Jeffrey W. Rozelle, PhD, MPH

Biography

Jeffrey W. Rozelle is a health services and spatial epidemiology researcher whose work examines how geography, health system organization, and social conditions shape access to care. His research focuses on measuring health service environments, identifying areas of unmet need, and evaluating disparities in the availability and quality of essential health services. He combines spatial analysis, population health methods, and large administrative and survey datasets to study healthcare access in the United States and in low- and middle-income countries.

His current work focuses on health service access in the United States, including the geographic distribution of pharmacy closures, the emergence of pharmacy shortage areas, and disparities in access across racial, socioeconomic, and rural–urban contexts. He also develops public-facing data tools that translate complex spatial and policy data into accessible evidence for researchers, policymakers, and communities. His broader research has examined health facility readiness, user fees, maternal and child health services, and the relationship between service availability and patient experience across multiple countries.

Jeffrey earned his PhD in Population, Health and Place from the University of Southern California, where his dissertation examined structural and spatial dimensions of healthcare access in low- and middle-income countries. He previously served as Director of Monitoring and Evaluation at Last Mile Health in Liberia and has conducted research and evaluation work across a range of humanitarian and global health settings, including Afghanistan, Tajikistan, Kyrgyzstan, Tanzania and more. His work draws on experience in epidemiology, geographic information science, health services research, and program evaluation.
