Requirements for a Doctorate in Physics

An advanced degree in physics at Caltech is contingent upon an extensive research achievement. Students in the program are expected to join a research group, carry out independent research, and write publications for peer-reviewed journals as well as a thesis. The thesis work proposed to a Caltech candidacy committee then presented and evaluated by a Caltech thesis committee in a public defense. Initially, students are required to consolidate their knowledge by taking advanced courses in at least three subfields of physics. Students must also pass a written candidacy exam in both classical physics and quantum mechanics in order to progress into the research phase of the degree.

Graduates of our program are expected to have extensive experience with modern research methods, a broad knowledge of contemporary physics, and the ability to perform as independent researchers at the highest intellectual and technical levels.

The PhD requirements are below and are also available in the Caltech Catalog, Section 4: Information for Graduate Students .

Plan of Study

The plan of study is the set of courses that a student will take to complete the Advance Physics Requirement and any courses needed as preparation to pass the Written Candidacy Exams (see below). Any additional courses the student plans to take as part of their graduate curriculum may be included in the plan of study but are not required. Students should consult with their Academic Advisor on their Plan of Study and discuss any exception or special considerations with the Option Representative. 

Log in to REGIS and navigate to the Ph. D. Candidacy Tab of your Graduate Degree Progress page. Add you courses into the Plan of Study section. When complete, click the "Submit Plan of Study to Option Rep" button. This will generate a notice to the Option Rep to approve your plan of study. Once you complete the courses in the Plan of Study, the Advanced Physics Requirement is completed.

Written Candidacy Exams

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, so proficiency will be tested by 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 and Ph 125. In addition, the class Ph 201 will provide additional problem solving training that matches the basic physics requirement.

Exam I: Classical Mechanics and Electromagnetism       Topics include: TBA

Exam 2: Quantum Mechanics, Statistical Mechanics and Thermodynamics      Topics include: TBA

Both exams are offered twice each year (July and October) Email  [email protected]  to sign up

Nothing additional. Sign up for the exam by emailing Mika Walton. The Student Programs Office will update your REGIS record once you pass the exams.

Advanced Physics Requirement

Students must 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. Many courses in physics and related areas may be allowed to count toward the Advanced Physics requirements.  Below are some popular examples.  Contact the Physics Option Representative to find out if any particular course not listed here can be used for this requirement.

Nothing additional. Once you complete the courses in your approved Plan of Study, the Advanced Physics Requirement is complete.

Oral Candidacy Exam

The Oral Candidacy Exam is primarily a test of the candidate's suitability for research in his or her chosen field. Students should consult with the executive officer to assemble their oral candidacy committee. The chair of the committee should be someone other than the research adviser.

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.

See also the Physics Candidacy FAQs

After the exam, your committee members will enter their result and any comments they may have. Non-Caltech committee members are instructed to send their results and comments to the physics graduate office who will enter the information on their behalf. Once all "pass" results have been entered, the Option Rep will be prompted to recommend you for admission to candidacy. The recommendation goes to the Dean of Graduate Studies who has the final approval to formally admit you to candidacy.

Teaching Requirement

Thesis advisory committee (tac).

After the oral candidacy exam, students will hold annual meetings with their Thesis Advisory Committee (TAC). The TAC will review the research progress and provide feedback and guidance towards completion of the degree. Students should consult with the executive officer to assemble their oral candidacy committee and 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 should be 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 and the Option Rep.

PhD Program

A PhD degree in Physics is awarded in recognition of significant and novel research contributions, extending the boundaries of our knowledge of the physical universe. Selected applicants are admitted to the PhD program of the UW Department of Physics, not to a specific research group, and are encouraged to explore research opportunities throughout the Department.

Degree Requirements

Typical timeline, advising and mentoring, satisfactory progress, financial support, more information.

Applicants to the doctoral program are expected to have a strong undergraduate preparation in physics, including courses in electromagnetism, classical and quantum mechanics, statistical physics, optics, and mathematical methods of physics. Further study in condensed matter, atomic, and particle and nuclear physics is desirable. Limited deficiencies in core areas may be permissible, but may delay degree completion by as much as a year and are are expected to remedied during the first year of graduate study.

