Nicholas B Defelice, PhD

Nicholas DeFelice, PhD, is Associate Professor in the Department of Environmental Medicine at the Icahn School of Medicine at Mount Sinai and a member of the Mount Sinai Institute for Exposomic Research.

Dr. DeFelice studies environmental determinants of infectious disease transmission. He develops mathematical models that quantify disease burden attributable to poor infrastructure and other environmental exposures, along with systems to forecast infectious disease outbreaks. His current research focuses on forecasting West Nile virus outbreaks, SARS-CoV-2, Highly Pathogenic Avian Influenza, and Chagas disease. More broadly, his research addresses how climate change influences human health and environmental solutions that can promote positive health outcomes.

Dr. DeFelice holds a PhD in Environmental Science and Engineering from the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill where he also completed his Master of Science in Environmental Engineering. Prior to joining Mount Sinai, his postdoctoral training was completed at Columbia University with a focus on climate and health.
