Julia Marcus

Julia Marcus, PhD, MPH is an infectious disease epidemiologist and Assistant Professor in the Department of Population Medicine at Harvard Medical School and Harvard Pilgrim Health Care Institute, and Adjunct Faculty at The Fenway Institute. Her research focuses on HIV, hepatitis C, and other sexually transmitted infections, with a primary interest in the implementation of HIV preexposure prophylaxis (PrEP) to improve sexual health. Her studies have leveraged data from electronic health records to identify patients who may benefit from PrEP, characterize PrEP uptake and continuation, and document clinical outcomes among PrEP users in real-world healthcare settings.

Dr. Marcus received her doctoral degree in epidemiology from the University of California, Berkeley, and completed a postdoctoral fellowship at the Kaiser Permanente Division of Research.
