Greg Rosen
Biography
Dr. Greg Rosen is an Assistant Professor of Medicine and Epidemiology (Research) at Brown University and a Research Scientist in the Division of General Internal Medicine at Rhode Island Hospital. Dr. Rosen leads and contributes to implementation science (IS) research at the intersection of HIV treatment/prevention and substance use services, with attention to sub-Saharan Africa and the United States. His research broadly harnesses health workforce capacity-enhancement strategies and health system reconfigurations to optimize delivery of HIV and harm reduction services to marginalized populations, specifically people who sell sex and/or use drugs. Currently, Dr. Rosen serves as Principal Investigator of three IS-focused studies evaluating community-based models for HIV treatment delivery in Uganda, bathroom-based reverse-motion detectors for overdose detection and response in Boston housing facilities, and urine drug screening and post-test counseling for substance use service linkage among female sex workers living with HIV in South Africa. His areas of methodological expertise in implementation science include human-centered design, stated-preference methods (i.e., discrete choice experiments, best-worst scaling), framework-guided qualitative methods (including rapid qualitative analysis), latent variable modeling, and process/mechanism mapping.