The Graduate Admissions Committee reviews all submitted applications and takes a holistic approach considering all aspects presented in the application materials. Application materials include:

• Resume or curriculum vitae, describing your current position or activities, educational and professional experience, and any honors awarded, special skills, publications or research presentations.
• Statement of purpose, one page describing your academic purpose and goals.
• Personal history statement (optional, two pages max), describing how your personal experiences and background (including family, cultural, or economic aspects) have influenced your intellectual development and interests.
• Three letters of recommendation: submit email addresses for your recommenders at least one month ahead of deadline to allow them sufficient time to respond.
• Transcripts (unofficial), from all prior relevant undergraduate and graduate institutions attended. Admitted applicants must provide official transcripts.
• English language proficiency is required for graduate study at the University of Washington. Applicants whose native language is not English must demonstrate English proficiency. The various options are specified at: https://grad.uw.edu/policies/3-2-graduate-school-english-language-proficiency-requirements/ Official test scores must be sent by ETS directly to the University of Washington (institution code 4854) and be received within two years of the test date.

For additional information see the UW Graduate School Home Page , Understanding the Application Process , and Memo 15 regarding teaching assistant eligibility for non-native English speakers.

The GRE Subject Test in Physics (P-GRE) is optional in our admissions process, and typically plays a relatively minor role.  Our admissions system is holistic, as we use all available information to evaluate each application. If you have taken the P-GRE and feel that providing your score will help address specific gaps or otherwise materially strengthen your application, you are welcome to submit your scores. We emphasize that every application will be given full consideration, regardless of whether or not scores are submitted.

Applications are accepted annually for autumn quarter admissions (only), and must be submitted online. Admission deadline: DECEMBER 15, 2024.

Department standards

Course requirements.

Students must plan a program of study in consultation with their faculty advisor (either first year advisor or later research advisor). To establish adequate breadth and depth of knowledge in the field, PhD students are required to pass a set of core courses, take appropriate advanced courses and special topics offerings related to their research area, attend relevant research seminars as well as the weekly department colloquium, and take at least two additional courses in Physics outside their area of speciality. Seeking broad knowledge in areas of physics outside your own research area is encouraged.

The required core courses are:

In addition, all students holding a teaching assistantship (TA) must complete Phys 501 / 502 / 503 , Tutorials in Teaching Physics.

Regularly offered courses which may, depending on research area and with the approval of the graduate program coordinator, be used to satisfy breadth requirements, include:

• Phys 506 Numerical Methods
• Phys 555 Cosmology & Particle Astrophysics
• Phys 507 Group Theory
• Phys 557 High Energy Physics
• Phys 511 Topics in Contemporary Physics
• Phys 560 Nuclear Theory
• Phys 520 Quantum Information
• Phys 564 General Relativity
• Phys 550 Atomic Physics
• Phys 567 Condensed Matter Physics
• Phys 554 Nuclear Astrophysics
• Phys 570 Quantum Field Theory

Graduate exams

Master's Review:   In addition to passing all core courses, adequate mastery of core material must be demonstrated by passing the Master's Review. This is composed of four Master's Review Exams (MREs) which serve as the final exams in Phys 524 (SM), Phys 514 (EM), Phys 518 (QM), and Phys 505 (CM). The standard for passing each MRE is demonstrated understanding and ability to solve multi-step problems; this judgment is independent of the overall course grade. Acceptable performance on each MRE is expected, but substantial engagement in research allows modestly sub-par performance on one exam to be waived. Students who pass the Master's Review are eligible to receive a Master's degree, provided the Graduate School course credit and grade point average requirements have also been satisfied.

General Exam:   Adequate mastery of material in one's area of research, together with demonstrated progress in research and a viable plan to complete a PhD dissertation, is assessed in the General Exam. This is taken after completing all course requirements, passing the Master's Review, and becoming well established in research. The General Exam consists of an oral presentation followed by an in-depth question period with one's dissertation committee.

Final Oral Exam:   Adequate completion of a PhD dissertation is assessed in the Final Oral, which is a public exam on one's completed dissertation research. The requirement of surmounting a final public oral exam is an ancient tradition for successful completion of a PhD degree.

Graduate school requirements

Common requirements for all doctoral degrees are given in the Graduate School Degree Requirements and Doctoral Degree Policies and Procedures pages. A summary of the key items, accurate as of late 2020, is as follows:

