I am a board-certified radiation oncologist specializing in the treatment of skin and eye cancers with radiation therapy. I work closely with other cancer specialists at Memorial Sloan Kettering to coordinate and deliver the best possible care for our patients.
In addition to taking care of patients, I study ways to make radiation therapy more effective, while reducing the side effects of treatment. To do this, I perform experimental laboratory research on the biologic response to radiation. I also work with members of the Medical Physics department to create new ways of giving radiation therapy.
I am chairman of an international research study through the Center for International Bone & Marrow Transplant Research. My research has been supported by the American Society for Radiation Oncology (ASTRO), the Lymphoma Foundation, and the National Institutes of Health. I have authored several chapters in major radiation oncology textbooks as well as several peer-reviewed research studies in journals such as the New England Journal of Medicine, Journal of the National Cancer Institute, Clinical Cancer Research, Radiation Research, and the International Journal of Radiation Oncology, Biology and Physics.
In addition, I teach students and other physicians about radiation oncology, and am vice chairman of the ASTRO Radiation and Cancer Biology Teaching and Curriculum Subcommittee.
