their full-time, degree-seeking status. Exceptions There are some very limited exceptions to this policy. The Institute encourages extracurricular activities that provide service to the community and do not impact the student's academic progress or full-time status. The Institute also recognizes that some students desire to gain experience as instructors or work in an educational or research setting outside of Caltech. Outside Employment Students must have the approval of their adviser, the option representative, and the dean of graduate studies in order to engage in any outside employment activities. Once permission is granted, students may engage in employment of up to one day per week (8 hours) for a limited-duration for these purposes (see Financial Graduate Policies and Procedures 365 366 Assistance). Students must declare to the dean of graduate studies all external funding, including fellowships, awards, or employment, part- or full-time, which supports their academic activities/research. The Institute may adjust Institute financial aid allocated accordingly to maintain the stipend within the Institute guidelines and to recover tuition from outside sources whenever possible. A student's financial aid and/or Institute salary may be reduced if the income is significant, and in the case of long-term, unreported employment activities, the student may be asked to repay financial aid. Students may not hold a position of line responsibility in an outside enterprise for pay or profit. International students on a visa are further required to consult with the office of International Student Programs to determine eligibility. Students must provide official documentation of the financial award or salary, as well as submit a request to the Graduate Office before accepting any employment. Permission to engage in outside employment is contingent on the student maintaining satisfactory academic progress as determined by the dean of graduate studies in consultation with the adviser and option representative. Non-Paid Activities Students must have the approval of their adviser, the option representative, and the dean of graduate studies in order to engage in or continue in any outside activities wherein the time committed to those activities may impact the student's progress toward completion of degree requirements. Leave of Absence Students who work full-time off campus in a commercial organization are expected to take a personal leave of absence. They will not be enrolled during this time, and the "clock" will stop on their graduate career. Taking a personal leave in order to work requires the endorsement of the adviser and permission of the dean of graduate studies. A personal leave is always required when the job is not directly related to thesis research. Students who need to stop their studies to address health issues should take a medical leave of absence, which requires the endorsement of Student Wellness Services as well as the permission of the dean of graduate studies. Detached Duty In some cases, a student may be engaged in research at an external laboratory or research institute under the supervision of a Caltech faculty adviser, and conducting research that is directly related to their degree program. Another situation is that a student may be invited to be a visiting researcher at another university, or the student may need to be working with a faculty member who has left Caltech and is working at another institution. Students may go on detached duty rather than on leave of absence if the adviser and dean of graduate studies approve and there is documentation of a research program integral to their thesis project and appropriate mentoring. Students on detached duty should have Information for Graduate Students completed their residency requirements and advanced to candidacy prior to moving to the host institution. The student should submit the documentation and a petition form to the Graduate Office. Students on detached duty are still enrolled as full-time students but are in residence at another location. They may be paid by Caltech or through another organization. It is the student's responsibility to continue to be in good standing, and registered and in full-time status while on detached duty. Detached duty petitions are usually valid for a limited time, less than one year, and may be renewed upon request. Consulting and Other Entrepreneurial Activities Graduate students are sometimes approached to perform paid consulting or are inspired to be entrepreneurs. In these cases, students have to be exceptionally careful not to create conflicts of commitment or conflicts of interest through these activities. Students considering these activities should familiarize themselves with the Caltech policies on conflict of interest, outside employment or business activity, and the Caltech ethics handbook. Students may not engage in any consulting activities that interfere with their primary graduate student activities of learning and research. Scrupulous care must be taken to ensure that Caltech's name and its letterhead are used neither directly in any correspondence between the student and the company the student wishes to consult for, nor in any reports that student may submit to the company. Of particular concern are students consulting or accepting employment from a company in which their adviser or other Caltech faculty member is directing a student's research and has a significant interest or is a paid consultant. In such cases, the division chair must approve any student involvement in the activities performed for the company. The student must submit a written disclosure, and a conflict management plan will be put in place. Graduate students should not enter into any consulting or employment agreement with intellectual property encumbrances or confidentiality provisions that are in conflict with the student's commitments to Caltech or that may compromise academic progress. Please refer to the Graduate Office website for the complete policy and regulations regarding conflicts of commitment and interest. If there are any questions about the propriety of any outside activity or agreements, this should be discussed with the Graduate Office and, if necessary, the Office of Research Compliance and the Office of the General Counsel. WORKING AT SPECIAL LABORATORIES Students who desire to take advantage of the unique opportunities available at one of the special laboratories (e.g., JPL) for Ph.D. thesis work may be allowed to do so provided that they maintain good contact with academic life on campus, the laboratory involved commits financial support for the duration of the thesis research, and all Caltech graduate thesis research carried out at a special laboratory is under the supervision of Caltech faculty members. Graduate Policies and Procedures 367 368 A student's request to carry out thesis work at a special laboratory should be formally endorsed by the appropriate committee of his or her option and by the special laboratory, on a petition submitted through the option representative to the dean of graduate studies. The special laboratory should recognize its commitment of special equipment or any other resources required for the thesis work. Approval by the special laboratory should also indicate that the thesis topic is a sensible one, and that it is not likely to be preempted by the laboratory. A student may take similar advantage of unique opportunities at a corporate or governmental research and development facility under the same conditions, providing that there exists a formal written agreement between the R&D; facility and the student's thesis adviser, and that advance written approval is obtained from the dean of graduate studies. Such training may in some cases involve full-time employment at the laboratory for a limited period of time for the purpose of engaging in the essential data collection that is integral to a student's thesis. Typically, such students who are not in a local laboratory are placed on detached duty status. Employment by a special laboratory of a graduate student for work not connected with the thesis should be regarded as equivalent to other outside employment. EXCHANGE PROGRAM WITH SCRIPPS INSTITUTION OF OCEANOGRAPHY An exchange program with the Scripps Institution of Oceanography (SIO), University of California, San Diego, permits Caltech graduate students to enroll in and receive credit for graduate courses offered by SIO. Arrangements should be made through the student's major option and the Graduate Office. The student must obtain the advance approval of the instructors of courses to be taken at SIO. In some cases, arrangements may be made for the student to be temporarily in full-time residence at SIO. Thesis research done partly at SIO may be arranged directly by the student's option and the staff of the appropriate research laboratories at SIO, without the necessity of enrolling for SIO courses designated for research; in this case the student will continue to be under the supervision of the Caltech thesis adviser and will enroll for Caltech research units. Information for Graduate Students GENERAL REQUIREMENTS FOR GRADUATE DEGREES DEGREE OF MASTER OF SCIENCE The Master of Science degree is a professional degree designed to prepare a student for teaching, for further graduate studies, or for more advanced work in industry. Detailed requirements are based primarily on professional studies, and the program should be planned in consultation with the faculty in the appropriate discipline. Under normal circumstances, the requirements for the master's degree can be completed in one academic year. Students must declare candidacy for the master's degree no later than the academic year in which the final degree requirements have been met or upon separation from the Institute. Students who are pursuing a doctoral degree and obtain a Master's along the way, must declare candidacy for the Master's no later than two weeks prior to conferral of the Ph.D. A student who enters the Institute holding a master's degree from another institution will not normally be awarded a second master's degree in the same field. A student will not be awarded two master's degrees from the Institute. Special regulations for the master's degree are listed under each graduate option. Several options do not offer a master's degree except in special circumstances. Residence and Units of Graduate Work Required At least one academic year of residence at the Institute and a minimum of 135 units of graduate work at the Institute subsequent to the baccalaureate degree are required for the master's degree. Included in these units are at least 27 units of free electives or of required studies in the humanities numbered 100 or above. Advanced courses taken while enrolled as a Caltech undergraduate student in excess of the bachelor's degree requirements may be counted toward the master's degree requirements with the approval of the academic option representative and the dean of graduate studies. To qualify for a master's degree, a student must complete the work indicated in the section on special regulations for their option with a grade-point average for the approved Master's candidacy courses of at least 1.9. In special cases, with the approval of the instructor, option representative, and the dean of graduate studies, courses taken elsewhere before enrollment at the Institute may be offered in place of specifically required courses. An examination may be required to determine the acceptability of such courses. Course credit, if granted, shall not count toward the 135-unit and residency requirements. General Requirements for Graduate Degrees 369 370 Admission to M.S. Candidacy By the third term of the academic year in which the student expects to receive the degree, candidates should have completed a plan of study in Regis, which must have the approval of the option representative and, in some cases, of the research adviser. This approved plan of study will constitute requirements for the degree. Any modifications to the plan of study must be approved by the option representative no later than two weeks before the degree is to be conferred. Some options require a thesis or research report in addition to course requirements. The thesis or research report must be approved by the research adviser and option representative no later than two weeks before the degree is to be conferred. For additional information and option-specific requirements, please refer to the section "Special Regulations for Graduate Options." Joint B.S./M.S. Degree In exceptional cases, undergraduate students may be eligible to pursue a joint B.S./M.S. program of study to be completed within the four years (12 terms) of the undergraduate program. Students should contact the graduate option representative to find out if the joint B.S./M.S. degree is offered in a particular option. If so, students must follow the normal procedures for admission to the graduate program. Students admitted to the joint B.S./M.S. degree must complete a minimum of 486 units for the B.S. program and an additional 135 units for the M.S. program with no overlapping of courses. In addition, a written plan of study must be submitted to the Registrar's Office for approval no later than the fall term of the senior year. The plan of study should provide detail of the courses that are proposed to satisfy each degree requirement within the 12 terms of the B.S. program and once approved shall constitute the requirements for the degree. Any changes to the plan require written approval by the Registrar. If not completed within the four years, students will be removed from the joint program and they, and all their courses, will be attached to the B.S. program. Students enrolled in the joint B.S./M.S. degree will be considered undergraduate students and will not be eligible for graduate financial aid, graduate housing, or other graduate student privileges. ENGINEER'S DEGREE Engineer's degrees are awarded in exceptional circumstances. The work for an engineer's degree must consist of advanced studies and research in the field appropriate to the degree desired. It must conform to the special requirements established for that degree and should be planned in consultation with the members of the faculty concerned. Students who have been admitted to the terminal master's degree and wish to pursue further studies leading toward either the engineer's or the Ph.D. degree must file a petition (and in some cases must file a new application) to continue graduate work toward the desired degree. Students who have received an engineer's degree will not be admitted for the Ph.D. Information for Graduate Students Residence At least eight terms of graduate residence subsequent to a Bachelor's degree equivalent to that given by the Institute are required for an engineer's degree. Of these, at least three terms must be at Caltech. It must be understood that these are minimum requirements, and students must often count on spending a somewhat longer time on graduate work. To qualify for an engineer's degree, a student must complete the work prescribed by the supervising committee with a grade-point average of at least 1.9. Research work and the preparation of a thesis must constitute no fewer than 55 units. More than 55 units may be required by certain options, and the student should determine the particular requirements of their option when establishing a program. Admission to Candidacy Before the midpoint of the first term of the academic year in which the student expects to receive the degree, they must complete a proposed plan of study and, in consultation with the chair of the appropriate division, will select a committee comprised of at least three members of the professorial faculty to supervise the student's work and to certify its satisfactory completion. The student should consult with this committee in planning the details of their work. The plan of study shall then constitute the requirements for the degree. Any modifications must be approved by the option representative at least two weeks before the degree is conferred. The student will be admitted to candidacy for the degree when the supervising committee certifies (a) that all the special requirements for the desired degree have been met, with the exception that certain courses of not more than two terms in length may be taken after admission to candidacy; (b) that the thesis research has been satisfactorily started and can be finished at the expected date; (c) that the candidate demonstrates competence in oral and written English. Admission to candidacy should be obtained by the midpoint of the term in which the degree is to be granted, but no later than the academic year in which the final degree requirements have been met or upon separation from the Institute. Thesis At least two weeks before the degree is to be conferred, each student is required to submit a thesis in accordance with the regulations that govern the preparation of doctoral dissertations. These regulations may be obtained from the Graduate Office website. The use of "classified" research as thesis material for any degree will not be permitted. Exceptions to this rule can be made only under special circumstances, and then only when approval is given by the dean of graduate studies before the research is undertaken. General Requirements for Graduate Degrees 371 372 Examination At the discretion of the option in which the degree is desired, a final examination may be required. This examination would be conducted by a committee appointed by the candidate's supervising committee. DEGREE OF DOCTOR OF PHILOSOPHY The degree of Doctor of Philosophy (Ph.D.) is conferred by the Institute primarily in recognition of breadth of scholarship, depth of research, and the power to investigate problems independently and efficiently, rather than for the completion of definite courses of study through a stated period of residence. The work for the degree must consist of research and the preparation of a thesis describing it, and of systematic studies of an advanced character, primarily in science or engineering. In addition, the candidate must have clear self-expression in both oral and written English. Subject to the general supervision of the Committee on Graduate Study, the student's work for the Ph.D. degree is specifically directed by the division in which they have chosen the major subject. Each student should consult with their division concerning special divisional and option requirements. Admission With the approval of the dean of graduate studies, students are admitted to graduate standing by the option in which they choose their major work toward the Ph.D. degree. In some cases, applicants for the Ph.D. may be required to complete requirements for the M.S. degree first; however, this is not a general prerequisite for the Ph.D. Students who have received an Engineer's degree will not be admitted for the Ph.D. degree. A student who holds a Ph.D. or the equivalent from another institution will not normally be admitted to graduate standing at Caltech to pursue a second Ph.D. degree. A student will not normally be awarded two Ph.D. degrees from the Institute. Minor Programs of Study The Institute does not require a minor for the Ph.D. degree, but the individual options may have minor requirements as part of their requirements for the major. A student may undertake a minor program of study in most options as specified in this catalog under the section "Special Regulations of Graduate Options." Completion of a minor program of study is recognized on the diploma by the statement "...and by additional studies constituting a minor in [name of option]." A minor program of study should be at a level of study in the minor substantially beyond that typically acquired by students as part of their major requirements. Most options require 45 units or more, including at least one 200-level course and a coherent program of the supporting 100-level courses. The faculty of the minor option may approve a proposed minor program on the basis of overall class performance and/or by an oral examination. Information for Graduate Students Detailed requirements for minor options are listed under the individual options. Students cannot use courses required by their major option in fulfillment of the minor requirement. Residence At least three academic years (12 terms) of residence subsequent to a baccalaureate degree equivalent to that given by the Institute are required for the Ph.D. Of this, at least one year (4 terms) must be in residence at the Institute. It should be understood that these are minimum requirements, and students must usually count on spending a somewhat longer time in residence. A student whose undergraduate work has been insufficient in amount or too narrowly specialized, or whose preparation in their special field is inadequate, should plan upon spending increased time in work for the degree. However, no student will be allowed to continue work toward the Ph.D. degree for more than six academic years (24 terms) of graduate residence, without a petition approved by the dean of graduate studies. This petition must include a plan and schedule for completion, agreed upon and signed by the student, the thesis adviser, and the option representative. Registration Continuity of registration must be maintained until all requirements for the Ph.D. have been completed, with the exception of authorized leaves. Registration is typically required for the term in which the thesis defense is undertaken. Thesis Advisers and Committee Chairs The thesis adviser must be a professorial faculty member, defined as professor, associate professor, or assistant professor on a full-time, tenure-track appointment at Caltech. Research faculty and emeritus faculty can supervise research, but the official thesis adviser must be a member of the professorial faculty. Expectations for the relationship between graduate students and faculty advisers are discussed under Guidelines for Graduate Student Advising Progress through the graduate program is monitored in part by the candidacy, thesis advisory, and thesis examination committees detailed in the following sections. Each committee has a chair who is responsible for running the meeting, summarizing the outcome, and working with the graduate student and adviser as appropriate. The chair of each committee is a professorial faculty member distinct from the adviser. Admission to Candidacy On the recommendation of the option concerned, the dean of graduate studies will admit a student to candidacy for the degree of Doctor of Philosophy after the student has been admitted to work toward the Ph.D. and has been in residence at least one term; has initiated a program of study approved by the major option and, if needed, by the minor option; has demonstrated, by written or oral examination, a comprehensive grasp of the major and minor subjects and of subjects fundamental to them; has displayed the ability for clear General Requirements for Graduate Degrees 373 374 self-expression in both oral and written English; and has shown ability in carrying on research in a subject approved by the option concerned. Option regulations concerning admission to candidacy are given in a later section. Depending upon option regulations, candidates will either be assigned a candidacy committee by the option representative or must independently select appropriate members to serve on the candidacy committee. A candidacy committee consists of a minimum of three members, two of whom must be professorial faculty. Emeritus faculty, research faculty, JPL staff and external scholars may serve on the candidacy committee, with approval of the option representative and the dean of graduate studies in advance of the candidacy examination. The student should ensure that all members of the committee are available during the examination period and that they are willing to provide timely and appropriate feedback. A student not admitted to candidacy by the end of the third year or twelfth term of graduate residence at the Institute must petition the dean of graduate studies for permission to register for further work. Candidacy (and permission to register) may be withdrawn by formal action of the option from a student whose research is not satisfactory, or for other compelling reasons. However, the option must petition through its division chair to the dean of graduate studies before taking such action. Thesis Advisory Committee Each Ph.D. student is assigned a Thesis Advisory Committee consisting of a minimum of three professorial faculty members. Emeritus faculty, research faculty, JPL staff and external scholars may serve on the thesis examination committee with approval of the option representative and the dean of graduate studies. Following candidacy, or by the fourth year of graduate study, a student will have an annual meeting as specified by the option with either the thesis advisory committee, the committee chair, or the option representative (if not the advisor), to discuss progress towards completing the thesis and future plans. Thesis Examination Each Ph.D. candidate shall undergo broad oral examination on the major subject, the scope of the thesis, and its significance in relation to the major subject. The thesis examination, subject to the approval of the dean of graduate studies, may be taken after admission to candidacy whenever the candidate is prepared; however, it must take place at least three weeks before the degree is to be conferred. The thesis examination may be written in part, and may be subdivided into parts or given all at one time at the discretion of the options concerned. The student must declare their intent to defend by completing the examination notification in Regis not less than two weeks before the date of the examination. A thesis examination committee consists of four members, with a minimum of three professorial faculty. Emeritus faculty, research faculty, JPL staff and external scholars may serve on the thesis examination committee with Information for Graduate Students approval of the option representative and the dean of graduate studies in advance of the thesis examination. Thesis At least two weeks before the final oral examination, the candidate should provide a draft copy of a completed thesis to the Graduate Office for proofreading and to the members of the thesis examination committee. The date of the examination and the composition of the thesis examination committee should be posted in Regis at least two weeks before the final defense is scheduled. In general, registration is required for the term in which the thesis defense is undertaken. Approval of the dean of graduate studies is required for any student seeking to enroll for a subsequent term following the thesis defense. This enrollment will be limited to one term, and cannot be granted after the degree has been conferred. A student not receiving Caltech funding, may petition the dean of graduate studies for a tuition waiver if the student schedules the examination by the third Friday of the term in which the examination will be taken. Before uploading the final, corrected thesis to CaltechTHESIS, it is the candidate's responsibility to obtain approval of the thesis by the option representative and all members of the thesis examination committee. The last date to deposit the thesis in it's final form to CaltechTHESIS is June 1 if the thesis defense occured during the current academic year. Students who cannot meet this deadline are required to petition the dean of graduate studies for an extension to keep the thesis active. In such cases, the degree would be conferred in the following year's commencement. It is required that all Ph.D. candidates submit an electronic copy of their dissertation, which the Caltech Library will then archive and make available online as part of the Networked Digital Library of Theses and Dissertations (NDLTD), an international organization that allows researchers to globally search a database of electronic theses and dissertations. For special option regulations concerning theses or the exam composition, see specific graduate options. With the approval of the option concerned, a portion of the thesis may consist of one or more articles published jointly by the candidate and members of the Institute staff or other coauthors. In any case, however, a substantial portion of the thesis must be the candidate's own exposition of their own work. The use of "classified" research as thesis material for any degree is not permitted. Exceptions to this rule can be made only under special circumstances, and then only when approval is given by the dean of graduate studies before the research is undertaken. Regulations and directions for the preparation of theses may be obtained from the Graduate Office website, and should be followed carefully by the candidate. Thesis templates are also available on the Library website, as is information regarding thesis deposits, embargo policies and copyright issues. General Requirements for Graduate Degrees 375 376 SATISFACTORY ACADEMIC PROGRESS In order to continue in a degree program and to receive financial aid at Caltech, graduate students must maintain satisfactory academic progress toward completion of their degree. A fulltime graduate student must register for (and complete) 36 units per term, including the summer term. Continuity of registration must be maintained until all requirements for the degree being sought have been completed, with the exception of authorized sabbaticals. The Master of Science degree requires at least three terms of residence at the Institute and a minimum of 135 units of graduate work with a grade-point average of at least 1.9. A master's degree cannot take more than two years without a petition approved by the dean of graduate studies. The Engineer's degree must consist of advanced studies and research in the field appropriate to the degree desired. At least eight terms of graduate residence are required with a minimum 1.9 overall grade-point average. The Engineer's degree cannot take more than 12 terms to complete without a petition approved by the dean of graduate studies. For the Doctor of Philosophy, at least 12 terms of residence are required, but the necessary study and research typically can be completed in six years or less. The work for the degree consists of research and the preparation of a thesis describing it, and of systematic studies of an advanced character, primarily in science or engineering. All doctoral students must have a thesis adviser to remain in good academic standing. The timeline for securing a thesis adviser varies by the specific graduate option (see Special Regulations for Graduate Options). A student's thesis adviser must be an active member of the Caltech professorial faculty and is responsible for general advising, approving and guiding a research topic, monitoring the student's progress until all degree requirements have been met, and in most cases, providing student support for the duration of the degree program. The requirements for each degree include special regulations established by each option and detailed in the Institute Catalog for the year of initial registration. Many options require a C grade or better in particular courses or groups of courses. Hence, a limited number of courses may be repeated while still maintaining a status of satisfactory academic progress and would count toward the 36-unit-per-term requirement. Approval of the dean of graduate studies is required before dropping any course that brings a student below 36 units. The treatment of incomplete grades and withdrawals is specified in Grades and Grading. Satisfactory academic progress is checked each academic term by the Graduate Office. The special regulations for the options typically include the completion of specific courses, oral and/or written examinations, petitions, research requirements, etc., by specific times. Satisfactory academic progress is judged by the options against these regulations, and revocation of permission to register may be recommended by the option to the dean of graduate studies prior to or in response to the Information for Graduate Students student's petition for admission to candidacy. Further, even after admission to candidacy, the candidacy (and permission to register) may be withdrawn by formal action of an option for a student whose research is not satisfactory, or for other compelling reasons. However, the option must petition through its division chair to the dean of graduate studies before taking such action. A decision to revoke or withdraw permission to register may be appealed in writing within ten days to the vice president for student affairs or designee. A Ph.D. student who has not been admitted to candidacy by the beginning of the fourth year (12 terms) must petition the dean of graduate studies for permission to register for further work. In addition, no Ph.D. student will be allowed to register for more than 24 terms without a petition approved by the dean of graduate studies. This petition must include a plan and schedule for completion, agreed upon and signed by the student, the Thesis Advisory Committee chair, and the option representative. GRADUATE EXPENSES The tuition and fees charge for all students registering for graduate work is currently $60,657.00 per academic year, payable at the beginning of each term, fall (9/27/2022), winter (1/4/2023), and spring (4/3/2023). Graduate students who cannot devote full time to their studies are allowed to register only under special circumstances. Students desiring permission to register for fewer than 36 units must therefore petition the dean of graduate studies for an underload. The payment of tuition by graduate students is required (a) without reference to the character of the work by the student, which may consist of research, independent reading, or writing a thesis or other dissertation, as well as attendance at regular classes; (b) without reference to the number of terms in which the student has already been in residence; and (c) without reference to the status of the student as an appointee of the Institute, except that members of the academic staff of rank of instructor or higher are not required to pay Unpaid Bills All bills owed the Institute must be paid when due. Any student whose bills are past due may be refused registration for the following term. All graduate students with an outstanding bursar's bill balance of $1,500.00 or more will have a hold placed on their registration for the subsequent term the day before online registration opens. Diplomas will not be released until the bursar's account is paid in full. Caltech ID Card Charges If a graduate student owes more than $1,500.00, the student's charging privileges will be suspended. Charging privileges will be reactivated once students have paid their bill in full with the Bursar's Office.

Graduate Expenses 379 380 Health Services Health services available to graduate students are explained in section one of this Catalog. FINANCIAL ASSISTANCE Caltech offers in each of its options a number of fellowships, tuition scholarships, and graduate assistantships. In general, tuition scholarships may be for full or partial tuition charges; assistantships provide stipends; and fellowships often provide both tuition scholarship awards and stipends. Graduate assistants are eligible for tuition awards. Appointments to fellowships, scholarships, and assistantships are decided yearly by the student's academic option. Graduate students receiving any form of financial award from the Institute are required to report to the dean of graduate studies any financial aid from other sources. With prior written approval from the dean of graduate studies, students may be allowed to accept outside employment if the time commitment does not interfere with their graduate studies. The number of hours per week spent on outside employment must be reported to the dean of graduate studies. GRADUATE ASSISTANTSHIPS Graduate assistants help with teaching, laboratory work, or perform research of a character that affords useful academic experience while permitting a full academic schedule of courses. The specific research and teaching obligations of graduate assistants are agreed upon with the adviser. Caltech graduate students often receive a combination of teaching and research assistantships; however, the total work commitment cannot exceed 20 hours per week during the academic year. Summer appointments can be greater, with assignments up to 40 hours per week. A graduate student who undertakes activities related to the Institute aggregating more than 62 hours per week (in class, research assistantship, and teaching assistantship hours) must petition the dean of graduate studies. Graduate assistant stipends are based on four quarters paid monthly throughout the year. Students are also entitled to two weeks of annual vacation and Institute holidays. Students should prearrange their vacation schedule with their adviser. When necessary, graduate assistants may arrange for medical leave, pregnancy leave, bonding leave, or personal leave. Any questions should be referred to the dean of graduate studies. Teaching Assistantships A full teaching assistantship usually requires 20 hours per week to be devoted to teaching and to the related activities of class preparation, grading, and consulting with students. In general, teaching obligations are confined to the 12 weeks of the academic terms, excluding summer. A student may not be a teaching assistant for a course in which they are enrolled. Only teaching assistants with good oral Information for Graduate Students English and who have fulfilled the Institute English proficiency requirement are permitted to teach sections. All teaching assistants, including undergraduate students with teaching responsibilities, are required to attend teaching-assistant training before payment can be processed. Training sessions are conducted by the Center for Teaching, Learning, and Outreach (CTLO) and occur in the first week of the fall term, typically during orientation, and at least once per term. Teaching assistants must familiarize themselves with Caltech's policy on Unlawful Harassment and follow other policies related to teaching discussed in the required training. Classes should foster academic achievement in a "hassle-free" environment. Teaching assistants should not attempt to date a student in their class, and should disqualify themselves from teaching a section in which a spouse or current partner is enrolled. Time craduate Saies orce for adional prices information at www.gradoffice.caltech.edu/financialsupport/assistantships. Research Assistantships Research assistantships typically are 20 hours per week during the academic year, but can be as much as 40 hours per week during the summer. The specific duties are decided upon by the adviser. Graduate Scholarships, Fellowships, and Research Funds The Institute awards endowed fellowships and scholarships for tuition and/or stipends to graduate students of exceptional ability. Students are also strongly encouraged to apply for scholarships and fellowships from federal and private agencies and organizations to support their graduate studies. Loans Several types of loans are available to graduate students. To qualify for any of these, a student must demonstrate financial need and must maintain satisfactory academic progress in the course of study for which they are enrolled. Application forms and further information are available from the Financial Aid Office. Refund and Repayment Policy Caltech has established an equitable refund policy for students who find it necessary to withdraw or take a sabbatical from the Institute. Students who officially withdraw or take a sabbatical from the Institute during an academic term may receive a tuition refund. Students living in Caltech housing may also be eligible for a partial refund from the Housing Office. When granting refunds to financial aid recipients or graduate assistants, it is Caltech's policy to return the refund, in most cases, to the original account. Financial Assistance 381 382 PRIZES AND AWARDS Advocating Change Together (ACT) Award Given by the Caltech Y, this award allows students to learn about a lobal, national, or local issue by immersing themselves with activisi forking on a cause over the summer and then challenges them t educate others by creating and leading programs designed to raise awareness on campus the following year.