• A minimum of 90 completed credits, of which at least 60 must be completed at the University of Washington. A Master's degree from the UW or another institution in physics, or approved related field of study, may substitute for 30 credits of enrollment.
• At least 18 credits of UW course work at the 500 level completed prior to the General Examination.
• At least 18 numerically graded UW credits of 500 level courses and approved 400 level courses, completed prior to the General Examination.
• At least 60 credits completed prior to scheduling the General Examination. A Master's degree from the UW or another institution may substitute for 30 of these credits.
• A minimum of 27 dissertation (or Physics 800) credits, spread out over a period of at least three quarters, must be completed. At least one of those three quarters must come after passing the General Exam. Except for summer quarters, students are limited to a maximum of 10 dissertation credits per quarter.
• A minimum cumulative grade point average (GPA) of 3.00 must be maintained.
• The General Examination must be successfully completed.
• A thesis dissertation approved by the reading committee and submitted and accepted by the Graduate School.
• The Final Examination must be successfully completed. At least four members of the supervisory committee, including chair and graduate school representative, must be present.
• Registration as a full- or part-time graduate student at the University must be maintained, specifically including the quarter in which the examinations are completed and the quarter in which the degree is conferred. (Part-time means registered for at least 2 credits, but less than 10.)
• All work for the doctoral degree must be completed within ten years. This includes any time spend on leave, as well as time devoted to a Master's degree from the UW or elsewhere (if used to substitute for credits of enrollment).
• Pass the required core courses: Phys 513 , 517 , 524 & 528 autumn quarter, Phys 514 , 518 & 525 winter quarter, and Phys 515 , 519 & 505 spring quarter. When deemed appropriate, with approval of their faculty advisor and graduate program coordinator, students may elect to defer Phys 525 , 515 and/or 519 to the second year in order to take more credits of Phys 600 .
• Sign up for and complete one credit of Phys 600 with a faculty member of choice during winter and spring quarters.
• Pass the Master's Review by the end of spring quarter or, after demonstrating substantial research engagement, by the end of the summer.
• Work to identify one's research area and faculty research advisor. This begins with learning about diverse research areas in Phys 528 in the autumn, followed by Phys 600 independent study with selected faculty members during winter, spring, and summer.
• Pass the Master's Review (if not already done) by taking any deferred core courses or retaking MREs as needed. The Master's Review must be passed before the start of the third year.
• Settle in and become fully established with one's research group and advisor, possibly after doing independent study with multiple faculty members. Switching research areas during the first two years is not uncommon.
• Complete all required courses. Take breadth courses and more advanced graduate courses appropriate for one's area of research.
• Perform research.
• Establish a Supervisory Committee within one year after finding a compatible research advisor who agrees to supervise your dissertation work.
• Take breadth and special topics courses as appropriate.
• Take your General Exam in the third or fourth year of your graduate studies.
• Register for Phys 800 (Doctoral Thesis Research) instead of Phys 600 in the quarters during and after your general exam.
• Take special topics courses as appropriate.
• Perform research. When completion of a substantial body of research is is sight, and with concurrence of your faculty advisor, start writing a thesis dissertation.
• Establish a dissertation reading committee well in advance of scheduling the Final Examination.
• Schedule your Final Examination and submit your PhD dissertation draft to your reading committee at least several weeks before your Final Exam.
• Take your Final Oral Examination.
• After passing your Final Exam, submit your PhD dissertation, as approved by your reading committee, to the Graduate School, normally before the end of the same quarter.

This typical timeline for competing the PhD applies to students entering the program with a solid undergraduate preparation, as described above under Admissions. Variant scenarios are possible with approval of the Graduate Program coordinator. Two such scenarios are the following:

• Students entering with insufficient undergraduate preparation often require more time. It is important to identify this early, and not feel that this reflects on innate abilities or future success. Discussion with one's faculty advisor, during orientation or shortly thereafter, may lead to deferring one or more of the first year required courses and corresponding Master's Review Exams. It can also involve taking selected 300 or 400 level undergraduate physics courses before taking the first year graduate level courses. This must be approved by the Graduate Program coordinator, but should not delay efforts to find a suitable research advisor. The final Master's Review decision still takes place no later than the start of the 3rd year and research engagement is an important component in this decision.
• Entering PhD students with advanced standing, for example with a prior Master's degree in Physics or transferring from another institution after completing one or more years in a Physics PhD program, may often graduate after 3 or 4 years in our program. After discussion with your faculty advisor and with approval of the Graduate Program coordinator, selected required classes may be waived (but typically not the corresponding Master's Review Exams), and credit from other institutions transferred.
• Each entering PhD student is assigned a first year faculty advisor, with whom they meet regularly to discuss course selection, general progress, and advice on research opportunities. The role of a student's primary faculty advisor switches to their research advisor after they become well established in research. Once their doctoral supervisory committee is formed, the entire committee, including a designated faculty mentor (other than the research advisor) is available to provide advice and mentoring.
• The department also has a peer mentoring program, in which first-year students are paired with more senior students who have volunteered as mentors. Peer mentors maintain contact with their first-year mentees throughout the year and aim to ease the transition to graduate study by sharing their experiences and providing support and advice. Quarterly "teas" are held to which all peer mentors and mentees are invited.
• While academic advising is primarily concerned with activities and requirements necessary to make progress toward a degree, mentoring focuses on the human relationships, commitments, and resources that can help a student find success and fulfillment in academic and professional pursuits. While research advisors play an essential role in graduate study, the department considers it inportant for every student to also have available additional individuals who take on an explicit mentoring role.
• Students are expected to meet regularly, at a minimum quarterly, with their faculty advisors (either first year advisor or research advisor).
• Starting in the winter of their first year, students are expected to be enrolled in Phys 600 .
• Every spring all students, together with their advisors, are required to complete an annual activities report.
• The doctoral supervisory committee needs to be established at least by the end of the fourth year.
• The General Exam is expected to take place during the third or fourth year.
• Students and their advisors are expected to aim for not more than 6 years between entry into the Physics PhD program and completion of the PhD. In recent years the median time is close to 6 years.

