James Quinn is a Geographer and Senior Geographic Information Systems (GIS) Analyst based at the Department of Epidemiology at Columbia University. He received both his BA and MA in Geography from the University of Northern Iowa. Quinn conducts medical geography research and works on numerous grant-funded research projects where he is responsible for the acquisition, management, development, and linkage of retrospective and modern spatial databases measuring neighborhood characteristics with individual-level data. Using non-routine spatial modeling techniques, Quinn, makes connections between the changes in the physical, economic, and social environments, and evaluates their affect on the development of changes in physical activity, patterns of obesity, and health risk. Quinn also supports other researchers with health-related projects involving a spatial perspective, and collaborates with other colleagues to enhance and promote the use of spatial analysis in teaching and research at Columbia.
