About Me

I am a board-certified dermatologist specializing in the diagnosis and treatment of cancers of the skin. I am the director of Memorial Sloan Kettering’s regional skin cancer clinic in Hauppauge, Long Island. In addition to consulting and treating patients in Hauppauge, I also see patients at the Center’s outpatient facility in Manhattan.

Although providing the best care possible for my patients remains my primary goal, I also remain committed to education and clinical research. My hope is that educating physicians and the public about the importance of early skin cancer detection will help save lives.

I am active in clinical research and have published numerous papers on topics related to skin cancer with an emphasis on melanoma, atypical/dysplastic nevi, and congenital melanocytic nevi. My research interests are focused on the use of imaging instruments such as photography, dermoscopy, and confocal laser microscopy to recognize skin cancer early in its development. I frequently lecture on these topics both nationally and internationally.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