Absence of satisfactory progress can lead to a hierarchy of actions, as detailed in the Graduate School Memo 16: Academic Performance and Progress , and may jeopardize funding as a teaching assistant.

The Department aims to provide financial support for all full-time PhD students making satisfactory progress, and has been successful in doing so for many years. Most students are supported via a mix teaching assistantships (TAs) and research assistantships (RAs), although there are also various scholarships, fellowships, and awards that provide financial support. Teaching and research assistanships provide a stipend, a tuition waiver, and health insurance benefits. TAs are employed by the University to assist faculty in their teaching activities. Students from non-English-speaking countries must pass English proficiency requirements . RAs are employed by the Department to assist faculty with specified research projects, and are funded through research grants held by faculty members.

Most first-year students are provided full TA support during their first academic year as part of their admission offer. Support beyond the second year is typically in the form of an RA or a TA/RA combination. It is the responsibility of the student to find a research advisor and secure RA support. Students accepting TA or RA positions are required to register as full-time graduate students (a minimum of 10 credits during the academic year, and 2 credits in summer quarter) and devote 20 hours per week to their assistantship duties. Both TAs and RAs are classified as Academic Student Employees (ASE) . These positions are governed by a contract between the UW and the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW), and its Local Union 4121 (UAW).

Physics PhD students are paid at the "Assistant" level (Teaching Assistant or Research Assistant) upon entry to the program. Students receive a promotion to "Associate I" (Predoctoral Teaching Associate I or Predoctoral Research Associate I) after passing the Master's Review, and a further promotion to "Associate II" (Predoctoral Teaching Associate II or Predoctoral Research Associate II) after passing their General Examination. (Summer quarter courses, and summer quarter TA employment, runs one month shorter than during the academic year. To compendate, summer quarter TA salaries are increased proportionately.)

Physics, PhD

Zanvyl krieger school of arts and sciences, admission requirements.

To obtain admission, a student is expected to submit evidence that they have a good chance to succeed. 

A complete application will include:

• Statement of purpose. We look for a thoughtful, well-written statement that shows the ability to overcome challenges, dedication to attain chosen goals, a capacity for creativity, an understanding of physics and/or astronomy, and any other indication of potential for research.
• Three letters of recommendation. Recommendation letters should help us evaluate your capacity for research, the most important criterion for admission.
• Transcripts of all previous work. Transcripts submitted with the application may be unofficial transcripts. Successful applicants who accept the offer of admission must supply an official transcript before they can begin the PhD program at JHU. In the case of students in the final year of their bachelors program, the official transcript must show completion of all coursework required for the degree.
• TOEFL or IELTS for international students. A reproduction is acceptable. Johns Hopkins prefers a minimum score of 600 (paper-based) or 250 (computer-based) or 100 (Internet-based) on the Test of English as a Foreign Language (TOEFL).
• $75 non-refundable application fee. The application fee may be waived .

Note: submission of General GRE and Physics GRE scores is optional.

Successful applicants applying in the last year of their Bachelor’s program will need to demonstrate the completion of their Bachelor’s degree program before they can begin the Ph.D. program at JHU.

Program Requirements

The Ph.D. program has strong emphasis on early and active involvement in graduate research. Thus, students are required to have a research advisor and file a research summary every semester they are enrolled in the program, starting with the first one. Furthermore, students must complete the required courses with a grade of B- or better; the coursework is typically done over the first two years. In the beginning of the second year, students complete the research examination, and in the beginning of the third year – the University’s Graduate Board Oral examination, both of which are based on completed or proposed research. During the first two years, students are typically involved in introductory research projects, which may or may not be related to their thesis work, and sometimes work with several different advisors, but they must identify (and have an agreement with) a thesis advisor no later than the beginning of their third year in the program, after which point students focus on their thesis research. The thesis is to be completed by no later than the end of the 6th year, ending with an oral presentation of the thesis to a faculty committee.

