Board Certifications

Internal Medicine; Infectious Disease

My clinical interests include the management of infectious complications from cancer and its treatment. I have extensive experience treating fever/neutropenia, lymphedema-related cellulitis, recurrent Clostridium difficile infection, surgical infections and abscesses, bone/joint infections, and hardware and recurrent urinary tract infections, among other conditions. 

My research interests include infections in the immunocompromised host, recurrent C. difficile infection and fecal transplants in cancer patients, and the effect of pneumonia vaccination on the epidemiology of Streptococcus pneumoniae infections at Memorial Sloan Kettering. 

I am also actively involved in administration and the medical education of students, interns, and infectious disease fellows at MSK and Weill Cornell Medical College. 


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.
