His primary research interest is in the development and application of statistical methods for analyzing complex spatial-temporal exposure and health data. Our current projects focus on two broad areas of population health: (1) exposure assessment for air quality and extreme weather events, especially under a changing climate, and (2) health effect estimation and impact assessment leveraging large databases, such as birth/death certificates, hospital billing records, electronic health records, and disease surveilleince systems. I also have collaborative experience in ecology, infectious disease, social epidemiology, and community intervention trials. Currently has NIEHS funded work on extreme heat events and pregnancy duration in the U.S.
