Dr. De Silva is currently on a leave of absence serving as a AAAS Science and Technology Policy Fellow.

Gretchen De Silva, Ph.D., M.P.H. is a lecturer and advisor for the Public Health Science program. She has an additional appointment as assistant clinical professor in the Department of Epidemiology and Biostatistics. Her research interests include the epidemiology of infectious diseases and monitoring and evaluation of infectious disease programs, policies, and interventions. Her teaching philosophy is focused on the use of active learning and facilitating an environment that is accessible to all races, genders, and learning preferences.

Dr. De Silva received her Ph.D. in virology from the Johns Hopkins University as part of a joint program with the National Institutes of Health, where she conducted her research. She focused on examining the molecular mechanisms of cell entry for the vaccinia virus and developing immunologic tools for blocking that entry. For her postdoctoral work she completed an M.P.H. in infectious disease epidemiology at Columbia’s Mailman School of Public Health and worked closely with the International Center for AIDS Care and Treatments Programs in Kenya. Her research focused on reasons why patients with HIV drop out of treatment and analysis of a program for tracing such patients.

In spring of 2016 Dr. De Silva initiated the founding of the College Park chapter of Students Engaged in Public Health (SEIPH). SEIPH is a Public Health Science student group, which is focused on creating a space for student networking as well as serving the local community.
