Howard  Chang

Professor

Faculty, Biostatistics and Bioinformatics

Secondary Appointment, Environmental Health

My primary research interest is in the development and application of statistical methods for analyzing complex spatial-temporal exposure and health data. I also conduct original epidemologic investigations on health effects of environmental exposures, including air pollution, heat, and the built environment. Our current projects fall under two broad themes: (1) health effect estimation and impact assessment leveraging large databases, such as birth/death certificates, hospital discharge records, electronic health records, and disease surveillance 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).
