Howard Chang
Professor
Faculty, Biostatistics and Bioinformatics
Jointly Appointed, Environmental Health
My 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) health effect estimation and impact assessment leveraging large databases, such as birth/death certificates, hospital billing records, electronic health records, and disease surveilleince systems, and (2) exposure assessment for air quality and extreme weather events, especially under a changing climate.
I am a PI of the ENVISON (Environmental Exposures and Health Across the Nation) Research Group and the Data Core co-lead for the CARRS (Cardiometabolic Risk Reduction in South Asia) Cohort. I am also a member of the HERCULES Exposome Research Center and the Emory Climate & Health Actionalbe Research and Translation Center (CHART).
