Dustin T. Duncan, ScD, is an Associate Professor in the Department of Population Health at the New York University School of Medicine, where he directs the NYU Spatial Epidemiology Lab. As a social and spatial epidemiologist, he studies how specific neighborhood characteristics influence population health and health disparities. His work includes applying emerging geospatial technologies such as Global Positioning System (GPS) devices and smart phones to, in part, examine mobility and social networks in neighborhoods. Dr. Duncan completed his doctorate and the Alonzo Smythe Yerby Postdoctoral Fellowship, both in social epidemiology, at the Harvard University T.H. Chan School of Public Health.