SPECIAL REGULATIONS FOR GRADUATE OPTIONS AEROSPACE (AE) Aims and Scope of the Graduate Program The Institute offers graduate programs in aerospace leading to the degrees of Master of Science in Aeronautics and Space Engineering, and Doctor of Philosophy in Aeronautics and Space Engineering. The programs are designed to provide intense education in the foundations of the aeronautical and space sciences, with emphasis on research and analytical, computational, and experimental methods. Entering graduate students should have a thorough background in undergraduate mathematics, physics, and engineering science. In working toward a degree in aerospace, a student may pursue major study in one of the following areas: physics of fluids, physics of i centures, pursis of solids and mechanics of materials, structural mechanics, space technology, computational solid mechanics, computational and theoretical fluid dynamics, aeronautical engineering and propulsion, biomechanics of fluids and solids, technical fluid mechanics, control of aerospace systems and materials. While research and course work in the aerospace option at the Institute cover a very broad range of subjects, a choice of one of the above fields allows students to focus their activities while taking advantage of the flexibility offered by the breadth of interests of the Graduate aerospace Laboratories (GALCIT). In consultation with his or her adviser, a student will design a program of study in one of the above fields, consisting of the fundamental courses described in the regulations for the separate degrees listed below, and of electives selected from the list of Special Regulations for Graduate Options 389 390 aerospace-related courses. This will ensure that the graduating student will be well-qualified for a career in aerospace and related fields. Examinations, Committees, and Student Responsibilities To help students achieve satisfactory progress in their academic pursuits, the aerospace faculty provides for the following committee and individual support. Upon beginning the first year of the aerospace program, each student is assigned a faculty (course) adviser whose research field matches the interests of the student as described in the student's statement of purpose in his or her admissions application. The first-year adviser will guide the student in choosing a set of courses appropriate to the students' interests while ensuring the first-year academic requirements (see below) are met. Students wishing to pursue studies leading to the Ph.D. must select and be accepted by a research adviser by the end of the spring term of the first year of residence and are required to pass a qualifying examination in the first term of the second year. Having passed the qualifying examination, the student pursues research under the supervision of the research adviser until they are ready to enter candidacy for the Ph.D. At this point, a four-member Candidacy Examination Committee that includes the student's research adviser is assembled and administers a Candidacy Examination to ensure the student has the appropriate knowledge and tools to successfully complete his or her chosen research activities. The Candidacy Committee is chaired by a faculty member other than the research adviser. The Candidacy Examination should be administered by the start of the second term of the third year of residence, but in any case, must be successfully completed by the end of that year in order to comply with Institute requirements. Conferral of the Ph.D. degree is contingent on satisfactorily passing the thesis examination before a committee consisting of four examiners, which may, but does not need to, have the same membership as the Candidacy Committee. Students may find further information concerning special option requirements and the requisite option forms on the GALCIT website. AE Master's Degrees Master's Degree in Aeronautics and Master's Degree in Space The master's degree program in aeronautics or space engineering is a one-year program that provides advanced training in the areas of aeronautics or space engineering beyond that covered in a four-year undergraduate program. The program consists of a set of five core courses (see details below). There is no research requirement, nor is a thesis required to obtain the degree. The courses required for the master's degree must be completed in one year. Information for Graduate Students Admission Students whose highest qualification is a baccalaureate degree equivalent to that given by the Institute are eligible to seek admission to work toward the master's degree. Students are asked to submit course transcripts and letters of recommendation as well as evidence of English language proficiency as detailed in the graduate application. Submission of GRE exam scores is optional for the 2022 admissions process in aerospace. It should be noted that the graduate program at GALCIT is primarily focused on Ph.D.-level research and so priority in admission is given to those who plan to ultimately perform Ph.D.-level research. Course Requirements A program of study consists of courses totaling at least 135 units; of these, at least 81 units must be chosen from one of the following curricular tracks: Aeronautics track Two 27-unit course sequences chosen from: • Fluid mechanics (Ae/APh/CE/ME 101 abc) • Solid/structural mechanics (Ae/AM/CE/ME 102abc) • Autonomy and control (CDS 131 or Ae103a in first term, Ae 103b in second term, and a third course selected from department list in coordination with first-year adviser), 27 units Experimental methods (Ae 104abc), 27 units. Space Engineering track Two 27-unit course sequences chosen from: • Fluid mechanics (Ae/APh/CE/ME 101 abc) • Solid/structural mechanics (Ae/AM/CE/ME 102abc) Autonomy and control (CDS 131 or Ae103a in first term, Ae 103b in second term, and a third course selected from department list in coordination with first-year adviser), 27 units Space engineering (Ae 105abc), 27 units Aerospace students in either the Aeronautics or Space Engineering track are required to enroll in a sequence of mathematics courses totaling 27 units appropriate to the student's chosen track and selected in coordination with their first-year advisers. Examples of appropriate courses include ACM/IDS 104, ACM 100ab, ACM 101ab, etc. Examples of appropriate third courses for the Autonomy and Control sequence include Ae115, CD S232, CDS 242, CDS 244, etc. Finally, all first-year students are required to enroll in aerospace Engineering Seminar (3 units Ae 150abc). A grade of C or higher must be achieved in all the required classes unless they are only offered pass/fail, in which case a pass must be achieved in each class. For both the Aeronautics and Space Engineering master's degrees, the remaining 27 units are elective and are to be chosen from courses at Caltech that support the broader Special Regulations for Graduate Options 391 392 goals of the respective programs, subject to the approval of the student's adviser. Students must have a proposed program of courses approved by their adviser prior to registration for the first term of work toward the degree. Admission to More Advanced Degrees Students who successfully complete the requirements for the master's degree and who wish to pursue the more advanced degree of Doctor of Philosophy (Ph.D.) must file a petition to continue work toward the desired degree. All students working for the Ph.D. degree are expected to register for and attend the advanced seminar (Ae 208 abc) for a period of at least two years. AE Degree of Doctor of Philosophy Admission Students with a baccalaureate degree equivalent to that given by the Institute are eligible to seek admission to work toward the degree of doctor of philosophy (Ph.D.) in aeronautics or space engineering. Students are asked to submit course transcripts and letters of recommendation as well as evidence of English language proficiency as detailed in the graduate application. Submission of GRE exam scores is optional for the 2022 admissions process in aerospace. Course Requirements The course requirements for the first year of the Ph.D. degree are identical to those of the master's degree. Students admitted to graduate study for the Ph.D. degree must complete in their first year a course of study that would qualify them for the master's degree described above. The student may elect to receive the master's degree at the end of their first year after completion of these courses. Research Adviser Students wishing to pursue studies leading to the Ph.D. must select and be accepted by a research adviser preferably by the end of their third quarter but no later than the end of their first year of study and prior to taking the qualifying examination described below. Qualifying Examination After the first year of graduate study, the student must pass a qualifying examination. The objective of the qualifying examination is to determine if the student is properly prepared and qualified to pursue problems typical of Ph.D.-level research by demonstrating fundamental understanding of the first year courses in the topic area of the exam. The exam also evaluates effective oral communication of technical material as a skill that is required for professional development. The exam will cover the following subjects: 1. Aeronautics track. Two areas chosen from: a. Fluid mechanics Information for Graduate Students b. Solid/structural mechanics c. Autonomy and control d. Mathematics 2. Space Engineering track. Two areas chosen from: a. Fluid mechanics b. Solid/structural mechanics c. Autonomy and control d. Mathematics The material covered in these examinations is at the same general level and breadth as covered in the corresponding first-year courses. The examinations are typically offered during one week in the first half of the fall term, in the second year of graduate residence at the Institute. A student is examined orally on all topics. In the event of an unsatisfactory performance, the examining faculty members may permit a repeat examination in the appropriate topics. The repeat examination must be scheduled prior to finals week of the winter term and must be completed before the end of the spring term of the same year. Graduate Teaching Assignment Duties GALCIT provides opportunities to students to improve their teaching and communication skills that are valuable in many contexts. Ph.D. students are required to perform a minimum of 18 term hours of Graduate Teaching Assistant (GTA) duties within the aerospace Department during their terms of residence. GTA duties will be assigned after the first year in residence and will be based on courses a student has completed. Candidacy To be recommended for candidacy for the Ph.D. in aerospace, the applicant must • have satisfactorily completed at least 135 units of graduate work equivalent to the above Master of Science program; • pass, with a grade of C or better, 27 units of graduate-level mathematics courses beyond ACM 95/100, and ACM/IDS 104; • complete (with a grade of C or better, or Pass) at least 45 units of aerospace courses numbered Ae 200 or higher, or Ae/ME 118, Ae/ME 120, EE/Ae 157, Ae 159, Ae/Ge/ME 160 and Ae/CE 165ab, excluding research and seminars; and • complete three units of the advanced seminar Ae 208. A proposed program conforming to the above regulations must be approved by the student's adviser and the option representative prior to add day of the first term of work toward the degree. In addition to fulfilling these course requirements, the applicant must pass a candidacy examination in the third year of residence at the Institute. This exam should be administered by the start of the second quarter of the third year of residency. This examination aims at Special Regulations for Graduate Options 393 394 determining whether the student is successful in integrating formal course work into a mature understanding of fundamental engineering concepts, and at demonstrating his or her professional competence in applying these concepts to the problems being addressed in the course of their Ph.D. research. Minor No minor is required for the Ph.D. degree. Students are, however, encouraged to take advanced courses appropriate to their particular interests or pursue a minor in consultation with their adviser. Foreign Languages The student is encouraged to discuss with his or her adviser the desirability of studying foreign languages, but there is no formal foreign language requirement for the Ph.D. Thesis and Final Examination Prior to graduation, each candidate is required to give a seminar presenting the results of his or her thesis research. For final examination and thesis completion, see also the general degree requirements and the section on Examinations, Committees, and Student Responsibilities regarding aerospace. For a description of the Institute requirements for conferral of a Ph.D. see Degree of Doctor of Philosophy. Subject Minor A student majoring in a field other than aerospace may, with the approval of the option representative, elect aerospace as a subject minor. A minimum of 54 units in subjects acceptable to the aerospace faculty is required. Problem and Grievance Resolution within aerospace Students may pursue several avenues for redress concerning personal and academic problems that may arise during their residency, as outlined by the Student Problem Resolution Process described earlier in the catalog. Should a student not wish to discuss the relevant issues with their adviser, the option representative and/or the director are always available to meet with the student. In addition, two other resources are available, one at the student and one at the faculty level. A student representative is elected annually by the aerospace graduate students at or after the Information Session, which is part of Ae 150. In the event that the student representative has completed his or her Ph.D. studies before the election date and left the Institute, the student organizer for Ae 150 may be his or her replacement. A faculty member chosen by the aerospace faculty to provide support for the students is available for student contact. The names of the current student and faculty support persons are available in the aerospace office. Educational Exchange Program with École Polytechnique An educational exchange program is offered by the aerospace option with École Polytechnique (EP). In this exchange program, students selected for participation from Caltech will enroll for one year at EP. Correspondingly, students selected for the program from EP will enroll Information for Graduate Students for one year at Caltech. To be eligible to participate, aerospace students must have completed one full year of study (for Caltech students this is equivalent to the requirements for the M.S. degree and agree that they will spend one full year at EP. First year (G1) graduate students enrolled in Caltech's doctoral aerospace program will be apprised of the opportunity to participate in an educational exchange program at the master's level at EP. A maximum of two students) will be selected by the aerospace faculty from the pool of students who express interest in this program. Caltech students will follow their first (master's) year at Caltech, and their second year in the second-year master's (M2) program at EP. Caltech students must fulfill the requirements of their first-year program and receive their Caltech M.S. diploma prior to proceeding to EP. Caltech students must register at Caltech during the year spent at École Polytechnique and enroll in the special topics course Ae 240 - Educational exchange at Ecole Polytechnique. This ensures that they maintain their standing as enrolled graduate students at Caltech. It is implied that classes taken at one institution cannot duplicate classes already taken at the other institution. The expectation is that Caltech students will return to Caltech after completing the EP program and continue with their doctoral studies at Caltech. Caltech students should be prepared to take the qualifying exams in the fall term when they return from EP. Caltech students participating in the Caltech/EP educational exchange program will be considered to be on detached duty from Caltech while at EP. A detached duty agreement will be executed for each student that spells out the terms and requirements for the detached duty. APPLIED AND COMPUTATIONAL MATHEMATICS (ACM) Aims and Scope of the Graduate Program Caltech's Computing & Mathematical Sciences department offers an interdisciplinary program of graduate study in applied and computational mathematics leading to the Ph.D. degree. This program is designed to give students a thorough training in fundamental computational and applied mathematics and to develop their research ability in a specific application field. The fields of application include a wide range of areas such as fluid mechanics, materials science, and mathematical biology, engineering applications, image processing, and mathematical finance. The training essential for future careers in applied mathematics in academia, national laboratories, or in industry is provided by completion of the requirements for a Ph.D. degree in applied and computational mathematics. The research areas and interests of the applied and computational mathematics faculty cover a broad spectrum, including nonlinear dynamics, computational biology, numerical analysis and scientific computing, computational and theoretical fluid mechanics, theoretical materials science, multiscale computations and homogenization theory, computational methods for electromagnetics and acoustics, statistics, signal and image processing, probability theory and stochastic analysis, and dynamical systems and geometric Special Regulations for Graduate Options 395 396 mechanics. As reflected by the faculty research activities, there is a strong emphasis on computational methods for solving challenging problems arising from engineering and scientific applications. Reflecting the interdisciplinary nature of the program, several different groups, in addition to the applied and computational mathematics faculty, contribute to the teaching and supervision of research. Students in applied and computational mathematics are expected to combine their basic mathematical studies with deep involvement in some field of application. Basic general courses are listed specifically under applied and computational mathematics, and these are to be supplemented, according to the student's interest, from the whole range of Institute courses in specific areas of physics, biology, engineering, etc. A regular colloquium provides the opportunity for visitors, faculty, and students to discuss current research. Admission Each new graduate student admitted to work for the Ph.D. in applied and computational mathematics is given an informal interview on Thursday or Friday of the week preceding the beginning of instruction for the fall term. The purpose of this interview is to ascertain the preparation of the student and assist them in mapping out a course of study. The work of the student during the first year will usually include some independent reading and/or research. Course Requirements All ACM students are required to take a total of 18 nine-unit courses at the graduate level (or the equivalent of 162 units) during their graduate study at Caltech. Among these 18 courses, the following core courses, typically taken during the student's first year of study, are required: ACM/IDS 101 ab, ACM 105, CMS/ACM/IDS 107, Ma 108 abc ACM/EE 106 ab, CMS 117, and an application elective course. The application elective course in the first year is selected, with the recommendation of the student's adviser, from among a wide range of courses offered by an outside option within the Institute. In addition, CMS 290 is required for all first year ACM graduate students during each term (fall/winter/spring). In the second and third years, students are expected to take graduate-level courses appropriate to their chosen research area. The remaining courses towards the 162 unit requirement would normally include graduate-level ACM or CMS courses such as CMS/ACM/EE 122, ACM 201, 210, ACM/IDS 216, ACM/IDS 217, etc., as deemed appropriate to the student's research program, and which must be selected in consultation with the student's research adviser. Students who have already taken some of the required courses may use them to satisfy the course requirements, even though the units may not be used to satisfy the total unit requirement for the Ph.D. degree. Information for Graduate Students ACM Master's Degree Students are not admitted to work toward the master's degree. The master's degree may be awarded to an ACM student only in exceptional circumstances. Of the 135 units of graduate work required by Institute regulations, at least 81 units of advanced graduate work should be in applied mathematics. ACM Degree of Doctor of Philosophy The Preliminary Examination. Toward the end of the first year, all incoming students must take a preliminary examination administered by the faculty. Its purpose is to ensure a solid and broad knowledge in applied and computational mathematics, and in the event of a deficiency, to direct the students to necessary course and reading. The Candidacy Examination To be recommended for candidacy for the Ph.D. degree in applied and computational mathematics, all students must, in addition to meeting the general Institute requirements and passing the preliminary examination, pass a candidacy examination administered by a committee that consists of at least four faculty, is approved by the option representative, and is chaired by the student's research adviser. The examination will ascertain the student's breadth and depth of preparation for research in the chosen area. The examination must be taken within the first three years of residence. Advising and Thesis Supervision Upon passing the preliminary examination, the student is required to choose a thesis supervisor who assumes the major responsibility in supervising the Ph.D. thesis. At the same time, an advising committee consisting of three faculty members is formed to help oversee the advising process. This committee should be formed no later than the third year of graduate study. The student's supervisor is part of this committee, but does not chair the committee. The student is encouraged to meet with the committee members informally for advice or suggestions. Joint supervision between two faculty members is also possible, as is seeking a thesis adviser outside the core applied and computational mathematics option, although in this case it is mandatory that an applied mathematics faculty member be nominated as a co-adviser. Should a disagreement of any kind occur between the student and his or her supervisor as regards the timely completion of the thesis, the student is encouraged to direct his or her concerns to the committee chair. If this is not workable, the student should feel free to consult with the option representative, the executive officer, or an applied and computational mathematics faculty member of the student's choice. If the student's concerns cannot be resolved through consultation with these individuals, the student is encouraged to pursue resolution of his or her concerns through other channels as outlined in the Student Problem Resolution Process. Special Regulations for Graduate Options 397 398 Final Examination The final oral examination is held within four weeks after the submission of the thesis. The examination covers the thesis and related areas. ACM Subject Minor The group of courses must differ markedly from the major subject of study, and must include 54 units of advanced courses in applied mathematics and must not be simultaneously used for fulfilling a requirement of the second option. The qualifying courses exclude ACM95/100, although some flexibility is allowed depending upon the option of origin. The student must pass an oral examination whose subject is directly related to the material covered in the qualifying courses. This oral examination will be waived if the student has received a grade of A in every course. APPLIED MECHANICS (AM) Aims and Scope of the Graduate Program Applied mechanics (AM) research and study are offered through the Department of Mechanical and Civil Engineering (MCE). The degrees of Doctor of Philosophy (Ph.D.) and Master of Science (M.S.) are offered. In general, students who intend to work full-time toward the Ph.D. degree as a final degree objective are admitted to the Applied Mechanics Graduate Program. The M.S. degree is typically only awarded to students who pursue the Ph.D. degree in applied mechanics at Caltech and who do not already have an M.S. degree in applied mechanics. The aim of the graduate program in applied mechanics at Caltech is to prepare students for research and professional practice in an era of rapidly advancing interdisciplinary technology. The program combines individual depth of experience and competence in a particular chosen major specialty, with a strong background in the basic and engineering sciences. It strives to develop professional independence, creativity, leadership, and the capacity for continuing professional and intellectual growth. AM Preparation for the Graduate Program Entering graduate students are expected to have a thorough background in undergraduate mathematics, physics, and engineering. While a strong undergraduate program in applied mechanics should provide a suitable preparation, students who have not specialized in applied mechanics as undergraduates may also be admitted for graduate study. For example, an outstanding four-year undergraduate program in mathematics and sciences may provide a suitable background as well. The qualifications of each applicant will be considered individually, and, after being enrolled, the student will arrange their program in consultation with a member of the faculty. Information for Graduate Students AM Master's Degree The degree of Master of Science in applied mechanics is only awarded to students who do not already have an M.S. degree in applied mechanics. The degree will be awarded upon request by students who have fulfilled the requirements. Only in exceptional cases is there admission to the M.S. program as the final degree objective. A minimum of 138 units of courses numbered 100 or above, which meet the required master's program listed below, must be passed with a grade of at least C for completion of the master's degree in applied mechanics. All units must be taken for grades, except for courses offered only on a pass/fail basis. The M.S. degree in applied mechanics is typically completed within the first two years of residency at Caltech. Each student's program must be approved by the adviser and option representative in mechanical and civil engineering before registering for the course. Required Master's Program 1. Graduate applied mechanics core (45 units). These units should provide a solid base for the student's engineering interest.

AM Degree of Doctor of Philosophy The Ph.D. degree in applied mechanics is focused on research. Study and research programs for the Ph.D. degree are individually planned to fit the interests and background of the student. A comprehensive research project resulting in an original contribution to the field, which is documented by a thesis, is required. Institute requirements for the Ph.D. degree are described in the section on degree requirements. A minimum of three academic years in residence as a graduate student are required by the Institute, and two or more additional years are usually needed for preparation of the thesis. Advising and Thesis Supervision An interim adviser is appointed for each student upon admission to a graduate degree in applied mechanics. The interim adviser will serve as the primary mentor until the student finds a research adviser. It is the responsibility of the student to find an academic and research adviser within three terms of graduate residence at Caltech. In consultation with the adviser, the student must form a Ph.D. Thesis Advisory Committee within four terms of graduate residence at Caltech. This committee shall consist of at least three members of the Special Regulations for Graduate Options 399 400 Caltech professorial faculty, with at least two members from the faculty in mechanical and civil engineering. The committee shall meet as requested by the student.

Registration Beyond the Sixth Year of Graduate Residence The annual approval of the Ph.D. Thesis Advisory Committee is necessary for registration beyond the twenty-fourth academic term of graduate residence at Caltech. Thesis and Final Examination The thesis examination will be given after the thesis has been formally completed. This examination will be a defense of the doctoral thesis and a test of the candidate's knowledge in the specialized field of research. The format of the examination can be chosen from the following two options, by the student, in consultation with the students research adviser: (i) a public seminar presented by the candidate, with an open question period, followed by a private examination by the Examining Committee or (ii) a private presentation to the Examining Committee followed by the examination, with a public seminar on another date. The Examining Committee shall consist of a minimum of four voting members, three of whom must be Caltech faculty; two members must be from MCE. The Thesis Defense Committee shall be chaired by a committee member who is an MCE Caltech professorial faculty member and not the student's adviser. Special Regulations for Graduate Options 401 402 AM Subject Minor A student majoring in another branch of engineering or another division of the Institute may, with the approval of the faculty in the Department of Mechanical and Civil Engineering and the faculty in the students major field, elect applied mechanics as a subject minor. The program of courses must differ markedly from the major subject of study or research, and must consist of at least 54 units of advanced courses (101 or above) approved by the faculty in mechanical and civil engineering. APPLIED PHYSICS (APH) Aims and Scope of the Graduate Program Applied physics is a broad field of study that lies at the intersection of physics and many other fields of science and engineering. The applied physics option at Caltech is accordingly a highly multidisciplinary program that is designed to train students in a broad spectrum of physics and engineering fields at an advanced level. Moreover, it is our goal to cultivate abilities in our graduates to apply this knowledge throughout their lives so as to make technological and scientific breakthroughs at the edge of current knowledge. APh Preparation for the Graduate Program Students admitted for graduate study can enter from a broad range of disciplines, but are expected to have a rigorous background in undergraduate mathematics, physics, and engineering. An outstanding four-year undergraduate program in mathematics and sciences may provide a suitable background as well. The qualifications of each applicant will be considered individually. After enrollment, the student will arrange a course of study and research in consultation with members of the faculty and the applied physics option representative. APh Description of the Degree of Doctor of Philosophy (Ph.D.) To receive the doctoral degree in applied physics students must demonstrate the ability to formulate and execute an original program of scientific study. As part of this, a doctoral candidate is expected to develop a deep understanding in a chosen field of specialization; to develop tools with which to assess problems outside one's field of specialization; to develop rigor and strength in the physical sciences for self-education beyond formal training; and to develop skills to become a productive member of the community of scholars. All students wishing to enter the program must complete a series of preparatory courses, followed by an oral candidacy exam in which the student describes their proposed topic of research and is examined on their knowledge of course subject matter. Upon passing the candidacy examination, students work towards completion of a thesis in consultation with their research adviser. The doctoral degree is awarded upon approval of a written thesis by a faculty committee, and successful defense of the thesis in a final oral examination. There is no separate master's program in applied physics. However, with the Information for Graduate Students approval of the student's adviser and the applied physics option representative, the degree of Master of Science in Applied Physics may be awarded after the fulfillment of the course requirements described below. APh Advising and Thesis Supervision An interim adviser is appointed for each student upon admission to the graduate program in applied physics. Typically, this person is the applied physics option representative. In consultation with the interim adviser the student will determine a course schedule and identify a faculty research adviser. This most often occurs within the first six months of graduate residence. The faculty adviser is the student's primary mentor and the student will work in the adviser's research group to formulate and execute a plan of study leading to the thesis. In consultation with their research adviser, the student will also form a Ph.D. Thesis Advisory Committee. This four-member committee should include the student's adviser and at least three members of the Caltech professorial faculty from either the applied physics or physics options. The Thesis Advisory Committee will conduct the qualifying examination and also approve the thesis and conduct the thesis defense. The membership of this committee may change between the time of the qualifying exam and the final defense. APh Requirements for Candidacy to the Ph.D. Degree To be recommended for candidacy for the Ph.D. degree in applied physics, a student must demonstrate mastery in the following five areas of pure and applied physics: • Classical Physics: Mechanics and Electromagnetism • Quantum Mechanics • Mathematical Methods • Statistical Physics and Thermodynamics Biophysics, Optical Physics, Hydrodynamics, Plasma Physics, or Solid-State Physics A. Graduate Coursework toward Candidacy In partial fulfillment of the "mastery" requirement a student must successfully complete a minimum of 108 units of courses numbered 101 or above from the course schedule. In addition, 4 units of APh 110ab must also be completed. All courses must be passed with a grade of at least a C, except for courses offered only on a pass/fail basis. Students must also complete the degree progress report online upon completion of their courses. Note: Any given class can only be used for one requirement category. Total Units 1.

Total Units Applied Physics Research APh 200 27 Students entering the program with advanced preparation may choose either to substitute more advanced courses in the topical areas shown or demonstrate competency by successfully passing both the midterm and final examinations. In such cases, students may petition the Applied Physics option representative to accept alternate subjects or areas. These changes should retain core applied physics knowledge, and maintain sufficient breadth. All such petitions must be submitted to the option representative and approved before the student registers for the course. Coursework towards the Ph.D. degree in Applied Physics is normally completed within the first two years of graduate residency. B. Candidacy Examination To fulfill the requirements for candidacy all students must pass an oral examination after completing their coursework. This examination must be taken before the beginning of the student's third year in residence. Students will be expected to deliver a half-hour oral presentation giving a prospectus on their proposed thesis research. Following questions on the research prospectus, a more open-ended set of questions will be posed to the student by the committee members to test general proficiency in the five areas of pure and applied physics listed above. Students who fail the oral examination on their first attempt will be given additional guidelines for further study and an opportunity to retake the examination a second and final time if the committee so recommends. Students who fail the oral examination a second time cannot continue with doctoral studies leading to the Ph.D. Upon recommendation of the examining committee, however, a student may be granted a master's degree. Annual approval of the applied physics option representative is necessary for registration beyond the third year of graduate residence if the student has not completed the candidacy examination. Special Regulations for Graduate Options 405 406 Students who fulfill the requirements above will be recommended for candidacy to the doctoral program and a master's degree (if applicable) in applied physics. APh Ph.D. Thesis Requirements The candidate is to provide a draft copy of the completed thesis to the members of the examining committee (typically the same as the thesis committee) at least two weeks before the final oral examination. The date of the examination and the composition of the examining committee will not be approved by the dean of graduate studies until the thesis is submitted in completed form, i.e., ready for review by the dean, the members of the thesis committee, and the Graduate Office proofreader. Registration is required for the term in which the thesis defense is taken, but is not normally allowed beyond the last date of the term. For more information, please see the section entitled "Information for Graduate Students" in the Caltech Catalog. APh Ph.D. Final Examination The candidate shall undergo a final broad oral examination (thesis defense) in the field, to include the subspecialty represented by the thesis and the significance of its findings to the field. This oral examination will be administered at least two weeks after the doctoral thesis has been presented in final form so that the examining committee has sufficient time to review its content. This examination must be taken at least three weeks prior to the date on which the degree will be officially conferred. APh Registration Beyond the Sixth Year of Graduate Residence The annual approval of the student's Thesis Advisory Committee is necessary for registration beyond the twenty-fourth academic term of graduate residence at Caltech. APh Subject Minor Graduate students majoring in other fields may elect a minor in applied physics. In addition to general Institute requirements, the student must complete, with a grade of C or higher, 81 units of courses in applied physics above the 100 level, excluding APh 200. The minor is also subject to the following conditions: • Students cannot use courses required by their major option in fulfillment of this requirement. • Students interested in a minor must receive prior approval from the option representative in applied physics, who will review and approve the proposed course of study. • It is recommended that this course of study include advanced courses spanning different subfields of applied physics. Information for Graduate Students ASTROPHYSICS (AY) Aims and Scope of the Graduate Program The primary aim of the graduate astrophysics program at Caltech is to prepare students for creative and productive careers in astrophysical research and a variety of other challenging vocations. The astrophysics program emphasizes independent research by graduate students, who are free to pursue study in virtually any area of astrophysics. The opportunity exists to take advantage of the many observational facilities owned and operated by Caltech. Ay Admission Incoming students should have a strong background in physics, and although a good preparation in astronomy is helpful, this is not required for admission to the graduate program. The GRE tests (general and advanced subject) are not required and scores will not be considered for admission. Ay Master's Degree While the option does not offer a master's degree program in itself, students who fulfill the general Institute requirements for such a degree, and the specific option requirements (see below), can receive a master's degree, either en route to a final Ph.D. degree if admitted to candidacy, or as a terminal degree if the Ph.D. requirements are not met. The choice of astronomy and other science elective courses must be approved by the option representative. At least 54 units of the 135 units must be selected from Ay 121-127, with at least 36 units earned with a grade of B- or better. The courses Ph 106, Ph 125, and Ph 129 may be required of those students whose previous training in some of these subjects proves to be insufficient. At least 27 units of advanced courses in fields other than astronomy are required. Ay Degree of Doctor of Philosophy Astrophysics Program The student's proposed overall program of study must be approved by the option representative during the first year. The following are required of all students for candidacy: Ay 121, Ay 123, Ay 124, Ay 125, Ay 126, and Ay 127. The student should take these courses in the first year. Students must also take at least one term of Ay 122 unless exempted. Also required are research and reading projects. Credit for this work will be given under Ay 142 and Ay 143. The above courses must be passed with a grade of B- or better. Electives Program The first two years of graduate study should include at least four courses (36 units) of additional electives relevant to astrophysics, with six courses (54 units) required of theory students. The electives requirement may be reduced for students who need to take Ph 106, Ph 125 or Ph 129 in order to make up for gaps in preparation at the undergraduate level. Special Regulations for Graduate Options 407 408 Suggested elective courses include, but are not limited to: Ph 101, Ph 105, Ph/Aph 118 a, Ph 127 b, Ph 135, Ph 136ab, Ph 236, Ph 237. For theory students, Ph 136 a and Ph 136 b are required, and in addition to Ph, electives in applied mathematics should be considered. For students in observation and experiment, Ph 136 a and Ph 136 b are strongly recommended, and in any case at least one of the four advanced course electives must be in Ph, while the complement may be from other options such as electrical engineering, applied mechanics, computer science, planetary science (geophysics or geochemistry). Seminar courses and research practicum courses do not count as satisfying the requirement for pedagogical elective coursework; however, students are encouraged to take these types of courses during second year. No more than 18 of the elective units may be taken P/F; all others must be passed with a grade of C or better. In the third year and above, students are welcome to enroll in additional advanced astronomy and physics courses. Other Requirements Each term the student must be registered for at least 36 academic units, with additional electives such as from PA/PE/HSS allowed on top of the 36. An ability to explain concepts and to verbally present one's work is vital to a successful career in research and/or teaching. To this end, all graduate students inFAeroastrophysics are required to serve as teaching assistants during their second year, and to make oral presentations as part of the course Ay 141, 3 terms of which must be taken every year by all students beginning in their second year. Graduate students for whom English is a second language may be required to demonstrate fluency in oral and written English at the time of their candidacy exam. The examining committee will arrange for an evaluation if this is deemed necessary. Admission to Candidacy To be recommended for candidacy for the Ph.D. degree in astrophysics, a student must, in addition to meeting the general Institute requirements: • complete satisfactorily 36 units of research (Ay 142) or reading (Ay 143); • pass satisfactorily, or by special examination, the required astrophysics courses (see above); • pass a general oral examination (see below); • pass a thesis-related examination (see below); • complete the physics course requirement (see above); • satisfy a teaching requirement (generally two terms as a GTA); • fulfill the language requirement if applicable (see above); and • be accepted for thesis research by a member of the faculty. In fall of their second year, all students are required to take a general oral qualifying examination. Students will be examined on the substance and status of, as well as their performance on, a research project, which should be started not later than the summer following Information for Graduate Students the first year. They will further be examined on their broad understanding of current topics in, and fundamentals of, astrophysics. Both of these aspects of the examination are intended to evaluate the candidate's aptitude for a research career in astrophysics. In addition, at the discretion of the executive officer, students who have not done well in one, or at most two, areas covered in the Ay 12x course series during their first year will be retested in these areas during the examination. Students must pass all of the aspects of this examination, as judged by the faculty committee conducting it, in order to continue in the Ph.D. program. Students who do not meet the minimum grade requirements in the Ay 121-127 series, or who do not pass the general candidacy examination described above, will not be able to continue in the Ph.D. program. They may receive a terminal master's degree, provided that they fulfill the requirements for it (see above). Advising and Thesis Supervision By the summer of their first year, students should be spending most of their time on research. During their first two years, students are free to work with any faculty they wish, on one or more projects. However, by the summer of their second year at the latest, they should have defined a thesis project and been accepted by a faculty research adviser for that project (in cases where the thesis involves multiple projects, a second faculty adviser may supervise part of the research, but one must be selected as primary adviser). An oral candidacy exam dealing with the student's proposed thesis research should be completed before the end of the third year. The date and time of the exam are the responsibility of the student to arrange. The candidacy committee is approved by the option representative in consultation with the student's adviser and a list of suggested members provided by the student. This committee becomes the student's Thesis Advisory Committee (TAC) and will stand until the final oral thesis defense, and be charged with ensuring that satisfactory progress toward the Ph.D. is being made. If the candidate does not pass the oral candidacy exam, then the candidacy committee may at its discretion offer the candidate a second oral examination. This examination must be successfully completed by the end of the third term of the third year. After the oral candidacy exam, the adviser and the student together have primary responsibility for the student's progress and career development. To ensure that these remain on course, both student and adviser must submit annual progress reports to the executive officer (or in the case of a conflict of interest, to the astrophysics option representative or the division chair), and meet ("check-in") with the committee members at least once per year. If at any stage the student, the adviser, or the executive officer feels that there are serious problems developing, they may consult in confidence with the astrophysics option representative, the executive officer, or the division chair. They may also request a meeting of the committee or seek the advice or help of other faculty members. Students may also consult with the PMA director of student programming or seek Special Regulations for Graduate Options 409 410 confidential advice and help from the Student Wellness Services. Final Examination (Ph.D. Oral Thesis Defense) A final draft of the thesis must be submitted to the registrar at least six weeks before the commencement at which the degree is to be conferred. At least two weeks after submission of the thesis, the student will be examined orally on the scope of the thesis and its relation to current research in astrophysics. The examination will be conducted by a committee selected in the same way as thecandidacy committee and is nominally the thesis advisory committee. The oral thesis defense should occur before the end of the fifth year. Typical Timeline Year 1: Ay 121, Ay 123-127; at least two advanced physics courses; reading and independent study. Begin research. Year 2: Early fall- general oral qualifying examination. Fulfill teaching requirement.

Ay Subject Minor The program for a subject minor in astrophysics must be approved by the option representative in both options before admission to candidacy in the home option. In addition to general Institute requirements, the student pursuing a graduate subject minor in astronomy must complete with a grade of C or better, 45 units in advanced courses in astronomy. BIOCHEMISTRY AND MOLECULAR BIOPHYSICS (BMB) Aims and Scope of the Graduate Program An integrated approach to graduate study in biochemistry and molecular biophysics has been organized primarily by the Divisions of Biology and Biological Engineering (BBE) and Chemistry and Chemical Engineering (CCE). The curriculum is designed to provide a broad background in biochemistry and biophysics of macromolecules and molecular assemblies, in addition to an appropriate depth of knowledge in the field selected for the Ph.D. thesis research. BMB Admission The option in Biochemistry and Molecular Biophysics is open to students with undergraduate degrees in biochemistry, biology, chemistry, biophysics, physics, engineering, and related areas. Applicants whose native language is not English may submit results of the TOEFL exam and, after admission, are required to satisfy the Information for Graduate Students English language requirements of the Institute. BMB Master's Degree Students are not admitted to work toward the M.S. degree. A terminal M.S. degree may be awarded only in special circumstances. In addition to meeting Institute requirements, a student must have formed a committee of four Caltech faculty, typically the Ph.D. candidacy committee, who must approve the request to obtain a M.S. in consultation with the Option Representative, typically conferred after the end of the second year of residence. BMB Degree of Doctor of Philosophy The option eepresentative will counsel and oversee the student's progress upon admission to the graduate program. During the first year of graduate study, students are required to participate in the BMB 202 seminar course and BMB 174. Additionally, as noted below, the option offers a series of courses that will expose the student to contemporary issues in biochemistry and molecular biophysics, and to the tools and methods that are essential for research in this area. Research advisers are normally selected at the end of spring quarter of the first year. Students are required to take five additional advanced courses of nine or more units for grades that are appropriate for their research interests (as determined by the option representative). Teaching All students are to serve as teaching assistants for two quarters with the first in the first year of residence and the second by the end of the fourth year. In addition to serving an educational purpose, funds for the TA assignments are a component of the stipend. Outside factors, such as previous TA positions prior to starting the Ph.D. program, may be considered as satisfying the requirement upon approval by the option representative. Laboratory Rotations In consultation with the Option Representative and individual professors, students will choose three laboratories to do one term research projects during their first year of residence. These laboratory rotations are designed to provide students with an introduction to different areas of biochemistry and molecular biophysics along with identifying a lab for thesis research. It is possible to waive the third rotation with permission given by petitioning the Option Representative. Admission to Candidacy By the end of the sixth term of residency, the student will take an oral examination to assess mastery of the field of biochemistry and to evaluate research progress. As part of this examination, each student will submit a written research report summarizing the progress in their research, and an original research proposal in a field outside the student's chosen field of research. A candidacy examination committee of four to five faculty (including the advisor) will be assembled by the student in consultation with their advisor and Special Regulations for Graduate Options 411 412 approved by the Option Representative. The chair of the committee should be identified at the time the committee is chosen and must be a member of the BMB option who is not the thesis advisor. In addition to satisfactory completion of the Candidacy exam, admission to Candidacy requires satisfactory completion of BMB 174 and five additional advanced courses of nine or more units (numbered 100 or above). Upon admission to candidacy, the faculty committee will become the thesis advisory committee. Students are required to meet annually with their thesis advisory committee to evaluate research progress. This committee will also serve as the Ph.D. thesis examination committee. A fifth member may be added at this time. After Candidacy, a student will meet annually with the thesis committee to assess progress. Thesis and Final Examination Thesis research will be carried out under the direction of one or more faculty members in the BMB option. The thesis defense will consist of a public thesis seminar, followed by a closed examination by the Ph.D. thesis committee. BIOENGINEERING (BE) Aims and Scope of the Graduate Program Bioengineering research at Caltech focuses on the application of engineering principles to the design, analysis, construction, and manipulation of biological systems, and on the discovery and application of new engineering principles inspired by the properties of biological systems. Areas of research emphasis include: biodevices, bioimaging, bioinspired design, biomechanics, biomedical engineering, cell and tissue engineering, molecular programming, synthetic biology, and systems biology. The goal of the doctoral program is to prepare students to become leading scientists and engineers in academia and industry. The graduate program aims to educate students to be highly competent in their chosen area of research, but also provide them with a broad knowledge foundation in bioengineering. By graduation, students are expected to have a working knowledge of bioengineering in general and an in-depth knowledge of their chosen area, have independently planned and conducted research experiments in their chosen area, and successfully defended their thesis work in an open forum. BE Master's Degree Students are not admitted to work toward the M.S. degree. In special circumstances, the M.S. degree may be awarded, provided Institute requirements are met. Information for Graduate Students BE Degree of Doctor of Philosophy In addition to satisfying the general Institute requirements, candidates for a Ph.D. in bioengineering at Caltech must satisfy the following requirements: Course Requirements Coursework requirements provide maximum flexibility in building on undergraduate training and complementing the research activities of each student. To assist in the selection of a research area, to foster interactions within the entering class, and to discuss ethical guidelines for scientific research, students participate in three required discussion courses in their first year: current research topics in Caltech bioengineering labs (BE 267, first term); Reading the Bioengineering Literature (BE 201, second term); Responsible Conduct of Research (Bi 252, first term). Graduate students must take BE 201 again in their second year. In addition to the required courses, students must take at least six electives (one-quarter courses totaling at least 54 units; grade of B or higher in each course) selected in consultation with the student's adviser and the option representative. Two of these courses must be Bi/CNS/NB 195 and BE/Bi 103 a, unless the option representative deems the student's past course work to have covered the topics of those courses and waives the requirement. Waived courses do not count toward the requirement of six electives. To maximize the opportunity for research during the early stages of the graduate career, coursework may be spread over the first and second years. Electives are listed below. Other courses may count as electives at the discretion of the option representative. Bioimaging and biomedical devices electives: AM/CE 151 ab, APh 109, APh/EE 130, APh/EE 132, BE/EE/MedE 189 ab, Bi/BE 177, Bi/BE 227, EE/APh 131, EE/BE/MedE 185, EE/MedE 187, Ph 106 abc, Ph/APh/EE/BE 118 abc.

