Paul Villeneuve is an Associate Professor in the Department of Health Sciences. An epidemiologist by training, he has a primary program of research assessing the link between environmental and occupational exposures on the health of Canadians. He is currently involved in several large scale cohort studies that are investigating associations between long-term exposure to outdoor air pollution and the risk of cardiovascular disease, hypertension and diabetes. He also serves on an expert advisory group looking at the health impacts from the operation of wind turbines, and collaborates on miners’ studies that estimate cancer risk from radon exposure. More recently, his research program on air pollution has been expanded to include its role on oxidative stress mechanisms related to dementia and neurodegenerative disease. He is also involved in multiple Canadian and international studies that aim to improve our understanding of the health benefits associated with increased access to urban green space. These benefits include reductions in obesity, sedentary behavior, and the incidence of chronic disease.
