Dr. Weichenthal is an Assistant Professor in the Department of Epidemiology, Biostatistics, and Occupational Health at McGill University in Montreal, Canada. His research program is dedicated to identifying and evaluating environmental risk factors for chronic diseases such as cancer and cardiovascular disease. To support this objective, Dr. Weichenthal develops new approaches to population-based exposure assessment and examines how the urban built environment influences environmental exposures at both the individual and population-level. His previous studies have examined the health effects of air pollution from traffic and biomass burning as well as the oxidative potential of particulate air pollution. His current research projects are evaluating the use of digital images and deep convolutional neural networks as a novel means of estimating environmental exposures.
