Get to Know Me

I am a diagnostic radiologist and nuclear medicine physician with fellowship training in body imaging. My role in the care of patients at Memorial Sloan Kettering involves interpretation of positron emission tomography (PET), computed tomography (CT), ultrasound, and general molecular imaging. I aid in the diagnosis, staging, and follow-up evaluation of patients during treatment.

I am also involved in teaching, multidisciplinary research, and multidisciplinary conferences. I am an active member of several professional organizations including American College of Radiology, American Roentgen Ray Society, Radiological Society of North America, and Society of Nuclear Medicine. I currently participate in several clinical trials evaluating treatment approaches for breast, prostate, gynecologic cancers, and lymphomas.

I am involved in the expansion of Memorial Sloan Kettering’s services to our Long Island patients at our regional facility in Commack, New York.  Since we started providing PET/CT services at Commack in spring 2011, I have participated in performing and interpreting PET/CT exams for our patients at that facility. I am also involved in CT and ultrasound at our Manhattan and Commack sites and provide ultrasound-guided thyroid biopsies at the main campus in Manhattan.
