The Graduate Programs in Medical Physics, which are offered jointly with the Department of Radiation and Cellular Oncology, offer research training at the M.Sc., Ph.D. and postdoctoral levels. Primary areas of research by program faculty include the physics of diagnostic radiology, physics of nuclear medicine and physics of radiation therapy. Unique features of this program are the faculty's focused effort on research in medical imaging and on the training of high-level medical physicists. The Department of Radiology has a training grant from the National Institutes of Health that supports four pre-doctoral students and two postdoctoral fellows. In addition, seventeen research grants from the NIH, the United States Army, the American Cancer Society and the Whitaker Foundation are available to support trainees in the Graduate Programs in Medical Physics. Currently, 25 basic scientists are involved in teaching 28 graduate students who are working toward a Ph.D. degree and 2 postdoctoral fellows. Most research projects involve collaboration between basic scientists and clinical colleagues in the department.
