We welcome applicants with undergraduate training in Astronomy, Physics, and related fields to apply to the UC San Diego Astronomy Ph.D. program!
The UC San Diego Department of Physics offers separate Ph.D. programs in Astronomy and in Physics with a specialization in Astrophysics. The Astronomy Ph.D. provides a focused training in the astronomical sciences, particularly in areas of observational, experimental, and computational/simulation science. The Physics Ph.D. provides a broad training in physics, and may be more suited for students considering theoretical high-energy, astroparticle, and/or cosmological research. Applicants admitted to either the Astronomy Ph.D. or Physics Ph.D. programs complete different course and qualification requirements for their degree, and will receive the degree (Astronomy or Physics) to which they have applied. Graduate students in both programs have equal access to courses, faculty, and research areas across the Physics & Astronomy Department, regardless of degree pursued. Applicants should apply to either the Astronomy Ph.D. program or the Physics Ph.D. program. If admissions personnel believe your application is better suited to the other program, they will reach out to you to consider an application transfer.
UC San Diego requires academic transcripts, including a GPA, from each college-level institution you have attended. Qualified applicants are expected to have sound knowledge of undergraduate physics (mechanics, electromagnetism, thermodynamics, quantum mechanics) and mathematics, and have completed at least one (1) upper-division (junior/senior level) laboratory or computational course. Coursework and research experience in Astronomy is desirable but not required. You must also satisfy all requirements for graduate admissions set by UC San Diego's Graduate Division.
The GRE Physics exam is not required for admission to the Astronomy Ph.D. program, and the general GRE is currently under review to be waived. Applicants may submit Physics GRE scores as optional elements of their application, and these will be considered within the scope of academic preparation in our holistic review. Applicants who do not submit scores will not be penalized in any way. To learn more about why GRE scores are optional for this program, see Miller et al. (2019).
A test of English language proficiency is required for international applicants whose native language is not English and who have not studied full-time for one uninterrupted academic year at a university-level institution in which English is the language of instruction and in a country where English is a dominant language. The English language proficiency requirement may be satisfied by completing one of the following:
Note that international Students whose native language is not English will be required to demonstrate English language proficiency before they may serve as teaching assistants (TAs).
At least three (3) letters of recommendation are required, and up to five (5) letters of recommendation can be submitted. Letter writers may reflect a mix of backgrounds (e.g., academic or industry), but at least two (2) letter writers should be qualified to evaluate your academic achievements, training, and ability to carry out graduate-level research. Be sure to reach out to your letter writers early so that they have plenty of time to complete their recommendation before the application deadline.
You may upload an optional one (1) page CV/resume summarizing your academic preparation, research experience, technical skills, accomplishments/awards, leadership activities, and professional references. A CV template created by Alaina G. Levine by can be found at the Physics Today Jobs website.
The statement of purpose, no longer than 2 pages, allows your reviewers to learn about who you are as an individual, your goals as they pertain to a Ph.D. program, and your potential for graduate study and research. Be sure to describe in your statement of purpose (1) how your career goals and personal background inform your decision to pursue a Ph.D. in Astronomy; (2) your core research goals and how they align with the research and faculty at UC San Diego; and (3) any evidence that supports your potential as a graduate researcher. Be sure to highlight any prior research experiences and outcomes, employment or internships experiences, technical skills, and/or academic coursework that supports your application. The Statement of Purpose can also be used to address any potential weaknesses in your application portfolio (e.g., low course grades, lack of research experience).
We recognize that many applicants have had disrupted or impacted educational experiences during the ongoing COVID-19 pandemic. The graduate application provides an opportunity to describe how COVID-19 has impacted your educational experience in relation to your academic performance or grading scale. For example: “For the spring semester, my university let us take two classes P/NP and I chose this because..” or “For the spring quarter, my college graded all classes as P/NP and we didn’t have an option for a letter grade."
The graduate application includes a section to describe additional education experiences, including those that touch on diversity, equity, and inclusion. There are seven (7) short response (3-5 sentences) sections, any of which may be optionally completed. We strongly recommend applicants complete this section, as several University fellowships are awarded based on these questions.
The graduate application fee for 2022 applications will be:
UC San Diego offers a fee waiver program for participants in several programs, include UCSD STARS and PATHS, UC LEADS, UC-HBCU and UC-HSI initiatives, Cal-Bridge, CAMPARE, the Meyerhoff Scholars program, REU participants, and others. A full list is provided here: https://grad.ucsd.edu/admissions/requirements/application-fee-and-fee-waiver/eligible%20-grad-prep-programs.html. Select your program under the "Other" section of the application, and provide any additional required information to request a fee waiver.
Fee waiver requests can also be made after completion of the full application. Note that all fee waiver requests must be submitted at least one week prior to the application deadline. Your application must be fully submitted for your fee waiver to be processed.
The Admissions Committee evaluates applicants using holistic review, an evidence-based approach that aims to identify potential graduate students that are likely to succeed in astronomy research, regardless of prior research opportunities. You can learn more about how holistic review reduces bias in graduate admissions in Baceló et al. (2020).
UC San Diego offers a number of fellowships to incoming graduate students as a means to increase campus diversity and excellence; see https://grad.ucsd.edu/diversity/incoming-fellowships/index.html.
In addition, AAS Astrobites maintains a list of fellowships and grants for graduate students interested in pursuing Astronomy; see https://astrobites.org/2018/04/27/list-of-major-us-fellowships-for-astronomy-students/.
The Astronomy Ph.D. program is committed to UC San Diego's mission of advancing diversity, equity, and inclusion in higher education. We strongly encourage applicants for traditionally underrepresented groups in higher education and the sciences to apply. We commit to evaluating each applicant's potential for success regardless of socioeconomic background and access to resources and opportunities. The Admissions Committee is trained each year in Implicit Bias mitigation training, and commits to continuous analysis and evaluation of admissions procedures through the lens of equity, inclusion, and bias reduction. The UC San Diego Graduate Division and faculty in the Astronomy Ph.D. program are active participants in the California Consortium for Inclusive Doctoral Education (C-CIDE), a National Science Foundation-funded initiative that aims to create a network of faculty and administrators across doctoral-granting universities to diversify the demographic composition of STEM graduate programs and the scientific workforce in California.