Special Regulations for Graduate Options 413 414 Research The flexibility of the coursework requirements enables research to be the primary activity from the very first term in residence. Students are encouraged to do two or more research rotations during the first year to sample research activities in multiple labs before selecting a Ph.D. adviser. Rotations are arranged by contacting individual faculty. Adviser Selection Each student must select a Ph.D. adviser by the end of the spring term of the first academic year. Advisers may be any Caltech faculty member working in an area related to bioengineering. First Year Conversation Before the end of the spring term of the first year in residence, each student meets with a faculty committee for a discussion of first-year progress and second-year plans. The committee must be composed of three faculty, plus the Ph.D. advisers), including a minimum of two bioengineering faculty. The student will give a brief presentation on research progress and future plans, as well as discuss fundamentals related to the research area. Admission to Candidacy By the end of the spring term of the second year in residence, each student must complete the coursework requirement, prepare a candidacy report, and pass an oral candidacy exam. The report should be brief, describing research progress to date and outlining plans for the remaining doctoral research. The candidacy report should be submitted to the committee members one week before the oral exam. The committee must be composed of three faculty, plus the advisers), including a minimum of two bioengineering faculty. The oral candidacy exam will include presentation of research progress, presentation of a proposed outline for the thesis, and questioning on fundamentals related to the research area. Students who complete the coursework requirement, prepare a candidacy report, and pass the oral candidacy exam will be recommended for candidacy. Students who are not admitted to candidacy by the end of the second year in residence will not be permitted to register in subsequent terms except with special permission from the option representative. Thesis Advisory Committee Meetings Following admission to candidacy, the doctoral student will select a Thesis Advisory Committee (TAC). The committee must be composed of three faculty, plus the advisers), including a minimum of two bioengineering faculty. This committee should meet at least once each year for the remainder of the student's time at Caltech. Thesis Examination A final oral examination will be given after the thesis has been formally completed. The exam will consist of a public research presentation followed by a private defense with an exam committee. The committee must be composed of three faculty, plus the advisers), including a minimum of two Bioengineering faculty. The thesis examination will be Information for Graduate Students a defense of the doctoral thesis and a test of the candidate's knowledge in his or her specialized field of research BE Subject Minor A student may, with the approval of the bioengineering graduate option representative, elect a subject minor in bioengineering. Such a program shall consist of 45 units of upper division course work in bioengineering, with each course passed with a grade of C or better. Courses used to satisfy course requirements in the student's major option may not be used to satisfy the minor requirements. Approval of each program must be obtained from the bioengineering graduate option representative. BIOLOGY (BI) Aims and Scope of the Graduate Program Graduate students in biology come with very diverse undergraduate preparation -majors in physics, chemistry, mathematics, or psychology, as well as in biology and its various branches. The aims of the graduate program are to provide, for each student, individual depth of experience and competence in a particular chosen major specialty; perception of the nature and logic of biology as a whole; sufficient strength in basic science to allow continued self-education after formal training has been completed and thus to keep in the forefront of changing fields; and the motivation to serve his or her field productively through a long career. In accordance with these aims, the graduate study program in biology includes the following parts: (a) the major program, which is to provide the student with early and intense original research experience in a self-selected subject of biology, supplemented with advanced course work and independent study in this subject; and (b) a program of course work designed to provide well-rounded and integrated training in biology and the appropriate basic sciences, which is adjusted to special interests and needs. An individual program will be recommended to each student in a meeting with the student's advisory committee (see below). The Division of Biology and Biological Engineering does not encourage applications from students who have pursued undergraduate study in biology at the Institute, because the broader perspective to be gained from graduate study in a different setting is considered to be essential for the full development of each student's potential. Exceptions to this policy may be considered by the faculty of the division if there are circumstances that indicate that it would be in the best interests of a student to pursue graduate study at the Institute. Bi Admission Applicants are expected to meet the following minimal requirements: mathematics through calculus, general physics, organic chemistry, physical chemistry (or the equivalent), and elementary biology. Students with deficient preparation in one or more of these categories may be admitted but required to remedy their deficiencies in the first Special Regulations for Graduate Options 415 416 years of graduate training, with no graduate credit being granted for such remedial study. Bi Master's Degree The Biology option does not admit students for work toward the M.S. degree. In special circumstances the M.S. degree may be awarded, provided Institute requirements are met. In general, the degree is not conferred until the end of the second year of residence. The degree does not designate any of the disciplines of the division, but is an M.S. in Biology. The 135 units required by the Institute must include Bi 252 and any two courses from the series Bi 250 abcd. Bi Degree of Doctor of Philosophy Major Subjects of Specialization A student may pursue major work leading to the doctoral degree in any of the following subjects: biophysics, cellular biology, developmental biology, genetics, immunology, microbiology, molecular biology and biochemistry, and systems biology. At graduation, a student may choose whether the degree is to be awarded in biology or in the selected major subject. Students who choose to work in neurobiology may also qualify for a Ph.D. in Biology but are encouraged to enroll in the Neurobiology option. Initial Advisory Meeting At the start of the first year of study, incoming students meet with the option representative or faculty members) specified by the option representative. The purpose of this meeting is to assist the student in organizing laboratory rotations, and to discuss what additional course work is desirable in light of the student's past record. Rotations The major initial responsibility of each student is to explore the various research possibilities available at Caltech before settling into a laboratory for their thesis research. Students are free to rotate in any laboratory at Caltech, not just those in the Division of Biology and Biological Engineering. First-year students should carry out a minimum of two laboratory rotations; three rotations are recommended. It is generally expected that rotations will last a full academic quarter; however, exceptions can be granted with the advance permission of the professor. Choice of laboratory should be made by the end of June of the first year except in extraordinary circumstances. Any exception should be discussed with the option representative. Formal Classes During the first year of graduate studies, students are required to take Responsible Conduct of Research (Bi 252) and at least two courses from the series Bi 250 abcd that covers the breadth of fields represented in biology at Caltech. During each year that they are matriculated in the Ph.D. program, students are required to take Bi 251 abc (Biolunch). Students will be required to present their thesis research in Biolunch during their second and fourth years of study. In Information for Graduate Students addition to these fixed requirements, during their time at Caltech students must take three additional 100-series or 200-series courses (9 or more units each; grade of B or higher in each course), at least one of which must focus on mathematical or statistical methods relevant to biology. Teaching All students are to serve as teaching assistants for one quarter per year they are in residence, up through the third year. Admission to Candidacy During winter quarter of the second year, a student is to set up a thesis proposal examining committee and prepare a proposal focused on the research project that they expect to pursue for their thesis research. The proposal is defended by the student in an oral presentation in front of the thesis proposal examining committee by the end of June. (Although it is anticipated that this exam will be completed by June of the second year, it can be delayed until August of the third year if the option representative agrees.) The examining committee comprises four faculty members, at least three of whom should hold full or joint professorial appointments in the Division of Biology and Biological Engineering. One of the members of the committee is appointed as chair. The chair of the thesis examining committee must be a Caltech faculty member other than the student's adviser. The adviser can, but need not be, a member of the examining committee. The members of the thesis proposal examining committee must certify passage of this exam. In the event that there is inadequate evidence of the capacity to do research, the student may be allowed to petition to re-take the oral exam at a later time. However, in cases where the committee deems it unlikely that the student will be able to pass a subsequent attempt, the student may be advised to leave the program. In any event, a student cannot remain in the program beyond August of the third year without having successfully completed the requirements for admission to candidacy, except in extraordinary circumstances and with the approval of the option representative and the dean of graduate studies Thesis Advisory Committee Meetings Once a student has been formally admitted to candidacy, they are to pick a Thesis Advisory Committee (TAC). This committee is often the same as the thesis proposal exam committee, but that need not be the case. The thesis adviser must be a member of the TAC. The TAC typically has four members. At least three must be professorial faculty who hold a full or joint appointment in the Division of Biology and Biological Engineering. It is expected that students who have been admitted to candidacy will meet with the TAC once a year for the remainder of their time at Caltech. Students who fail to meet with their TAC in any one year may be deemed to not be maintaining satisfactory progress toward the Ph.D. degree and will be prevented from registering for the subsequent academic year. Special Regulations for Graduate Options 417 418 Maintaining Satisfactory Progress It is the policy of the Biology option that a graduate student who is making satisfactory progress toward a Ph.D. degree can expect to continue as a registered student with full financial support. To be deemed as making satisfactory progress, a student is expected to fulfill the expectations listed below. In the event that satisfactory progress is not being made, a student can petition to receive the M.S. degree, for which they must have successfully completed one full year of graduate study. Requirements for satisfactory progress include: • Completion of the first-year course requirements during the first year. • Joining a laboratory in which a student will perform thesis research before the end of the first year in residence. • Passing the qualifying examination and completing admission to candidacy before the start of the fourth year in residence. • Holding a Thesis Advisory Committee meeting in each subsequent year of studies, and having the thesis committee verity that satistactory progress is being made. • Serving as a teaching assistant for one quarter of each academic year spent in residence through third year. • Completing Ph.D. studies by the end of the sixth year In the event that the student, option representative, and adviser are in agreement, it is possible to make exceptions to the above guidelines and remain in good standing. Extension of thesis work beyond twenty-four terms requires that the student petition the dean of graduate studies for permission to register. Extensions beyond the seventh year will be allowed only in unusual circumstances. Once a student has passed admission to candidacy, the responsibility for assessing satisfactory progress lies largely with the student's Thesis Advisory Committee. If a majority of the committee deems that a student is not making satisfactory progress, the student is at risk of being removed from the program at any time at the discretion of the option representative. Examination Committee Requirements for the Ph.D. thesis and examination are determined by the Ph.D. examination committee that is appointed by the dean of graduate studies for each degree candidate. This committee is usually the same as the Thesis Advisory Committee, but this need not be the case. The composition of the committee must be approved by the option representative. The committee usually has four members. At least three must be professorial faculty who hold a full or joint appointment in the Division of Biology and Biological Engineering. Information for Graduate Students Thesis and Final Examination The thesis and associated publications are expected to demonstrate that the student has learned how to conceive, plan, and execute experimental and/or theoretical work that reveals new biological information. In addition, it must reveal a deep, broad, and rigorous understanding of the area of research to which the thesis is relevant. Two weeks after copies of the thesis are provided to the examining committee, division chair, and option representative, the candidate collects the copies and comments for correction. At this time, the date for the final examination is set at the discretion of the thesis advisor and the division chair. The final oral examination covers principally the work of the thesis, and according to Institute regulations must be held at least two weeks before the degree is conferred. A digital copy of the thesis is required for the Institute Library, including both PDF and original source files. Both should be deposited into CaltechTHESIS. Caltech-Kaiser Permanente School of Medicine MD/PhD Program There is a dual-degree program between Caltech and the Kaiser Permanente School of Medicine (KPSOM) for the granting of the M.D./Ph.D. degree. Students receive their medical training at KPSOM, and perform their Ph.D. work with any member of the Caltech faculty. Admission to this dual-degree program is made through the KPSOM M.D./Ph.D. process. The M.D. degree is awarded by KPSOM, and the Ph.D. is awarded by Caltech. The dual-degree program is directed by Dr. Jose M. Barral at KPSOM and Professor Paul Sternberg at Caltech. For more information, see medschool.kp.org/education/curriculum#dual-degrees. Caltech-UCLA Medical Scientist Training Program (MSTP) A joint program between Caltech and the UCLA Medical School has been established for the granting of the M.D./Ph.D. degree. Students do their preclinical and clinical work at UCLA, and their Ph.D. work with any member of the Caltech faculty, including the biology, chemistry, and engineering and applied science divisions. Admission to this joint program is made through the usual UCLA MSTP process, checking a box indicating interest in the Caltech option. Students will be accepted into the joint program, funds permitting. The M.D. degree would be from UCLA and the Ph.D. would be awarded by Caltech. The current Directors of the UCLA MSTP are Dr. Olujimi Ajijola and Dr. David Dawson, and Caltech Professor Mitch Guttman is the Associate Director. For more information, see mstp.healthsciences.ucla.edu. Caltech-USC MD/PhD Program A joint program between Caltech and the USC (Keck) Medical School has been established for the granting of the M.D./Ph.D. degree. Students do their preclinical and clinical work at USC, and their Ph.D. work with any member of the Caltech faculty. Admission to this joint program is made through the usual USC process, checking a box indicating interest in the Caltech option. Special Regulations for Graduate Options 419 420 Students will be accepted into the joint program, funds permitting. The M.D. degree would be from USC and the Ph.D. would be awarded by Caltech. he current Director of the USC M.D./Ph.D. program is Dr. Davi inton. The Director for Caltech is Professor Paul Sternbera. For mor information, see keck.usc.edu/md-phd-program. Bi Subject Minor A student majoring in any non-biology option of the Institute may, with the approval of the Division of Biology and Biological Engineering, elect a subject minor in any of the subjects listed above under major subjects of specialization. Requirements for such a minor are determined by the faculty committee designated for each subject. A minor program in Biology is also available to students of other divisions. Such a program shall consist of 45 units of upper division course work in the Division of Biology and Biological Engineering, with each course passed with a grade of C or better. Approval of each program must be obtained from the Biology graduate option representative. A student majoring in another division who elects a subject minor in Biology may, if desired, arrange to have the minor designated as Biology, rather than with the name of the specific minor subject. CHEMICAL ENGINEERING (CHE) Aims and Scope of the Graduate Programs The general objective of the graduate work in chemical engineering is to produce individuals who are exceptionally well trained to apply mathematics, the physical, chemical, and biological sciences, and engineering to the understanding of systems involving chemical reactions, transport phenomena, and materials/energy transformations, and to the development of new processes and materials. The program also strives to develop in each student self-reliance, creativity, professional ethics, and an appreciation of the societal impact of chemical engineering and the importance of continuing intellectual growth. ChE Admission It is expected that each applicant for graduate study in chemical engineering will have studied mathematics, physics, chemistry, biology, and chemical engineering to the extent that these subjects are covered in the required undergraduate courses at Caltech. In case the applicant's training is not equivalent, admission may be granted but the option may prescribe additional work in these subjects before recommending them as a candidate for a degree. ChE Master's Degree Although there is no formal M.S. program in ChE, in the course of their Ph.D. program students may apply for an M.S. degree by submitting an approved thesis and meeting all the other institute requirements for the M.S. program. The thesis must be approved by both the student's adviser and option representative. Information for Graduate Students Course Requirements At least 135 units of coursework must be completed in order to satisfy the Institute requirements. These units must include ChE 151ab, ChE 152, ChE/Ch 165, 18 additional units of advanced courses in chemical engineering, 27 units of science or engineering electives, and 18 units of general electives. With advanced permission from the option representative, general electives may include courses in the humanities and social sciences. A student must maintain a GPA of ≥ 2.0 to qualify for an M.S. degree. Finally, the M.S. requirements terms of research under the supervision of a chemical engineering faculty member. Research Report At least three weeks before the degree is to be conferred, a research report on the work performed under Che 280 must be submitted to both the student's adviser and the option representative. ChE Degree of Doctor of Philosophy 1. Coursework • Initial Consultation: Upon arrival at Caltech, the ChE Ph.D. students will meet with the ChE option representative to discuss the program, adviser selection, and expectations for the first and second terms. During these two terms, students are expected to take a normal load of three courses per term plus 9 units of research (ChE 280) to cover the rotation (see below). The courses during the first term include one each in advanced Kinetics (ChE 152) and Thermodynamics (ChE 165), and a third course in an area of need or an area that lines up with the research interests of the student. The courses during the second term include one each in advanced Transport (ChE 151 a) and Statistical Thermodynamics (ChE 164) and a third course as above. The third course taken during the first and second terms must be at least 9 units and graded. The entire first year of study will also be discussed. • Course Requirements: During the first year, Ph.D. students are required to take the five core courses: ChE 151ab, ChE 152, ChE 164, ChE 165, plus one additional ChE course from the following list: ChE 112, 115, Ch/ChE 140, 147, 148, 155, ChE/ESE 157, 158, 159, BE/ChE 163, 174. The core courses must be graded and a minimum grade of B- is required in each one. There is also a minimum GPA requirement of 2.5 each term of all courses taken. Failure to meet these grade and GPA requirements places the student in a state of deficiency, which may lead to termination of the program if not corrected promptly. • Subject Minor or External Coursework: Each student is required to complete either a subject minor or a general program of courses outside chemical engineering. The general program of courses consists of at least 54 units. A maximum of 27 units from the following list of doubly-listed courses can be used by Special Regulations for Graduate Options 421 422 graduate students as part of the 54-unit requirement: ESE/ChE 158; ChE/Ch 140, 147, 148, 155, ESE/Ge/Ch 171. A course in the ACM 100ab sequence will be credited 9 units instead of the nominal 12 units as listed in the catalog. Courses in the Humanities, Arts, and Linguistics are explicitly excluded from the general program. The requirements for a subject minor in other options may be found in the current Caltech Catalog. The general program of courses must be submitted and approved by the Option Representative after the candidacy exam. All courses chosen must be at the graduate level and should constitute an integrated program of study rather than a randomly chosen collection of courses outside chemical engineering. A grade of C or better is required in any of these courses to remain qualified for the Ph.D. program. 2. Research Adviser The choice of a research adviser is perhaps the most important decision a graduate student makes during the first year of graduate study. This decision must be made before the end of the second term of the first year, and so it is reasonable to devote significant thought and effort to this task before then. In the first two weeks of the fall quarter, all faculty will present overviews of their research program during informal evening sessions. All first-year students must attend all of these sessions. Following these presentations, the students are expected to meet individually with at least two faculty members to discuss proposed research projects and the possibility of doing a rotation in that faculty member's group during the first or second terms. All students must formally join a group by the end of the second term. 3. Rotations Rotations serve to acquaint the student with a group's research area and style. Two rotations are required. During a rotation, the student must participate in research activities in the chosen group for at least nine hours per week under the tutelage of a faculty or senior group member. At the end of a rotation, the student must produce a research report and give a group presentation. The report, signed by the rotation advisor, is forward to the ChE option representative. If the student and the faculty member decide that the "match" of research interests and personalities is good, the student may remain the the same group for a second rotation, effectively joining the group. Otherwise, the student should proceed to do a second rotation in another group with the same requirements as above. All students must find advisers and formally join a group by the end of the second term. 4. Candidacy Exam All students are required to pass the candidacy examination, ideally before the official start of the second year, or at the latest by October 15 of the second year. This oral exam is administered by a Candidacy Committee and consists of two parts: Information for Graduate Students • A presentation by the student based on the contents of a research progress report. • A background questions part broadly related to the research problem presented. The research progress report must be submitted to the Candidacy Committee members and the ChE option representative by August 31 of the first year in residence. The report should expound on the research pursued by the student and is expected to exhibit originality and a professional quality of exposition. It should outline the research problem, the proposed approach, the expected contributions in the general problem area, and the progress of the student at the time of writing. It should also provide clear evidence of the student's understanding of the research topic, the underlying science and technology related to that research, and the student's mastering of the relevant techniques and methodology necessary to pursue the proposed research. voting members of the Caltech faculty, with at least three being chemical engineering faculty. To ensure the impartiality of the committee, the chairperson and at least one more of the committee members must have no direct advisory relationship with the candidate. The choice of the oral exam committee will be made by the student and their research adviser and must be approved by the ChE option representative. It is the responsibility of the student to obtain approval from each proposed committee member for the date and time of the oral exam. The list of the recommended committee members must be submitted to the Option Representative at the same time as the research progress report. The second component of the oral exam consists of chemical engineering background questions relating broadly to the student's research topic. The chairperson of the Candidacy Committee shall be responsible for ensuring that the questions are at an appropriate level, consistent with that of undergraduates at Caltech. For example, if the Ph.D. focus is on heterogeneous catalysis, the student must be able to answer questions on basics such as: surface reaction mechanisms, diffusion/reaction in porous media, and multi-component gas-phase transport, etc. Similar considerations apply to Ph.D. projects related to fluid mechanics, thermodynamics, basic biology, physics, chemistry, etc. The advanced courses taken during the first year should help you prepare well for this part of the exam. Serious gaps in the understanding of classical chemical engineering concepts, approaches, and methodologies applicable to your research may lead to failing the exam even if research progress is deemed adequate. Furthermore, for interdisciplinary projects going beyond classical chemical engineering, the student will be expected to demonstrate good understanding of the fundamentals in other areas directly relevant to their project. The candidacy exam may have three outcomes: Pass, Conditional Pass, or Fail. Passing the candidacy exam admits the student to candidacy for the Degree of Doctor of Philosophy. Failing the Special Regulations for Graduate Options 423 424 candidacy exam terminates the student's Ph.D. program at Caltech. When course requirements are met, the student may be awarded an M.S. degree at the recommendation of the Candidacy Committee. Conditional Pass is a special outcome granted only when the student has clearly passed the background questions component, but the committee deems that more is needed on the research front. In this case, the committee chair will put in writing what is required and the time frame to meet those requirements. Under no circumstances is this time to exceed one term. Meeting the stipulated requirements must be reflected in a revised candidacy report, which must be submitted to and approved by the Candidacy Committee by the set deadline. It is at the discretion of the committee to request a re-examination. In any case, a Pass or Fail decision must be reached at the latest by December 15 of the second year in residence. This is a hard deadline for both the student and the committee. If there is no communication to the ChE option representative by December 15, a Fail decision will be entered automatically. 5. Thesis Review Committee After the student passes the candidacy exam, the Candidacy Committee becomes the "de-facto" Thesis Review Committee, which will be responsible for reviewing the student's progress. The committee must be convened (as a group) during the third year of residency, and every year thereafter to review progress, suggest improvements in research, or resolve any issues that could potentially delay graduation beyond the fifth year of residency. It is the responsibility of the student to organize the annual meetings of the Thesis Review Committee, which may be convened at any time during the year but at least three months before registration for the next academic year is due. Subsequent registration beyond the fourth year is subject to written approval by the Thesis Review Committee and the Che option representative. In order to expedite the review, the student should submit a two- or three-page concise outline of progress and of proposed future research to each member of their committee before the annual review meeting. 6. Final Thesis and Oral Defense As a final step in the Ph.D. program, the student is required to submit a satisfactory thesis, present a ChE seminar (open to the general public), and pass a final oral examination. Procedures for Seminar, Exam, and Committee Selection: At least three weeks prior to the exam date, the ChE Graduate Records Secretary must be given the title of the seminar, date, time and location. Both the seminar and exam should be scheduled on the same day, with the exam immediately following the seminar. The committee members will be determined by the student and their research adviser, and must be approved by the ChE option representative and the dean of graduate studies. The examining committee must include at least four members, of which at least three are voting members of the Caltech faculty and at least two are ChE faculty; one member of the committee may be from off-campus with Information for Graduate Students prior approval of the ChE option representative. 7. Graduate Teaching Assignment Duties All Ph.D. students are required to perform a minimum of 24 term-hours of GTA duties within the ChE Department during their studies. The GTA duties will normally be assigned after the first year in residence. Most students find the teaching assistantship a valuable experience for their future careers. Teaching assistantships outside ChE are permitted but the hours do not count toward the 24-hour TA requirement. Additional Information Additional information about graduate study requirements and procedures is provided in the chemical engineering graduate studies guide, distributed annually to first-year chemical engineering graduate students. CHEMISTRY (CH) The Caltech chemistry option offers a program of graduate study leading to the Ph.D. degree, with the goal of preparing students for a lifetime of independent research and scientific leadership in the chemical sciences, through careers in academia, industry, or government. Modern chemistry strives to achieve a molecular-level understanding of the natural world and thus forms the basis for much of modern science, including biology, medicine, materials, nanotechnology, energy and environment. The program of study, while anchored in the traditional areas of organic chemistry, inorganic chemistry, chemical biology, biochemistry and biophysics, chemical physics, and theoretical chemistry, is flexible and highly interdisciplinary. The graduate program in chemistry emphasizes research. This emphasis reflects the Institute's traditional leadership in chemical research and the conviction that has permeated the Division of Chemistry and Chemical Engineering from its founding, that participation in original research is the best way to awaken, develop, and give direction to creativity. The program is designed to encourage students to begin their research early in their first year. Students can elect to do research that crosses the boundaries of traditionally separate areas of chemistry, for in this relatively compact division, they are encouraged to go where their scientific curiosity drives them. A thesis that involves more than one adviser is not uncommon, and interdisciplinary programs with biology, physics, geology, chemical engineering, and environmental science and engineering science are open and encouraged. An extensive program of seminars will enable students to hear of and discuss notable work in chemical physics, organic chemistry, inorganic chemistry and electrochemistry, organometallic chemistry, and biochemistry and molecular biophysics. Graduate students are also encouraged to attend seminars in other divisions. Special Regulations for Graduate Options 425 426 Ch Learning Outcomes Students upon whom are conferred the Ph.D. degree have provided evidence of independent scholarship and scientific creativity through the performance of original research, which is described in their doctoral thesis and defended orally. Students must also demonstrate an ability to conceive new research directions by preparing and defending a set of written research propositions. Ch Course Program A student is required to complete at least five courses, each being nine units or more, in science or engineering. At least one course must be in a field substantially outside the research area of the student. Courses may be either inside or outside the chemistry option, must be numbered 100 or greater, and must be taken on a letter-grade basis with a grade of B or above. The student should discuss, with his or her adviser, which courses best serve his or her individual needs. The program of courses must be approved by the research adviser and by the Chemistry Graduate Study Committee. Ch Master's Degree Students are not ordinarily admitted to graduate work leading to an M.S. degree. Under special circumstances, and with prior approval of the Graduate Study Committee, a master's degree can be obtained. All master's programs for the degree in chemistry must include at least 45 units of chemical research and must satisfy the Course Program described above. The remaining electives may be satisfied by advanced work in any area of mathematics, science or engineering, or by chemical research. A satisfactory thesis describing this research, including a one-page digest or summary of the main results obtained, must be submitted to the divisional graduate studies office at least 10 days before the degree is to be conferred. In addition, the fulfillment of the thesis requirement must be signed off by a designated faculty member on the M.S. candidacy form and a final copy of the thesis submitted to the Graduate Office no later than two weeks before the degree is to be conferred. The copies of the thesis should be prepared according to the directions formulated by the dean of graduate studies and should be accompanied by a statement of approval of the thesis, signed by the adviser directing the research and by the chair of the Chemistry Graduate Study Committee. Ch Degree of Doctor of Philosophy Selecting a Research Project Soon after a new graduate student arrives in the laboratories, they attend a series of orientation seminars that introduce students to the active research interests of the faculty. Students then meet with each of five or more faculty whose fields attract them, to discuss in detail potential research problems. They eventually settle upon the outlines of a research problem that interests them and select a specific research adviser (or set of co-advisers). Neither students nor faculty can make a commitment to an adviser-advisee relationship prior to the end of the first month of the fall term. Students typically begin Information for Graduate Students research during their first academic year. Candidacy To be recommended for candidacy for the doctor's degree in chemistry, in addition to demonstrating an understanding and knowledge of the fundamentals of chemistry, a student must give satisfactory evidence of proficiency at a high level in the primary field of interest, as approved by the division. This is accomplished by an oral candidacy examination, which must be held during or before the fifth term of graduate residence (excluding summer terms). The candidacy committee shall consist of the thesis advisers) and two additional faculty members; at least two of the three members must be chemistry faculty. The committee should be considered as a resource for the student for the remainder of his or her studies. At the candidacy examination, a student is asked to demonstrate scientific and professional competence and promise by discussing a research report and propositions as described below. The research report should describe progress and accomplishments to date and plans for future research. Two original research propositions, or brief scientific theses, must accompany the report, and at least one must be well removed from the student's field of research. These propositions should reflect his or her breadth of familiarity with the literature, originality, and ability to pose and analyze suitable scientific research problems. The research report and propositions must be in the hands of the examining committee as a bound, hard-copy document one week before the examination. The result of the candidacy examination may be either (a) pass, (b) fail, or (c) conditional. Conditional status is granted when the committee decides that deficiencies in a student's research report, propositions, or overall progress can be remedied in a specific and relatively brief period of time. In order to change conditional to pass status, the student must correct the indicated deficiencies or in some cases schedule a new examination the following term. The student must be admitted to candidacy at least three terms before the final oral examination. A student cannot continue graduate work in chemistry (nor can financial assistance be continued) past the end of the sixth term of residence without being admitted to candidacy, except by petitioning the division for special permission. This permission, to be requested by a petition submitted to the Graduate Study Committee stating a proposed timetable for correction of deficiencies, must be submitted before registration for each subsequent term (including the summer following the sixth term of residence) until admission to candidacy is achieved. Graduate Teaching Assignment Duties All Ph.D. students are required to perform a minimum of one 9 term-hour GTA within the chemistry option before the completion of the fourth year of study. Most students find the teaching assistantship a valuable experience for their future careers. Special Regulations for Graduate Options 427 428 Language Requirement There is no formal foreign language requirement for the Ph.D. in chemistry. However, the division believes strongly in the professional importance to chemists of knowledge of foreign languages and encourages their study prior to graduate work or while in graduate school. Ph.D. Thesis Committee In the third year, the student in consultation with their adviser will form their Ph.D. thesis committee. This committee will comprise at least four faculty members and will generally consist of the original candidacy committee plus an additional member of the faculty; at least three of the members must be from the chemistry option. The student must meet with their committee annually, beginning in the third year. At these informal meetings, the student will update the committee on the status of their research. Typically, a student will provide an updated CV, a short research summary (2-3 pages), and a brief outline of plans for the coming year. Fourth Year Progress Meeting Before the 13th academic term of graduate residence (excluding summer terms), the student will be expected to demonstrate satisfactory progress in the course of thesis research. To this end, an informal meeting with the Ph.D. thesis committee will be held. Typically, a student provides an updated CV, a short research summary (2-3 pages), a thesis outline with %-completed for each chapter, and a timeline for completion of the degree. At the meeting, the student will likely present an oral summary of research completed to date as well as an outline of future research plans. Following the discussion, an appropriate timetable for completion of the degree requirements will be discussed and agreed upon. It is also common to Length of Graduate Residence Any graduate student who anticipates a need to register for a 24th academic term must hold a meeting of his or her thesis committee and present the institute-required petition for permission to register that includes a plan of action for the period of the requested registration and a specific date for the completion of the degree requirements. This petition must be approved by the Thesis Committee, by the chair of the Chemistry Graduate Study Committee and, in cases where financial support is an issue, by the executive officer or division chair, before it is forwarded to the dean of graduate studies. Financial support of graduate students who are required to petition to register will not normally be provided through teaching assistantships. Failure to complete the degree requirements by the date specified in the petition would require the entire approval process to be repeated. This process must be repeated for every subsequent year. Information for Graduate Students Thesis and Final Examination The final examination will consist in part of the oral presentation and defense of a brief résumé of the student's research and in part of the defense of a set of propositions they prepare. Three original research propositions are required. No more than one of these may be a carryover from the candidacy examination, and at least one must be well removed from the field of research. Each proposition shall be stated explicitly and the argument presented in writing with adequate documentation. The propositions should display originality, breadth of interest, and soundness of training; a student will be judged on the selection and formulation of the propositions as well as on the defense of them. Formulating a set of propositions should begin early in the course of graduate study. To emphasize the importance of these propositions, there will be a separate examination on the three propositions by the Ph.D. thesis committee. This examination on the propositions is normally taken after the thesis research progress meeting, but not less than 10 weeks in advance of the final doctoral examination. A copy of the propositions, along with suitable abstracts, must be submitted to the examining committee not less than two weeks before the propositions examination. These propositions must be acceptable to the committee before the final doctoral examination can be scheduled. A copy of the thesis must be submitted to each member of the thesis committee not less than two weeks before the final doctoral examination. A copy of the thesis should also be submitted to the Graduate Office for proofreading three weeks prior to the final doctoral examination. Two final copies (one on Permalife paper) are to be submitted to the Graduate Office. Ch Subject Minor Graduate students in other options taking chemistry as a subject minor will be assigned a faculty adviser in chemistry by the Chemistry Graduate Study Committee. In consultation with this adviser, the student will work out an integrated program of courses, including at least 45 units of formal course work at the 100 level or above. This program must be approved by the Chemistry Graduate Study Committee, and a grade point average of 3.0 in the approved program will be required. CIVIL ENGINEERING (CE) Aims and Scope of the Graduate Program Civil Engineering (CE) research and study are offered through the Department of Mechanical and Civil Engineering (MCE). The degrees of Doctor of Philosophy (Ph.D.) and Master of Science (M.S.) are offered. In general, students who intend to work full-time toward the Ph.D. degree as a final degree objective are admitted to the Civil Engineering Graduate Program. The M.S. degree is typically only awarded to students who pursue the Ph.D. degree in civil engineering at Caltech and who do not already have an M.S. degree in civil engineering. Special Regulations for Graduate Options 429 430 The aim of the graduate program in civil engineering at Caltech is to prepare students for research and professional practice in an era of rapidly advancing interdisciplinary technology. The program combines individual depth of experience and competence in a particular chosen major specialty, with a strong background in the basic and engineering sciences. It strives to develop professional independence, creativity, leadership, and the capacity for continuing professional and intellectual growth. CE Preparation for the Graduate Program Entering graduate students are expected to have a thorough background in undergraduate mathematics, physics, and engineering. While a strong undergraduate program in civil engineering should provide a suitable preparation, students who have not specialized in civil engineering as undergraduates may also be admitted for graduate study. For example, an outstanding four-year undergraduate program in mathematics and sciences may provide a suitable background as well. The qualifications of each applicant will be considered individually, and, after being enrolled, the student will arrange their program in consultation with a member of the faculty. CE Master's Degree The degree of Master of Science in civil engineering is only awarded to students who do not already have an M.S. degree in civil engineering. The degree will be awarded upon request by students who have fulfilled the requirements. Only in exceptional cases is there admission to the M.S. program as the final degree objective. A minimum of 138 units of courses numbered 100 or above, which meet the required master's program listed below, must be passed with a grade of at least C for completion of the master's degree in civil engineering. All units must be taken for grades, except for courses offered only on a pass/fail basis. The M.S. degree in civil engineering is typically completed within the first two years of residency at Caltech. Each student's program must be approved by the adviser and option representative in mechanical and civil engineering before registering for the course. Required Master's Program 1. Graduate civil engineering core (45 units). These units should provide a solid base for the student's engineering interest. The courses should be selected from the Core CE subjects listed under the of the Degree of Doctor of Philosophy Description and Requirements section. 2. Mathematics, engineering, and research electives, except seminar courses (63 units). Research can be included up to a maximum of 27 units. 3. Free electives (27 units). Any course with a number of 100 or greater may be selected, except that research units and seminar courses can not be included. 4. Graduate Engineering Seminar, AM/CE/ME 150 abc (3 units). Information for Graduate Students CE Degree of Doctor of Philosophy The Ph.D. degree in civil engineering is focused on research. Study and research programs for the Ph.D. degree are individually planned to fit the interests and background of the student. A comprehensive research project resulting in an original contribution to the field, which is documented by a thesis, is required. Institute requirements for the Ph.D. degree are described in the section on degree requirements. A minimum of three academic years in residence as a graduate student are required by the Institute, and two or more additional years are usually needed for preparation of the thesis. Advising and Thesis Supervision An interim adviser is appointed for each student upon admission to a graduate degree in civil engineering. The interim adviser will serve as the primary mentor until the student finds a research adviser. It is the responsibility of the student to find an academic and research adviser within three terms of graduate residence at Caltech. In consultation with the adviser, the student must form a Ph.D. Thesis Advisory Committee within four terms of graduate residence at Caltech. This committee shall consist of at least three members of the Caltech professorial faculty, with at least two members from the faculty in mechanical and civil engineering. The committee shall meet as requested by the student. Further, the committee shall meet annually to review progress and to approve the registration of the student beyond the fifth year of graduate residence at Caltech. The adviser and the Thesis Advisory Committee provide the majority of mentoring to the student. In addition, the Option Representative and other members of the faculty are always available to provide advice and mentoring on any aspect of research, progress toward the Ph.D., future careers, and other aspects of graduate school. Admission to Candidacy To be recommended for candidacy for the Ph.D. degree in civil engineering, the student must, in addition to meeting the general Institute requirements, do the following: • Obtain the agreement of a professorial faculty member to serve as the students academic and research adviser before the end of the third term of graduate residence at Caltech. In consultation with the adviser, the student must form a Ph.D. Thesis Advisory Committee before the end of the fourth term. This committee shall consist of at least three members of the Caltech professorial faculty, with at least two members from the faculty in mechanical and civil engineering. • Pass both subject and research components of the oral candidacy examination before the end of the eighth term of graduate academic residence at Caltech. If the student has chosen a subject minor, an examination on the subject of that program may be included at the request of the discipline offering the subject minor. Special Regulations for Graduate Options 431 432 • Complete a minimum of 195 units of courses numbered 101 or above, that fulfill the required Ph.D. program listed below.

