Dr. Stephen M. Hahn, Chair and Henry K. Pancoast Professor of Radiation Oncology, will head up the new Roberts Proton Therapy Center at PENN. Hahn was appointed Chair of Radiation Oncology last year because of his reputation for excellence as a superb clinician and researcher, his highly collaborative and dynamic leadership style, and his vision for the department. Hahn is an active clinician with particular expertise in treating lung and genitourinary cancers and in the use of photodynamic therapy. As Vice Chair for Research for the Department of Radiation Oncology and Principal Investigator of National Cancer Institute grants, he led the expansion of the department’s research base, which has consistently ranked first or second in NIH funding.
Prior to joining Penn in 1996, Hahn was a Medical and Radiation Oncologist in Santa Rosa, CA. From 1993-95, he served as Chief of the National Cancer Institute’s Prostate Cancer Clinic, Clinical Pharmacology Branch, in Bethesda, MD, and a senior investigator at the NCI. Hahn also served as a Commander in the NCI’s U.S. Public Health Service from 1989-95.
After joining Penn in 1996, Hahn served as an Assistant Professor of Radiation Oncology and Hematology/Oncology until 2001, when he was appointed Associate Professor. For the past several years, Hahn has served as Director of Penn’s Photodynamic Therapy program, which treats cancer patients through a minimally invasive process that uses a photosensitizer and concurrent laser light to selectively destroy tumors. He also directs the Farnesyltransferase Inhibitor Program for Treatment of cancer of the lung, head and neck and pancreas. In addition, Hahn is the Program Leader of the Radiation Biology Research Program in the Abramson Cancer Center of the University of Pennsylvania, and is appointed to the Cancer Center’s executive committee.
Board certified in Internal Medicine, Radiation Oncology, and Hematology/Oncology, Hahn received his medical degree from Temple University School of Medicine and his undergraduate degrees from Rice University. In 1987, he completed his residency and served as Chief Resident of Internal Medicine at the University of California, San Francisco. Hahn also completed a Medical Oncology Fellowship at the NCI in 1991, and a Radiation Oncology Residency at the NCI in 1994.
Hahn currently serves as Associate Chair for the Annual Meeting and Program Committee of the American Society of Therapeutic Radiology and Oncology, and as Sub-Committee Chair for the ASTRO Annual Meeting-Scientific Program.
A long-standing member of the American Society of Clinical Oncology, Hahn is also an active member of the Radiation Research Society, the American Society of Photobiology, the American Association for Cancer Research, and the University of Pennsylvania’s John Morgan Society.
