Internal Medicine

As a hospitalist, I care for critically ill people who are admitted to Memorial Sloan Kettering Cancer Center (MSK) for a variety of medical conditions. I primarily diagnose and care for people with infections such as pneumonia and urinary tract infections, as well as cardiac conditions, kidney conditions, gastrointestinal conditions, pulmonary disease, and other illnesses.

I am also interested in the physician-patient interaction, especially as it relates to end-of-life care and how best to tailor a patient’s treatment plan using their individual goals of care.

In my free time, I enjoy being active (running, working out), traveling, reading — mostly New York Times articles — and always looking for the best pizza slice the city has to offer.
