In addition to the didactic coursework in the first year of the program, students would generally have a three credit hour Research Rotation each semester. The Research Rotations are aimed at matching students into laboratories to complete their thesis research. An additional research rotation in the summer of the first year is allowed if needed. Students must match into a laboratory following the completion of their research rotations to continue in the program. Up to 6 total credit hours of Research Rotations may be counted towards the 70 total credit hours needed for graduation. 

During their second year (and/or beyond at the student’s discretion) students in the Doctor of Philosophy in Medical Physics program will take 12 credit hours of elective coursework. Electives must be courses offered through Washington University in St. Louis and must be at the graduate level (500 or above) to fulfill the course credit, although up to two electives may be at the 400 level with permission of the student’s Faculty Advisor. Although not required, students are encouraged to select electives that provide didactic background for their selected thesis topic. Electives listed as Medical Physics (MP), Physics (Physics), Biomedical Engineering (BME), Electrical and Systems Engineering (ESE), Computer Science and Engineering (CSE), and/or Mathematics (Math) do not need special permission. Any from other departments require permission of the student’s Faculty Advisor.  

Students entering the program with a CAMPEP-accredited MS degree (or equivalent) may receive credit for up to all 22 core Medical Physics credit hours. If they graduated from the Master of Science in Medical Physics program at Washington University in St. Louis, and have taken elective classes while in that program, they may receive credit for those towards the elective requirement. Additionally, these students may waive the Research Rotation requirement, although a minimum of 36 total credit hours of Thesis Research is still required.

Additional Requirements

In addition to the credit hour requirements as described above, students in the program will be expected to:

  • Attend/participate in regularly scheduled academic activities including a monthly, faculty moderated journal club and regular physics seminars.
  • Act as unpaid Assistants in Instruction for two courses within the program after successful completion of their first year in the program.
  • Pass a comprehensive thesis qualifying exam covering the core Medical Physics course topics at the end of the second year.
  • Complete a written and oral thesis proposal following successful completion of the qualifying exam.  While ideally within 6 months following the exam, students who do not complete the proposal within 1.5 years after passing the qualifying exam are placed in academic probation.
  • Complete a written and oral thesis defense at the completion of their thesis research work under the guidance of a Thesis Advisor.

Academic Calendar

Our programs follow the same calendar as the McKelvey School of Engineering. The most up-to-date information for the current academic calendar can be found here: 

Current Academic Calendars 

Academic Dismissal

Students failing to maintain an overall “B” (GPA of 3.0) in courses may be advised to repeat some of the courses. Failure to achieve the minimum required grade in a course for the second time may result in termination from the program. Students may appeal grades by filing an appeal with the Assessment Committee within 30 days of completing a course. Students who do not achieve necessary benchmarks and program requirements in the course of their graduate studies may be placed on probation. Probation will require the Assessment Committee, with input from a student’s Faculty Advisor and Thesis Advisor, to craft a plan and timeline for the student to remediate any issues. Failure to meet the conditions, timeline, and/or benchmarks of the probationary plan may result in termination from the program. The program committee will make final decisions as to matters of dismissal.

Leave of Absence

Should a student require a leave of absence for academic or personal reasons from the PhD in Medical Physics program they must submit a statement in writing to the Program Director for approval. Such statements should include anticipated start and return dates as well as a brief description of the reason. Leaves of absence are granted for no more than one year, but in rare occasions may be renewed by the program. Students requiring a personal leave of absence for medical reasons must also submit a letter from their attending physician.