Registration Beyond the Sixth Year of Graduate Residence The annual approval of the Ph.D. Thesis Advisory Committee is necessary for registration beyond the 24th academic term of graduate residence at Caltech. Thesis and Final Examination The thesis examination will be given after the thesis has been formally completed. This examination will be a defense of the doctoral thesis and a test of the candidate's knowledge in the specialized field of research. The format of the examination can be chosen from the following two options, by the student, in consultation with the students research adviser: (i) a public seminar presented by the candidate, with an open question period, followed by a private examination by the Examining Committee or (ii) a private presentation to the Examining Committee followed by the examination, with a public seminar on another date. The Examining Committee shall consist of a minimum of four voting members, three of whom must be Caltech faculty; two Information for Graduate Students members must be from MCE. The Thesis Defense Committee shall be chaired by a committee member who is an MCE Caltech professorial faculty member and not the student's adviser. CE Subject Minor A student majoring in another branch of engineering or another division of the Institute may, with the approval of the faculty in the Department of Mechanical and Civil Engineering and the faculty in the students major field, elect civil engineering as a subject minor. The program of courses must differ markedly from the major subject of study or research, and must consist of at least 54 units of advanced courses (101 or above) approved by the faculty in mechanical and civil engineering. COMPUTATION AND NEURAL SYSTEMS (CNS) CNS Aims and Scope of the Graduate Program An integrated approach to graduate study combining computation and neural systems is organized jointly by the Division of Biology and Biological Engineering, the Division of Engineering and Applied Science, and the Division of the Humanities and Social Sciences. This curriculum is designed to promote a broad knowledge of aspects of molecular, cellular, and systems biology, cognitive neuroscience, computational biology and computational neuroscience, information and learning theory, emergent or collective systems, and computer science and electrical engineering in conjunction with an appropriate depth of knowledge in the particular field of the thesis research. For more details, see cns.caltech.edu. Admission Ideal applicants will have a Bachelor of Science degree or equivalent with a strong quantitative background and some facility with computer programming. They will have shown an interest in understanding the brain and/or in autonomous intelligent systems. The GRE tests (general and advanced subject) are not required and scores will not be considered for admission. Advisory Committee and TA Requirement An advisory committee of three CNS faculty members is constituted for each student by the CNS admissions committee upon admission to the program. The faculty in whose lab the student is staying first chairs this committee. The advisory committee meets with the student when they arrive, guides and approves first-year course choices, and answers questions and offers advice about the program and the way of life in CNS. The CNS faculty are available to students during the year for formal and/or informal discussions. It is expected that each graduate student will serve as a teaching assistant in one or two CNS courses during his or her residency at Caltech as part of the Ph.D. graduation requirement. Special Regulations for Graduate Options 433 434 CNS Master's Degree Only students who expect to pursue the Ph.D. degree will be admitted to the option. The master's degree may be awarded in exceptional cases. The awarding of this degree requires fulfilling the Institute requirements for a master's degree, satisfying the option breadth requirements (see following section), the completion of a master's thesis, and receiving from a candidacy examination oral committee a recommendation for awarding the degree. Laboratory Rotations Mandatory rotations through research groups (labs) provide a unique opportunity for the student to experience the CNS culture. To broaden the student's knowledge and to provide familiarity with different techniques and ways of thinking or doing research, each student should carry out three 12-week laboratory rotations (one per term) during the first year, and should engage in research. During each rotation, the student is expected to take part in the life and routine of the lab by attending lab meetings, participating in research projects and discussions with members of the lab, and meeting monthly with the faculty of that lab to discuss science. Course Requirements Six nine-unit courses are required during the first year: CNS/Bi/Ph/CS/NB 187, either Bi 9 or equivalent, or NB/Bi/CNS 150, a neurobiology or modeling course, a math course, and two other CNS, Bi, EE, ACM, or Ph courses (for example, a schedule of CNS/Bi/EE/CS/NB 186, CNS/Bi/Ph/CS/NB 187, NB/Bi/CNS 150, and CS/CNS/EE 156 satisfies this requirement). CNS students are required to take two additional classes: the one-unit survey course CNS 100, and the four-unit course Bi 252. These eight courses must be taken for letter grades. Students are free to take additional classes, and a research adviser may require that a student take a specific, complementary course as a requirement for joining his or her lab. Candidacy Four faculty, including the three faculty in whose labs rotations have been done, should be on the student's candidacy exam committee. At the end of the first year, the student is expected to decide on a research group and begin work there. The first summer is thus expected to be spent entirely on research in that lab. To be recommended for candidacy you are required to pass two tests: the general knowledge exam, and the research and candidacy exam. These exams are supervised by the CNS option representative. The general knowledge exam satisfies the breadth requirement. A list of about 100 questions, grouped by category, is available at www.cns.caltech.edu, providing a clear idea of the scope of knowledge that each student is expected to know well. Students are encouraged to organize working and discussion groups to prepare for this exam; the format and implementation of such a system, however, is left to the students. Information for Graduate Students This is an oral exam with the four faculty (including the heads of the student's three rotation labs and one other chosen for "breadth," of whom one can be from outside Caltech). It should be scheduled by the student (who contacts the committee members) to take place during the last six weeks of the third term of year one. For the exam, the student must answer questions (from more than one category) taken from the list, which is modified each year. (The exam can be retaken after three months. The research and candidacy exam satisfies the depth requirement. During year two, the student is expected to produce a piece of work of a quality sufficient to be presented at a professional meeting. (The objective of this description is to offer a way to calibrate the level of expected research achievement and involvement. Professional acceptance of the abstract or paper is not a requirement for passing candidacy.) This work is presented in an oral exam in spring term of year two, before the same exam committee (if possible) that conducted part one of the exam. The exam focuses exclusively on research (accomplished and/or planned). During year two, the student may take other courses, as needed, but is expected to present a high standard (quality, originality) of research at the time of this second part of the candidacy exam. Thesis Advisory Committee Once admitted to candidacy, the student chooses a Thesis Advisory Committee of at least three faculty. This committee serves as a source of advice independent of the Ph.D. adviser throughout the student's tenure. Each year, before the end of June, the student delivers a written progress report, followed by a meeting with the Thesis Advisory Committee. Thesis Examination Committee This committee should consist of a minimum of four voting members, three of whom must be Caltech faculty. The final oral examination covers principally the works of the thesis, and according to Institute regulations must be held at least three weeks before the degree is to be conferred. CNS Subject Minor Students majoring in other fields may take a subject minor in CNS, provided the program is supervised by a CNS adviser, is approved by the CNS option representative, and consists of 45 units, including NB/Bi/CNS 150, CNS/Bi/Ph/CS/NB 187, Bi 252, and other CNS cross-listed classes. A subject minor is not required for the Ph.D. degree in CNS. Special Regulations for Graduate Options 435 436 COMPUTATIONAL SCIENCE AND ENGINEERING (CSE) Aims and Scope of the Minor Computational science and engineering (CSE) may be pursued as a subject minor by graduate students who are pursuing Ph.D. degrees in any option. The CSE minor is intended to supplement one of Caltech's graduate degrees and is designed for students who wish to broaden their knowledge of CSE beyond their major field of study. The CSE minor is also intended to recognize graduate students' interest in and dedication to CSE as demonstrated by the successful completion of a program of study in the field. Completion of the CSE minor program of study will be recognized on the Ph.D. diploma by the statement, "...and by additional studies constituting a minor in Computational Science and Engineering." Requirements To receive the CSE minor, graduate students must fulfill the following requirements. • 18 units (two terms) from the following list: ACM/EE 106 ab, CMS/ACM/EE 122, ACM 114 ab, ACM 116, ACM 117, ACM 157, ACM 158, ACM 210 ab, ACM/IDS 216. • 18 units (two terms) from the following list: CS 115, CS 138 abc, CMS/CS 139 abc, CS 143, CS/IDS 150 ab, CMS/CS/CNS/EE/IDS 155, CS/CNS/EE 156 a, CS 179. • 9 units (one term) from the list: Ae/AM/CE/ME 214, Ae/AM/ME 232 ab, Ay 199, Ch 121 ab, GE 263, Ph/CS 219 abc. All courses to be applied toward the CSE minor requirements must be taken on a graded basis, and students must obtain a grade of B or higher in all courses. Courses that are used to satisfy the CSE minor cannot be used to satisfy course requirements in the major options unless absolutely required by the option. Courses taken as part of the CSE minor are counted toward the total number of units required for the completion of the Ph.D. degree. CSE Minor Administration The CSE minor is administered by an oversight committee consisting of three faculty members reporting to the chair of the engineering and applied science division. In consultation with their advisers and, if needed, with the CSE Oversight Committee, students formulate a program of approved courses individually tailored to each student's background and needs, with the objective that the student achieve a level of competence in specific subjects relevant to CSE. Students must petition the CSE Oversight Committee for approval of their program of study. Upon completion of the program of study, the CSE Oversight Committee will verify that the CSE minor requirements have been fulfilled. Information for Graduate Students COMPUTER SCIENCE (CS) Aims and Scope of the Graduate Program Graduate study in computer science within the Computing & Mathematical Sciences department is oriented principally toward Ph.D. research. The Ph.D. program requires a minimum of three academic years of residence; required coursework is generally completed within the first two years. Students must maintain high academic standards during their graduate residence. A student's Ph.D. research must exhibit originality in the formulation, analysis, and solution of a problem that is significant to the field of study. The option representative and executive officers are available to discuss concerns regarding academic progress. CS Master's Degree There is no terminal M.S. degree in Computer Science. In exceptional circumstances (typically when a student leaves the Ph.D. program without completing the degree), the option representative may approve the awarding of a M.S. degree, if the course requirements have been met and the student has passed the preliminary examination (both are described below). CS Degree of Doctor of Philosophy Course requirements Students must complete a minimum of 135 units of courses numbered 100 or greater, including research units (CS 280). Students should consult with their adviser to ensure balance in the selected courses. The coursework must include: • CMS 290 is required for all first year CS graduate students during each term (fall/winter/spring). • Advanced courses in computer science. Completion of a minimum of 54 units of CS courses numbered 100 or greater in addition to units earned for reading, research, and independent projects. Up to 24 of the 54 units may be taken from non-CS courses from CMS or ACM, including CMS/ACM/IDS 107, CMS/ACM/EE 122 and CMS 117, or other courses with approval from the option representative. Units outside computer science. Completion of a minimum of 27 units outside computer science. Courses jointly listed with computer science cannot be used to fulfill this requirement. Preliminary examination Toward the end of the first year, all incoming students must take a preliminary examination administered by the faculty. Its purpose is to ensure a solid and broad knowledge in computer science, and in the event of a deficiency, to direct the students to necessary courses and reading. Special Regulations for Graduate Options 437 438 Candidacy To be recommended for candidacy, a student must have completed the required coursework, have passed the preliminary examination, have entered upon a course of research approved by his or her thesis adviser, and have passed a candidacy oral examination. The candidacy oral examination is administered by a committee that consists of four faculty that is approved by the option representative. The chair of the committee must be a Caltech professorial faculty member distinct from the adviser. The examination ascertains the student's breadth and depth of preparation for research in the chosen area. The candidacy examination should be taken within the first three years of graduate study. Advising and Thesis Supervision In order to facilitate close supervision and a highly research-oriented environment, each student is admitted directly to an adviser and research group. A course of study is determined in consultation with the adviser. Occasionally students will be admitted into more than one group. Changes in affiliation may occur with the common consent of the student and the new adviser. Students meet regularly with their adviser throughout their time at Caltech, and are encouraged to do the same with other members of the faculty. Thesis and Final Examination A final oral examination will be scheduled and given after the Ph.D. thesis has been submitted for review to the student's adviser and thesis committee; the latter consists of at least four faculty approved by the option representative. The chair of the committee must be a Caltech professorial faculty member distinct from the adviser. The thesis examination is a defense of the thesis research and a test of the candidate's knowledge in his or her specialized fields. Subject Minor in Computer Science A subject minor is not required for the Ph.D. degree in computer science. However, students majoring in other fields may take a subject minor in computer science, provided the program is supervised by a computer science faculty adviser, is approved by the computer science option representative, and consists of 45 units sufficiently removed from the student's major program of study. COMPUTING AND MATHEMATICAL SCIENCE (CMS) Aims and Scope of Graduate Program Algorithmic thinking is emerging as a fundamental tool for all researchers, not just computer scientists. Algorithmic thinking now drives disciplines ranging from statistics and electrical engineering to biology and physics to economics and the social sciences. Computing and Mathematical Sciences (CMS) is an interdisciplinary Ph.D. program that trains students to apply algorithmic thinking to problems across science and engineering. Our research mission is to build the mathematical and algorithmic foundations required to move from data Information for Graduate Students to information to action. Students will study structures and mechanisms that store, process, and communicate information and that make decisions based on this information. These systems may be expressed in silicon and called computers, in lines of code called programs, or in abstract notation called mathematics. They may appear in economics as markets or social networks, as sequences of amino acids in DNA, or in the organic structure of the human brain. CMS Master's Degree Only students who expect to pursue the Ph.D. degree will be admitted to the option. The master's degree may be awarded in exceptional cases. The awarding of this degree requires fulfilling the Institute requirements for a master's degree, satisfying the core course requirements, and receiving a recommendation for awarding of the degree from the preliminary exam committee. CMS Degree of Doctor of Philosophy Institute requirements for the Ph.D. degree are described in the section on degree requirements. Approximately two years of coursework are required, and two or more years are usually needed for preparation of the dissertation. CMS Admission to Candidacy To be recommended for candidacy for the Ph.D. degree in computing and mathematical sciences the student must, in addition to meeting the general Institute requirements, do the following: Core requirement Each student will take six core CMS classes, three in applied mathematics (ACM) and three in Computer Science (CS). In both fields, at least two of the three classes will be taken the first year to prepare for the preliminary examination, while the remaining classes will be completed by the end of the student's second year. The core CMS classes are CMS/ACM/IDS 107, CMS/ACM/EE 122, CMS 117, CMS/CS/IDS 139, CMS/CS/EE/IDS 144, CMS/CS/CNS/IDS 155. These classes must be taken for a grade. Depth requirement: At least 27 units of courses in one particular subject area will be completed for a grade. The plan for these 27 units must be approved by the CMS option representative. Breadth requirement: At least 27 units of advanced courses in mathematics, engineering, science, or social science will be completed for a grade. The plan for these 27 units must be approved by the CMS option representative. Preliminary Examination All students must pass a preliminary examination on material from two CMS core classes in applied mathematics and two CMS core classes in computer science. The examination is administered by a committee consisting of at least three faculty selected by the CMS option representative. The exam will occur during the student's first year. Special Regulations for Graduate Options 439 440 Candidacy Examination All students must pass an oral candidacy examination to ascertain the breadth and depth of preparation for research in the chosen field. The examination will be administered by a committee that consists of at least four faculty, that is approved by the CMS option representative, and that satisfies Institute regulations. In particular, the chair of the candidacy committee must a faculty member distinct from the student's research adviser. The examination will occur during the student's first three years. CMS 290 is required for all CMS first-year graduate students during each term (fall/winter/spring). Advising and Thesis Supervision Upon admission, each student will be assigned a primary adviser in the option. This adviser will be replaced by a research adviser (possibly the same faculty member) once a direction of specialization is determined, and not later than the beginning of the second year. After completion of the candidacy exam, each student will form a thesis committee (possibly the same as the candidacy committee) that consists of at least four faculty, that is approved by the CMS option representative, and that satisfies Institute regulations. In particular, the chair of the thesis committee must be a faculty member distinct from the student's research adviser. The thesis committee will meet as needed, but no less than once a year, in order to advise the student. A final oral examination will be scheduled and given after the Ph.D. thesis has been submitted for review to the student's adviser and thesis committee. The thesis examination is a defense of the thesis research and a test of the candidate's knowledge in his or her specialized fields. Normally, the defense will consist of a one-hour public lecture followed by an examination of the thesis by the thesis committee. CONTROL AND DYNAMICAL SYSTEMS (CDS) Aims and Scope of the Graduate Program The option in control and dynamical systems (CDS) is open to students with an undergraduate degree in engineering, mathematics, or science. The qualifications of each applicant will be considered individually, and, after being enrolled, the student will arrange his or her program in consultation with a member of the faculty. In some cases the student may be required to make up undergraduate deficiencies in engineering science courses. The CDS option, as part of the Computing and Mathematical Sciences department, emphasizes the interdisciplinary nature of modern theory of dynamical systems and control. The curriculum is designed to promote a broad knowledge of mathematical and experimental techniques in dynamical systems theory and control. In addition to taking courses in the CDS option, students must select a focus area (see below). Information for Graduate Students CDS Master's Degree Students will be admitted to the option who expect to pursue the Ph.D. degree. The master's degree may be awarded in exceptional cases. The awarding of this degree requires fulfilling the Institute requirements for a master's degree, satisfying the focus requirements, and receiving a recommendation for awarding of the degree from the candidacy oral examination committee. CDS Degree of Doctor of Philosophy Institute requirements for the Ph.D. degree are described in the section on degree requirements. Approximately two years of course work are required, and two or more years are usually needed for preparation of the dissertation. Admission to Candidacy To be recommended for candidacy for the Ph.D. degree in control and dynamical systems, the student must, in addition to meeting the general Institute requirements, do the following: • Complete the following courses: CDS 131, CDS 232, and CDS 231 or CDS 233. • Complete the following CMS/ACM courses: CMS/ACM/IDS 107, CMS/ACM/IDS 113, or CMS 117. • Complete an additional 36 units in CDS or other advanced courses in systems theory, dynamical systems, robotics, and/or applied mathematics. • Complete the focus requirement, consisting of at least 27 units in a particular area outside of CDS. Courses taken to satisfy the focus must represent a coherent program of advanced study in the chosen area. Possible areas include biological systems, computer science, environmental science, fluid dynamics, information and communications, networking, robotics, and space systems. The program of study must be approved by the student's counseling committee and the option representative. • Preliminary examination. Toward the end of the first year, all incoming students must take a preliminary examination administered by the faculty. Its purpose is to ensure a solid and broad knowledge in control and dynamical systems, and in the event of a deficiency, to direct the students to necessary courses and reading. : Prepare a research progress report. Pass an oral examination on the major topic of the student's research. The oral examination is normally taken no later than the end of the third year of graduate academic residence at the Institute. In addition, CMS 290 is required for all CDS first year graduate students during each term (fall/winter/spring). Special Regulations for Graduate Options 441 442 Advising and Thesis Supervision Upon admission, each student is assigned an adviser in the option, who will approve the initial course of study by the student. A preliminary exam given during the first year of study will be used to evaluate the student's preparation for continued study. The adviser will be replaced by a research adviser and a candidacy committee when the direction of specialization is determined, not later than the beginning of the second year. The candidacy exam is normally taken during the third year of study. The candidacy committee will be the judge of the completion of the engineering focus requirement, necessary before advancement to candidacy. The student's candidacy committee may be reconstituted as the thesis committee after the candidacy exam has been successfully completed. At the early stages of thesis preparation, the student's thesis committee will meet as needed to advise the student of his or her progress and to deal with any problems that might have arisen. A final oral examination will be given after the thesis has been formally completed. The thesis examination will be a defense of the doctoral thesis and a test of the candidate's knowledge in the specialized field of research. Normally this defense will consist of a one-hour public lecture followed by an examination of the thesis by the thesis committee. CDS Subject Minor A student majoring in another option at the Institute may elect a subject minor in control and dynamical systems. The student must obtain approval from the CDS faculty of a course of study containing at least 54 units of courses that are required for the CDS Ph.D. (see Advancement to Candidacy) or advanced courses with a CDS listing. ELECTRICAL ENGINEERING (EE) Aims and Scope of the Graduate Program Award of the Bachelor of Science degree may be followed by graduate study leading to the Master of Science degree in electrical engineering, and the more advanced degrees of Electrical Engineer or Doctor of Philosophy. Because admission to graduate studies in electrical engineering at Caltech is extremely competitive, the Admissions Committee attempts to select those applicants it judges both best qualified and best suited for the graduate program. The Graduate Record Examination (GRE) will not be required or considered for admission to the Ph.D. or M.S. degree programs in Electrical Engineering. The Degree of Doctor of Philosophy offers two tracks: EE only and Medical and Electrical Engineering (Med-EE). The Med-EE track is offered jointly by both departments of Electrical Engineering and Medical Engineering (see MedE Section), available to any students to graduate after Fall 2022; the single degree to be shown on the diploma is "Ph.D. in Medical and Electrical Engineering." Information for Graduate Students EE Master's Degree Normally, the master's degree in electrical engineering is completed in one academic year. The principal criteria for evaluating applicants for the MSEE are the excellence of their preparation for the math- and physics-oriented nature of Caltech's graduate courses, and the judgment of the Admissions Committee on their ability to successfully pursue and benefit from the course program. The Institute does not normally admit an applicant to the master's degree in a field in which the applicant already has a master's degree from another U.S. institution. Financial aid is seldom offered to those who intend to complete their graduate work with a master's degree. A joint B.S./M.S. degree is not available in electrical engineering. 135 units (100 or above) are required as approved by the electrical engineering graduate student adviser. No more than 30 units of pass/fail grades may be counted toward this requirement. Units toward this are not transferable from other schools. At least 54 units of EE letter-graded courses (courses listed or cross-listed as EE) labeled 100 or above and not counting EE 291 are required. EE 105 ac and EE 102, Electrical Engineering Seminar, is also required. Students are urged to consider including a humanities course in the remaining free electives. Students who have been admitted to the M.S.-only program must reapply if they are interested in the Ph.D. program. EE Degree of Electrical Engineer The engineer's degree may be awarded in exceptional cases. The awarding of this degree requires fulfilling the Institute requirements for an engineer's degree and receiving a recommendation for its awarding from the candidacy oral examination committee. EE Degree of Doctor of Philosophy As a rule, applicants who wish to undertake research work leading to a degree of Doctor of Philosophy in electrical engineering are admitted initially only for the MSEE. They are, however, evaluated according to additional criteria, the most important of which is the applicant's interest in and potential for research in one of the areas described below. The statement of purpose required as part of the application should clearly address this match. Considerable weight is also given to the opinions expressed in the applicant's letters of recommendation. During the Ph.D. applicant's master's degree year, evaluation continues. It is based in part on performance in courses and in part on a one-hour oral presentation scheduled early in the second quarter. As the year progresses, the electrical engineering faculty get to know the student, and the student makes contact with the professor in his or her area of research interest. Upon acceptance into a research group, the student begins research work and defers receiving the master's degree until formal admission into the Ph.D. program. In the event that the Adviser is not an EE faculty member, the student should meet with the EE Option Representative and develop an oversight plan to monitor progress. Before the end of his or her second academic year Special Regulations for Graduate Options 443 444 of graduate study, the student normally takes the Ph.D. qualifying oral examination. This must, however, be done no later than the end of the third academic year. Ph.D. applicants who already hold a master's degree in electrical engineering from another U.S. institution may be admitted directly to the Ph.D. program, but must provide sufficient information to obtain advance acceptance into a research group. Financial aid available to a Ph.D. applicant includes teaching assistantships and fellowships. TA duties consist of grading papers or lab instruction but not classroom lecturing. A fellowship may be supplemented by a teaching assistantship, and either or both include a full tuition scholarship. Tuition scholarships alone are not available. If financial aid is not requested, or if the box on the application form labeled "willing to come without aid" is checked, information on the source of funds for each year of intended graduate study must be included.

Students are strongly encouraged to do this before the end of the second year of residency. Ph.D. Committee The Ph.D. qualifying oral exam and the final defense exam are conducted by committees that are set up by the student and approved by the option representative. Members of these Ph.D. committees also serve as second or backup mentors in cases where such additional advising and problem solving are appropriate. Thesis and Final Examination The candidate is required to take a final oral examination covering the doctoral thesis and its significance in and relation to his or her major field. This final examination will be given no less than two weeks after the doctoral thesis has been presented in final form, and before its approval. This examination must be taken at least four weeks before the commencement at which the degree is to be granted. The Med-EE Ph.D. thesis must be related to both options. The final thesis defense exam is conducted by a committee that is set up by the student and approved by the option representative of the home department. The committee must be composed of 2 members from each option. The committee must include the advisor, but another member of the committee must be selected as chair. Special Regulations for Graduate Options 445 446 Advising and Thesis Supervision Periodic meetings between the advising faculty and the graduate student are an integral part of the Ph.D. program. These meetings should be at sufficiently frequent intervals, as determined by the student and adviser. Students are also encouraged to meet with other members of the Ph.D. committee, the option representative, the executive officer, or Caltech's ombudsperson to discuss problems relating to satisfactory progress. EE Subject Minor A student majoring in another option at the Institute may elect a subject minor in electrical engineering. The student must obtain approval from the electrical engineering faculty of a course of study containing at least 45 units (over the 100 level) of advanced courses with an EE listing (excluding 291). At least 36 of these should be for letter grades no lower than C. Undergraduate first-year classes cannot be counted toward this. ENVIRONMENTAL SCIENCE AND ENGINEERING (ESE) Aims and Scope of the Graduate Program The ESE graduate program trains doctoral students to solve fundamental problems in environmental science and engineering. The problems cut across traditional disciplinary boundaries and span space scales ranging from global to local. Students are trained to acquire a broad base of knowledge of environmental systems, including Earth's atmosphere, oceans, and biosphere. They deepen their knowledge in one or more focus areas, culminating in research leading to a Ph.D. thesis. Reflecting the interdisciplinary nature of research in the ESE program, the program unites faculty from the divisions of Geological and Planetary Sciences, Engineering and Applied Science, and Chemistry and Chemical Engineering. Admission Applicants for admission to the ESE program should have undergraduate preparation in science, engineering, or mathematics. Admission is limited to students intending to pursue the Ph.D. degree. Only students who intend to work full-time toward the Ph.D. degree are admitted. The application submission deadline is January 1. The admission process follows Institute regulations. The GRE general test and subject tests are not required. Self-reported scores will not be considered. International Students In order to be admitted for graduate study, students from non-English-speaking countries are expected to read, write, and speak English and comprehend the spoken language. Although not required for admission, for applicants whose native language is not English or have not received a degree from a university or college where English is the primary language of instruction, it is important to demonstrate a strong capability in English prior to admission to Information for Graduate Students Caltech. This can be done by self-reporting scores from the Educational Testing Service (TOEFL), Pearson Test of English Academic (PTE Academic), the Cambridge Examinations and the International English Language Testing System (IELTS), or other services that provide a certified English-language proficiency examination. The ESE faculty may also arrange an online interview while assessing applications. Advising An academic adviser is appointed for each incoming student to assist in designing his or her academic program. The research adviser is chosen by mutual agreement of the student and adviser during the second year of graduate study, after passing the Ph.D. qualifying examination. The Thesis Advisory Committee (TAC), consisting of four Caltech faculty members including the research adviser, should be constituted and meet with the student soon after the student passes the qualifying examination; thereafter, it should meet with the student annually to review progress and provide guidance and support. Committee membership may be changed if the student's research interests change. The TAC generally serves to recommend the student's advancement to candidacy; it may also serve as the examining committee for the final thesis defense. ESE Master's Degree Students enrolled in the Ph.D. program may be awarded a master's degree if they have satisfied the basic Institute requirement of 135 units of work in courses numbered 100 or higher. These courses must include those specifically required in the ESE Ph.D. program. ESE Degree of Doctor of Philosophy For the Ph.D. degree, the student must (1) satisfy the course requirements, (2) pass the qualifying examination, (3) advance to candidacy, and (4) complete a thesis and successfully defend it in a final oral examination. Course Requirements During their first year, students, in consultation with their academic advisers, must design a program of graduate study that includes a minimum of 135 units of graduate work to be completed before the end oftheir third year. The course program should take into account the students' individual backgrounds and focus areas, educate them broadly in fundamental questions and methods of contemporary environmental science and engineering, and prepare them for their research. The course program must include the core courses ESE 101, 102, and 103. Attendance at the weekly research seminars (ESE 104 and 110 abc) is required for first-year students and is expected of all graduate students. All students are expected to have knowledge of methods of applied mathematics and statistics on the level of graduate courses at Caltech. In cases of unusual preparation, students may petition to substitute a similar but more advanced course for one of the required courses. Special Regulations for Graduate Options 447 448 Additionally, students are required to take 36 units of elective courses from two of the three groups below: • Environmental Biology: ESE/Bi 166, ESE/Bi 168, Ge/ESE 170; • Environmental Chemistry: ESE/Ch 175, ESE/Ch 176, ESE/Ge/Ch • Environmental Physics: ESE 130-138, Ge/ESE 139, Ge/ESE 150, ESE/ChE 158. The remaining units of graduate work can be fulfilled by a combination of elective courses in ESE or related disciplines, reading or laboratory courses (ESE 100), and research (ESE 106, 300). Of the total required 135 units, no more than 45 units may be in research. No more than 27 research units may be taken during the first year of graduate study. Exceptions may be granted by petition. It is expected that each graduate student will, as part of the Ph.D. graduation requirement, serve as a teaching assistant for one course per year, following completion of the qualifying exam. Ph.D. Qualifying Examination The Ph.D. qualifying examination must be taken during the first term of the student's second year of residency. This examination consists principally of an oral defense of two research propositions, each advised by a different faculty member. Written abstracts must be submitted for both propositions, and one of them must be described in the form of a research report or proposal. The qualifying exam also covers the material of the ESE core courses and of the elective courses the student has taken. In preparation for the qualifying examination, students are encouraged to register for nine units of research (ESE 106) in their second and third terms of residency. Advancement to Candidacy Students are recommended to advance to candidacy following the successful completion of a candidacy exam with their Thesis Advisory Committee (TAC). The exam, consisting of both a written Ph.D. thesis proposal and an oral presentation of this plan is required, and must be approved by all TAC members. Advancement to candidacy, including all required course work, should be completed before the end of spring term in the student's third year of residency. Thesis and Final Examination Copies of the completed thesis must be provided to the examining committee two weeks before the final oral examination. The final oral examination focuses on the work of the thesis and, according to Institute regulations, must be held at least two weeks before the degree is conferred. ESE Subject Minor Graduate students majoring in another option at the Institute may elect a subject minor in ESE. The ESE minor is intended to supplement one of Caltech's graduate degrees and is designed for students who wish to broaden and deepen their expertise with knowledge in ESE. To Information for Graduate Students complete an ESE subject minor, graduate students must enroll in a program of study approved by the ESE option representative, which is to include at least 36 units over two or more terms of graduate-level ESE classes (ESE 100 and above) and 18 units over two or more terms of research under ESE 106 or ESE 300. At least one of the graduate-level ESE classes must be ESE 101, ESE 102, or ESE 103. GEOLOGICAL AND PLANETARY SCIENCES (GPS) (GEOLOGY, GEOBIOLOGY, GEOCHEMISTRY, GEOPHYSICS, PLANETARY SCIENCE) Aims and Scope of the Graduate Program Students in the Division of Geological and Planetary Sciences study the earth and planets to understand their origin, constitution, and development, and the effect of the resulting physical and chemical characteristics on the history of life, on the environment, and on humanity. Broad training in the fundamental sciences enriched by more specialized course work within the division forms the basis of the educational program. Students are encouraged to work with complex and often incomplete data sets, to undertake research in natural settings such as in the field or at sea, and to use the many modern laboratory facilities available within the division. Programs of study and research are pursued in environmental science and engineering, geobiology, geochemistry, geology, geophysics, and planetary science. The curriculum is flexible so that students with diverse degrees in science and engineering may carry out graduate work within the division. Interdisciplinary studies are encouraged and students may carry out academic and research programs within and between different divisions. The objective is to train students for future employment in academic research, government, and industry. Admission and Entrance Procedures Only students who intend to work full-time toward the Doctor of Philosophy (Ph.D.) degree are admitted. The application submission deadline for the GPS Division is January 1. The admission process follows Institute regulations. The GRE general test and subject tests are not required for any of the GPS options. Self-reported scores will not be considered. International Students In order to be admitted for graduate study, students from non-English-speaking countries are expected to read, write, and speak English and comprehend the spoken language. Although not required for admission, for applicants whose native language is not English or have not received a degree from a university or college where English is the primary language of instruction, it is important to demonstrate a strong capability in English prior to admission to Caltech. This can be done by self-reporting scores from the Educational Testing Service (TOEFL), Pearson Test of English Academic (PTE Academic), the Cambridge Examinations and the International English Language Testing System (IELTS), or other Special Regulations for Graduate Options 449 450 services that provide a certified English-language proficiency examination. The GPS faculty may also arrange an online interview while assessing applications. Based on their applications and interests, students enter one of the major subject options of the division and are given an academic adviser who is a professorial faculty member associated with the option. The six options are environmental science and engineering, geobiology, geochemistry, geology, geophysics, and planetary science. Students may later change options, but must first obtain approval from the new option. Each student must plan to satisfy the requirements for the Ph.D. degree in one option. Entering students in the week preceding the beginning of instruction for the first term meet with their option representatives to discuss their preparation in the basic sciences and select a series of courses that will best prepare them for research in their chosen field while meeting the requirements set forth below. First-year graduate students are encouraged to register for at least nine units of research (Ge 297) in each term of residence. The primary objective is to communicate to the students the excitement of discovery based on original investigations and to provide a broad scope of research aims. An important byproduct can be the formulation of propositions for the Ph.D. qualifying oral examination or orientation toward Ph.D. research. Advising and Thesis Supervision The option representative for each incoming student will act as the academic adviser in the first term. An academic adviser will be assigned by the start of second term. This appointed adviser will continue as mentor with broad responsibility for a student's academic welfare throughout the graduate program. During the second year, after passing the qualifying examination, each student should identify a professor as thesis adviser, who will normally provide a graduate research assistantship and the opportunity for continuing research. In consultation with the two faculty advisers, each student then forms a Thesis Advisory Committee (TAC), composed of at least four Caltech professors (chaired by the academic adviser). External scientists closely involved in the student's research may also be appointed. Members of the TAC serve as advisers, counselors, and resources, and its membership may be changed if a student's research interests change. The TAC meets with the student at least once each year for a progress review, and informally whenever the student needs or requests assistance or guidance. In addition, the faculty members in each option have their own systems for annual evaluations of student progress. A few months before completion of the thesis dissertation, the thesis examining committee will be chosen, usually including the members of the Thesis Advisory Committee. All students are urged to consult with division faculty in the following sequence if they have any problems: thesis and academic advisers, Thesis Advisory Committee, option representative, academic officer, and division chair. If these division personnel cannot resolve a Information for Graduate Students problem, then the student should turn to Institute offices. GPS Master's Degree Students enrolled in the Ph.D. program may be awarded a master's degree when they have satisfied the basic Institute requirement of 135 units. These courses must be part of a plan of study approved by the option representative, numbered 100 or higher, and part of those used to satisfy the Ph.D. requirement in one of the options of the division. A minimum of 72 units should be taken as courses, rather than research or independent study units. Specifically required are two courses from the list Ge 101, Ge 102, Ge 103, Ge 104, or ESE 101, ESE 102, ESE 103. An application for admission to candidacy for an M.S. degree must be submitted in REGIS according to the academic calendar in the Caltech Catalog. GPS Degree of Doctor of Philosophy Division Requirements For a Ph.D. degree, the student must 1) pass the qualifying oral examination, 2) satisfy course requirements of the division and of an option, and 3) complete a thesis and successfully defend it in a final oral examination. Recommendation to the dean of graduate studies for admission to candidacy occurs after the student has satisfied the first two requirements and has been accepted for thesis research by a division faculty member, who then becomes the student's thesis adviser. The qualifying examination consists of oral and written defense of two research propositions, supplemented by a written description of one of them. Students are encouraged to consult with various faculty members concerning their ideas on propositions, but the material submitted must represent the work of the student. There must be a different faculty member associated with each of the two propositions. The exam is normally taken early in the first term of the second year of residence and is administered by the qualifying examination committee, which has members from the six options of the division. A more detailed outline of the qualifying examination is available on the division website. By the end of the fall term of the second year, students are expected to select a thesis advisers) and before the end of the second year, the Thesis Advisory Committee will be selected, as outlined above. The division encourages students to engage in research early in their graduate careers. Students making normal progress will submit papers to refereed journals that have been approved by a faculty member of the division. The final oral examination for the doctorate by the thesis examining committee will be scheduled no sooner than two weeks following submission of the thesis (approved by the thesis adviser) and, in conformity with Institute regulations, it must be scheduled at least two weeks before the degree is to be conferred. Special Regulations for Graduate Options 451 452 Candidates are expected to publish the major results of their thesis work. The published papers should have a California Institute of Technology address. Published papers may be included in the thesis. By the end of the first academic year (third term): submission by the student of (1) tentative titles of propositions for review by the qualifying examination committee and (2) a list of courses planned to satisfy the Ph.D. requirement, for review by the option. By the end of the second academic year: (1) passage of oral exam; (2) approval by the option of courses planned to satisfy candidacy requirements; (3) submission of a tentative thesis topic and adviser, and Thesis Advisory Committee. By the end of the third academic year: (1) satisfactory completion of course requirements; (2) satisfactory completion of other requirements including selection of thesis topic and adviser, and Thesis Advisory Committee; (3) admission to candidacy. A student who has not been admitted to candidacy by the end of the third year will need permission of the academic officer to register. By the end of the fourth academic year: satisfactory progress toward completion of thesis. After completing the fifth academic year, the student must formally petition to register for each subsequent year. Financial aid will normally not be extended beyond the sixth year. The student's program and progress will be reviewed annually by his or her option and by the Thesis Advisory Committee. In cases where, in the opinion of the faculty in the option, the student is clearly not showing adequate progress, they may recommend to the division chair that the student be denied permission to continue in the Ph.D. program based upon their overall assessment of the student's performance. Basic Division Course Requirement During the first year, every graduate student will take two of the seven basic introductory courses Ge 101-104 and ESE 101-103, in areas in which the student has not had substantial training. These should be completed during the first year. Throughout their graduate careers, students are expected to attend departmental seminars and seminar courses led by visiting scientists. Beginning in the second academic year, students are required to serve as teaching assistants for one quarter per year they are in residence.

