Professor in Radiology

James T. Dobbins III, PhD., FAAPM
Associate Vice Provost
Director, Office of Duke Kunshan University Programs
Professor of Radiology, Biomedical Engineering, and Physics
Chair, Education Council, American Association of Physicists in Medicine
Co-founder, Society of Directors of Academic Medical Physics Programs, Inc.

I serve in senior university administration as Associate Vice Provost for DKU Programs. In this role I oversee the academic and programmatic efforts at Duke for the establishment of the graduate and undergraduate programs at Duke Kunshan University -- Duke's joint venture university in Kunshan, China.

My research career has focused on the application of physics to medicine. I undertake projects that range from theoretical/mathematical projects, to invention of new imaging devices, to clinical trials and implementation of new imaging modalities. Several research projects in my lab have resulted in commercial products that are now in use in hundreds of hospitals around the world.

I also have a passion for leadership and education. I was the founding Director of the Medical Physics Graduate Program at Duke, which includes over 50 faculty and 50 MS and PhD students in diagnostic imaging physics, radiation oncology physics, nuclear medicine physics, and medical health physics. I co-founded the Society of Directors of Academic Medical Physics Programs, Inc, which works to strengthen medical physics education worldwide. And I currently serve as Chair of the Education Council for the American Association of Physics in Medicine, and through this work influence major educational directions for our field.

Whether in biomedical research, education, or university leadership, the goal of my career has been to enhance the common good in our globally connected community.
