Internal Medicine; Infectious Disease

I am an internist and infectious disease specialist with a special interest in the care of patients with infections related to cancer or its treatment. I am particularly interested in treating mycobacterial infections among immunocompromised patients, including infections with nontuberculous mycobacteria.

The focus of my laboratory research is the use of Bacillus Calmette-Guerin (BCG), a bacterium normally used as a vaccine against tuberculosis, as an immunotherapy for bladder cancer. The aim of my research is to understand the mechanism of action of BCG, with the long-term goal of translating this understanding into improved care for patients with early-stage bladder cancer.

In the past several years, the field of cancer immunotherapy has expanded far beyond BCG therapy for bladder cancer. These exciting new therapies are associated with robust response rates, but the full extent of side effects associated with these agents is yet unknown. My fascination with BCG immunotherapy of bladder cancer has also led to an interest in these novel methods of immunotherapy, and I have embarked on a study of infections among patients receiving various forms of cancer immunotherapy.