Typically, students will present on their research work each year. Information for Graduate Students GPS Subject Minor A student may, with the approval of the Division of Geological and Planetary Sciences, elect a minor in any one of the major subjects listed above. Such a subject minor will include at least 45 units in courses at the 100 level or higher. Normally, a member of the division faculty affiliated with the minor will participate in the student's oral thesis defense. HISTORY (H) The program for a subject minor in history must be approved by the executive officer for the humanities before the admission to candidacy. In addition to meeting general Institute requirements, the student must complete satisfactorily, with a grade of C or better, 45 units in advanced courses in history. HISTORY AND PHILOSOPHY OF SCIENCE (HPS) Graduate students in science, mathematics, or engineering may take a minor in history and philosophy of science (HPS). The graduate minor is devoted to the study of the historical evolution and philosophical underpinnings of the physical and biological sciences. Historical work in the minor includes the origins of experimental practice, the social and institutional contexts of science, the origins and applications of quantitative methods, specific developments since antiquity in physics, biology, and chemistry, as well as biographical and comparative studies. Philosophical research deals with issues in causation, explanation, scientific inference, the foundations of probability and decision theory, philosophy of mind and psychology, philosophy of neuroscience, and scientific fraud and misconduct. The minor thus fosters the acquisition of broad knowledge about the scientific enterprise and related foundational problems, as well as more detailed analysis of the progress of and philosophical problems in particular branches of science. It is a valuable supplement to a technical degree since it helps equip students to understand the nature of scientific progress and to grapple with the conceptual basis of science and its wider ramifications. Students who successfully complete the HPS minor will be recognized with official credit for the achievement on their transcripts. Requirements Graduate students who take an HPS minor are expected to complete Hum/H/HPS 10, HPS 102 ab, HPS/P| 120, at least three units of HPS 103, and 18 units of additional work in HPS, to be completed by taking courses in HPS/H or HPS/PI numbered 99 or higher. Students need not complete the requirements for the minor within the first two years of graduate study.

The prerequisites can be satisfied with equivalent courses with approval from the instructor. All courses used for fulfilling the IDS graduate minor requirements must be taken on a graded basis and students must obtain a grade of B or higher on all courses. Courses that are used to satisfy the minor requirements cannot be used to satisfy the requirements in the major options. MATERIALS SCIENCE (MS) Aims and Scope of the Graduate Program The graduate program is designed to give students an understanding of general phenomena in synthesis-structure-property relationships in all materials, plus a detailed understanding of phenomena for at least one broad class of materials such as: physical materials science (solid state physics, quantum mechanics); mechanical materials science (micromechanics, continuum mechanics); soft materials (polymer chemistry/physics, chemical bonding); or oxide materials science (mineralogy/mineral physics). After completing the Ph.D. program, students have pursued careers in teaching and research at colleges and universities, in research for government and industry, in the operation and control of manufacturing processes, and in management and development positions in the materials industry. Information for Graduate Students Students may enter the graduate program in materials science with undergraduate preparation in physics, chemistry, engineering, or materials science. Students interested in terminating their graduate study at the master's level are not normally admitted. Students in the Ph.D. program are required to complete a set of core courses, pass an oral candidacy examination, complete a thesis describing original research in materials science or a related field, and publicly defend their thesis work. MS Preparation for the Graduate Program Students who have not specialized in materials science as undergraduates, as well as those who have, may be admitted for graduate study. As preparation for advanced study and research, entering graduate students are expected to have a thorough background in undergraduate mathematics, physics, and engineering. An outstanding four-year undergraduate program in mathematics and sciences is also a suitable background. The qualifications of each applicant will be considered individually, and, after being enrolled, the student will arrange their course of study and research in consultation with members of the faculty and the materials science option representative. MS Master's Degree The degree of Master of Science in materials science is only awarded to students who do not already have an M.S. degree in Materials Science. The degree will be awarded upon request by students who have fulfilled the requirements. Only in exceptional cases is there admission to the M.S. program as the final degree objective. Each student is assigned to a member of the faculty who will serve as the student's adviser. The adviser and option representative for materials science will approve the student's course of study. Study for the degree of Master of Science in materials science will ordinarily require at least three terms of courses. The courses shall be chosen from the list of core courses below, although 27 units of research (MS 200 or equivalent) may be substituted for 27 units of lecture or laboratory courses. Completion of 111 units of these courses within two years with no grade less than a C constitutes the academic requirements for the M.S. degree. Graduate Coursework 1. Materials Science Core - 27 units a. MS 131, MS 132, MS 133 2. Thermodynamics - 27 units a. APh/MS 105abc or (ChE/Ch 164, ChE/Ch 165 + APh/MS 105c) or (Ae/ME 118 + APh/MS 105bc) 3. General Electives - 36 units Students are required to take at least 9 units on a) Specific Materials and at least 9 units on b) Fundamentals of Materials Behavior. a.

MS 110abc MS Degree of Doctor of Philosophy The doctoral program in materials science consists of a series of preparatory classes, followed by an oral candidacy exam, a written thesis, and a final oral thesis defense. The goals of this program are to develop excellence in a chosen field of specialization; to develop tools with which to assess problems outside the student's field of specialization; to develop sufficient strength in the physical sciences for self-education beyond formal training; and to cultivate the motivation and foresight to become a productive and influential leader. As such, the graduate program in materials science is designed to be a doctoral program and students are only admitted into the doctoral program. There is no separate master's program in materials science. The Ph.D. degree in materials science is focused on research. Study and research programs for the Ph.D. degree are individually planned to fit the interests and background of the student. A comprehensive research project resulting in an original contribution to the field documented by a dissertation is required. Residency A minimum of three academic years in residence as a graduate student are required by the Institute, and two or more additional years are usually needed for preparation of the thesis. Language Requirement There is no language requirement for the Ph.D. degree. Minor No minor is required for the Ph.D. degree. Students are, however, encouraged to take advanced courses appropriate to their particular interests. Information for Graduate Students Advising and Thesis Supervision An interim adviser is appointed for each student upon admission to a graduate degree in materials science (typically the materials science option representative). The interim adviser will serve as the primary mentor until the student finds a research adviser. In the first year (no later than the third term), each student must choose a research adviser who will have primary responsibility for supervising the student's course program and research. The important adviser-advisee relationship requires effort from both parties, and some general expectations are outlined earlier in this section of the catalog. In consultation with their research adviser, the student should then form a Ph.D. Thesis Advisory Committee. This four-member committee should include: (i) the student's adviser, and ii) at least three members of the Caltech professorial faculty. The research adviser and the Thesis Advisory Committee provide the majority of mentoring to the student, offering advice on research, progress toward the Ph.D., future careers, and other aspects of life in graduate school and as a professional scientist. Requirements for Candidacy for the Ph.D. Degree To be recommended for candidacy for the Ph.D. degree in Materials Science, the student must, in addition to meeting the general Institute requirements, do the following: 1. Courses. To continue in the graduate program, the student must maintain a B- average for each term. Advancement to candidacy requires the successful completion of the program listed under "Core Courses" above. Alternatively, if the student has taken equivalent courses elsewhere, they may prove competency to the instructor of the equivalent course at the Institute and request a waiver of the required course. With the Core Course requirements 1-5, students must complete a minimum of 111 units of courses, numbered 100 or above, before presenting themselves for Ph.D. candidacy. The coursework towards the Ph.D. degree in materials science is typically completed within the first two years of residency at Caltech. a. All courses must be passed with a grade of at least a C, except for courses taken on a pass/fail basis. b. Students must complete the degree progress report online. C. Alternate Subjects or Areas i. Students entering the program with advanced preparation may choose either to substitute more advanced courses in the topical areas shown or demonstrate competency to the course instructor. ii. Students may petition the materials science option representative to accept alternative subjects or areas, but such petitions must be submitted before the student registers for the courses. 2. Oral Candidacy Examination. This examination should be taken no later than the end of the student's second year of residence. The student's research adviser must be on the examining Special Regulations for Graduate Options 459 460 committee, but cannot serve as chair of the committee. The examination is based on the student's coursework, and how it is related to the student's planned research area. The student will be expected to deliver a half-hour oral presentation describing research to-date and will answer questions related to this work. This portion of the examination will be followed by more open-ended questions to test general proficiency in materials science. Students who fail the oral examination on their first attempt will be given additional guidelines for further study and an opportunity to retake the examination a second and final time if the committee so recommends. Students who fail the oral examination a second time cannot continue with doctoral studies leading to the Ph.D. Upon recommendation of the examining committee, however, a student may be granted a terminal master's degree. The approval of the materials science option representative is necessary for registration beyond the third year of graduate residence without successfully completing the candidacy exam. 3. Research Competence. The student must have a doctoral research adviser, and must have completed at least 18 units of MS 200. Students who fulfill the requirements above will be recommended for candidacy to the doctoral program and a master's degree (if applicable) in materials science. Ph.D. Thesis Requirements The candidate is to provide a draft copy of the completed thesis to the members of the examining committee (typically the same as the Thesis Advisory Committee) at least two weeks before the final oral examination. The date of the examination and the composition of the examining committee will not be approved by the dean of graduate studies until the thesis is submitted in completed form, i.e., ready for review by the dean, the members of the thesis committee, and the Graduate Office proofreader. Registration is required for the term in which the thesis defense is undertaken, but is not normally allowed beyond the last date of the term. For more information, please see the section entitled "Information for Graduate Students" in the Caltech Catalog. Ph.D. Final Examination The candidate is required to take a final oral examination covering the doctoral thesis and its significance in and relation to materials science. It will consist of a public thesis seminar and an associated oral examination on the thesis and related fields. The examining committee must consist of the student's adviser and three members of the Caltech professorial faculty. The chair of the examining committee must be a Caltech professorial faculty member distinct from the adviser. This examination will be held at least two weeks after the doctoral thesis has been presented in its final form, and prior to its approval. Information for Graduate Students Registration beyond the Sixth Year of Graduate Residence The annual approval of the student's Thesis Advisory Committee or option representative is necessary for registration beyond the eighteenth academic term of graduate residence at Caltech. A petition to continue work toward the Ph.D degree must also be approved by the dean of graduate studies. MS Subject Minor Graduate students majoring in another option at the Institute may elect a subject minor in materials science. They must obtain approval from the materials science option representative for a course of study containing at least 45 units of advanced courses with a grade of C or higher. Normally a member of the materials science faculty will participate in the candidacy examination in the student's major department. • Students cannot use courses required by their major option in fulfillment of this requirement. • Students interested in a minor must receive prior approval from the option representative in materials science, who will review and approve the proposed course of study. • It is recommended that this course of study include advanced courses spanning different subfields of materials science. MATHEMATICS AND MINOR (MA) Aims and Scope of the Graduate Program The principal aim of the graduate program is to develop the student's ability to do original research in mathematics. Independent and critical thinking is fostered by direct contact with faculty members. (Read more about the current research interests of the faculty.) Faculty advisers help students plan their programs of study leading to a Ph.D. in mathematics. Entering students are advised by the graduate option representative, who assists them in selecting appropriate courses, depending upon their previous studies. Ma Master's Degree Entering graduate students are admitted directly to the Ph.D. program, since the Institute does not offer a regular program in mathematics leading to the master's degree. A master's degree may be awarded in exceptional circumstances either as a terminal degree or preliminary to the Ph.D. Sufficiently advanced undergraduates may be admitted to graduate standing to pursue a master's degree simultaneously with the bachelor's program. The recipient of a master's degree will be expected to take 135 units in advanced mathematics (numbered 110 and higher). Unless the student has placed out of some of them, these must include Math 110, 120, and 151 (the basic courses in analysis, algebra, and geometry) and at least two terms of discrete mathematics. Reading and/or research courses may only be included in this 135 units if approved by the executive officer for mathematics. Special Regulations for Graduate Options 461 462 The general Institute requirements specify that the recipient of a master's degree must have taken at least 135 units of graduate work as a graduate student at the Institute, including at least 81 units of advanced graduate work in mathematics. This advanced work is interpreted as work with a course number greater than 109 and may include a master's thesis. Ma Degree of Doctor of Philosophy Course Program The graduate courses are listed in section five. The three core course series— Ma 110 abc in analysis, Ma 120 abc in algebra, and Ma 151 abc in geometry and topology - are required of all graduate students. Students are expected to complete each of the core course series during the first year of study, unless they complete the corresponding qualifying exam upon entrance to the program (see section on qualifying exams). In addition, students are required to complete nine quarters of other advanced mathematics courses Ma 111 and above, at least two of which are in discrete mathematics: combinatorics, complexity, and computability, or logic and set theory. Unless these nine course quarters are given pass/ fail only, they must be taken for grades. Reading and research do not normally qualify to meet these requirements. Under special circumstances (e.g., finishing the degree in three years), exceptions to these requirements may be considered by the graduate option representative. Beginning no later than the second year, students will be expected to begin independent research work and will be strongly encouraged to participate in seminars. Qualifying Examinations Qualifying examinations in the three core areas - analysis, algebra, and geometry/topology - emphasize mastery of the basic concepts and theorems and the ability to apply them to specific cases. Students are required to take and pass two of the three examinations, and for the third not taken, students must earn a B or better in all three terms of the corresponding course series. The exams are offered at the beginning of the Fall term and end of the spring term each academic year, with exceptional offerings made at other times of the year if needed and approved by the graduate option representative. The examinations must be attempted by the end of the spring term during the first year of study, and completed by the end of the first academic year. Entering students are permitted to take one or more qualifying examinations at the beginning of the fall term of their first academic year. If completed successfully, the student may drop the corresponding core course and will be excused from the remainder of the corresponding core requirement. Special exceptions or extensions to the qualifying examination timeline may be considered by the graduate option representative with support from the primary research adviser. Information for Graduate Students Teaching Requirements Teaching is an integral part of the mathematics graduate education. It is expected that students serve as teaching assistants in each term courses are offered unless alternative arrangements have been made with the option and approved by the executive officer. Summer Study Although there are no courses given in the summer, graduate students are expected to carry out studies and research in their chosen area of mathematics. In the summer after the first year, they will work under the guidance of a faculty member to investigate a possible area for their thesis research. Thesis Advising and Tracking Committee It is expected that by the fall quarter of the second year, students will find a member of the faculty who agrees to serve as their thesis adviser. The formal change of adviser process should be complete by the end of the second academic year. The progress of all continuing students is assessed by the faculty each fall, and students will consult with their advisers about their progress and planning of their studies and research. Students receive help and advice not only from their thesis adviser and other faculty mentors, but also whenever needed from the graduate option representative and the executive officer. (See also the section with guidelines for graduate student advising.) In addition to the primary thesis adviser, each student will have a candidacy committee, Thesis Advisory Committee (TAC), and final defense committee. In most cases, the members of all of these committees are the same, but the student has the right to change the members. The student in consultation with his or her adviser will arrange the formation of the committee, which will have at least four members and meet the requirements listed in the subsection Graduate Policies and Procedure entitled 'Degree of Doctor of Philosophy.' At least two of the committee members should be members of the mathematics professorial faculty and the chair of the committees must be a professorial faculty who is not the primary research adviser. Admission to Candidacy Before the end of their third year, students are expected to finish the process of applying for admission to candidacy for the Ph.D. degree. This formal step requires completion of the qualifying examinations, core courses, and advanced courses, as well as a satisfactory oral presentation to a committee of faculty members. The presentation will describe both the general area of the student's proposed thesis research and the specific problem or problems to be addressed. The candidacy meeting should be complete by the beginning of the fourth year of study. It normally takes place during the spring term of the third year. In some cases, during the summer term of the third year, but scheduling must be done by the end of the spring term. Special exceptions or extensions to the admission to candidacy timeline may be considered by the graduate option representative with support Special Regulations for Graduate Options 463 464 from the primary research adviser. Thesis Advisory Committee Meetings The Thesis Advisory Committee (TAC) will track the student's progress through annual meetings between the candidacy exam and final defense. It is the responsibility of the student to convene the TAC during the fourth and fifth year of study. The fourth-year meeting should take place no later than the end of the winter term of the fourth year. The fifth-year meeting should take place no later than the end of the fall term of the fifth year. Thesis and Final Examination At least two weeks prior to the final thesis defense, candidates for the degree of Doctor of Philosophy must deliver copies of their theses to their advisers, to the Graduate Office, and to the members of the committee that will conduct the final oral examination on the thesis. The examination must be held at least three weeks before the date on which the degree will be conferred and at least two weeks after the delivery of the copies of the thesis. Ma Subject Minor Students majoring in other fields may take a subject minor in mathematics. Minor programs must include 54 units of advanced work approved by a representative of the mathematics department, who will ensure that the work represents a concentrated study in one or more of the main fields of mathematics. A special oral examination in the subject minor will be given soon after completion of the minor program. MECHANICAL ENGINEERING (ME) Aims and Scope of the Graduate Program Mechanical engineering (ME) research and study are offered through the Department of Mechanical and Civil Engineering (MCE). The degrees of Doctor of Philosophy (Ph.D.) and Master of Science (M.S.) are offered. In general, students who intend to work full-time toward the Ph.D. degree as a final degree objective are admitted to the Mechanical Engineering Graduate Program. The M.S. degree is typically only awarded to students who pursue the Ph.D. degree in mechanical engineering at Caltech and who do not already have an M.S. degree in mechanical engineering. The aim of the graduate program in mechanical engineering at Caltech is to prepare students for research and professional practice in an era of rapidly advancing interdisciplinary technology. The program combines individual depth of experience and competence in a particular chosen major specialty, with a strong background in the basic and engineering sciences. It strives to develop professional independence, creativity, leadership, and the capacity for continuing professional and intellectual growth. Information for Graduate Students ME Preparation for the Graduate Program Entering graduate students are expected to have a thorough background in undergraduate mathematics, physics, and engineering. While a strong undergraduate program in mechanical engineering should provide a suitable preparation, students who have not specialized in mechanical engineering as undergraduates may also be admitted for graduate study. For example, an outstanding four-year undergraduate program in mathematics and sciences may provide a suitable background as well. The qualifications of each applicant will be considered individually, and, after being enrolled, the student will arrange their program in consultation with a member of the faculty. ME Master's Degree The degree of Master of Science in mechanical engineering is only awarded to students who do not already have an M.S. degree in mechanical engineering. The degree will be awarded upon request by students who have fulfilled the requirements. Only in exceptional cases is there admission to the M.S. program as the final degree objective. A minimum of 138 units of courses numbered 100 or above, which meet the required master's program listed below, must be passed with a grade of at least C for completion of the master's degree in mechanical engineering. All units must be taken for grades, except for courses offered only on a pass/fail basis. The M.S. degree in mechanical engineering is typically completed within the first two years of residency at Caltech.

MEDICAL ENGINEERING (MEDE) Aims and Scope of the Graduate Program The Andrew and Peggy Cherng Department of Medical Engineering offers a program of study that leads to the Ph.D. The medical engineering option at Caltech is designed for students with an engineering background who are interested in applications of micro-/nanoscale science and technology in medicine, which forms the core of Caltech's multidisciplinary medical engineering. The program's goal is to close the gap between engineering and medicine. Our medical engineering research and education leverage Caltech's strengths in engineering, applied science, and other fundamental fields, to apply emerging technological advances to medicine, and to create innovative diagnostic, monitoring, and therapeutic systems. Our major areas of research include micro/nano medical technologies and devices, medical nanoelectronics, biomedical materials and biomechanics, fluidics and bioinspired design, and medical imaging and sensing. The Degree of Doctor of Philosophy offers two tracks: MedE only and Medical and Information for Graduate Students Electrical Engineering (Med-EE). The Med-EE track is offered jointly by both departments of Medical Engineering and Electrical Engineering (see EE Section), available to any students to graduate after Fall 2022; the single degree to be shown on the diploma is "Ph.D. in Medical and Electrical Engineering". MedE Master's Degree Students are not normally admitted to work towards the M.S. degree. However, the M.S. degree may be awarded to a student along the way toward a Ph.D. degree, provided Institute and Option requirements are met. The Option requirements for the MS degree are the same as those for the Ph.D. degree except that the MS degree does not require research units, qualifying exam, candidacy exam, and thesis defense.

MedE Subject Minor A subject minor is not required, but recommended, for the Ph.D. degree in medical engineering. However, credits from the subject minor cannot be double-counted for the core program. Students may choose their original engineering disciplines as their minor subjects. Students are not allowed to choose medical engineering as a subject NEUROBIOLOGY (NB) Aims and Scope of the Graduate Program Neurobiology-the study of the nervous system—is a highly integrative science. The modern neurobiologist must be conversant with concepts from molecular biology, cell and developmental biology, systems neuroscience, animal behavior, and mathematical modeling. The aim of the graduate program is to expose each student to this breadth of the discipline. To accomplish this, we offer a first-year curriculum with requirements in specified areas, along with a core course that spans many subjects. Students enter neurobiology from many different disciplines, ranging from particle physics to physiology to psychology. Accordingly, each Ph.D. student is paired with a first-year adviser so the course selections can best complement the student's background. In later years, the student's focus is on original research in a chosen specialty. Our goal is that students will graduate with specific research accomplishments and the broad understanding required to chart their subsequent forays in brain science. Information for Graduate Students NB Admission Applicants are expected to have studied college-level mathematics, physics, chemistry, and biology. They should also have experience in independent research. Coursework in neurobiology and experience in scientific computing are helpful, but not required. Whenever possible, applicants will be interviewed on campus before final admission decisions are made. NB Master's Degree The option does not admit students for work toward the master's degree. A terminal M.S. may be awarded in exceptional circumstances. NB Degree of Doctor of Philosophy First-year adviser Each incoming student is paired with an academic adviser during the first year. This mentor will guide the student in course selection and other decisions, taking the student's background into account. Where possible, this adviser will not be one of the prospective rotation supervisors. Rotations First-year students carry out three laboratory rotations, each lasting one quarter. At least two of these should be with faculty participating in the option. By June 30 of the first year, students choose a Ph.D. adviser. Formal Classes Students take at least 6 quarter courses (54 units) as follows: 1. Bi/CNS/NB 164, Tools of Neurobiology 2. Bi 252, Responsible Conduct of Research 3. One course in molecular, cellular, developmental neurobiology 4. One course in circuits, systems, behavioral biology 5. One course in mathematical methods (depending on the student's background) 6. Two electives For a list of courses in subject areas 3-5, see the option website. All courses must be taken for a grade unless only offered pass/fail. Teaching All students are to serve as teaching assistants for at least two terms. Admission to Candidacy To qualify for candidacy, the student must first demonstrate broad competence by passing each of the first-year courses with a grade of B or higher. Failure here can be remedied by successful second-year coursework. By June 30 of the second year, the student must also defend a thesis proposal in an oral exam before a qualifying exam Special Regulations for Graduate Options 473 474 committee of at least three faculty. This exam will also cover general knowledge in the relevant field. With special permission, the oral exam may be retaken once before the end of winter quarter of the third year. Students that do not advance to candidacy by the end of the third year may not continue in the program. Thesis Advisory Committee Once admitted to candidacy, the student chooses a Thesis Advisory Committee of at least three faculty. This committee serves as a source of advice independent of the Ph.D. adviser throughout the student's tenure. Each year, before the end of June, the student delivers a written progress report, followed by a meeting with the Thesis Advisory Committee. Thesis Examination Committee This committee should consist of a minimum of four voting members, three of whom must be Caltech faculty. The final oral examination covers principally the work of the thesis, and according to Institute regulations must be held at least three weeks before the degree is to be conferred. PHYSICS (PH) Aims and Scope of the Graduate Program The physics option offers a program leading to the degree of Doctor of Philosophy. This program prepares students for careers in scientific research or research combined with teaching, and so its most important part is independent research. Courses are offered that give a broad treatment of both fundamental physics and specialized physics research topics. These are intended both to help a beginning graduate student prepare for research and to broaden an advanced student's knowledge of physics. Caltech research opportunities include elementary particle physics, nuclear physics, cosmic-ray, gamma-ray, and X-ray astronomy, submillimeter astronomy, condensed-matter physics, atomic/molecular/optical physics, quantum information, applied physics, gravitational physics, cosmology, astrophysics, mathematical physics, biophysics, and theoretical physics. A Master of Science degree may be awarded upon completion of a program of courses. Students are not normally admitted to work toward the M.S. in physics unless they are also working toward a Ph.D. Admission The application submission deadline for physics is December 15. The admission process follows Institute regulations. The GRE tests (general and advanced subject) are not required and scores will not be considered for admission. Information for Graduate Students Ph 125 abc 27 units (If this course, or its equivalent, was taken as part of an undergraduate program, it may be replaced by 27 units of any quantum-mechanics-based course.) Physics electives 81 units These must be selected from physics courses numbered 100 and above. Other electives 27 units These must be graduate courses from any option at Caltech. Ph Master's Degree A Master of Science degree in physics will be awarded, upon request, to physics Ph.D. students who have completed the oral and written candidacy examinations. Alternatively, a master's degree will be awarded to any Caltech graduate student in good standing upon satisfactory completion of a program approved by the option representative that fulfills the following requirements: Substitutions of other graduate courses in place of the above requirements must be approved by the option representative. In exceptional cases, undergraduate students may receive concurrent B.S./M.S. degrees if the above requirements are met in addition to the relevant B.S. requirements, upon approval from the Physics Graduate Committee, the graduate admissions committee, and the physics executive officer. Such students must produce a detailed petition demonstrating accomplishments that would warrant normal admission to the physics graduate program. Ph Degree of Doctor of Philosophy In addition to the general Institute requirements for a Ph.D., the particular requirements for a doctorate in physics include admission to candidacy as described below, writing a thesis that describes the results of independent research, and passing a final oral examination based on this thesis and research. Physics graduate students may exercise the pass/fail option on any and all courses taken. Advising structure and thesis supervision An academic adviser is appointed for each student upon admission to the graduate program in physics. The academic adviser will serve as the primary mentor until the student finds a research adviser. Students will meet with their academic adviser to decide on their first-year course schedule, and are encouraged to continue these meetings quarterly until the student finds a research adviser. During the first year Special Regulations for Graduate Options 475 476 of study, students should consult with their academic adviser, the option representative, the executive officer, and/or individual faculty members to select a tentative research group. Once a research adviser is selected students may either replace the originally appointed academic adviser or maintain both a research adviser and academic adviser. At any time, a student may consult with the option representative concerning such matters as advising. Students should consult with the executive officer to assemble their oral candidacy committee and Thesis Advisory Committee (TAC) by the end of their third year. The TAC is normally constituted from the candidacy examiners, but students may propose variations or changes at any time to the option representative. The TAC chair is normally someone other than the research adviser. The TAC chair will typically also serve as the thesis defense chair, but changes may be made in consultation with the executive officer for physics and the option representative. The candidacy committee will examine the student's knowledge of his or her chosen field and will consider the appropriateness and scope of the proposed thesis research during the oral candidacy exam. This exam represents the formal commitment of both student and adviser to a research program. After the oral candidacy exam, students will hold annual meetings with the TAC. The TAC will review the research progress and provide feedback and guidance towards completion of the degree. The TAC, research, and/or academic advisers provide the majority of mentoring to the student. In addition, the option representative and other members of the faculty are always available to provide advice and mentoring on any aspect of research, progress toward the Ph.D., future careers, and other aspects of life in graduate school. Basic Physics Requirement Physics students must demonstrate proficiency in all areas of basic physics, including classical mechanics (including continuum mechanics), electricity and magnetism, quantum mechanics, statistical physics, optics, basic mathematical methods of physics, and the physical origin of everyday phenomena. A solid understanding of these fundamental areas of physics is considered essential and proficiency will be tested by two written candidacy examinations. No specific course work is required for the basic physics requirement, but some students may benefit from taking several of the basic graduate courses, such as Ph 106, Ph 125, and Ph 127. A syllabus describing the exam contents will be available, and students are encouraged to study independently for the exams, rather than taking a heavy load of basic physics courses. In addition, the class Ph 201 will provide additional problem solving training that matches the basic physics requirement. The written exams are typically offered in July and in October, and the two separate exams may be taken at different times. This flexible scheduling of the written exams allows students to prepare for the exams while simultaneously learning about research areas, either through advanced courses, reading courses, or participation in a Information for Graduate Students research group. The exams can be attempted up to three times and must be successfully completed by the end of the second year of study. Advanced Physics Requirement In addition to demonstrating a proficiency in basic physics, students must also establish a broad understanding of modern physics through study in six graduate courses. The courses must be spread over at least three of the following four areas of advanced physics: 1. Physics of elementary particles and fields: Nuclear physics, high-energy physics, string theory 2. Quantum information and matter: Atomic/molecular/optical physics, condensed-matter physics, quantum information 3. Physics of the universe: Gravitational physics, astrophysics, cosmology 4. Interdisciplinary physics: e.g., Biophysics, applied physics, chemical physics, mathematical physics, experimental physics Each area is meant to be covered by the equivalent of a one-term course, and a list of example courses for each of the areas can be found at the physics option website. Other courses may be substituted with permission of the physics option representative. Oral Candidacy Exam This exam is primarily a test of the candidate's suitability for research in his or her chosen field. The professor with whom the student plans to do research will be a member of the exam committee, and normally the student will have already begun research (Ph 172) on a definite topic with that professor. The examination will cover the student's research work and its relation to the general field of specialization. Before being allowed to take this exam, a student must have satisfied all the other requirements for admission to candidacy. The oral candidacy exam should be completed by the end of the third year (12 term) of graduate residence. Admission to Candidacy To be recommended for Ph.D. candidacy, a student must pass two terms of Physics Seminar (Ph 242), satisfy the Basic Physics Requirement by passing the written candidacy examinations, satisfy the Advanced Physics requirements, and pass the Oral Candidacy Examination. These requirements are designed to ensure that students have an adequate preparation in the basic tools of physics, as well as a broad general knowledge of advanced physics. Special Regulations for Graduate Options 477 478 Research Requirements There are no specific research requirements, but in general a substantial effort is required to master the techniques in a given field and carry out a significant piece of original research. Students are strongly advised to start doing part-time research as soon as possible by taking reading and research units (Ph 171-172) in parallel with formal coursework. Teaching Requirement It is expected that each graduate student will, as part of the Ph.D. graduation requirements, serve as a teaching assistant for at least one term, an experience that most students find provides valuable experience for their future careers. Students are encouraged to fulfill this requirement within the first three years of residency. Thesis and Final Examination A final oral examination will be given not less than two weeks after the thesis has been presented in final form. This examination will cover the thesis topic and its relation to the general body of knowledge of physics. The candidate is responsible for completing the thesis early enough to allow the fulfillment of all division and Institute requirements, with due regard for possible scheduling conflicts. Degree progress timeline The following timeline is required for satisfactory degree progress: 1. Ph 242 should be taken by all students in their first year of graduate study. 2. The written candidacy exams should be attempted by the end of a student's first year of graduate residence, and be passed by the end of the second year. 3. The Advanced Physics requirement should be completed by the end of the second year of graduate residence, but may be extended into the third year depending on the availability of specific courses. 4. The oral candidacy exam must be completed by the end of the third year (12th term) of graduate residence. The Minor A minor is not required, but a student may elect to pursue a minor in another option. Language Requirements There are no language requirements for a Ph.D. in physics. Ph Subject Minor Students desiring a subject minor in physics should discuss their proposed program with the chair of the Physics Graduate Committee. Forty-five units from physics courses with numbers over 100 must be taken for the subject minor, excluding Ph 129 and any specific courses in physics required for the student's major program. An oral exam may be required by the Physics Graduate Committee. This exam Information for Graduate Students will include both academic topics and topics on current physics research areas. QUANTUM SCIENCE AND ENGINEERING (QSE) Quantum science and engineering (QSE) may be pursued as a subject minor by graduate students who are pursuing Ph.D. degrees in any option. The QSE minor is intended to supplement one of Caltech's graduate degrees and is designed for students who wish to broaden their knowledge of QSE beyond their major field of study. The QSE minor is also intended to recognize graduate students' interest in and dedication to QSE as demonstrated by the successful completion of a program of study in the field. Completion of the QSE minor program of study will be recognized on the Ph.D. diploma by the statement, "...and by additional studies constituting a minor in Quantum Science and Engineering." Requirements To receive the QSE minor, graduate students must fulfill the following requirements: • APh/Ph 138ab • 18 units (two terms) from the following list: APh/EE 190abc, CS/Ph 120, EE/APh 158, Ph 137ab, Ph/CS 219abc, Ph/APh 223ab, Aph 150 (special topics class when topic is relevant to QSE, in consultation with the oversight committee), Ph177 (relevant QSE topic must be chosen in consultation with oversight committee). Other courses relevant to QSE can be included in consultation with the oversight committee. All courses to be applied toward the QSE minor requirements must be taken on a graded basis unless only offered as pass/fail. Students must obtain a grade of B- or higher in all courses taken on grades and a pass in courses taken as pass/fail. At least 18 units of courses that are used to satisfy the QSE minor cannot be used to satisfy course requirements in the major options unless absolutely required by the option. Courses taken as part of the QSE minor are counted toward the total number of units required for the completion of the Ph.D. degree. QSE Minor Administration The QSE minor is administered by an oversight committee consisting of faculty members reporting to the chair of the engineering and applied science division. In consultation with their advisers and, if needed, with the QSE Oversight Committee, students formulate a program of approved courses individually tailored to each student's background and needs, with the objective that the student achieve a level of competence in specific subjects relevant to QSE. Students must petition the QSE Oversight Committee for approval of their program of study. Upon completion of the program of study, the QSE Oversight Committee will verify that the QSE minor requirements have been fulfilled.

