Research Interests:

  • GIS & spatial methods
  • Access to health care
  • Health disparities
  • Environmental exposure
  • Mobile health



I am interested in using GIS and spatial methods to understand and solve environment/health problems. My current research covers four major topics: mobile health, environmental exposure, access to healthcare, and health disparities. More information of my research could be found at the website of the Utah Geo-Health Lab.
