I am a board-certified physician who specializes in the treatment of infections in patients whose immune systems are weakened due to cancer, cancer therapy, or infection with HIV. I’m also interested in educating trainees, allied healthcare professionals, and physicians about appropriate antibiotic selection and use through my work with Memorial Sloan Kettering’s Antibiotic Management Program (AMP). 


The discovery of antibiotics in the early 20th century transformed medicine by giving us the tool to treat once-deadly infections. However, antibiotic-resistant bacteria are a growing problem, and improving how we prescribe antibiotics is important. As the founding Director of AMP, I work with two full-time clinical pharmacists and a data manager to optimize antibiotic use within MSK. The AMP team provides advice to prescribers on optimal selection, dose, and duration of antimicrobial therapy; educates healthcare professionals on rational antimicrobial use; and monitors antibiotic usage patterns to identify areas for improvement. We also develop and update evidence-based antimicrobial guidelines, which are an important resource for prescribers. Finally, the AMP works closely with other services and departments within MSK, such as infection control, clinical laboratory, pharmacy, information services, and various medical and surgical oncology services.  

My clinical research interests are related to antimicrobial stewardship and include examining stewardship methods to optimize antimicrobial use, the relationship between antimicrobial exposure and outcomes, and the interplay between microbiological testing and antimicrobial prescribing.


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.