Second-year courses provide additional training in In the fall quarter, all second-year students are required to enroll in SS 224 and at least 27 additional units of advanced social science courses. In the winter quarter, all second-year students are required to enroll in 36 units of advanced social science courses. In the spring quarter, second year students must enroll in at least 27 units of advanced social science courses (three typical courses) and enroll in 9 units of Research in Social Science (SS 300) to work on their second-year paper, for the units remaining to reach 36 units Appropriate courses in other options, such as mathematics and computer science, can be substituted for advanced social science classes, with the permission of the HSS division's option representative. All classes offered for grades must be completed with a grade of B or better. Students may take independent reading and study courses, but during the second year such courses do not count toward the above requirements. Students can tailor their second-year curriculum to their specific research interests but are expected to include at least two second-year course sequences. Such course sequences include Foundations of Political Economy (SS 210abc), Advanced Economic Theory (SS 211 abc), Experimental Economics (SS 212abc), Financial Economics (SS 213abc), Topics in Theoretical and Applied Econometrics (SS 223abc), Applied Empirical Methods in the Social Sciences (SS 228abc), Theoretical and Quantitative Dimensions of Historical Development (SS 229abc), American and Comparative Politics (SS 231abc), and Experimental Methods of Political Economy (SS 260). Students may partially fulfill the second-year sequence requirement by taking a sequence of courses in mathematics, such as Ma 108abc, Ma 110abc, Ma/ACM/IDS 140ab, or Ec 181 ab. Third year. Beginning in their third year, and in all subsequent years, all students must enroll in the 3-unit graduate student pro-seminar (SS 282abc) every quarter. Every student must make a presentation in this class at least once a year. Students in the third year may also enroll in Special Regulations for Graduate Options 483 484 additional courses, with the approval of their adviser. Third year students are required to take SS 281 in the fall quarter. In each quarter, third year students should enroll in Research in Social Science (SS 300) for the units remaining to reach 36 units. Fourth and fifth years. Students need to register for 33 units of SS 300 and 3 units of the graduate student pro-seminar (SS 282abc). Progress in the program, and advancement to candidacy In addition to the coursework and examinations described above, students must enroll in at least 36 units every quarter, including summer (SS 300) and complete the following requirements. By May 1 of the second year, each second-year student must submit an outline describing a planned paper to their paper adviser, their second reader, and the option representative. The second-year paper can be co-authored. If the co-author is another graduate student, only one of the students on the joint project can use the paper to fulfill the requirement. The person using the paper for fulfilling the requirement is expected to do most of the actual writing of the paper that is sub-mitted. The final paper is due on September 15. If the paper adviser and the second reader both find that a student's second-year paper is satisfactory, the student advances to the third year. If they do not, the social science faculty, as a whole, will review the student's paper. If they decide that the paper is not satisfactory, they may terminate the student from the program. At the end of the second year, the social science faculty will also meet and assess each second-year student's ability for clear self-expression in both oral and written English. In case of language deficiencies, the student is required to take and pass a remedial English class, SS 299, during the summer quarter. Also, starting their second year, students are expected to TA a minimum of three quarters total during their graduate career. Third-year students must write a research paper and present it to the faculty before the start of the fourth year. The third-year paper cannot be co-authored but should be worked on in consultation with and under the direction of the student's primary adviser. The option representative will appoint a second third-year paper reader, who must be a member of the social sciences professorial faculty. The adviser and second reader will monitor progress and advise the student on the third-year paper. The paper and the presentation must demonstrate to the faculty that the student is capable of undertaking original research and presenting it to a scholarly audience. After completion of the third-year paper presentation, the social science faculty evaluates the student's overall performance and research potential. This review is based primarily upon the third-year paper, but the faculty also verifies that the student has satisfactorily completed all previous requirements. If this evaluation is favorable, the student is admitted to candidacy for the Ph.D. If the faculty evaluation is unfavorable, the student may be terminated from the program. Information for Graduate Students Organization of Thesis Committee By October 1 of the third year, each student selects a primary adviser. The adviser must be a professorial member of the social science faculty at Caltech. It is possible to change advisers, in consultation with the option representative, if a student's research interests change. Students, in consultation with their adviser, must select two additional thesis committee members after the student has advanced to candidacy (normally by the beginning of their fourth year). After a student advances to candidacy, the division chairperson, in consultation with the option representative, shall select a fourth member of the committee with an eye to representing the diverse interests of the social science faculty. One of the four members of the thesis committee may be emeritus faculty, research faculty, or an external scholar, with the approval of the option representative and the dean of graduate studies. The chair of the thesis committee must be someone other than the primary adviser, who will be appointed by the social science option representative in consultation with the primary adviser. The thesis committee will also serve as the examination committee at the thesis defense. SS Degree of Doctor of Philosophy By November 1 of their fourth year, students must complete a dissertation prospectus that outlines the proposed dissertation work and present a tentative schedule detailing when the components of the dissertation are to be completed. The prospectus must clearly identify a project, or dissertation components, that should culminate in a job market paper at the beginning of the student's fifth year (August before the start of the fifth year, in the case of students who seek a position in political science). The prospectus must be submitted to and approved by the thesis committee by November 1, and the status communicated by the principal adviser to the option representative. By May 1 of the fourth year, the student is required to convene a thesis prospectus seminar with their thesis committee. In this seminar, the student is to report on the current status of their dissertation research and outline a plan and timeline for completing it. The seminar must be based on the student's planned job market paper, and a draft of this paper must accompany the proposal. The student and the the-sis committee should reach a clear, mutual under-standing as to what additional work needs to be done to complete and to successfully defend their dissertation. After the dissertation is completed, the student, in consultation with their adviser, must schedule an oral thesis examination to defend their dissertation. The student must provide a written copy of their dissertation to the option representative and all members of the examination committee, and complete the examination notification in Regis, not less than two weeks prior to the thesis examination date. The dissertation is expected to represent publishable, original research.

Noise and Stochastic Resonance. 9 units (3-0-6); second, third terms. Prerequisites: Ph 12 abc, ACM 95/100 ab and Ph 106 abc, equivalent background, or instructor's permission. The presence of noise in experimental systems is often regarded as a nuisance since it diminishes the signal to noise ratio thereby obfuscating weak signals or patterns. From a theoretical perspective, noise is also problematic since its influence cannot be elicited from deterministic equations but requires stochastic-based modeling which incorporates various types of noise and correlation functions. In general, extraction of embedded information requires that a threshold be overcome in order to outweigh concealment by noise. However, even below threshold, it has been demonstrated in numerous systems that external forcing coupled with noise can actually boost very weak signatures beyond threshold by a phenomenon known as stochastic resonance. Although it was originally demonstrated in nonlinear systems, more recent studies have revealed this phenomenon can occur in linear systems subject, for example, to color-based noise. Techniques for optimizing stochastic resonance are now revolutionizing modeling and measurement theory in many fields ranging from nonlinear optics and electrical systems to Applied Physics 509 510 condensed matter physics, neurophysiology, hydrodynamics, climate research and even finance. This course will be conducted in survey and seminar style and is expected to appeal to theorists and experimentalists alike.

BEM 117. Behavioral Finance. 9 units (3-0-6); third term. Prerequisites: Students are recommended (but not required) to take BEM 103 to become familiar with some basic concepts in finance. Much of modern financial economics works with models in which agents are fully rational, in that they maximize expected utility and use Bayes' law to update their beliefs. Behavioral finance is a large and active field that develops and studies models in which some agents are less than fully rational. Such models have two building blocks: limits to arbitrage, which makes it difficult for rational traders to undo the dislocations caused by less rational traders; and psychology, which provides guidance for the kinds of deviations from full rationality we might expect to see. We discuss these two topics and consider a number of applications: asset pricing; individual trading behavior; the origin of bubbles; and financial crises. Not offered 2022-23. BEM/Ec/ESE 119.

This course offers instruction in writing and speaking about science and technology for non-expert audiences. Instruction focuses on how to convey complex technical information in clear, engaging prose and speech in a variety of contexts. Readings in different genres (e.g., the newspaper discovery story, the op-ed, the personal narrative, the English 613 614 explainer talk) raise issues for discussion and serve as models for assignments in these genres. The workshop-style nature of this course relies on drafting and revision in response to peer and instructor feedback. Satisfies the Institute scientific writing requirement and the option oral communications requirement for humanities majors. Instructor: Hall. En 85. Poetry Writing. 9 units (3-0-6); third term. When William Blake wrote "to see a World in a Grain of Sand," he tapped into poetry's power to model the universe. For instance, once we set up a simile between "world" and "grain of sand", we can test this hypothesis of sameness. How is sand like the world? Where will the model fail? And what might that tell us? Imagery, sensory language, arguments, ideas, and verse form itself can lead poetry toward power and discovery. This pursuit can reach from the page into one's own life. We will work hard together on poems, our own and one another's. Instructor: Factor. En 86. Fiction Writing. 9 units (3-0-6); second term. The class is conducted as a workshop of fiction writing. Contemporary short stories and novel excerpts are discussed, as well as the art and craft of writing well. The course covers the essential elements of fiction writing, including character, voice, setting, world building, scene, summary, plot, and dialogue. Each week, we discuss a particular craft element, analyze published fiction, and provide feedback on student writing. Near the end of the course, students critique the work of their peers in small-group workshops. Instructor: Lepucki. En 89. Journalism and Storytelling. 9 units (3-0-6); third term. Today's political and social turmoil have cast a sometimes harsh light on news media and the journalistic writing approach. Is the media fulfilling its role in our democracy? What should it be? And what approach should journalists take in their reporting and writing? This course will ponder these questions as it explores how to construct interesting, relevant, journalistic storytelling, including the use of new media tools. It will emphasize the foundations of the craft, such as close attention to fact, accuracy, clarity and precision, and examine its critical components, such as story form, reporting and interviewing, theme and scene, and character development. It will offer opportunities to construct a long-form journalistic piece. Students will produce numerous stories and other writing during the class, including profiles, issues, analysis and reviews. Several of these will be offered for publication in The California Tech. There will be class visits by professional journalists and a possible off-campus excursion. Instructor: Kipling. En 98.

Instructor: Staff. En 100. Artificial Life: Literary Automata. 9 units (3-0-6); third term. Well before the advent of the Machine Age, literary texts have been populated by various kinds of ingenious automata, often in animal or human form. This course surveys the role of the automaton in literary texts in order to consider how the notion of "artificial life" changes over time, with a focus on the special case of the human machine. Readings from the eighteenth and nineteenth centuries to include texts by la Mettrie, Hoffmann, Kleist, Shelley, Poe, and de l'Isle-Adam. We will conclude with a classic text from the twentieth century: Isaac Asimov's 1, Robot.. Instructor: Holland. En 101. Recalling the Wild. 9 units (3-0-6); second term. City-dwellers invented the concept of wilderness, as a space apart from human laws and culture. This course takes a critical look at the different values attributed to that space as it has been colonized by the human imagination. Our discussions will focus on the emergence of the perception of wilderness in European literature in the eighteenth and nineteenth centuries, but we conclude with the question: what meaning do we invest the concept of "wilderness" with today? Readings will include works by Buffon, Toqueville, Chateaubriand, Byron, Thoreau, Wells, and London. Instructor: Holland. En 103. Introduction to Medieval British Literature. 9 units (3-0-6); first term. This course offers a tour of major (as well as some minor) genres and works written in Britain prior to 1500. Far from a literary "dark age," the Middle Ages fostered dramatic experiments in narrative form, bequeathing to modern literature some of its best-loved genres and texts. We will practice reading in Middle English-the language of Chaucer and his contemporaries-while we concentrate on the following questions: how did these texts circulate among readers? How do they establish their authority? What kinds of historical and cultural currents to they engage? Texts may include the lives of saints, the confessions of sinners, drama, lyrics, romances, selections from Chaucer's Canterbury Tales, and Malory's Morte Darthur. Readings will be in Middle and modern English. Not offered 2022-23. En 104. Imagining the Medieval in the Nineteenth Century. 9 units (3-0-6); third term. Following the Enlightenment and amidst the Industrial Revolution, the late-eighteenth and nineteenth centuries saw a surging interest in the literature, lives, art, and architecture of the Middle Ages. In this course, we will explore how authors represented, invoked, and often idealized the medieval past-with its knights, peasants, saints, and monsters-as a way to think through the challenges-social, literary, political, aesthetic-of their own time. We will read several novels, poems, and treatises, including Henry David Thoreau's essay, "Walking;" Mark Twain's A Connecticut Yankee in King Arthur's Court; Alfred Lord Tennyson's Idylls of the King; and others. Requirements for the course English 615 616 will include weekly response papers and two essays. Not offered 2022-23. En 105. Old English Literature. 9 units (3-0-6); first term. "Moõõe word fræt." Want to learn how to read the riddle that begins with these words? This course will introduce students to Old English: the earliest form of the English language, spoken in England from roughly the years 450 to 1100. In studying the language, we will turn to its diverse and exciting body of literature, including one poem commemorating the brutal defeat by a Viking army and another based on the biblical story of Judith, who tricks the evil king Holofernes into sleeping with her-but not before slicing off his drunken head. We will also read a variety of shorter texts: laws, medical recipes, humorously obscene riddles. Successful completion of the course will give students a richer sense not only of the earliest period of English literature, but also of the English language as it is written and spoken today. No prior experience with Old or Middle English is necessary for this course. Not offered 2022-23. En 106. Poetry and the Project of Justice. 9 units (3-0-6); third term. This course explores how contemporary poets grapple with the most urgent questions of our moment: identity, equality, environmental crisis, and justice. In this class, students will gain confidence in reading, discussing, and writing about contemporary poems and will encounter recent and more distant traditions of protest poetry. We will ask how poetic language articulates questions of embodiment, community, law, and memory. The syllabus will focus in particular on writers of color, including queer and indigenous poets, and will include opportunities to attend local poetry readings. Instructor: Jahner. En 107. Medieval Romance. 9 units (3-0-6); third term. The medieval term romanz designated both a language, French, and a genre, romance, dedicated to the adventures of knights and ladies and the villains, monsters, magic, and miles that stood in their way. This course explores key examples from the twelfth through the fifteenth centuries, while also examining evolutions in the form. We will consider how romances figured love and desire as well as negotiated questions of law, territory, and cultural difference. Authors and texts may include Chretien de Troyes, Marie de France, Gawain and the Green Knight, Arthurian legends, outlaw tales, and hagiography. Not offered 2022-23. Instructor: Jahner. En 109. Madness and Reason. 9 units (3-0-6); second term. Madness threatens to dissolve boundaries of the most various kinds: between the human and the inhumane, reality and fantasy, sickness and health. One of the tasks of a literary text is to subdue and contain madness through the construction of rational frameworks. How does a literary text accomplish this? Which strategies, such as the use of irony and humor, are the most effective? What role do insane characters play in literary texts? And when - if ever - should we consider an excess of reason as a kind of madness in its own right? Selected readings from Shakespeare, Voltaire, Goethe, Hoffmann, Büchner, Gogol, and Schnitzler, among Courses others. Not offered 2022-23. Instructor: Holland. En/VC 110. Sinners, Saints, and Sexuality in Premodern Literature. 9 units (3-0-6); first term. This class explores the history of sexuality and gender across the Middle Ages and Renaissance. Exploring both literary texts and visual representation, it considers how previous eras and cultures understood embodiment, sexuality, and gender and asks how we, as modern readers and viewers, approach these questions across the distance of centuries. We will read across a wide range of literature, including theology, philosophy, fiction, romance, and spiritual biography, and examine manuscript illustrations and other early visual media. Questions we will take up include the following: how did writers and artists construct the "naturalness" or "unnaturalness" of particular bodies and bodily acts? How did individuals understand the relationship between their own bodies and those of others? In what ways did writing and art authorize, scrutinize, or otherwise parse the boundaries of the licit and illicit? Finally, how have modern critics framed these questions? How do we approach and make use of earlier theories of sex and gender? Not offered 2022-23. Instructor: Jahner. En 112. Nineteenth-Century American Poetry. 9 units (3-0-6); third term. In the 1855 edition of Leaves of Grass, Walt Whitman claimed that "the United States themselves are essentially the greatest poem." We might ask any number of questions in response to Whitman. If the United States are a poem, then who wrote it? What is this poem about? What genre is it? Is anyone reading it? Is it actually any good? Though we might approach Whitman's statement with some apprehension from our historical moment, this course will take seriously American life lived within poetry and the lives poems lived across the country. Together, we will track the development of American poetry as it engages with enslavement, abolition, genocide, war, beauty, nature, racialization, constructions of gender, sexuality, and affect. Ultimately, we will ask what reading nineteenth-century American poetry, or nineteenth-century America as a poem, might mean for our understanding of the country today. Readings may include Bryant, Poe, Longfellow, Schoolcraft (Bamewawagezhikaquay), Whitman, Dickinson, Harper, Dunbar, and Noguchi. Instructor: Hill. En 113. Shakespeare's Career: Comedies and Histories. 9 units (3-0-6); second term. The first of a two-course sequence on Shakespeare's career as a dramatist and poet. We will read plays from the first half of Shakespeare's career, his comedies and histories. Particular attention will be paid to Shakespeare's use of his sources and to the textual history of the plays. En 113 and En 114 may be taken independently and, usually, are given in alternate years. Not offered 2022-23. Instructor: Pigman. En 114. Shakespeare's Career: Tragedies and Tragicomedies. 9 units (3-0-6); third term. The second of a two-course sequence on Shakespeare's career as a dramatist and poet. We will read works from the second half of Shakespeare's career, his tragedies, tragicomedies, English 617 618 and Sonnets. Particular attention will be paid to Shakespeare's use of his sources and to the textual history of the plays. En 113 and En 114 may be taken independently and, usually, are given in alternate years. Not offered 2022-23. Instructor: Pigman. En 115. The Women of Ancient Epic. (3-0-6); second term. Epic remains the most ancient and most modern of literary genres. Women in ancient epic begin as prizes of honor for male warriors and become powerful witches and queens, while some contemporary women writers allow their ancient heroines to speak in their own voices. From Homer to the present, epic narratives also traverse continents as they narrate the founding and foundering of empires historical and imaginary. This course introduces students to key classical epics while exploring historical and contemporary adaptations from Dante's Divine Comedy to Madeline Miller's Circe. By examining the afterlives of epic, we will consider how the genre changes when taken up by the gender typically marginalized in the classical tradition. Possible authors include Homer, Apollonius of Rhodes, Virgil, Ovid, Dante, Christa Wolf, Ursula K. Le Guin, Madeline Miller, and María Baranda. Instructors: Jahner, Pigman. En 118. Classical Mythology. 9 units (3-0-6); second term. Why did the Greeks and Romans remain fascinated with the same stories of gods and demigods for more than a thousand years? On the other hand, how did they adapt those stories to fit new times and places? Starting with the earliest Greek poems and advancing through classical Athens, Hellenistic Alexandria, and Augustan Rome, we consider the history of writing poetry as a history of reading the past; the course also serves as an excellent introduction to ancient literary history at large. Readings may include Homer's 'Odyssey,' Hesiod, Aeschylus, Euripides, Apollonius Rhodius, Ovid, and Seneca. Instructor: Haugen. En 119. Displacement. 9 units (3-0-6); first term. We read three famous novels about people who migrate and people who immigrate, by authors who have also been uprooted in their own lives: Salman Rushdie's 'Midnight's Children' (1981), Zadie Smith's 'White Teeth' (2000), and Jonathan Franzen's 'The Corrections' (2001). As you can see from these dates, this class will also teach you about experimental fiction in the 20th century, a time that prized complexity and even difficulty. We won't find "linear narratives," "well-rounded characters," or "relatability" here. How are these novels structured instead? Do their experimental structures reflect the theme of displacement itself? Should we even try to generalize about a literature of displacement, and, if yes, what kinds of comparisons can we draw? Not offered 2022-23. Instructor: Haugen. En 120. What Women Want: Desire and the Modern American Novel. 9 units (3-0-6); second term. The question of what a woman wants animates a central strain of the modern American novel, as do evolving ideas about what women can and cannot have. This course considers female desire-for personal agency and freedom, self- and sexual fulfillment, economic and social opportunity-across a half dozen novels written from about 1880 - 1940, in light of some of the cultural forces Courses that shape and constrain characters' (and real women's) horizons. Authors covered may include Henry James, Edith Wharton, Theodore Dreiser, Anzia Yezierska, Nella Larsen, and Zora Neale Hurston. Not offered 2022-23. Instructor: Jurca. En 123. The 19th-Century English Novel. 9 units (3-0-6); third term. A survey of the 19th-century novel from Austen through Conrad, with special emphasis upon the Victorians.

Major authors may include Conrad, Joyce, Woolf, Forster, Lawrence, Orwell, Amis, Lessing, Rushdie. Not offered 2022-23. En 125. British Romantic Literature. 9 units (3-0-6); second term. A selective survey of English writing in the late 18th and early 19th centuries. Major authors may include Blake, Wordsworth, Coleridge, Byron, Keats, Percy Shelley, Mary Shelley, and Austen. Particular attention will be paid to intellectual and historical contexts and to new understandings of the role of literature in society. Not offered 2022-23. Instructor: Gilmartin. En 126. Gothic Fiction. 9 units (3-0-6); second term. The literature of horror, fantasy, and the supernatural, from the late 18th century to the present day. Particular attention will be paid to gothic's shifting cultural imperative, from its origins as a qualified reaction to Enlightenment rationalism, to the contemporary ghost story as an instrument of social and psychological exploration. Issues will include atmosphere and the gothic sense of space; gothic as a popular pathology; and the gendering of gothic narrative. Fiction by Walpole, Shelley, Brontë, Stoker, Poe, Wilde, Angela Carter, and Toni Morrison. Film versions of the gothic may be included. Not offered 2022-23. Instructor: Gilmartin. En 127. Jane Austen. 9 units (3-0-6); second term. This course will focus on the major novels of Jane Austen: Northanger Abbey, Sense and Sensibility, Pride and Prejudice, Mansfield Park, Emma, and Persuasion. Film and television adaptations will also be considered, and students may have the opportunity to read Austen's unfinished works, as well as related eighteenth- and nineteenth-century British fiction and non-fiction. Not offered 2022-23. Instructor: Gilmartin. En 128. Modern and Contemporary Irish Literature. 9 units (3-0-6); second term. The development of Irish fiction, poetry, and drama from the early 20th-century Irish literary renaissance, through the impact of modernism, to the Field Day movement and other contemporary developments. Topics may include the impact of political violence and national division upon the literary imagination; the use of folk and fairy-tale traditions; patterns of emigration and literary exile; the English 619 620 challenge of the English language and the relation of Irish writing to British literary tradition; and recent treatments of Irish literature in regional, postcolonial, and global terms. Works by Joyce, Yeats, Synge, Friel, O'Brien, Heaney, Boland, and others. Not offered 2022-23. Instructor: Gilmartin. En/VC 129. Literature/Photography/Facticity. 9 units (3-0-6); third term. "It is the picture of life contrasted with the fact of life, the ideal contrasted with the real, which makes criticism possible," insists Frederick Douglass. This course will take an historical approach to the relationship between literature and photography by examining what Douglass refers to as the contrast between "picture" and "fact" from the advent of photography in the nineteenth century to our present moment. Together, we will think about how each medium creates images, invites different ways of reading or viewing, and makes forms of individual, collective, and political representation possible. We will also examine the ways in which photography and literature shape our understanding of temporality, truth, memory, and history. In addition to our experience of literary and photographic works, theoretical texts on photography will inform the ways of reading and ways of seeing we will develop in this course. Readings may include Boucicault, Douglass, Dunbar, Hartmann, Barthes, Lorde, and Rankine. Not offered 2022-23. Instructor: Hill. En 131. Poe's Afterlife. 9 units (3-0-6); second term. This course focuses on Edgar Allan Poe and the considerable influence his works have had on other writers. Authors as diverse as Charles Baudelaire, Jules Verne, Jorge Luis Borges, Vladimir Nabokov, John Barth, and Philip Roth have used Poe's stories as departure points for their own work. We shall begin by reading some of Poe's s classic short stories, including "The Narrative of Arthur Gordon Pym," "The Purloined Letter," and others. We shall then explore how and why Poe's stories have been so important for authors, despite the fact that his reputation as a great American writer, unlike Hawthorne's and Melville's, for example, is a relatively recent phenomenon. Not offered 2022-23. Instructor: Weinstein. En 132. After Austen: Nineteenth-Century British Women's Writing. 9 units (3-0-6); third term. The Victorian period introduced a huge array of new possibilities and constraints for women of all classes, as it witnessed rapid urbanization and industrialization, a changing conception of marriage and motherhood, and a new set of professional restrictions but also opportunities. This class focuses on novels by and about women, as it seeks to take the measure of these transformations and of a larger culture's reaction to them. How did women imagine and re-imagine themselves and what they wanted? How did notions of femininity and masculinity change? How do the imaginings of the Victorians resonate now? Authors studied may include Eliot, Gaskell, the Brontes, Oliphant, Braddon, and Scheiner. Not offered 2022-23. Instructor: Gilmore. Courses En 133. Paradise Lost. 9 units (3-0-6); first term. We will spend the term studying the famous and eccentric epic poem 'Paradise Lost' (1674) by the British poet and politician John Milton. Each week we will read about 1,000 to 1,500 lines of difficult but beautiful poetry, looking especially for its visual images, literary and mythological references, and poetic sounds, as well as Milton's copious and paradoxical philosophical stances. You will never forget the central character of Satan, the parliament of devils in Hell, the theological conversations in Heaven between God and Jesus, Eve being tempted by diabolical arguments to eat the forbidden fruit, and Adam and Eve being driven from the Garden of Eden at the point of an avenging angel's sword. Instructor: Haugen. En 134. The Career of Herman Melville. 9 units (3-0-6); first term. The course will analyze Melville's career starting with Typee and ending with Billy Budd. Special attention will be given to Moby-Dick and Pierre. The centrality of Melville's position in American literature will be considered from a variety of perspectives, including aesthetics, representations of race, class, and gender, the role of the audience, and connections with other authors. Instructor: Weinstein. En/VC 135. Dickens's London. 9 units (3-0-6); third term. Charles Dickens and London have perhaps the most famous relationship of any writer and city in English. In this course, we will investigate both the London Dickens knew, and the portrait of the city that he painted, by reading one of Dickens's great mid-career novels alongside a selection of contemporary texts and images and secondary historical sources. We will think about the gap-or overlap- between history and fiction, the idea of the novelist as alternative historian, and the idea of the novel as historical document. Historical topics covered may include: the development of the Victorian police force; plague and public health; Victorian poverty; colonialism and imperialism; Dickens and his illustrators; Victorian exhibition and museum culture; and marriage and the cult of domesticity, among others. Students will practice both textual and visual analysis skills. In addition to written work, students should expect to be responsible for making a short research presentation at some point in the term. Not offered 2022-23. Instructor: Gilmore. En 136. The Fiction of Charles Dickens. 9 units (3-0-6); An overview of the Great Inimitable's fiction, concentrating on four texts representative of different phases of his novel-writing career and their relationship to the changing world of Victorian Britain: Oliver Twist, Dombey and Son, Bleak House, Our Mutual Friend. Not offered 2022-23. En 137. African American Literature. 9 units (3-0-6); second term. This course analyzes some of the great works of American literature written by African Americans. This body of writing gives rise to two crucial questions: How does African American literature constitute a literary tradition of its own? How is that tradition inextricable from American literary history? From slave narratives to Toni Morrison's Beloved, from the Harlem Renaissance to Alice Walker, from Ralph Ellison to Walter Mosley, African American literature has examined topics as diverse and English 621 622 important as race relations, class identification, and family life. We shall analyze these texts not only in relation to these cultural issues, but also in terms of their aesthetic and formal contributions. Not offered 2022-23. En 138. Twain and His Contemporaries. 9 units (3-0-6); second term. This course will study the divergent theories of realism that arose in the period after the Civil War and before World War I. Authors covered may include Howells, James, Charlotte Perkins Gilman, Twain, Sarah Orne Jewett, Jacob Riis, Stephen Crane, and W. E. B. DuBois. Instructor: Weinstein. En 139. Ancient Greek Epic Poetry. 9 units (3-0-6); first term. We will start the term by reading Homer's 'lliad' (possibly 8th century B.C.) for two weeks. This is a disconnected, strange, and violent poem, which raises the excellent question how it could become a widely revered classic down to our own time. To look for answers--answers that perhaps also apply to any "classic" book-- we will go on to study the acts of interpretation, revision, and recycling that made the 'lliad' fresh and different, sometimes virtually unrecognizable, for each new generation of readers. We survey surprising ancient Greek philosophical interpretations, a medieval romance by Geoffrey Chaucer set in ancient Troy, a fake Scottish epic poem allegedly composed by "Ossian," Chuck Palahniuk's novel 'Fight Club' (1996), and other works. My suggestion for you will be that the 'lliad' has remained alive for millennia only through quasi-biological processes of mistranscription, mutation, and nonlinear evolution. Not offered 2022-23. Instructor: Haugen. En 150. Chaos and Literature. 9 units (3-0-6); second term. We tend to think of literary texts as models of a stable poetic order, but modern and postmodern writers conduct increasingly bold experiments to test the contrary. This class explores how writers from the nineteenth century onward draw upon ancient and contemporary concepts of chaos to test out increasingly sophisticated models of disorder though writing. Readings to include Lucretius, Serres, Calvino, Barth, Stoppard, and Kehlmann. Not offered 2022-23. Instructor: Holland. En 151. Keeping Time. 9 units (3-0-6); third term. The way in which humans perceive and record time has a discernable history, and literary texts offer us one of the best ways to study it, particularly in times of war and natural catastrophe. With a focus on 16th- through 18th-century European literature, we will examine various techniques of literary time-keeping as they relate to topics such as, fame and mortality, as well as the experience of time's slowness and acceleration. Readings will include selections from Baroque emblem books as well as texts by Montaigne, Milton, Pepys, Defoe, and Rousseau. Not offered 2022-23. Instructor: Holland. En/VC 160 ab. Classical Hollywood Cinema. 9 units (3-0-6); third term. This course introduces students to Hollywood films and filmmaking during the classical period, from the coming of sound through the '50s. Students will develop the techniques and vocabulary appropriate to the Courses distinct formal properties of film. Topics include the rise and collapse of the studio system, technical transformations (sound, color, deep focus), genre (the musical, the melodrama), cultural contexts (the Depression, World War II, the Cold War), audience responses, and the economic history of the film corporations. Terms may be taken independently. Part a covers the period 1927-1940. Part b covers 1941-1960. En/VC 160 b not offered 2022-23. Instructor: Jurca. En/VC 161. The New Hollywood. 9 units (3-0-6); third term. This course examines the post-classical era of Hollywood filmmaking with a focus on the late 1960s through the 1970s, a period of significant formal and thematic experimentation. We will study American culture and politics as well as film in this era, as we consider the relation between broader social transformations and the development of new narrative conventions and cinematic techniques. We will pay particular attention to the changing film industry and its influence on this body of work. Films covered may include Bonnie and Clyde, The Graduate, The Godfather, Taxi Driver, and Jaws. Not offered 2022-23. Instructor: Jurca. En 163. Octavia E. Butler and the Literature of Black Futures. 9 units (3-0-6); third term. We will begin this course by reading a selection of Octavia E. Butler's (1947-2006) novels and short stories, including her 1993 novel Parable of the Sower, which became a New York Times bestseller in 2020. Born here in Pasadena, California in 1947, Butler's writing explored issues such as chattel slavery, climate change, genetic engineering, pandemics, nuclear apocalypse, and post-apocalyptic life. She was also attentive to Black and indigenous modes of care, healing, social justice, and organizing. We will pay special attention to Butler's critical and theoretical contributions to the fields of Afrofuturism, Black studies, feminisms, gender and sexuality studies, and the environmental humanities by reading her works in conjunction with select works of criticism and theory. In the second half of the course, we will explore connections between Butler and the works of other Afrofuturists and Black science fiction writers today, such as Tomi Adeyemi, Akwaeke Emezi, Nalo Hopkinson, N. K. Jemision, Nnedi Okorafor, and others, in order to explore our own ideas for extending Butler's literature of Black futures. Course requirements will likely include class attendance and participation in discussion, weekly reflections on the readings, a midterm project proposal, and a final project and essay. Instructor: Murphy. En 164. Contemporary Black Diasporic Literature and Culture. 9 units (3-0-6); second term. What is a Black diasporic analytic and how might it deepen our understandings of the cultural and literary significance of Black lives around the world? The literary and culturally expressive genius of Black people across the African or Black diaspora has resulted in an extensive tradition within and beyond English-speaking nations. While this course focuses on contemporary Black diasporic literature and culture, it will also foreground the various histories that inform and shape this body of work. Additionally, students will learn how recent works of Black diasporic literature and culture have in turn shaped our current understandings of family, gender, identity, labor, migration, English 623 624 nation, race, sexuality, and more. Overall, this course will serve as an advanced-level introduction to several pivotal Black diasporic literary and cultural works; modes of criticism and methodologies; and the cultural, historical, and social realities of Black people's lives from the 1980s to today. Possible texts include those by Dionne Brand, Edwidge Danticat, Akwaeke Emezi, Bernardine Evaristo, Nalo Hopkinson, Jamaica Kincaid, Paule Marshall, and Caryl Phillips. All readings will be provided in English. Course requirements will likely include class attendance and participation in discussion, weekly reflections on the readings, a midterm project proposal, and a final project and essay. Instructor: Murphy. En 165. Black Feminist and Womanist Literature and Thought. 9 units (3-0-6); second term. For centuries, Black feminists, especially queer and trans women, and non-binary and queer folx, writing in Africa, the Caribbean, Europe, the United States, and more, have used literature to reimagine feminisms. In the decades following the second-wave feminist movement, a body of writing coalesced around the terms "Black feminist" and "womanist." These years are remembered for decolonization and postcolonialism; Anita Hill's testimony; the passing of Title IX; the first Take Back the Night marches; the introduction of terms "intersectionality" by Kimberlé Williams Crenshaw and "third-wave feminism" by Rebecca Walker; the widespread publishing of works by feminists; the creation of Ethnic Studies and Women's and Gender Studies departments across institutions of higher education; and more. It was a moment in which Black people across identities and national origins wrote a number of works that radically retheorized family, home, gender, love, race, sexuality, work, and more, in ways that challenged cultures of violence in favor of imagining beloved communities. In this course, students will read, discuss, and better understand multiple literary and critical works participating in Black feminisms in order to then theorize new possibilities for Black feminist futures. Not offered 2022-23. Instructor: Murphy. VC/En 172. Heritage Studies. 9 units (3-0-6); For course description, see English En 178. Medieval Subjectivities. 9 units (3-0-6); second term. In the seventeenth century, Descartes penned his famous expression "I think therefore I am!" and thus the modern subject was born-or so the simplified story goes. But long before the age of Descartes, the Middle Ages produced an astonishing range of theories and ideas about human selfhood, subjectivity, and interiority. For instance, writing from prison more than one thousand years earlier, Boethius came to realize that what distinguishes a human being from all other creatures is his capacity to "know himself." The meaning of this opaque statement and others like it will command our attention throughout this course, as we explore the diverse, distinctive, and often highly sophisticated notions of subjectivity that developed in the literatures of the Middle Ages. We will take up questions of human agency, free will, identity, self-consciousness, confession, and secrecy as we encounter them in some of the most Courses exciting texts written during the period, including among others Augustine's Confessions, Prudentius's Psychomachia, the Old English poem The Wanderer, the mystical writings of Margery Kempe and Julian of Norwich, and Chaucer's Troilus and Criseyde. Not offered 2022-23. En 179. Constituting Citizenship before the Fourteenth Amendment. 9 units (3-0-6); second term. What can a slave's narrative teach us about citizenship? How did the new nation identify citizens when its Constitution seemed so silent on the matter? And how did one tailor's pamphlet result in one of most massive restrictions of free speech in U.S. history? Our goal over the semester will be to sketch a story of African American literary production from the latter half of the eighteenth century to the Civil War and to tease out, through this literature, developing understandings of citizenship in the United States. We will read letters, poems, sermons, songs, constitutions and bylaws, short stories, and texts that simply defy easy categorization. We will also spend several sessions becoming familiar with key newspapers and magazines-Freedom's Journal, Frederick Douglass's Paper, The Anglo-African Magazine, Christian Recorder, and The Crisis-to deepen our understanding of the kinds of things people were reading and writing on a regular basis and the kinds of arguments they were making. Writers up for discussion may include: Frederick Douglass, James Madison, Harriet Jacobs, Henry David Thoreau, Sojourner Truth, and David Walker. Not offered 2022-23. En 180.

