Assistant Professor of Medicine (Research)

Overview

Dr. Joseph "Greg" Rosen (he/him/his) 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. Greg leads and contributes to implementation science research at the intersection of HIV treatment/prevention and substance use services globally. 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 mobile and displaced populations (i.e., sex workers, people who use drugs, justice-involved persons) in sub-Saharan Africa and the United States.

Currently, Greg serves as Principal Investigator of three implementation science-focused studies evaluating community-based models for HIV treatment delivery in Uganda (funded by the Johns Hopkins University Center for AIDS Research), bathroom-based reverse-motion detectors for overdose detection and response in Boston housing facilities (funded by Bloomberg Philanthropies), and urine drug screening and post-test counseling for substance use service linkage among female sex workers living with HIV in South Africa (funded by the Providence/Boston Center for AIDS Research). His areas of methodological expertise include human-centered design, stated-preference methods (i.e., discrete choice experiments, best-worst scaling), qualitative and mixed-methods research (including rapid qualitative analysis), latent variable modeling, and process/mechanism mapping. 

Greg earned his Master's of Science in Public Health (MSPH) and Doctorate of Philosophy (PhD) in Social and Behavioral Interventions from the Department of International Health at Johns Hopkins University Bloomberg School of Public Health. Prior to his appointment at Brown University, Greg held positions at the Centers for Disease Control and Prevention (CDC), the U.S. Agency for International Development (USAID), and Population Council. He has contributed to public health research and practice in over 20 countries and has consulted for several non-governmental and multilateral organizations, including Médecins Sans Frontières, the United Nations Children's Fund (UNICEF), and the Elizabeth Glaser Pediatric AIDS Foundation. 

Greg is affiliated with the Implementation Science/HIV Scientific Working Group of the Providence/Boston Center for AIDS Research and the Brown Research on Implementation and Dissemination to Guide Evidence Use (BRIDGE) Program, through which he provides consultative services on implementation science study designs and methodology. His scholarship has been published in high-impact peer-reviewed journals including Addiction, Clinical Infectious Diseases, Journal of the International AIDS Society, and Social Science & Medicine.