Course Requirements

Ph.d. in physics.

Students must complete the following courses:

Ph.D. in Astronomy and Astrophysics

Students in both programs must receive at least a B- in each required course, or they will be required to retake the specific course once more and pass it. Graduate courses may only be retaken once.

The department offers a wide range of graduate physics, astrophysics, mathematical methods and statistics classes, and while only five are required, the students are encouraged to use the flexibility of the graduate program and the available classes to design programs of study that best prepare them for their chosen area of research. In addition to the required courses listed above, below is the list of the graduate courses that have been taught in recent years:

Research and Advising

The principal goal of graduate study is to train the student to conduct original research. Therefore, physics and astronomy graduate students at Johns Hopkins are involved in research starting in their first semester in the program.

First and Second-Year Research Requirement

By the end of September, the student chooses their first research advisor among the professorial faculty and starts working on the first-semester research project. If the proposed research advisor does not hold a primary appointment as a tenure-track or research faculty member in the Department of Physics and Astronomy, the form must be co-signed by a PHA faculty member, who will provide mentorship  (relevant department faculty members list) . This requirement holds for all semesters of research. The first-semester project continues through intersession in January. The spring-semester research project continues until the end of the spring semester. The summer semester lasts from June through August. Students may continue with one advisor through the entire first year, or they may choose to cycle through several different research advisers from one semester to the next.

This system of semester projects continues during the first two years of the program, when students also complete required coursework. The nature of these first- and second-year research projects varies from student to student, from advisor to advisor and from one sub-field of physics to another. Some may be self-contained research projects that lead to published scientific papers and may or may not be related to the thesis research in later years. Others may comprise reading or independent-study projects to develop background for subsequent research. In other cases, they may be first steps in a longer-term research project.

This system accommodates both the students who have chosen the direction of their thesis work before graduate school and those who would like to try a few different things before committing to a long-term project. As students get more familiar with the department and the research opportunities, they zero in on their thesis topic and find a thesis advisor. This may happen any time during the first two years, and students are required to find a thesis advisor by the beginning of the third year.

Thesis Research and Defense

Securing a mutual agreement with a thesis advisor is one of the most important milestones of our graduate program. Students must find a thesis advisor and submit the thesis advisor form before the first day of their 3rd year. The form represents a long-term commitment and serious efforts in planning and communication between the student and the advisor. If the proposed thesis advisor does not hold a primary appointment as a tenure-track or research faculty member in the Department of Physics and Astronomy, the form must be co-signed by a PHA faculty member, who will serve as the departmental advisor of record (relevant department faculty members list) . 

After the student chooses a thesis advisor, the student forms their Thesis Committee consisting of three faculty members in the Dept. of Physics and Astronomy (PHA). At least two should be tenure track faculty with primary appointments in PHA. An external advisor may be added as the fourth member of the committee. These committees function as extended advisory bodies; students have the opportunity to discuss their progress and problems with several faculty. They also conduct one formal annual review of each student’s progress.

Research leading to the dissertation can be carried out not only within the Department of Physics and Astronomy, but with appropriate arrangements, either partly or entirely at other locations if necessitated by the project goals. At the conclusion of thesis research, the student presents the written dissertation to the faculty committee and defends the thesis in an oral examination.

Requirements for the M.A. Degree

Although the department does not admit students who intend to pursue the master’s degree exclusively, students in the department’s Ph.D. program and students in other Ph.D. programs at Johns Hopkins may apply to fulfill the requirements for the M.A. degree in the Department of Physics and Astronomy. Students from other JHU departments must seek approval from their home department and from the Department of Physics and Astronomy.

Before beginning their M.A. studies, students must have mastered the undergraduate physics material covered by the following courses:

Students must receive at least a B- in each required course, or they will be required to retake the specific course once more and pass it.  Graduate courses may only be retaken once.

Courses taken elsewhere may qualify at the discretion of the Graduate Program Committee (normally this requirement is satisfied by the Ph.D.-track students before they arrive at JHU as they have completed a B.A. or B.Sci. in Physics at another institution).

To qualify for the M.A. degree in Physics, students must complete eight one-semester 3-credit graduate-level courses in the Department of Physics and Astronomy and pass the departmental research exam. For the M.A. degree in Astronomy, students must complete eight one-semester 3-credit graduate-level courses in the Department of Physics and Astronomy, plus the seminar “Language of Astrophysics” and pass the departmental research exam. The student must receive a grade of B- or above in each of the courses; graduate courses can be retaken once in case of failure.