Hardy: The Wessex Novels. 9 units (3-0-6); third term. This course will examine the body of work that the late Victorian novelist Thomas Hardy published under the general title The Wessex Novels, that is, the sequence of works from Far from the Madding Crowd to Jude the Obscure. The six main novels will be read critically to give a sense of the totality of this greatest British regional novelist's achievement. Not offered 2022-23. En 182. Literature and the First Amendment. 9 units (3-0-6); third term. "Freedom of speech," writes Benjamin Cardozo in Palko v. Connecticut (1937), "is the matrix, the indispensable condition, of nearly every other form of freedom." We will go inside the matrix, focusing on how it has affected the books we read. This is not a course in constitutional law or political philosophy, but an opportunity to examine how American literary culture has intersected with law and politics. We will investigate the ways in which the meanings of "freedom," what it entails, and who is entitled to it have changed over time. Possible topics include the obscenity trials surrounding Allen Ginsberg's Howl and James Joyce's Ulysses, crackdowns on anti-war propagandists, and the legal battle between English 625 626 Hustler publisher Larry Flynt and televangelist and Moral Majority cofounder Jerry Falwell. Not offered 2022-23. En 183. Victorian Crime Fiction. 9 units (3-0-6); first term. In 19th-century Britain, for the first time in human history, more of a nation's citizens came to live in urban areas than in rural ones. This result of the Industrial Revolution produced many effects, but in the fiction of the period, one of the most striking was an obsession with the problem of crime. Victorian authors filled their novels with murder, prisons, poisonings, prostitution, criminals, and the new figure of the detective; in this class we will look at the social history, publishing developments, and formal dilemmas that underlay such a response. Authors studied may include Dickens, Collins, Braddon, Conan Doyle, Chesterton, and Conrad, among others. Not offered 2022-23. Instructor: Gilmore. En 185. Dickens and the Dickensian. 9 units (3-0-6); The adjective "Dickensian" makes an almost daily appearance in today's newspapers, magazines, and other media sources. It is used to describe everything from outrageous political scandals, to Bollywood musicals, to multiplot novels. But what does the word really mean? And what part of Charles Dickens's output does it refer to? This class will consider some of Dickens's most famous works alongside a series of contemporary novels, all critically described in "Dickensian" terms. The main concern will be equally with style and form, and 19th-century and present-day circumstances of production (e.g., serialization, mass production, Web publication, etc.). Authors considered (aside from Dickens) may include Richard Price, Zadie Smith, Monica Ali, and Jonathan Franzen. Not offered 2022-23. En 186. The Novel of Education. 9 units (3-0-6); first term. This class takes up a set of mostly very funny, mostly 20th century British novels to frame a simple-seeming, yet deceptively complicated set of questions: What does it mean to be educated? Who has access to education? What does an ideal education consist in? And ultimately: What is a university for? As we think through these questions we will read op/eds and investigative journalism in addition to fiction, and we will consider a variety of university-centered topics (determined by student interest) including issues of gender, class, privilege, race, and genius. Authors read may include Sayers, Larkin, Amis, C.P. Snow, Lodge, and Zadie Smith. Instructor: Gilmore. En 190. Chaucer. 9 units (3-0-6); first term. This course devotes itself to the writings of the diplomat, courtier, bureaucrat, and poet, Geoffrey Chaucer. Best known for the Canterbury Tales, Chaucer also authored dream visions, lyrics, and philosophical meditations. This course will introduce you to some better-known and lesser-known works in the Chaucerian corpus, while also exploring questions central to the production and circulation of literature in the fourteenth and fifteenth centuries. What did it mean to "invent" a literary work in late medieval England? How did Chaucer imagine himself as a writer and reader? What are the hallmarks of Chaucerian style, and how did Chaucer Courses become the canonical author he is today? We will read Chaucer's works in their original language, Middle English, working slowly enough to give participants time to familiarize themselves with syntax and spelling. No previous experience with the language is necessary. Not offered 2022-23. Instructor: Jahner. En 191. Masterworks of Contemporary Latin American Fiction. 9 units (3-0-6); third term.

Cervantes, Truth or Dare: Don Quixote in an Age of Empire. 9 units (3-0-6); second term. Studies Cervantes's literary masterpiece, Don Quixote, with a view to the great upheavals that shaped the early modern world: Renaissance Europe's discovery of America; feudalism's demise and the rise of mass poverty; Reformation and Counter-Reformation; extermination of heretics and war against infidels; and the decline of the Hapsburg dynasty. The hapless protagonist of Don Quixote calls into question the boundaries between sanity and madness, truth and falsehood, history and fiction, objectivity and individual experience. What might be modern, perhaps even revolutionary, in Cervantes's dramatization of the moral and material dilemmas of his time? Conducted in English. Instructor: Wey-Gomez. En/H 197. American Literature and the Technologies of Reading. 9 units (3-0-6); second term. This course explores the material forms of American literature from the colonial era through the nineteenth century.

This course will introduce students to the early development of civilization in Mesopotamia and Egypt from 4000 B.C.E. through 1000 B.C.E. Origins of agriculture and writing, the evolution of the city, and the structures of the Mesopotamian economy and social order will be discussed. Comparison with contemporary developments in Egypt during the Old and Middle Kingdoms may include a reading of Gilgamesh from 3000 B.C.E. and of the Egyptian Tale of Sinuhe. The course concludes with a discussion of life during the late Bronze Age. Focus will be on life as it was lived and experienced by many groups in pre-classical antiquity rather than on kings and dynasties. Instructor: Buchwald. Hum/H 9. Europe Transformed. 9 units (3-0-6); third term. Will introduce students to major aspects of the politics and culture of modernity that have profoundly transformed Western society and consciousness from the French Revolution to the contemporary era. A variety of historical, literary, and artistic works will be used to illuminate major social, intellectual, and cultural movements. The focus will be on significant and wide-ranging historical change (e.g., the industrial revolution, imperialism, socialism, fascism); on cultural innovation (e.g., modernism, impressionism, cubism); and on the work of significant thinkers. Not offered 2022-23. Instructor: Kormos-Buchwald. History 657 658 Hum/H 10. Medieval Europe: The Problem of Violence. 9 units (3-0-6); first, second terms. This course will explore how people understood violence in Europe between ca. 500 and ca. 1400 AD. It will focus on the various norms that governed the use of violence in a period when the right of free people to carry and use weapons was considered self-evident. Working through primary sources, students will explore the relationship between violence and vengeance, the law, central authority and public order, religion, emotions, public ritual, and economics. As they go along students will consider whether violence can coexist with or even promote stable, ordered societies, or whether it by definition creates disorder. Not offered 2022-23. Instructor: Brown. Hum/H 11. Love and Death: Using Demography to Study the History of Europe from 1700. 9 units (3-0-6); first, third terms. Demographic events-births, marriages, deaths-have always been highly responsive to changes in the local environment. Decisions about when to marry, how many children to have, or what kind of household to live in have always been closely correlated to decisions people take in other areas of their lives and, as a result, can tell us a great deal about the economic, social, and cultural worlds people inhabit. This course examines differences in demographic trends in Europe across space and time, from 1700 to the present, as well as existing explanations for these differences, including political economic factors, social and cultural norms, biology and disease environments. Some topics include: the demographic effects of war, industrialization, and urbanization; changes related to the emergence of reliable contraceptive technologies; changes related to the expansion of economic opportunities for women; the effects of government policies on demographic decisions. Not offered 2022-23. Instructor: Dennison. Hum/H 12. Social Theory. 9 units (3-0-6); first term. This course introduces students to both canonical and non-canonical theories of society. From the formative debates over the role of the state in human affairs in early modern Europe to radical interpretations of social good in the twentieth century, students will be exposed to competing theories of society and their implications in the political, the economic, the emotional, and the scientific realms. By the end of the quarter, students will be able to link contemporary notions of individuality, agency, rationality, morality, and ethics to divergent discourses in the history of social theory. Not offered 2022-23. Instructor: Dykstra. Hum/H 13. Brave New Worlds: Race, Human Rights and the Age of Discovery. 9 units (3-0-6); second term. This course traces the origins of modern racism and, perhaps surprisingly, of human rights advocacy itself, to a seminal moment in global history sometimes called the Age of Discovery. At this time, two small European kingdoms, Spain and Portugal, first conducted trade and conquest in Atlantic Africa, the Americas, and the Indian and Pacific Oceans, forging the world's first truly global empires. We study the legacy of racism and humanitarianism in eye-witness accounts, maps, images and other materials attesting to Spain's seminal encounters with the Americas. Instructor: Wey-Gomez. Courses Hum/H/HPS 14. Race, Science, and Medicine in U.S. History. 9 units (3-0-6); second term. This course will explore how natural philosophers and scientists have defined, used, and sometimes challenged ideas about race from the eighteenth century to today. Using a range of primary and secondary sources, we will examine how scientific ideas about race developed in concert with European imperial expansion and slavery; how these ideas were employed in legal cases, medical practice, and eugenics policies; and how activists and scholars have challenged racist practices and ideas. Finally, we will turn to the recent resurgence of racial thinking in biology and medicine in the light of the history of race and science. Instructor: LeBlanc. Hum/H/HPS 15. Waste in the World. 9 units (3-0-6); second, third terms. The things that human beings make and throw away rarely stay where we put them. Just as humans have shaped the biological and physical world, the biological and physical world shapes human actions. In this course, we will examine how these interacting forces propel environmental and cultural change. We will explore these concepts through the lens of waste - how different groups at different points in history define waste, where discarded things go and what they become as they move through space and time. We will consider how conflicting perceptions of utility and waste in different cultural and historical contexts have factored into shifting ideas about race, class, gender, wilderness, technology, consumption, and sovereignty. In rethinking waste, we will explore the multiple meanings of "nature," assess the roots of sustainability, and evaluate past events in light of current ideas about environmental justice. While this course prioritizes reading and discussion, we will also engage with the world around us through visual analysis. Pasadena and Los Angeles will be among our most important resources, allowing us to ground global ideas in a local context. Instructor: Rand. Hum/H/HPS 16. Visualizing the Heavens: Images and Instruments of Early Modern Astronomy. 9 units (3-0-6); first term. In Europe during the period from 1450-1650, there were several radical "revisions" of the universe. Nicolaus Copernicus proposed a sun-centered, rather than earth-centered, cosmos. Galileo Galilei turned his telescope towards the heavens and observed the Moon, Sun, and moons of Jupiter, and the voyages of discovery led to an expansion of the known world. At the same time, the innovation of the printing press played a crucial role in disseminating information and in allowing for astronomical printed images, including celestial atlases and maps, to reach a broad audience. Paintings of the heavens during this period are also a rich source of shifting astronomical ideas. In this course, we'll trace the role that images and instruments of astronomy played in both producing and reflecting these dramatic "revisions" of the universe. We'll study astronomical models, eclipse diagrams, almanacs, and printed instruments, alongside astrolabes, telescopes, and celestial globes, to uncover how images and instruments literally produced a new "vision" of a sun-centered universe for the early modern world. Instructor: Gaida. History 659 660 Hum/H/HPS 17. Materials, Methods, and the Molecularization of Life. 9 units (3-0-6); third term. This course is an introductory exploration of the stuff of modern biology - the practices and objects that biologists have used to produce knowledge of living nature in the nineteenth and twentieth centuries. The course will look at how familiar concepts (e.g. the cell, evolution, the gene) were shaped by scientific workers' adoption of different methods and materials. This approach will allow us to situate biological inquiries within wider political and cultural contexts, while also drawing our attention to the way instruments mediated perceptions in the recording of observations and the execution of experiments. We will trace continuities and changes in the kinds of questions that naturalists and biologists posed, survey spaces in which they pursued their work, and become acquainted with a variety of humans, nonhuman organisms, chemicals, and machines assembled in these spaces. These exercises will familiarize us with diverse forms of labor in and beyond laboratories that have contributed to how humans understood the living world. Instructor: Kollmer. Hum/H/PS 18. Introduction to the History of Science. 9 units (3-0-6); second, third terms. Major topics include the following: What are the origins of modern Western science, when did it emerge as distinct from philosophy and other cultural and intellectual productions, and what are its distinguishing features? When and how did observation, experiment, quantification, and precision enter the practice of science? What were some of the major turning points in the history of science? What is the changing role of science and technology? Using primary and secondary sources, students will take up significant topics in the history of science, from ancient Greek science to the 20th-century revolution in physics, biology, and technology. Hum/H/HPS 10 may be taken for credit toward the additional 36-unit HSS requirement by HPS majors and minors who have already fulfilled their first-year humanities requirement and counts as a history course in satisfying the first-year humanities breadth requirement. Instructor: Feingold. Hum/H 19. Righting the Wrongs of History. 9 units (3-0-6); third term. In recent years, growing numbers of people committed to equity and social justice have discussed various ways of addressing historical injustices whose harms are still experienced in the present. Some have proposed monetary restitution and other restorative strategies that account for resources, opportunities, and lives lost. Others have advocated more symbolic reparative approaches that seek to heal the psychic wounds of injustice. This course will examine efforts to right the wrongs of history, with particular attention given to the decades-long movement for reparations for African Americans and recent efforts to address difficult histories at Caltech. Investigating initiatives that have been realized and others that have been only imagined, in this course we will seek to understand both the possibilities and impossibilities of repairing historical harms. Not offered 2022-23. Instructor: Wiggins. Courses H 60. Reading in History. Units to be determined for the individual by the division; any term.

Looking East/Looking West. 9 units (3-0-6); For course description, see History H 107. The Early Middle Ages. 9 units (3-0-6); second term. This course is designed to introduce students to the formative period of Western medieval history, from roughly 300 to 1000 CE. It will emphasize the development of a new civilization from the fusion of Roman, Germanic, and Christian traditions, with a focus on the Frankish world. The course focuses on the reading, analysis, and discussion of primary sources. Instructor: Brown. H 108. The High Middle Ages. 9 units (3-0-6); third term. This course is designed to introduce students to European history between 1000 and 1400. It will provide a topical as well as chronological examination of the economic, social, political, and religious evolution of western Europe during this period, with a focus on France, Italy, England, and Germany. The course emphasizes the reading, analysis, and discussion of primary sources. Instructor: Brown. H 109. Medieval Knighthood. 9 units (3-0-6); third term. This course tells the story of the knight from his beginnings in the early Middle Ages, through his zenith in the 11th, 12th, and 13th centuries, to his decline and transformation in the late medieval and early modern periods. The course treats the knight not simply as a military phenomenon but also as a social, political, religious, and cultural figure who personified many of the elements that set the Middle Ages apart. Not offered 2022-23. Instructor: Brown. H 111. The Medieval Church. 9 units (3-0-6); second term. This course takes students through the history of the medieval Christian Church in Europe, from its roots in Roman Palestine, through the zenith of its power in the high Middle Ages, to its decline on the eve of the History 661 662 Reformation. The course focuses on the church less as a religion (although it will by necessity deal with some basic theology) than as an institution that came to have an enormous political, social, cultural, and economic impact on medieval life, and for a brief time made Rome once more the mistress of Europe. Not offered 2022-23. Instructor: Brown. H 112. The Vikings. 9 units (3-0-6); second term. This course will take on the Scandinavian seafaring warriors of the 8th-11th centuries as a historical problem. What were the Vikings, where did they come from, and how they did they differ from the Scandinavian and north German pirates and raiders who preceded them? Were they really the horned-helmeted, bloodthirsty barbarians depicted by modern popular media and by many medieval chronicles? What effect did they have in their roughly two centuries of raiding and colonization on the civilizations of medieval and ultimately modern Europe? Not offered 2022-23. Instructor: Brown. H 123. Ordinary People: Uncovering Everyday Life in the European Past. 9 units (3-0-6); second term. In the historical record, much attention is given to wealthy elites (rulers and lawmakers, aristocrats, wealthy merchants), since they were the ones who left written records of their political and economic activities and their personal affairs. But what about the vast majority of people who lived in the past, most of whom were barely literate and had little opportunity to 'make history'? What can we know about them? This class focuses on the lives of ordinary people, and the sources historians use to learn about them. Special attention will be given to women, the poor, and other marginalized groups in societies ranging from England in the west to Russia in the east. Not offered 2022-23. Instructor: Dennison. H 124. Russia. 9 units (3-0-6); first term. Current events have us looking to the past for explanations. How does Russian history help us to understand what is happening in Russia today? Contemporary political commentary emphasizes the recent past: the history of the Soviet Union and its collapse in 1991. This course takes a longer look at Russian political, economic, social, and cultural history - from imperial Russia to the present day. The emphasis is on longer continuities over eras: tsarist, Soviet, post-Soviet. Topics covered include the nature and role of the state, internal politics, rule of law and property rights, serfdom, inequality, art and social commentary, popular resistance, censorship, and the effects of all of these on the lives of ordinary Russians. Instructor: Dennison. H 125. Soviet Russia. 9 units (3-0-6); first term. Why was the Russian Revolution of 1917 successful? And how did the Soviet system survive nearly 75 years? These questions will be addressed in the wider context of Russian history, with a focus on political, economic, and social institutions in the pre- and post-revolutionary period. Subjects covered include the ideological underpinnings of Bolshevism, Lenin and the Bolshevik coup, the rise of Stalin, collectivization, socialist realism, the command economy, World War II, the Krushchev 'thaw', dissident Courses culture and the arts, popular culture, and Gorbachev's perestroika. A variety of sources will be used, including secondary historical literature, fiction, film, and art. Not offered 2022-23. Instructor: Dennison. H/HPS 129. History of Satellites: From Sputnik to Starlink. 9 units (3-0-6); third term. The artificial satellites encircling the planet make up a global information infrastructure. Most of us living in industrialized regions use satellites daily without even realizing it. How did satellites become so integral to terrestrial technological systems? How did Earth orbit transform from a wilderness into a landscape during the second half of the 20th century, and how is that landscape changing in the 21st? We will trace the history of satellites beginning with the first artificial "moons" and moving into the current moment of private industry ascendance, taking into account the development, use, and decay of these technologies. We will consider how designers and users shape satellites, and map out the ways that objects in orbit reflect and reinforce power and geopolitics on the ground below. Not offered 2022-23. Instructor: Rand. H/HPS 130. Technology and Environment in America. 9 units (3-0-6); second term. Political and professional arenas often invoke technology as both a cause and potential solution. In much of mainstream American culture, an enthusiasm for innovation often overshadows the messier ways that humans interact with our surroundings through the artifacts and technologies that we create. In this course, we will examine the interplay between environment and technology in America, from before the arrival of Europeans on the North American continent through present debates about our changing planet. We will consider the boundaries that different groups have drawn between natural and artificial, and how these definitions have shaped the cultural, political, and material landscape of America. How useful are these boundaries? How might rethinking them also help us rethink America's history and its possible future?. Instructor: Rand. H 131. History of Extinction. 9 units (3-0-6); first term. Humans are in the midst of the sixth mass extinction-the first to be caused by human activity. Extinction has been viewed in changing ways over the past 200 years, and this course takes an interdisciplinary approach to learning about the extinction process from a historical as well as a modern perspective. Our focus will be on the extinction of biological entities, but we will also touch on other systems that have disappeared: languages, technologies, habitats, and ways of living. Central to our endeavors will be asking what it means to live in this time of loss: Should we mourn? And if so, how do we mourn for what many or most of us do not see, but only read about? Finally, we will scrutinize what the practical effects of extinction have been, are, and will be. We will also make at least one visit to a natural history museum to view some extinct species behind the scenes. Not offered 2022-23. Instructor: Lewis. H 132. Humanistic Ecology. 9 units (3-0-6); third term. Humans' conceptions of nature have changed dramatically over time. Ecological History 663 664 systems influence human culture, politics, law, and many other spheres, and in turn, humans influence those systems. This class introduces students to the field of humanistic ecology-a discipline that looks to a number of cultural, political, historical and economic elements to better understand the role of ecology in a larger sphere outside of its scientific structure and uses. Humanistic ecology is designed to provide context for the study of ecology, and in a fundamental way, focuses on the appropriate role of humanity in its relationship to nature: what is ethical, or not, what is useful, or not, and a variety of other matters that should be considered when taking a fully three-dimensional view of ecological science. Not offered 2022-23. Instructor: Lewis. H 133. Forests and Humans. 9 units (3-0-6); first term. Forests - which cover 31 percent of the world's land surface - have played essential roles in enhancing the planet's biodiversity. Forests have also served humans in numerous and often controversial ways, and have also been subjected to dramatic change through human activity. How well have we served forests, as well as being served by them? The class will cover the growth and use of forests from a humanistic and historic perspective, as well as discussions about the role of fire in forests, with a particular emphasis on the unprecedented forest fires in California in the past several years and the global ecological implications. Instructor: Lewis. H 134. Birds, Evolution, Speciation and Society. 9 units (3-0-6); second term. The cultural, scientific, social and political roles of birds make them an excellent lens through which to view humans' interactions with the natural world. This course will cover our changing understandings of birds, starting with hawking and falconry in earlier centuries, through the discovery of new species, up through Darwinian understandings of speciation and evolution, and continuing up to present scientific understandings of birds' capabilities and their ties to humankind, as well as to other anchors in the natural world. We will take a strong biographical as well as avian approach to understanding key personalities who furthered our understandings of avian science. Instructor: Lewis. H 136. Caltech in the Archives. 9 units (3-0-6); first term. This class will introduce students to the methods of archival work in the humanities and social sciences. Over the course of the quarter students will receive an introduction to factors surrounding the collection, organization, and use of various types of archives as a background to several small-scale projects working in an archival collection of their own choosing. The seminar will center around weekly projects and synthetic analytical essays about the archival process and archival discoveries. Students hoping to combine their course work with an archive-based research paper may sign up for a separate independent study and conduct research concurrently, with instructor approval. Not offered 2022-23. Instructor: Dykstra. H 137. Criminals, Outlaws, and Justice in a Thousand Years of Chinese History. 9 units (3-0-6); first term. This course explores the Courses shifting boundary between discourses of crime and disobedience over the last millennium or so of Chinese history. It offers fictional, philosophical, political, propagandistic, official, and personal writings on crime and those who commit it as a basis for a wide-ranging series of discussions about when breaking the law is good, when breaking the law is bad, and who gets to decide where the line between a criminal and an outlaw should be drawn. Not offered 2022-23. Instructor: Dykstra. H 138. The Way. 9 units (3-0-6); first term. This course introduces students to some of the seminal writings on the meaning of life, the essentials of rulership, and the place of the individual in the universe from the history of Chinese thought and philosophy. Students are given selected readings from several schools of thought in Chinese history, with an emphasis on the formative Warring States era (the period of the Hundred Schools of classical Chinese philosophy). Instead of being asked to write expository or argumentative essays, participants in this seminar will be introduced to analyzing and presenting texts using the method of annotation. Exposure to the principles of annotation will provide students with a new approach to analyzing and talking about texts both within a humanistic context and beyond. Instructor: Dykstra. H 139. Translation Theory and Practice (Chinese Historical Sources Seminar). 9 units (3-0-6); first term. This seminar will introduce students to the problems and practices of historical translation for academic purposes, with a focus on primary materials from Chinese history. Students will take responsibility for an individual translation project, participate in seminar discussions and collaborative projects to improve the translations being made, and discuss the philosophical and methodological questions at the heart of the practice of translation. Advanced proficiency in written Chinese is required. Students who write analyses (4,000 words) of the sources being translated may enroll in this class as H 139, which satisfies the advanced humanities credit. Not offered 2022-23. Instructor: Dykstra. H/L 142. Perspectives on History through Russian Literature. 9 units (3-0-6); first term. The Russian intelligentsia registered the arrival of modern urban society with a highly articulate sensitivity, perhaps because these changes-industrialization, the breakdown of traditional hierarchies and social bonds, the questioning of traditional beliefs-came to Russia so suddenly. This gives their writings a paradigmatic quality; the modern dilemmas that still haunt us are made so eloquently explicit in them that they have served as models for succeeding generations of writers and social critics. This course explores these writings (in English translation) against the background of Russian society, focusing especially on particular works of Chekhov, Dostoevsky, Goncharov, Tolstoy, and Turgenev. Not offered 2022-23. Instructor: Dennison. H 149. Age of Fracture: America Since 1974. 9 units (3-0-6); third term. In this course, we will examine America after Richard Nixon's resignation in 1974, a period that historians have referred to as an age of fracture and social disaggregation. Using fracture as a conceptual framework to History 665 666 investigate American politics and culture in the last quarter of the twentieth century, we'll consider how the recent past has informed present-day American society. Themes of study will include the culture wars, political polarization, globalization, and the growing wealth gap. In addition, we'll investigate the theoretical and methodological challenges of doing recent history. Not offered 2022-23. Instructor: Wiggins. H 152. Where Do We Go from Here? Black America in the Post-Civil Rights Era. 9 units (3-0-6); first term. This course will examine African American politics, culture, and society in the decades following the passage of landmark civil rights legislation in the 1960s. Topics of discussion will include deindustrialization and the rise of hip hop culture, black feminist and queer thought, debates over welfare and affirmative action, and mass incarceration. Analyzing a variety of political and cultural artifacts as well as cutting-edge secondary literature, we will investigate various moments in recent African American history to gain insight into changing notions of rights, citizenship, equality, and freedom in American society. Not offered 2022-23. Instructor: Wiggins. H/HPS 153. Inequality and Environment. 9 units (3-0-6); first term. This seminar introduces students to the history of environmental inequality, environmental racism, and environmental justice. Human bodies are inescapably enmeshed in our environments: human health and environmental health are inseparable. But environmental burdens and benefits are distributed unevenly along lines of race, gender, class, and nationality. We will examine local, national, and transnational case studies to understand the historical development of environmental inequalities and movements for environmental justice. We will consider different methods for studying environmental injustice and the politics of environmental knowledge. Not offered 2022-23. Instructor: LeBlanc. H/HPS 154. Feminist Science Studies. 9 units (3-0-6); second term. This seminar offers an introduction to scholarship on gender and science. Feminist science studies can seem oxymoronic: the objectivity on which science depends appears opposed to the political commitments feminism implies. Scholars in feminist science studies, however, argue that feminist theory and methods can in fact improve scientific practice. This course will introduce students to the historical development of feminist Science & Technology Studies and what this field tells us about the history of women in science, the history of scientific theories of sex/gender, and the future of feminist research. This reading-heavy class will also include discussions of feminist epistemology, feminist research methods, and new directions in feminist STS. Instructor: LeBlanc. H/HPS 155. Mortality Crises and Social Change: Epidemic Disease from 1300 to the Present. 9 units (3-0-6); third term. What do we know about epidemics in the past? What did contemporaries understand about these events? How did societies respond to periodic bouts of epidemic disease? This course examines mortality crises and epidemics from the Black Death in the 14th century to the current coronavirus Courses pandemic, with attention given to the impact of epidemics on societies, the ways in which such outbreaks have been understood over time and the kinds of responses they have elicited. We will draw on studies for a range of societies in order to identify patterns across space and time, and to highlight both continuity and change in the ways societies have dealt with contagious diseases. Not offered 2022-23. Instructor: Dennison. H/HPS 156. COVID-19 and Other Pandemics. 9 units (3-0-6); second term. How do we understand the COVID pandemic and the differential responses to it around the globe? What is the best framework for proper understanding? Science, history, politics, culture? Special attention will be given to the state of medical science today and in the past, the understanding of ethology, transmission, and symptoms; the role of scientists, physicians, and "quacks"; the persistence and change in the forms of fear, superstition, and misinformation across time. Not offered 2022-23. Instructor: Kormos-Buchwald. HPS/H 157. Models and Theory in Ancient Astronomy: From the Babylonians to the Greeks. 9 units (3-0-6); third term. In the context of knowledge of heavenly phenomena, model-making played a continuous role throughout the history of Babylonian astronomy, from the 2nd millennium BCE to the Hellenistic period. This course looks selectively at the development of models for astronomy, from arithmetical linear models in 2nd millennium BCE to 1st century BCE Babylonia to the geometrical cinematic models of Hellenistic Greek astronomy. Questions about the relationship of observation to theory and model-making, and the relationship of astronomical models to the representation of the motion of heavenly bodies and to cosmology will be of interest. The material will be set against its historical and cultural contexts, including the relationship of astronomy to astrology. Readings will be taken from cuneiform texts and translations of Greek astronomical treatises. Instructor: Rochberg. HPS/H 160. Einstein and His Generation: The History of Modern Physical Sciences. 9 units (3-0-6); third term. An exploration of the most significant scientific developments in the physical sciences, structured around the life and work of Albert Einstein (1879-1955), with particular emphasis on the new theories of radiation, the structure of matter, relativity, and quantum mechanics. While using original Einstein manuscripts, notebooks, scientific papers, and personal correspondence, we shall also study how experimental and theoretical work in the sciences was carried out; scientific education and career patterns; personal, political, cultural, and sociological dimensions of science. Not offered 2022-23. Instructor: Kormos-Buchwald. H 161. Selected Topics in History. 9 units (3-0-6); offered by announcement. This is an advanced humanities course on a specialized topic in History.

History 667 668 Instructors: Staff, visitors. HPS/H 162. Social Studies of Science. 9 units (3-0-6); second term. A comparative, multidisciplinary course that examines the practice of science in a variety of locales, using methods from the history, sociology, and anthropology of scientific knowledge. Topics covered include the high-energy particle laboratory as compared with a biological one; Western as compared to non-Western scientific reasoning; the use of visualization techniques in science from their inception to virtual reality; gender in science; and other topics. Instructor: Feingold. VC/H/HPS 164. Fashion and Waste. 9 units (3-0-6); For course description, see History HPS/H 166. Historical Perspectives on the Relations between Science and Religion. 9 units (3-0-6); third term. The course develops a framework for understanding the changing relations between science and religion in Western culture since antiquity. Focus will be on the ways in which the conceptual, personal, and social boundaries between the two domains have been reshaped over the centuries. Questions to be addressed include the extent to which a particular religious doctrine was more or less amenable to scientific work in a given period, how scientific activity carved an autonomous domain, and the roles played by scientific activity in the overall process of secularization. Instructor: Feingold. HPS/H 167. Experimenting with History/Historic Experiment. 9 units (3-0-6); third term. Prerequisites: Ph 1 abc, and Ph 2 abc (may be taken concurrently). This course uses a combination of lectures with hands-on laboratory work to bring out the methods, techniques, and knowledge that were involved in building and conducting historical experiments. We will connect our laboratory work with the debates and claims made by the original discoverers, asking such questions as how experimental facts have been connected to theories, how anomalies arise and are handled, and what sorts of conditions make historically for good data. Typical experiments might include investigations of refraction, laws of electric force, interference of polarized light, electromagnetic induction, or resonating circuits and electric waves. We will reconstruct instrumentation and experimental apparatus based on a close reading of original sources. Not offered 2022-23. Instructor: Buchwald. HPS/H 168.

Not offered 2022-23. Instructor: Buchwald. HPS/H 171. History of Mechanics from Galileo through Euler. 9 units (3-0-6); Prerequisites: Ph 1 abc, and Ph 2 abc (may be taken concurrently). This course covers developments in mechanics, as well as related aspects of mathematics and models of nature, from just before the time of Galileo through the middle of the 18th century, which saw the creation of fluid and rotational dynamics in the hands of Euler and others. Not offered 2022-23. HPS/H 172. History of Mathematics: A Global View with Close-ups. 9 units (3-0-6); offered by announcement. The course will provide students with a brief yet adequate survey of the history of mathematics, characterizing the main developments and placing these in their chronological, cultural, and scientific contexts. A more detailed study of a few themes, such as Archimedes' approach to infinite processes, the changing meanings of "analysis" in mathematics, Descartes' analytic geometry, and the axiomatization of geometry c. 1900; students' input in the choice of these themes will be welcomed. Not offered 2022-23. HPS/H 173. Classification and its Consequences in Modern Biology and Medicine. 9 units (3-0-6); first term. In Plato's Phaedrus, Socrates famously described the virtues of two ways of looking at the world. The first entailed "seeing together things that are scattered about everywhere and collecting them into one kind," while the second was the skill "to cut up each kind according to its species along its natural joints, and to try not to splinter any part, as a bad butcher might do." In a similar sentiment, Darwin wrote in 1857, "It is good to have hair-splitters and lumpers." How have scientists and laypeople perceived similarities and differences in the living world? How have they divided nature into distinct kinds and individuals? How have they distinguished between parts and wholes? Where have they positioned human beings within nature's order? What were the consequences of finding different kinds of order in nature? This course explores these and related questions historically. We will consider different approaches to making sense of nature, and how a multitude of perspectives have been brought to bear on this ordering project. Topics covered include taxonomy and classification, race science and scientific racism, gender and sex differences, disease categories and immune selfhood, and symbioses and biogeochemical cycles. Instructor: Kollmer. HPS/H 174. History of Biotechnology. 9 units (3-0-6); second term. Humans excel at using other organisms, including other humans, as means to ends. From the beginnings of agriculture, our species has cultivated crops, livestock, and microbial fermenters as living History 669 670 technologies of production. In modern industrial economies, human uses of life have undergone radical changes, as have the values humans assigned different forms of life. Agriculture underwent rationalization and intensification, increasing yields many times over. Scaled-up fermentation techniques served to preserve food, manufacture drugs, and process wastes. In vitro fertilization and somatic cell nuclear transfer permitted dramatic interventions in sexual reproduction. This course will explore these and other histories of biotechnology across different temporal, geographic, and cultural contexts, paying special attention to the ambivalent relationships that arose between user and used in such HPS/H 175. Matter, Motion, and Force: Physical Astronomy from Ptolemy to Newton. 9 units (3-0-6); second term. The course will examine how elements of knowledge that evolved against significantly different cultural and religious backgrounds motivated the great scientific revolution of the 17th century. Not offered 2022-23. HPS/H 176. The Occult Origins of Modern Science: Alchemy, Astrology, and Magic. 9 units (3-0-6); first, second terms. Modern science is often described as a rational, empirical, and objective search for truth about nature. But how, when, and why did science come to acquire these qualities? Many scholars look to the exciting developments and discoveries of the sixteenth and seventeenth centuries in Europe-the so-called "Scientific Revolution"-as the defining period for the emergence of modern science. If "modern" science is defined in these terms, then "premodern" science must have looked more like pseudo-science, superstition, or myth. However, that is far from the truth. In this course, we'll work to uncover the role that the occult sciences, including alchemy, astrology, and magic, played in the formation of modern science. Our studies of the occult sciences will force us to think more deeply about what distinguishes modern science from the occult sciences, and to question why their role in the development of modern science has also been obscured. Instructor: Gaida. HPS/H 180. Forbidden Knowledge. 9 units (3-0-6); first term. Why does the notion of freedom of knowledge and teaching in science and engineering matter? What kinds of restrictions have been placed on scientists and engineers, their publications and institutions? Who restrained scientific and engineering knowledge of what sorts; for what reasons; and how successfully? These questions will be addressed by exploring the strategies developed by the U.S. research community to protect the international circulation of knowledge after World War II, when scientific freedom and the export of technical data had to be balanced with the needs of national security. Case studies will include the atomic bomb, the semiconductor industry in the 1970s and space technologies, notably rockets/missiles, in the 1990s. The threat to U.S. economics and military security posed by the Soviet Union in the Cold War, and by China today, has transformed the practice of research in university and in industry alike building new walls around the production Courses and circulation of knowledge to affirm national sovereignty that is, all the while, being undermined by the global circulation of trained scientists and engineers. Not offered 2022-23. Instructor: Faculty. H/HPS/VC 185. Angels and Monsters: Cosmology, Anthropology, and the Ends of the World. 9 units (3-0-6); second term. This course explores late medieval European understandings of the origins, structure, and workings of the cosmos in the realms of theology, physics, astronomy, astrology, magic, and medicine. Attention is given to the position of humans as cultural creatures at the intersection of nature and spirit; as well as to the place of Christian Europeans in relation to non-Christians and other categories of outsiders within and beyond Europe. We will examine the knowledge system that anticipated racializing theories in the West. Not offered 2022-23. Instructor: Wey-Gomez. H/HPS/VC 186. From Plato to Pluto: Maps, Exploration and Culture from Antiquity to the Present. 9 units (3-0-6); second term. This course covers a broad range of topics in the history of maps and exploration from Antiquity to the present. These topics range from the earliest visualizations of earth and space in the Classical world to contemporary techniques in interplanetary navigation. By way of maps, students will explore various ways in which different cultures have conceptualized and navigated earth and space. While maps emulate the world as perceived by the human eye, they, in fact, comprise a set of observations and perceptions of the relationship between bodies in space and time. Thus, students will study maps, and the exploration they enable, as windows to the cultures that have produced them, not only as scientific and technical artifacts to measure and navigate our world. Not offered 2022-23. Instructors: Ceva, Wey-Gomez. H/L 191. Perspectives on History through German Literature. 9 units (3-0-6); third term. Industrialization, economic growth, and democracy came to Germany much later than to England and France, and the forms they took in Germany were filtered through the specific institutional character of Central Europe. German-speaking writers and intellectuals saw these trends from the perspective of indigenous intellectual traditions, and the resulting collisions of values and priorities largely shaped European and American social, political, and literary debates for much of the nineteenth and twentieth centuries. This course explores these writings (in English translation) against the historical background of Central European society, focusing on particular works of Goethe, Hoffmann, Heine, Nietzsche, Kafka, Rilke, and Mann. Not offered 2022-23. Instructor: Dennison. H 192. The Crusades. 9 units (3-0-6); third term. This course will introduce students to the series of religiously motivated European invasions of the Middle and Near East that began at the end of the eleventh century and that led to the creation of Latin Christian principalities in Palestine. Though the crusading movement came to embroil much of Europe itself, the course will focus strictly on the military History 671 672 expeditions to what the Crusaders called the Holy Land, and the history of the Crusader states up to the point of their destruction at the end of the thirteenth century. The course will be guided by the following questions: how did medieval Christianity justify wars of aggression against foreign peoples and religions? What motivated western Europeans to leave their homes and march into a hostile environment, where they often faced impoverishment if not death and where maintaining a Christian presence was a constant struggle? How did they manage to erect stable political entities in alien territory that lasted as long as they did, and how did they have to adapt their own culture to do so? Finally, how did the native peoples of the regions the Crusaders invaded and conquered-Muslim but also Christian and Jewish - perceive the Crusaders? How did the Crusaders' presence affect life in a region whose populations had their own ancient histories and patterns of life? Not offered 2022-23. Instructor: Brown. En/H 193.

