Planet Earth is in a swirl of data.

Our faculty have backgrounds with experience including:

  • employing diverse methodologies spanning economics, epidemiology, public policy, psychology, and implementation science
  • serving as a methodological expert on studies investigating pathways through which structural racism influences diabetes outcomes
  • supporting health systems improvement with a primary focus on primary care integration and leveraging community organizations to improve chronic disease outcomes
  • designing, implementing, and analyzing clinical trials, as well as applying survey methods to observational data
  • clinical trials methodology, qualitative and mixed methods study designs, large database observational study methodology, community based participatory research and implementation science

Impactful Research Efforts

Members of our division are currently conducting research in areas including:

  • intervention development for type 2 diabetes that incorporates behavioral economics principles, including cash transfers
  • developing and testing interventions delivered in community-based settings that address social and structural factors impacting adults with cardiovascular disease
  • examining strategies and implementation outcomes of HIV pre-exposure prophylaxis (PrEP) delivery in high-incidence populations, with an ongoing project in Nigeria aimed at exploring the potential of private community pharmacies as an avenue to improve accessibility
  • addressing population health, optimizing health outcomes for vulnerable populations and investigating disparities in health care costs
