Josh Barocas, MD, is an Associate Professor of Medicine at the University of Colorado School of Medicine and an infectious diseases physician at Denver Health, Colorado’s largest safety-net hospital. He serves as Founding Executive Director of the Colorado Poverty and Health Initiative (COPHI), where his work focuses on generating rigorous, policy-relevant evidence to reduce health disparities driven by poverty, substance use, and structural disadvantage. His research centers on improving outcomes for people living with or at high risk for HIV and complications of drug use, including individuals with substance use disorders and those experiencing homelessness. An interdisciplinary health services researcher, Dr. Barocas uses clinical epidemiology, health economics, simulation modeling, and cost-effectiveness analysis to inform health policy and resource allocation at local, state, and national levels. His NIH R01–funded work builds on prior leadership of the Health Economics and Modeling Core of the Massachusetts HEALing Communities Study, where he led the largest community-based costing study in NIDA’s history. He developed the REDUCE microsimulation model to project long-term outcomes of injection drug use, including overdose, endocarditis, and skin and soft-tissue infections. Dr. Barocas is a Research Affiliate of the CHERISH Center and an Associate Editor of the International Journal of Drug Policy.
