UC Davis Physics Residency ProgramThe UC Davis CAMPEP-Approved Radiation Oncology Physics Residency Program is a two-year program designed for individuals at a Masters or Ph.D. level who seek training in clinical radiation oncology physics. 

The physics resident participates directly in the clinical routine, under the supervision of experienced radiation oncology physicists and physicians, while receiving comprehensive training in the areas of external beam planning and treatment delivery, treatment aid design and fabrication, brachytherapy planning and delivery, dose measurement,  radiation treatment machine calibration, special procedures such as image-guided intensity modulated radiation therapy, quality assurance, and radiation safety. 

Graduates of this program will have received sufficient clinical training to prepare them for work as a radiation oncology physicist and certification in the specialty of Therapeutic Radiological Physics by the American Board of Radiology.

The Radiation Oncology Physics Residency Program is an official program within UC Davis Health and administered through the Department of Radiation Oncology. 

The Department is located in the NCI-designated UC Davis Comprehensive Cancer Center and is actively engaged in the advanced clinical and research programs, including image-guided IMRT and VMAT (with motion-management), stereotactic body radiation therapy (SBRT), stereotactic radiosurgery (SRS), image-guided brachytherapy, in vivo dosimetry, and informatics infrastructure development.

The Department has full-member status with the NRG Oncology and has both an ACGME-accredited physician residency training program and a CAMPEP-approved medical physics residency program. There are research affiliations with the UC Davis School of Veterinary Medicine and the UC Davis School of Biomedical Engineering.

Please apply using the American Association of Physicists in Medicine (AAPM) Common Application Program (CAP).

As indicated on the CAP website, you will need the following to apply:

  • Personal information (name, address, contact information)
  • ABR certification status
  • Disclosure of criminal behavior, academic violations, and/or licensure actions
  • Employment history
  • Military service history (if applicable)
  • Education (undergraduate and graduate)
  • Names of 3 references (including one from current advisor or department head)
  • Personal statement (max. 3000 characters) indicating why you want to go into medical physics, and anything else you want to communicate to the applications reviewers (this is instead of a cover letter)
  • Uploaded CV listing awards, publications, presentations, community service and citizenship (Please indicate US Citizen, Permanent Resident or Alien and Visa type/exp. date)
  • Transcripts and a copy of TOEFL results (if applicable)
    • Can be uploaded, or
    • Official copies can be mailed to Clinical Medical Physics Residency Application, One Physics Ellipse, College Park, MD 20740
  • Foreign Nationals (not U.S. Citizens or Permanent Residents) A J-1 Visa sponsorship is required for admission to the U.S. for residency/fellowship training.
    NOTE: UC Davis will not consider H-1B Visa sponsorship.

Application deadline is December 1, 2023. Position available July 1, 2024.

Applications will be accepted from individuals who are not in CAMPEP-approved graduate programs. The physics residency requires applicants to have completed all six courses of CAMPEP certification prior to starting their residency. Applicants who are in the process of attaining certification can proceed through the interview process, but all courses must be complete prior to successful acceptance into residency. Required courses are:

1. Radiological Physics and Dosimetry

2. Radiation Protection and Radiation Safety

3. Fundamentals of Imaging in Medicine

4. Radiobiology

5. Anatomy and Physiology

6. Radiation Therapy Physics

Our program participates in the Medical Physics Matching Program.

Virtual Interview Days
The radiation oncology physics residency program will use the Thalamus interview scheduling platform to host three virtual interview days. The dates are: January 25, February 8 and 22, 2024. A virtual meet and greet with our residents will be offered to available candidates the day prior to the interview.

Interview Day Information
Selected candidates can expect to receive the Thalamus email notification with invitation letter and access to the interview schedule. The interview schedule hours will be set to the Pacific Standard Time Zone (PST) and will be about 4-hours.

Thalamus will assign candidates to eight 15-minute interview sessions with a 5-minute break between interviews. Candidates will have the opportunity to interview with our six physicist, physician faculty, physics resident, chief dosimetrist, and chief therapist. The schedule will include opening/closing remarks with the program director along with a resident led program presentation with time for Q&A. Start time is subject to change based total candidates scheduled on each day.

Sample morning schedule:

9 - 9:15 a.m. Welcome and Opening Remarks
