Andrew DeWan

Andrew DeWan is an Associate Professor of Epidemiology (Chronic Diseases) at the Yale School of Public Health, serving as Co-Director of the Yale Center for Perinatal, Pediatric and Environmental Epidemiology and Director of Graduate Studies. He holds a PhD in Statistical Genetics (Rockefeller University), an MPH in Epidemiology (University of Minnesota), and a BS in Biology (Brandeis University). His research focuses on genetic epidemiology, particularly identifying genetic susceptibility variants for complex traits like asthma, obesity, leukemia, preeclampsia, and bacterial infections. He employs strategies to reduce phenotypic heterogeneity, such as ancestry-based stratification and genetic interaction analysis. His work includes large-scale GWAS and exome sequencing studies, with a focus on pleiotropy and rare variant mapping.

• Research Highlights
• Identified genetic variants linked to age-related macular degeneration, asthma, and leukemia.
• Developed methods for analyzing gene-gene interactions and pleiotropy in complex traits.
• Principal Investigator of multiple NIH grants, including three R01 awards.
• Teaches courses like Genetic Concepts in Public Health and collaborates internationally on genetic epidemiology projects.

His research emphasizes leveraging genomic data to improve understanding of disease mechanisms, with applications in personalized medicine and public health. He has published extensively in top journals and serves on committees such as the American Society of Human Genetics Program Committee.
