Internal Medicine

I am an internist with an expertise in treating infectious diseases. I am an attending physician in Memorial Sloan Kettering’s Urgent Care Center, where we specialize in the care of the medical emergencies that result from cancer and its treatment. We have just written several chapters for a new textbook on emergency oncology that will be published this year.


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
