    Biography

    I have completed my internal medicine residency training at the NYP/Weill-Cornell, New York, and fellowship in Infectious diseases/HIV at the Massachusetts General Hospital and Brigham and Women's Hospital, Harvard School of Medicine, Boston. Prior to that, I did a PhD at the Kirby Institute/University of New South Wales (Australia) in epidemiological studies in HIV/AIDS. Clinically, I'm interested in HIV primary care, cases of HIV with complex resistance history, STIs, clinical trials, and general infectious diseases. In my clinical educator role, I co-direct HIV training track of Yale Primary care internal medicine residency program. train residents and fellows at Yale in ID and HIV, as well as work with CT DPH and Sylvie Ratelle STD/HIV Prevention Training Center as the educator Faculty. My current research is focused on clinical trials in HIV and other infectious diseases as well as implementation work in HIV & STIs.