Of the eight one-semester courses, four must be the core courses listed above in the Ph.D. requirements and two must be Independent Graduate Research courses. The remaining two course requirements for the M.A. degree may be fulfilled either by 3-credit graduate electives or by additional Independent Graduate Research. The research courses must include an essay or a research report supervised and approved by a faculty member of the Department of Physics and Astronomy.

Under most circumstances students pursuing their Ph.D. qualify for the M.A. degree by the end of their second year if they have taken all four core courses in their discipline at JHU, the “Language of Astrophysics” seminar (for M.A. in Astronomy), four semesters of Independent Graduate Research, and passed the research exam. Graduate courses taken at another institution or in another department at JHU in most cases do not count toward the M.A. requirements (therefore, students who are interested in the M.A. degree, but are planning to waive any graduate courses because they have passed a comparable graduate course at another institution, should discuss their eligibility for the M.A. degree with the Academic Program Administrator as soon as they arrive at JHU). Students should expect that no M.A. requirements can be waived; that the minimal research requirement is two semesters; and that at most one of the core courses can be substituted by another (non-research) graduate course in exceptional circumstances. Any requests for M.A. course substitutions must be made to the Graduate Program Committee at least a year before the expected M.A. degree so that the committee can recommend an appropriate substitution.

What Is It Like to Do a PhD in Physics?

Physics is arguably the most fundamental scientific discipline and underpins much of our understanding of the universe. Physics is based on experiments and mathematical analysis which aims to investigate the physical laws which make up life as we know it.

Due to the large scope of physics, a PhD project may focus on any of the following subject areas:

• Thermodynamics
• Cosmology and Astrophysics
• Nuclear Physics
• Solid State Physics
• Condensed matter Physics
• Particle Physics
• Quantum mechanics
• Computational Physics
• Theoretical Physics
• Electromagnetism and photonics
• Molecular physics
• And many more

Compared to an undergraduate degree, PhD courses involve original research which, creates new knowledge in a chosen research area. Through this you will develop a detailed understanding of applicable techniques for research, become an expert in your research field, and contribute to extending the boundaries of knowledge.

During your postgraduate study you will be required to produce a dissertation which summarises your novel findings and explains their significance. Postgraduate research students also undertake an oral exam, known as the Viva, where you must defend your thesis to examiners.

How Long Does It Take to Get a PhD in Physics?

The typical full-time programme has a course length of 3 to 4 years . Most universities also offer part-time study . The typical part-time programme has a course length of 5 to 7 years.

The typical Physics PhD programme sees PhD students study on a probationary basis during their first year. Admission to the second year of study and enrolment onto the PhD programme is subject to a successful first year review. The format of this review varies across organisations but commonly involves a written report of progress made on your research project and an oral examination.

Additional Learning Modules:

Most Physics PhD programme have no formal requirement for students to attend core courses. There are, however, typically several research seminars, technical lectures, journal clubs and other courses held within the Physics department that students are expected to attend.

Research seminars are commonly arranged throughout your programme to support you with different aspects of your study, for example networking with other postgraduates, guidelines on working with your supervisor, how to avoid bias in independent research, tips for thesis writing, and time management skills.

Doctoral training and development workshops are commonly organised both within and outside of the department and aim to develop students’ transferrable skills (for example communication and team working). Information on opportunities for development that exist within the University and explored and your post doctorate career plans will be discussed.

Lectures run by department staff and visiting scholars on particular subject matters relevant to your research topic are sometimes held, and your supervisor (or supervisory committee) is likely to encourage you to attend.

Typical Entry Requirements:

A UK Physics PhD programme normally requires a minimum upper second-class (2:1) honours undergraduate or postgraduate degree (or overseas equivalent) in physics, or a closely related subject. Closely related subjects vary depending on projects, but mathematics and material sciences are common. Graduate students with relevant work experience may also be considered.

Funded PhD programmes (for examples those sponsored by Doctoral Training Partnerships or by the university school) are more competitive, and hence entry requirements tend to be more demanding.

English Language Requirements:

Universities typically expect international students to provide evidence of their English Language ability as part of their applications. This is usually benchmarked by an IELTS exam score of 6.5 (with a minimum score of 6 in each component), a TOEFL (iBT) exam score 92, a CAE and CPE exam score of 176 or another equivalent. The exact score requirements for the different English Language Qualifications may differ across different universities.

Tips to Improve Your Application:

If you are applying to a Physics PhD, you should have a thorough grasp of the fundamentals of physics, and also appreciate the concepts within the focus of your chosen research topic. Whilst you should be able to demonstrate this through either your Bachelors or Master’s degree, it is also beneficial to also be able to show this through extra-curricular engagement, for example attending seminars or conferences. This will also get across your passion for Physics – a valuable addition to your application as supervisors are looking for committed students.

