I am a physician who cares for people with prostate cancer, kidney cancer, and bladder cancer. I care for people along different points of their cancer journey. I see people who are newly diagnosed as well as those seeking second opinions. I also see people whose cancer is no longer curable but often have options that can help them manage it, like a chronic disease.

I do my best to address patients’ concerns and discuss the pros and cons of each care option. These can range from available treatments and clinical trials to pain control, nutrition, and hospice. I aim to help people choose the most effective care plan for their particular disease and treatment goals.

It is gratifying when patients and caregivers tell me they have learned a lot from their visit with me. My hope is that they feel comfortable asking questions. I want them to leave with a better understanding about their treatment options, possible side effects, and how to manage the impact of treatment on their quality of life.

I am also the Chief of the Imaging and Spectroscopic Physics Service in the Department of Medical Physics. In addition to seeing patients, I perform laboratory research focused on developing new therapeutic targets and enhancing the interaction of radiation and chemotherapy to improve treatment outcomes.

Currently, I am conducting preclinical studies to block breast and prostate tumor growth. This process inhibits several key steps required to generate energy and important biomolecules. I have published the results of my work in various scientific journals.

I earned my medical and doctorate degrees from the State University of New York, where I participated in one of the original groups that developed magnetic resonance imaging (MRI) in the 1970s. After completing my training in Boston, I joined MSK in 1985 to develop a program in biological magnetic resonance. This is an imaging technique to study tumor metabolism and microenvironments.

I am an active member of the International Society for Magnetic Resonance in Medicine and the American Society of Clinical Oncology.

Outside of work, my life is devoted to my wife, children, and grandchildren. I am also a history buff and have had interesting historical discussions with some of my patients.
