Clinical Expertise:

Prostate Cancer, Testicular Cancer, Bladder Cancer; Intensity-Modulated and Stereotactic Radiation Therapy; Brachytherapy for Prostate Cancer

I am a board-certified radiation oncologist specializing in the treatment of prostate cancer with external beam radiotherapy (i.e. ) and Brachytherapy for Prostate Cancer (i.e. implants or seeds). I also specialize in other types of genitourinary cancers such as cancers of the testes and bladder.

I commonly use sophisticated treatment planning techniques such as IMRT (e.g. RapidArc®), and stereotactic radiotherapy (e.g. Cyberknife®). I also use various localization techniques, including gold seeds, cone-beam CT, and radiofrequency beacons (i.e. Calypso®), for prostate or prostate bed localization prior to treatment. In addition, special types of planning often are used to ensure the most precise radiation treatment available for my patients. I also perform salvage prostate brachytherapy for patients with recurrent prostate cancer after external beam radiotherapy.

I am working to develop new treatment techniques, using IMRT, that help men preserve erectile function following radiation therapy for prostate cancer. Currently, I am a co-primary investigator of this clinical trial at Fox Chase. I am a co-author of over 50 peer-reviewed scientific publications, numerous book chapters and editorials on prostate cancer, IMRT and testicular cancer.

I am dedicated to the future of radiation research. I serve as Member-at-Large of the Executive Committee of the Radiation Therapy Oncology Group (RTOG), Treasurer of the board of directors of the American Brachytherapy Society (ABS), and associate senior editor of the International Journal of Radiation Oncology, Biology, and Physics. I twice received the Roentgen Resident/Fellow Research Award from the Radiological Society of North America (RSNA) during my residency at Fox Chase. In 2005, I received ASTRO's Young Investigator Award.