It is advisable to make informal contact with the project supervisors for any positions you are interested in prior to applying formally. This is a good chance for you to understand more about the Physics department and project itself. Contacting the supervisor also allows you to build a rapport, demonstrate your interest, and see if the project and potential supervisor are a good fit for you. Some universities require you to provide additional evidence to support your application. These can include:

• University certificates and transcripts (translated to English if required)
• Academic CV
• Covering Letter
• English certificate – for international students

How Much Does a Physics PhD Degree Typically Cost?

Annual tuition fees for a PhD in Physics in the UK are approximately £4,000 to £5,000 per year for home (UK) students and are around £22,000 per year for overseas students. This, alongside the standard range in tuition fees that you can expect, is summarised below:

Note: The EU students are considered International from the start of the 2021/22 academic year.

Due to the experimental nature of Physics programmes, research students not funded by UK research councils may also be required to pay a bench fee . Bench fees are additional fees to your tuition, which covers the cost of travel, laboratory materials, computing equipment or resources associated with your research. For physics research students in particular this is likely to involve training in specialist software, laboratory administration, material and sample ordering, and computing upkeep.

What Specific Funding Opportunities Are There for A PhD in Physics?

As a PhD applicant, you may be eligible for a loan of up to £25,700. You can apply for a PhD loan if you’re ordinarily resident in the UK or EU, aged 60 or under when the course starts and are not in receipt of Research Council funding.

Research Councils provide funding for research in the UK through competitive schemes. These funding opportunities cover doctoral students’ tuition fees and sometimes include an additional annual maintenance grant. The Engineering and Physical Sciences Research Council (EPSRC) is a government agency that funds scientific research in the UK. Applications for EPSRC funding should be made directly to the EPSRC, but some Universities also advertise EPSRC funded PhD studentships on their website. The main funding body for Physics PhD studentships is EPSRC’s group on postgraduate support and careers, which has responsibility for postgraduate student support.

The Science and Technology Facilities Council (STFC) funds a large range of projects in Physics and Astronomy. To apply for funding students must locate the relevant project, contact the host institution for details of the postdoctoral researcher they wish to approach and then apply directly to them.

What Specific Skills Will You Get from a PhD in Physics?

PhD doctorates possess highly marketable skills which make them strong candidates for analytical and strategic roles. The following skills in particular make them attractive prospects to employers in research, finance and consulting:

• Strong numerical skills
• Strong analytical skills
• Laboratory experience
• Application of theoretical concepts to real world problems

Aside from this, postgraduate students will also get transferable skills that can be applied to a much wider range of careers. These include:

• Excellent oral and written communication skills
• Great attention to detail
• Collaboration and teamwork
• Independent thinking

What Jobs Can I Get with a PhD in Physics?

The wide range of specialties within Physics courses alone provides a number of job opportunities, from becoming a meteorologist to a material scientist. However, one of the advantages Physics doctorates have over other doctorates is their studies often provide a strong numerical and analytical foundation. This opens a number of career options outside of traditional research roles. Examples of common career paths Physics PostDocs take are listed below:

Academia – A PhD in Physics is a prerequisite for higher education teaching roles in Physics (e.g. University lecturer). Many doctorates opt to teach and supervise students to continue their contribution to research. This is popular among those who favour the scientific nature of their field and wish to pursue theoretical concepts.

PostDoc Researcher – Other postdoctoral researchers enter careers in research, either academic capacity i.e. researching with their University, or in industry i.e. with an independent organisation. Again, this is suited to those who wish to continue learning, enjoy collaboration and working in an interdisciplinary research group, and also offers travel opportunities for international conferences.

Astronomy – Astronomers study the universe and often work with mathematical formulas, computer modelling and theoretical concepts to predict behaviours. A PhD student in this field may work as astrobiologists, planetary geologists or government advisors.

Finance – As mentioned previously, analytical and numerical skills are the backbone of the scientific approach, and the typical postgraduate research programme in Physics is heavily reliant on numeracy. As such, many PostDocs are found to have financial careers. Financial roles typically offer lucrative salaries.

Consulting – Consulting firms often consider a doctoral student with a background in Physics for employment as ideal for consultancy, based on their critical thinking and strategic planning skills.

Many PhD students in the MIT Physics Department incorporate probability, statistics, computation, and data analysis into their research. These techniques are becoming increasingly important for both experimental and theoretical Physics research, with ever-growing datasets, more sophisticated physics simulations, and the development of cutting-edge machine learning tools. The Interdisciplinary Doctoral Program in Statistics (IDPS)  is designed to provide students with the highest level of competency in 21st century statistics, enabling doctoral students across MIT to better integrate computation and data analysis into their PhD thesis research.

