Biography
Jeffrey Wickersham is an Associate Professor of Medicine in the section of infectious diseases and Director of the mHealth Research & Innovation Lab (mHRI) at YSM. His research is focused on improving HIV treatment and prevention outcomes among sexual and gender minorities, including transgender women, gay men, and bisexual men. Dr. Wickersham's research has focused on development of biomedical and behavioral interventions, including peer/patient navigation, implementation of pre-exposure prophylaxis (PrEP) for HIV prevention, development of artificial intelligence-based "chatbot" technology to improve uptake of HIV testing, and adaptation of mHealth applications for transgender women to scale-up HIV testing and linkage to PrEP services. Most of this research is being conducted in Southeast Asia, primarily at sites in Malaysia and Thailand.