This course will critically examine attempts to understand moral judgment and behavior from the perspective of neuroscience and controversies surrounding its implications for moral philosophy. Starting from an evolutionary perspective, we will investigate the search for moral precursors in non-human primates and the evolutionary innovations in cognitive, emotional, and motivational mechanisms purported to underlie human morality. From there, we will investigate controversies regarding Courses this emerging "neuroethics" for debates in moral psychology and normative ethics, including the role of reason, desire, and the self in normative theory and whether neuroscience can play any role in adjudicating among competing theories of normative ethics. Instructor: Quartz. HPS/PI 136. Happiness and the Good Life. 9 units (3-0-6); first term.

Instructor: Quartz. HPS/PI 138. Human Nature and Society. 9 units (3-0-6); first term. This course will investigate how assumptions about human nature shape political philosophy, social institutions, and social policy. The course will begin with a historical perspective, examining the work of such political philosophers as Plato, Locke, Rousseau, and Marx, along with such psychologists as Freud and Skinner. Against this historical perspective, it will then turn to examine contemporary views on human nature from cognitive neuroscience and evolutionary psychology and explore their potential implications for political philosophy and social policy. Among topics to be discussed will be the nature of human sociality and cooperation; economic systems and assumptions regarding production and consumption; and propaganda, marketing, and manipulation. Not offered 2022-23. Instructor: Quartz. HPS/PI 139. Human Nature, Welfare, & Sustainability. 9 units (3-0-6); first term. Policy makers since at least the time of Jeremy Bentham have argued that welfare maximization ought to be the goal of social policy. When this includes perfectionist notions of realizing one's capacities, economic prosperity, prosocial norms, and democratization have all coincided as key drivers of human development. Although the UN 2030 Agenda for Sustainable Development envisions worldwide inclusive and sustainable economic growth, there is substantial debate regarding the extent to which sustainability and economic growth are compatible. This course will critically examine the links between human welfare, economic growth, and material culture to better understand why economic growth and welfare have been taken to be intertwined - and the extent to which they could be decoupled. Our starting point will be the Brundtland report, its conception of welfare based on human needs, and subsequent articulations of needs-based theories of human welfare, including evolutionary and biological accounts that include social comparison processes such as esteem, status, and recognition. This will provide us with a theoretical framework for investigating the role of History and Philosophy of Science 675 676 material culture in satisfying these needs and whether they may be satisfied by less resource-intense routes.

In the context of knowledge of heavenly phenomena, model-making played a continuous role throughout the history of Babylonian astronomy, from the 2nd millennium BCE to the Hellenistic period. This course looks selectively at the development of models for astronomy, from arithmetical linear models in 2nd millennium BCE to 1st century BCE Babylonia to the geometrical cinematic models of Hellenistic Greek astronomy. Questions about the relationship of observation to theory and model-making, and the relationship of astronomical models to the representation of the motion of heavenly bodies and to cosmology will be of interest. The material will be set against its historical and cultural contexts, including the relationship of astronomy to astrology. Readings will be taken from cuneiform texts and translations of Greek astronomical treatises. Instructor: Rochberg. HPS/H 160. Einstein and His Generation: The History of Modern Physical Sciences. 9 units (3-0-6); third term.

The civilizations of Egypt and Mesopotamia gave rise to complex forms of religious practices connected to the social order, moral behavior, and the afterlife. The course examines the origins of concepts of moral death and of sin as a violation of cosmic order in antiquity, the nature of polytheism, and the manner in which monotheism arose out of it. In addition to historical analyses the course includes readings by anthropologists who have studied cult structures as well as contemporary theories by evolutionary psychologists. Not offered 2022-23. Instructor: Buchwald. Hum/H 8. Civilization, Science, and Archaeology: Before Greece: The Origins of Civilization in Mesopotamia. 9 units (3-0-6); second, third terms. This course will introduce students to the early development of civilization in Mesopotamia and Egypt from 4000 B.C.E. through 1000 B.C.E. Origins of agriculture and writing, the evolution of the city, and the structures of the Mesopotamian economy and social order will be discussed. Comparison with contemporary developments in Egypt during the Old and Middle Kingdoms may include a reading of Gilgamesh from 3000 B.C.E. and of the Egyptian Tale of Sinuhe. The course concludes with a discussion of life during the late Bronze Age. Focus will be on life as it was lived and experienced by many groups in pre-classical antiquity rather than on kings and dynasties. Instructor: Buchwald. Hum/H 9. Europe Transformed. 9 units (3-0-6); third term. Will introduce students to major aspects of the politics and culture of modernity that have profoundly transformed Western society and consciousness from the French Revolution to the contemporary era. A variety of historical, literary, and artistic works will be used to illuminate major social, intellectual, and cultural movements. The focus will be on significant and wide-ranging historical change (e.g., the industrial revolution, imperialism, socialism, fascism); on cultural innovation (e.g., modernism, impressionism, cubism); and on the work of significant thinkers. Not Humanities 681 682 offered 2022-23. Instructor: Kormos-Buchwald. Hum/H 10. Medieval Europe: The Problem of Violence. 9 units (3-0-6); first, second terms. This course will explore how people understood violence in Europe between ca. 500 and ca. 1400 AD. It will focus on the various norms that governed the use of violence in a period when the right of free people to carry and use weapons was considered self-evident. Working through primary sources, students will explore the relationship between violence and vengeance, the law, central authority and public order, religion, emotions, public ritual, and economics. As they go along students will consider whether violence can coexist with or even promote stable, ordered societies, or whether it by definition creates disorder. Not offered 2022-23. Instructor: Brown. Hum/H 11. Love and Death: Using Demography to Study the History of Europe from 1700. 9 units (3-0-6); first, third terms. Demographic events-births, marriages, deaths-have always been highly responsive to changes in the local environment. Decisions about when to marry, how many children to have, or what kind of household to live in have always been closely correlated to decisions people take in other areas of their lives and, as a result, can tell us a great deal about the economic, social, and cultural worlds people inhabit. This course examines differences in demographic trends in Europe across space and time, from 1700 to the present, as well as existing explanations for these differences, including political economic factors, social and cultural norms, biology and disease environments. Some topics include: the demographic effects of war, industrialization, and urbanization; changes related to the emergence of reliable contraceptive technologies; changes related to the expansion of economic opportunities for women; the effects of government policies on demographic decisions. Not offered 2022-23. Instructor: Dennison. Hum/H 12. Social Theory. 9 units (3-0-6); first term. This course introduces students to both canonical and non-canonical theories of society. From the formative debates over the role of the state in human affairs in early modern Europe to radical interpretations of social good in the twentieth century, students will be exposed to competing theories of society and their implications in the political, the economic, the emotional, and the scientific realms. By the end of the quarter, students will be able to link contemporary notions of individuality, agency, rationality, morality, and ethics to divergent discourses in the history of social theory. Not offered 2022-23. Instructor: Dykstra. Hum/H 13. Brave New Worlds: Race, Human Rights and the Age of Discovery. 9 units (3-0-6); second term. This course traces the origins of modern racism and, perhaps surprisingly, of human rights advocacy itself, to a seminal moment in global history sometimes called the Age of Discovery. At this time, two small European kingdoms, Spain and Portugal, first conducted trade and conquest in Atlantic Africa, the Americas, and the Indian and Pacific Oceans, forging the world's first truly global empires. We study the legacy of racism and humanitarianism Courses in eye-witness accounts, maps, images and other materials attesting to Spain's seminal encounters with the Americas. Instructor: Wey-Gomez. Hum/H/HPS 14. Race, Science, and Medicine in U.S. History. 9 units (3-0-6); second term. This course will explore how natural philosophers and scientists have defined, used, and sometimes challenged ideas about race from the eighteenth century to today. Using a range of primary and secondary sources, we will examine how scientific ideas about race developed in concert with European imperial expansion and slavery; how these ideas were employed in legal cases, medical practice, and eugenics policies; and how activists and scholars have challenged racist practices and ideas. Finally, we will turn to the recent resurgence of racial thinking in biology and medicine in the light of the history of race and science. Instructor: LeBlanc. Hum/H/HPS 15. Waste in the World. 9 units (3-0-6); second, third terms. The things that human beings make and throw away rarely stay where we put them. Just as humans have shaped the biological and physical world, the biological and physical world shapes human actions. In this course, we will examine how these interacting forces propel environmental and cultural change. We will explore these concepts through the lens of waste - how different groups at different points in history define waste, where discarded things go and what they become as they move through space and time. We will consider how conflicting perceptions of utility and waste in different cultural and historical contexts have factored into shifting ideas about race, class, gender, wilderness, technology, consumption, and sovereignty. In rethinking waste, we will explore the multiple meanings of "nature," assess the roots of sustainability, and evaluate past events in light of current ideas about environmental justice. While this course prioritizes reading and discussion, we will also engage with the world around us through visual analysis. Pasadena and Los Angeles will be among our most important resources, allowing us to ground global ideas in a local context. Instructor: Rand Hum/H/HPS 16. Visualizing the Heavens: Images and Instruments of Early Modern Astronomy. 9 units (3-0-6); first term. In Europe during the period from 1450-1650, there were several radical "revisions" of the universe. Nicolaus Copernicus proposed a sun-centered, rather than earth-centered, cosmos. Galileo Galilei turned his telescope towards the heavens and observed the Moon, Sun, and moons of Jupiter, and the voyages of discovery led to an expansion of the known world. At the same time, the innovation of the printing press played a crucial role in disseminating information and in allowing for astronomical printed images, including celestial atlases and maps, to reach a broad audience. Paintings of the heavens during this period are also a rich source of shifting astronomical ideas. In this course, we'll trace the role that images and instruments of astronomy played in both producing and reflecting these dramatic "revisions" of the universe. We'll study astronomical models, eclipse diagrams, almanacs, and printed instruments, alongside astrolabes, telescopes, and celestial globes, to Humanities 683 684 uncover how images and instruments literally produced a new "vision" of a sun-centered universe for the early modern world. Instructor: Gaida. Hum/H/HPS 17. Materials, Methods, and the Molecularization of Life. 9 units (3-0-6); third term. This course is an introductory exploration of the stuff of modern biology - the practices and objects that biologists have used to produce knowledge of living nature in the nineteenth and twentieth centuries. The course will look at how familiar concepts (e.g. the cell, evolution, the gene) were shaped by scientific workers' adoption of different methods and materials. This approach will allow us to situate biological inquiries within wider political and cultural contexts, while also drawing our attention to the way instruments mediated perceptions in the recording of observations and the execution of experiments. We will trace continuities and changes in the kinds of questions that naturalists and biologists posed, survey spaces in which they pursued their work, and become acquainted with a variety of humans, nonhuman organisms, chemicals, and machines assembled in these spaces. These exercises will familiarize us with diverse forms of labor in and beyond laboratories that have contributed to how humans understood the living world. Instructor: Kollmer. Hum/H/HPS 18. Introduction to the History of Science. 9 units (3-0-6); second, third terms. Major topics include the following: What are the origins of modern Western science, when did it emerge as distinct from philosophy and other cultural and intellectual productions, and what are its distinguishing features? When and how did observation, experiment, quantification, and precision enter the practice of science? What were some of the major turning points in the history of science? What is the changing role of science and technology? Using primary and secondary sources, students will take up significant topics in the history of science, from ancient Greek science to the 20th-century revolution in physics, biology, and technology. Hum/H/HPS 10 may be taken for credit toward the additional 36-unit HSS requirement by HPS majors and minors who have already fulfilled their first-year humanities requirement and counts as a history course in satisfying the first-year humanities breadth requirement. Instructor: Feingold. Hum/H 19. Righting the Wrongs of History. 9 units (3-0-6); third term. In recent years, growing numbers of people committed to equity and social justice have discussed various ways of addressing historical injustices whose harms are still experienced in the present. Some have proposed monetary restitution and other restorative strategies that account for resources, opportunities, and lives lost. Others have advocated more symbolic reparative approaches that seek to heal the psychic wounds of injustice. This course will examine efforts to right the wrongs of history, with particular attention given to the decades-long movement for reparations for African Americans and recent efforts to address difficult histories at Caltech. Investigating initiatives that have been realized and others that have been only imagined, in this course we will seek to understand both the possibilities and impossibilities of repairing historical harms. Not offered 2022-23. Instructor: Wiggins. Courses Hum/En 21. Monsters and Marvels. 9 units (3-0-6); second, third terms. Marvels flourish at the boundaries of literary invention, religious belief, and scientific inquiry, challenging assumptions about natural processes and expected outcomes. From Grendel, the monstrous foe of Beowulf, to Satan, Milton's charismatic antihero, this seminar examines the uses of the marvelous in a variety of texts and genres, including Shakespearian drama, medieval romance, and early travel-writing. Readings may include Beowulf, Marie de France, Chaucer, John Mandeville, Shakespeare, Milton. Instructor: Jahner. Hum/En 22. Inequality. 9 units (3-0-6); third term. Throughout the history of Europe, America, and beyond, poets and philosophers have asked hard questions about unequal relationships, whether between kings and subjects, gods and humans, men and women, rich and poor, or machines and people. Our authors take no single point of view; our goal is to analyze sophisticated and often surprising arguments and to enter new cultural worlds. Readings may include Ovid, Milton, Sei Shonagon, Machiavelli, Rousseau, and Alexievich. Instructor: Haugen. Hum/En 23. Literature and Medicine. 9 units (3-0-6); third term. The relationship between patients and doctors, the ill and the well, involves a constant exchange of stories. In this course we will look more closely at the relationship between medicine and narrative through a selection of fiction, essays and poems that investigate the interplay between doubt and diagnosis, the idea of the case study, the problem of medical responsibility, and the language of pain and illness. Authors covered may include Sontag, Mantel, Conan Doyle, Freud, Woolf, Dickinson, Ishiguro and Shelley. Not offered 2022-23. Instructor: Gilmore. Hum/En 24. The Scientific Imagination in English Literature. 9 units (3-0-6); first term. This course considers three periods of major scientific development-the Renaissance, the nineteenth century, and the modern period- to explore the influence new ideas, discoveries, and theories had on the imagination of English writers. We will look at the early modern interplay between magic and science, Romantic and Victorian debates about evolution, and the twentieth-century advent of modern physics as we confront consistent tropes like the mad scientist, the scientist-hero, and the problem of uncertainty. Authors covered may include Shakespeare, Marlowe, Bacon, Shelley, Darwin, Conan Doyle, Stevenson, Auden, McEwan, and Stoppard. Not offered 2022-23. Instructor: Gilmore. Hum/En 25. The Human Animal. 9 units (3-0-6); third term. European literature has long been a testing ground for radical new ideas which have come to shape our basic understanding of what it means to be a thinking, speaking and perhaps even autonomous human being. The question of what - if anything - makes us different from animals was debated from numerous points of view: including talking dogs, philosophizing women, bestial men, humanlike beasts, and other creatures that defied the conventions of the time. This course explores Humanities 685 686 some of the key literary texts that shaped this debate and pays careful attention to their cultural environments. Selected readings from Cervantes, La Fontaine, Swift, Rousseau, Buffon, Aikin, and Wollstonecraft, among others. Instructor: Holland. Hum/En 26. What Is Imagination?. 9 units (3-0-6); third term. Albert Einstein once said that imagination is everything, and even more important than knowledge. This course invites you to think about - and use - your imagination as we explore how the act of imagining has been viewed over time in the service of memory and creativity, in both the arts and the sciences. Readings will focus on the eighteenth and nineteenth centuries and will include Hume, Moritz, Kant, Novalis, Hoffmann, Coleridge, and Wordsworth. Not offered 2022-23. Instructor: Holland. Hum/En 29. Dream Narratives. 9 units (3-0-6); third term. Dream narratives reveal as much about cultural beliefs and superstitions as they do about techniques of narration and interpretation. This course investigates key developments in the literature on dreams and dream interpretations with examples drawn from the Renaissance through the beginning of the nineteenth century. Selected readings from Boccaccio, Descartes, Calderón, Shakespeare, and Diderot, among others. Not offered 2022-23. Instructor: Holland. Hum/En 30. Reading Animals. 9 units (3-0-6); first term. In this course we will look closely at representations of nonhuman animals in literature from the Middle Ages to our present moment as opportunities to revisit definitions of, and the boundaries created and blurred between, the "human" and the "animal." Readings may include Marie de France, Marianne Moore, Franz Kafka, Donna Haraway, Donika Kelly, and K-Ming Chang. Instructor: Hill. Hum/En 31. Introduction to Black Literature and Culture in the United States. 9 units (3-0-6); second term. As both a celebration and remembrance of Black expressive thought, this course will serve as an introduction to Black literature and culture across several US geographic regions from the standpoint of a variety of intersectional identities and experiences. This course centers on how the artistic, cultural, and literary lives of Black people have shaped US economic, political, and social history since before the nation's founding. In addition to literary texts, this course will introduce students to several examples of cultural expression that have also become beloved touchstones in Black cultural history. Because literary works and works of cultural expression by Black people have long informed the possibilities of American artistic expression and critical thought, they provide possible blueprints for how US life might unfold in the future. Students will learn to apply several existing contexts and methodologies for the study of Black literature and culture, propose directions for future study, and explore their own unique possibilities for deepening their relationships to this body of work. Possible authors include Zora Neale Hurston, Lorraine Hansberry, James Baldwin, Ernest J. Gaines, Toni Morrison, Octavia E. Butler, and Akwaeke Emezi. Course requirements will likely include class attendance Courses and participation in discussion, weekly reflections on the readings, a take-home midterm examination, and a take-home final essay. Instructor: Murphy. Hum/En 32. Introduction to Black Feminist Poetics. 9 units (3-0-6); third term. This course is a comprehensive exploration of the poetics (acts of making) of Black feminisms across literature, culture, and theory, centering on works that engage social justice, healing practices, abolition, self-care, and more. Students will read and study several examples of the lives and works of Black LBGTQ+ people and others who have long reimagined dis/ability, ethics, gender, race, and sexuality within Black feminist contexts. Such works have radically retheorized community, embodiment, home, self-love, and more, in ways that challenge cultures of violence in favor of imagining beloved communities and futures. Through a combination of regular study and practice, students will build expertise to practice black feminist poetics in their own lives and work and will propose their own goals for future study in the field. Instructor: Murphy. Hum/En 33. Modern Metamorphoses. 9 units (3-0-6); second term. Narratives of metamorphosis have traditionally used their dramatic subject matter-a radical change of form-as a vehicle for social criticism. This course explores the ways in which twentieth-century writers experiment with the concept of metamorphosis to take on the most pressing political and social issues of their day, including slavery, women's rights, and critiques of capitalist excess. Readings to include Kafka, Garnett, Orwell, Tawada, and Erpenbeck. Not offered 2022-23. Instructor: Holland. Hum/En 34. Literature and Deception. 9 units (3-0-6); second term. In this course, we will be considering lying and other types of deception from the point of view of literature and philosophy, with two main goals in mind: 1) to compare cultural practices of deception at various times in European history and 2) to think in general terms about the ability of a literary text to convey truth and falsehood. Can a fictional text be "true" in any meaningful sense, such as a political one? Or, as many people have thought over time, is it more accurate to think about literature as a beautiful lie? Readings will include the legend of Till Eulenspiegel as well as texts by Machiavelli, Shakespeare, Diderot, and those relating to the Ossian controversy. Not offered 2022-23. Instructor: Holland. Hum/En 35. Beginning with Poems. 9 units (3-0-6); first, second terms. Why begin the study of literature with poems? Written words are the building blocks of literature, and poetry, in Coleridge's famous equation, is "the best words in the best order." To be understood and appreciated, poetry requires a close attention to words and their ordering as they are read and reread. All good literature requires such attention, but practically speaking, poetry provides the best way to acquire the art of rereading because of its shorter forms. More importantly, poetry can be the most emotionally intense and satisfying of literary forms. We will read a small number of poems written in English from the sixteenth to the Humanities 687 688 twentieth centuries from several genres - sonnet, ode, elegy, verse epistle, satire, villanelle - and on several subjects - love, death, and politics. Poets will include William Shakespeare, Emily Dickinson, and William Butler Yeats. Instructor: Pigman. Hum/En 36. American Literature and Culture. 9 units (3-0-6); second term. Studies of American aesthetics, genres, and ideas from the birth of the nation to the present. Students will be introduced to the techniques of formal analysis. We will consider what constitutes evidence in relation to texts and how to develop a persuasive interpretation. Topics may include Nature's Nation, slavery and its aftermath, individualism and the marketplace, the "New Woman," and the relation between word and image. Instructor: Weinstein. Hum/P| 40. Right and Wrong. 9 units (3-0-6); first, second terms. This course addresses questions such as: Where do our moral ideas come from? What justifies them? How should they guide our conduct, as individuals and as a society? What kind of person should one aspire to be? Topics the course may deal with include meta-ethical issues (e.g., What makes an action right or wrong? When is one morally responsible for one's actions? How should society be organized?) and normative questions (e.g., Is eating meat morally acceptable? What should we tolerate and why? What are society's obligations toward the poor?). In addition, the psychological and neural substrates of moral judgment and decision making may be explored. The course draws on a variety of sources, including selections from the great works of moral and political philosophy (e.g., Aristotle's Nichomachean Ethics, Hobbes's Leviathan, Kant's Groundings for a Metaphysics of Morals, and Rawls's A Theory of Justice), contemporary discussions of particular moral issues, and the science of moral thought. Instructor: Quartz. Hum/P| 41. Knowledge and Reality. 9 units (3-0-6); first, second terms. The theme of this course is the scope and limitations of rational belief and knowledge. Students will examine the nature of reality, the nature of the self, the nature of knowledge, and how we learn about the natural world. Students will be introduced to these issues through selections from some of the world's greatest philosophical works, including Descartes's Meditations, Pascal's Pensées, Hume's Enquiry Concerning Human Understanding, Berkeley's Principles of Human Knowledge, and Kant's Prolegomena to any Future Metaphysics. A variety of more contemporary readings will also be assigned. Instructors: Eberhardt, Hitchcock. Hum/P| 44. Philosophy Through Science Fiction. 9 units (3-0-6); third term. This course will provide a broad introduction to philosophy using examples from science fiction to make abstract philosophical problems vivid. Topics may include: time travel and the reality of the past and future; teleportation and what makes someone the same person over time; fictional tales of extended deception and Cartesian skepticism; futuristic utopias and the question of what make a life good; the moral status of aliens and animals; intelligent robots and the relation between Courses mind and body; parallel universes and the philosophical foundations of quantum physics. Hum/P| 45. Ethics & Al. 9 units (3-0-6); first term. How do we reconcile the possibilities of modern machine learning with ethical and moral demands of fairness, accountability and transparency? This course will take a case study-based approach to the challenges at the interface of algorithms and human values. By exploring existing debates on algorithmic bias, explainable Al and data ownership, students will be exposed to the relevance of ethical systems of thought to modern social questions. Instructor: Pham. Hum/VC 48. Ways of Seeing. 9 units (3-0-6); first term. "The knowledge of photography is just as important as that of the alphabet," wrote artist László Moholy-Nagy in 1928. "The illiterate of the future," he warned, "will be the person ignorant of the use of the camera as well as the pen." Almost a century later, this pronouncement rings as true as ever in a world so profoundly shaped not just by photography but also films, advertisements, and video games, cartoons and comics, molecular graphics and visual models. In this course we will explore how visual culture shapes our lives and daily experiences, and we will learn to find wonder in its rich details. In doing so, we will develop the visual literacy that Moholy-Nagy envisioned: essential skills in reading, analyzing, discussing, and writing about visual materials and their circulation through the physical and virtual networks that structure our world. Not offered 2022-23. Instructor: Jacobson. Hum/VC 50. Introduction to Film. 9 units (3-0-6); first, third terms. This course examines the historical development of film as a popular art and entertainment medium from the 1880s to the present, with a focus on the American and European contexts. Students will learn how to watch a film - how to pay attention to significant visual details and to the ways films construct meaning from the language of images - and will develop the skills to write fluently about what they see. The course covers some of the most influential genres and movements from the earliest actuality films, through the French New Wave, to the Disney/Marvel Universe. Films covered may include short comedies from Charlie Chaplin and Buster Keaton, M, It Happened One Night, The Seven Samurai, The Battle of Algiers, and Black Panther. Instructor: Jurca. Hum/VC 51. Icons and Iconoclasm. 9 units (3-0-6); second term. How does something - an image, a person, a thing, an idea - become iconic? Drawing from the worlds of art and film, advertising and PR, science and technology, politics and propaganda, this course explores what makes certain people, places, and things "icons." To do so, we will first deploy a range of methods for closely analyzing images as signs and symbols, including the practice art historians term "iconology." We will then examine histories of how objects have circulated through culture - from newspapers and magazines to postcards, jpegs, and memes - and thereby become ubiquitous features of everyday experience. Finally, we will consider iconoclasm, the destruction of icons, and the beliefs and Humanities 689 690 logics behind powerful interdictions against visual representation. Students will leave the course with a stronger understanding of image power as well as foundational tools of visual and media literacy. Not offered 2022-23. Instructor: Jacobson. Hum/VC 52. The Legacy of the Mexican School. 9 units (3-0-6); third term. Artists in the United States greatly admired the Mexican muralists and printmakers of the 20th century. Respected as much for their cultural politics as their artworks, the Mexican School attracted generations of Black and Latino artists who visited, studied, and worked in Mexico. In the legends and practices of the Mexican School, American artists found models for generating self-defined cultural and artistic practices unavailable to them in the United States. This international exchange generated a transnational and decolonial aesthetic tradition. The course begins with the major themes of Mexican printmaking and muralism; follows Mexican and U.S. artists as they travel between their respective countries throughout the 20th century; and concludes with the legacy of the Mexican School on contemporary public art practices. Local artists will be invited to speak with the class. Instructor: Decemvirale. Hum 59. Special Topics in Humanities. 9 units (3-0-6); offered by announcement.

This seminar course will explore and discuss the unique intersection of environmental racism, environmental justice, and academia. Course material will primarily feature readings and videos on a case study-like basis and focus on bringing conversations typically had in humanities, social sciences and activism to the bio and geosciences. Topics will center around two primary approaches: an "outward-facing" component that looks at environmental racism through the lens of various activisms, and an "inward-facing" component addressing the biases/malpractices broadly employed in the biological and geosciences, as well as the apparent moral dilemmas of decisions involving multiple stakeholders. Out of class work will largely be based on assigned readings, some multimedia presentations, and occasional writings and thought exercises. This course is taught concurrently with Ge/ESE/Bi 248 and can only be taken once, as Hum 61 or Ge/ESE/Bi 248. Instructor: Mushkin. Hum 75. Selected Topics in Humanities.

Prerequisites: Ma 3/103 or ACM/EE/DS 116, Ec 122 or IDS/ACMICS 157 or Ma 112 a. Fundamentally, this course is about making arguments with numbers and data. Data analysis for its own sake is often quite boring, but becomes crucial when it supports claims about the world. A convincing data analysis starts with the collection and cleaning of data, a thoughtful and reproducible statistical analysis of it, and the graphical presentation of the results. This course will provide students with the necessary practical skills, chiefly revolving around statistical computing, to conduct their own data analysis. This course is not an introduction to statistics or computer science. I assume that students are familiar with at least basic probability and statistical concepts up to and including regression.

Instructor: Lu. Mu 53. Listening to Music. 9 units (3-0-6); second term. Most of the music we encounter can be thought of as the organization of a very limited set of tones into distinct patterns of repetition, and it has been this way for hundreds, if not thousands, of years. And yet, music has come to mean infinitely more than its sonic surface: we study great works of music like we do great works of literature and art; we use our musical preferences to convey our social and political identities; we expect - and technology has enabled - our public and private spaces to be saturated in music; and certain musical works possess such power that they are sometimes altered, if not banned outright. But how has music acquired all of these meanings? How does it communicate? What is it that we are listening to when we are listening to music? In addition to serving as an introduction to the academic study of music, this course aims to deepen our musical appreciation and understanding by critically examining listening habits of the past and present. Knowledge of Western music notation and harmony is helpful but not required; the basics will be reviewed as needed. Instructor: Lu. Mu 55.

This course explores the creative craft of envisioning a world as a system of relations, while critically examining the ethical implications of how its actors and elements are represented - and what (or who) is left out. We will take an interdisciplinary approach through lectures and readings in art, theory, and fiction. We will analyze forms of worldbuilding across disciplines and media - from novels to experimental film to architectural renderings to PowerPoint presentations. How do artists build and represent an imagined world through landscapes, seasons, sensory capacities of bodies, and relations of gender, race, and political conflict? How can the social structures in artworks reflect and elaborate upon the worlds we know? We will also draw inspiration from the work of visionary Black science fiction author Octavia Butler, whose archive is held by the Courses Huntington Library. Students will create projects to build their own worlds through writing and visualizations across media of their choice (sculpture, drawing, photography, video, and other creative technologies). Instructor: Berrigan. VC 60. Art/Media. Units to be determined by the instructor; offered by announcement. A practice-based course taught by a visiting artist in residence.

Instructor: Mushkin. En/VC 129. Literature/Photography/Facticity. 9 units (3-0-6); For course description, see English VC 130. Surveillance. 9 units (3-0-6); first term. This course examines surveillance, one of the defining features of twenty-first-century life, with wide-ranging implications (from intelligence gathering and biometrics to social media and contemporary art), and a key point of intersection between modern technology and visual culture. Though it applies more broadly, the concept of "surveillance," from the Latin vigilare ("to watch") and the French surveiller ("to watch over"), originated in practices of looking and observation that still define many of its most significant Courses practices today. Building on these etymological roots, we will treat surveillance as, first and foremost, a visual practice and survey the longer history of surveillance (and counter-surveillance) techniques as well as the theories that have emerged to describe its social effects, moral and ethical stakes, and changing legal status. Not offered 2022-23. Instructor: Jacobson. En/VC 135. Dickens's London. 9 units (3-0-6); For course description, see English VC 150. Art Museum Futures. 9 units (3-0-6); second term. The late 1960s saw the beginning of a movement in which several generations of artists investigated and deconstructed the customs and institutions of art. Institutional critique, as it would come to be known, challenged the promises and putative neutrality of public art museums. Following several decades of criticism the question remains unanswered: can the public art museum become a democratic institution? This course explores the ongoing debates around race, ethnicity, objectivity, subjectivity and cultural authority in contemporary museology. We will begin with the Enlightenment origins of the European art museum and its deployment within the United States; we will consider the artistic interventions that exposed its biases and eurocentrism, as well as the emergence of culturally-specific arts institutions and contemporary efforts at decolonization. Relying on decolonial and ethnic studies scholars, we will develop a critical framework for understanding the historical pathways that led to the National Museum of African American History and Culture and the upcoming Latino Smithsonian Museum. We will conclude with a deep dive into a radical museum model: Noah Purifoy's "Outdoor Desert Art Museum of Assemblage Sculpture". Not offered 2022-23. Instructor: Decemvirale. L/VC 153. Refugees and Migrants' Visual and Textual Representations. 9 units (3-0-6); For course description, see Languages VC 159. Los Angeles as Artwork: Dia de los Muertos. 9 units (3-0-6); third term. Covering a broad range of environments and visual cultures, this upper division course explores the history of Los Angeles through a decolonial and borderlands framework. The seminar begins with Tongva/Gabrielino history and traces the transformations and remapping of the land by Spanish, Catholic missionary, Mexican and Anglo-American empires. Relying on the Catholic Mexican Indigenous and Chicano ritual, Día de los Muertos, as a touchstone, the course investigates how aesthetic projects in Los Angeles have resisted the colonization of space, time, and being. We will cover topics including modernity/coloniality, conversion and assimilation, the politics of public art, and the outstanding role race has played in shaping the cultural landscape. Students will learn to analyze a contemporary opera, historic maps, murals, sculpture, socially-engaged art performances and photographs. Students will be tasked with generating small-scale collages and drawings in response to historic and contemporary themes. Local cultural workers and artists will be invited to speak with the class.

The New Hollywood. 9 units (3-0-6); For course description, see English VC/H/HPS 164. Fashion and Waste. 9 units (3-0-6); second term. Before the Industrial Revolution, new clothes were few and far between. By the early 1800s, new industrial recycling processes enabled wool rags to be reprocessed into new suits, and for the first time the working class gained access to 'Sunday finery.' Dressing better meant a chance at increased social mobility. Today we take for granted fast fashion and disposable clothing. This course examines the complex interrelationship among history, technology, and the ways in which we construct our own identities through clothing; visual, textile and other material culture sources will be front and center. Students will dig into their own closets, memories, and dreams. Not offered 2022-23. Instructor: Shell. VC 169. The Arts of Dynastic China. 9 units (3-0-6); third term. A survey of the development of Chinese art in which the major achievements in architecture, sculpture, painting, calligraphy, and ceramics will be studied in their cultural contexts from prehistory through the Manchu domination of the Qing Dynasty (1644-1911).

Arts of Buddhism. 9 units (3-0-6); third term. An examination of the impact of Buddhism on the arts and cultures of India, Southeast Asia, China, Korea, and Japan from its earliest imagery in the 4th century B.C.E. India through various doctrinal transformations to the Zen revival of 18th-century Japan. Select monuments of Buddhist art, including architecture, painting, sculpture, and ritual objects, will serve as focal points for discussions on their aesthetic principles and for explorations into the religious, social, and cultural contexts that underlie their creation. Not offered 2022-23. Instructor: Wolfgram. VC/En 172. Heritage Studies. 9 units (3-0-6); first term. What makes an old building, artifact, or custom "historic"? Which historic things are worth preserving? This course explores the aesthetic, political, social, and environmental dimensions of cultural heritage. We will examine the narratives and values associated with heritage conservation at the local Courses level as well as within national and global contexts. From Caltech's own campus and the Watts Towers, to the national parks, UNESCO World Heritage Sites, and the culinary legacy of the Atlantic slave trade, our class will grapple with the theories, practices, and debates as they determine what gets preserved and which stories get told. Readings/screenings will be supplemented with field trips to heritage sites in Pasadena and Los Angeles. Instructor: Jurca. VC 175. The Art of Science. 9 units (3-0-6); second term. This course examines the frequent and significant encounters between what chemist/novelist C.P. Snow famously dubbed the "two cultures"-the sciences and the humanities-with an emphasis on forms and practices of visual culture that blur the boundaries between science, technology, and art. What role, we will ask, have visual culture and visuality played in the construction of scientific knowledge? Taking a broad historical and geographical approach, we will explore topics including representations of science and technology in the arts and popular culture; the use of photography, illustration, and visualization in the sciences; histories of visuality and visual devices; and the everyday visual practices of scientific inquiry. Not offered 2022-23. Instructor: Jacobson. H/HPS/VC 185. Angels and Monsters: Cosmology, Anthropology, and the Ends of the World. 9 units (3-0-6); For course description, see History H/HPS/VC 186.