Admission to this program is restricted to students currently enrolled in the Physics doctoral program or another participating MIT doctoral program. In addition to satisfying all of the requirements of the Physics PhD, students take one subject each in probability, statistics, computation and statistics, and data analysis, as well as the Doctoral Seminar in Statistics, and they write a dissertation in Physics utilizing statistical methods. Graduates of the program will receive their doctoral degree in the field of “Physics, Statistics, and Data Science.”

Doctoral students in Physics may submit an Interdisciplinary PhD in Statistics Form between the end of their second semester and penultimate semester in their Physics program. The application must include an endorsement from the student’s advisor, an up-to-date CV, current transcript, and a 1-2 page statement of interest in Statistics and Data Science.

The statement of interest can be based on the student’s thesis proposal for the Physics Department, but it must demonstrate that statistical methods will be used in a substantial way in the proposed research. In their statement, applicants are encouraged to explain how specific statistical techniques would be applied in their research. Applicants should further highlight ways that their proposed research might advance the use of statistics and data science, both in their physics subfield and potentially in other disciplines. If the work is part of a larger collaborative effort, the applicant should focus on their personal contributions.

For access to the selection form or for further information, please contact the IDSS Academic Office at  [email protected] .

Required Courses

Courses in this list that satisfy the Physics PhD degree requirements can count for both programs. Other similar or more advanced courses can count towards the “Computation & Statistics” and “Data Analysis” requirements, with permission from the program co-chairs. The IDS.190 requirement may be satisfied instead by IDS.955 Practical Experience in Data, Systems, and Society, if that experience exposes the student to a diverse set of topics in statistics and data science. Making this substitution requires permission from the program co-chairs prior to doing the practical experience.

Grade Policy

C, D, F, and O grades are unacceptable. Students should not earn more B grades than A grades, reflected by a PhysSDS GPA of ≥ 4.5. Students may be required to retake subjects graded B or lower, although generally one B grade will be tolerated.

Unless approved by the PhysSDS co-chairs, a minimum grade of B+ is required in all 12 unit courses, except IDS.190 (3 units) which requires a P grade.

Though not required, it is strongly encouraged for a member of the MIT  Statistics and Data Science Center (SDSC)  to serve on a student’s doctoral committee. This could be an SDSC member from the Physics department or from another field relevant to the proposed thesis research.

Thesis Proposal

All students must submit a thesis proposal using the standard Physics format. Dissertation research must involve the utilization of statistical methods in a substantial way.

PhysSDS Committee

• Jesse Thaler (co-chair)
• Mike Williams (co-chair)
• Isaac Chuang
• Janet Conrad
• William Detmold
• Philip Harris
• Jacqueline Hewitt
• Kiyoshi Masui
• Leonid Mirny
• Christoph Paus

Can I satisfy the requirements with courses taken at Harvard?

Harvard CompSci 181 will count as the equivalent of MIT’s 6.867.  For the status of other courses, please contact the program co-chairs.

Can a course count both for the Physics degree requirements and the PhysSDS requirements?

Yes, this is possible, as long as the courses are already on the approved list of requirements. E.g. 8.592 can count as a breadth requirement for a NUPAX student as well as a Data Analysis requirement for the PhysSDS degree.

If I have previous experience in Probability and/or Statistics, can I test out of these requirements?

These courses are required by all of the IDPS degrees. They are meant to ensure that all students obtaining an IDPS degree share the same solid grounding in these fundamentals, and to help build a community of IDPS students across the various disciplines. Only in exceptional cases might it be possible to substitute more advanced courses in these areas.

Can I substitute a similar or more advanced course for the PhysSDS requirements?

Yes, this is possible for the “computation and statistics” and “data analysis” requirements, with permission of program co-chairs. Substitutions for the “probability” and “statistics” requirements will only be granted in exceptional cases.

For Spring 2021, the following course has been approved as a substitution for the “computation and statistics” requirement:   18.408 (Theoretical Foundations for Deep Learning) .

The following course has been approved as a substitution for the “data analysis” requirement:   6.481 (Introduction to Statistical Data Analysis) .

Can I apply for the PhysSDS degree in my last semester at MIT?

No, you must apply no later than your penultimate semester.

What does it mean to use statistical methods in a “substantial way” in one’s thesis?

The ideal case is that one’s thesis advances statistics research independent of the Physics applications. Advancing the use of statistical methods in one’s subfield of Physics would also qualify. Applying well-established statistical methods in one’s thesis could qualify, if the application is central to the Physics result. In all cases, we expect the student to demonstrate mastery of statistics and data science.
