Radiation Oncology


Physics Residency Program

The Department of Radiation Oncology at IU School of Medicine offers a CAMPEP-accredited Medical Physics Residency Program. One resident is accepted each year. The program provides two years of clinical training in all areas of radiation oncology physics. The resident rotates through IU Health hospitals and the Roudebush VA Medical Center.

Medical Physics residents are qualified to teach Radiation Oncology physics to medical residents, graduate medical physics students, radiation therapy students and dosimetry students. They can be a valuable asset in the didactic as well as clinical realm within radiation oncology.


Residents entering the medical physics residency program have a strong foundation in basic physics, documented by a master’s or doctoral degree in medical physics, physics, engineering, mathematics or other science with training equivalent to a minor physics. The successful candidate to this resident program holds a PhD or MS degree in medical physics, preferably compatible with CAMPEP requirements and has good written as well as oral communication skills.

Clinical training, research/publication record, and CAMPEP accreditation of the programs attended are considered in the selection of the medical physics resident. The selection of the candidate is made by a committee of at least five professionals affiliated with the program and include the director and the coordinator of the program. Other radiation oncology professionals (physicians, therapists, dosimetrists) may also be asked to serve on the selection committee.

Career Path: Medical Physicist

Medical physicists belong to a unique group of professionals who are certified by a Medical Board (The American Board of Radiology, ABR). Current requirements to sit for the ABR exam include formalized residency training in an accredited medical physics program. CAMPEP (Commission on Accreditation of Medical Physics Educational Programs) is the only entity that accredits medical physics programs and continuing education for medical physicists. Formalized medical physics residency training, accredited by CAMPEP, are required for ABR certification. Currently more than 50 percent of medical physicist are over age 50. The number of available positions are expected to increase by approximately 10 percent each year.

Clinical Facilities

Training as part of this residency program takes place in IU Health facilities, including the IU Simon Cancer Center and Methodist Hospital and at Central Indiana Cancer Center East, Central Indiana Cancer Center Fishers, Morgan County Hospital and Roudebush VA Medical Center—all in Indianapolis.


The curriculum of the Medical Physics Residency program at IU School of Medicine is consistent with AAPM report #90, Essentials and Guidelines for Hospital-Based Medical Physics Residency Training Programs.

Physician Educators

The IU School of Medicine Radiation Oncology staff includes 11 medical physics faculty, 8 medical dosimetrists, 10 MD radiation oncology faculty, 8 medical residents, and 2 PhD cancer biology faculty.

Specialized procedures include Rapid Arc therapy, Intensity modulated radiation therapy (IMRT), stereotactic radiosurgery and stereotactic body radiotherapy, high- and low-dose rate brachytherapy, total-body Irradiation, total-skin Irradiation, and Gamma Knife Perfexion treatment.
