Department of Epidemiology and Health Services Research

The Department of Epidemiology and Health Services Research offers unique opportunities for epidemiologic, outcomes, health services, social and behavioral health and population health, including community-based research. The department’s mission is to discover the means of understanding health and healthcare. This department conducts research to address health and healthcare delivery across patients, providers, the health plan and the population.

Core areas of focus include:

  • The science of healthcare delivery, seeking solutions to simultaneously improve the quality and efficiency of healthcare;
  • Comparative effectiveness research (CER), emphasizing health economics and the application of novel methods that improve the validity of findings;
  • Epidemiology;
  • Social and behavioral health research, characterizing behavioral conditions and co-occurring illness influenced by social and behavioral issues and addressing the most challenging barrier to improving outcomes - patient’s health needs and care delivery models that improve access and outcomes;
  • Population and community health, including research on rural communities;
  • Environmental health, focusing on how the local environment influences health.
