Howard  Chang

Associate 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) 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, and disease surveilleince systems. I also have collaborative experience in ecology, infectious disease, social epidemiology, and community intervention trials.

Current Projects:

1. Data Integration Methods for Environmental Exposures with Applications to Air Pollution and Asthma Morbidity.

2. Spatio-temporal Data Integration Methods for Infectious Disease Surveillance.

3. Extreme Heat Events and Pregnancy Duration: a National Study
