The Center for Community-Based Population Health Research (CCPHR) focuses on understanding community-level population health by examining the role of place, methodology, and theory in shaping health outcomes. Research areas span various fields where location plays a key role, such as sociology, health policy, and epidemiology. CCPHR takes a comparative approach to exploring how different environments influence health, health-related behaviors, access to services, and policy development. By emphasizing local contexts, this approach helps identify factors that contribute to health challenges related to substance use, mental health, homelessness, and infectious disease risk in diverse settings.
