Dr. Mary Ann Chiasson's research focuses on the epidemiology of HIV, particularly risk factors for sexual transmission; women's reproductive health; and early childhood obesity.

She has co-directed the HIV/AIDS Epidemiology course at the Mailman School since 1989. Dr. Chiasson served in various capacities at the New York City Department of Health from 1986 through 1999, including nine years as an assistant commissioner of health with scientific and administrative responsibility for AIDS Surveillance, HIV/AIDS Research, and Vital Statistics and Epidemiology.
