Dr. Hart is Scientific Director of GUTS. She is Associate Professor of Medicine at the Channing Division of Network Medicine, Department of Medicine, Brigham and Women’s Hospital and Harvard Medical School and in the Department of Environmental Health at Harvard T.H. Chan School of Public Health. Her research focuses on environmental and occupational risk factors of chronic diseases. She is particularly interested in the effects of air pollution and other environmental exposures. She is a founding member of the Spatial and Contextual Exposomics and Epidemiology Laboratory. She also leads the Reproductive Effects of Chemical and Air Pollution (RECAP) study in GUTS, which examines the impact of air pollution and daily chemical exposures on semen quality.

Peter James, ScD

Peter James is an Assistant Professor in the Department of Environmental Health. His research focuses on estimating the influence of spatial factors, including exposure to nature, the built environment, air pollution, light pollution, noise, and socioeconomic factors, on health behaviors and chronic disease. He is developing methodologies to assess real-time, high spatio-temporal-resolution objective measures of location and behavior by linking smartphone-based global positioning systems (GPS) and consumer wearable device accelerometry data to understand how spatial factors influence health behaviors.
