Meet our people

Our group

The Environmental Epidemiology Research Group is a rapidly growing entity with links to several units at McGill

Some of our focus areas include experimental medicine, pharmacology/toxicology, oncology, as well as agricultural and environmental sciences.  The core group is formed by five professors with vast and complementary expertise on environmental questions both at home and globally.


Jill Baumgartner, PhD


Dr. Baumgartner is an Associate Professor of Epidemiology and an Associate Member of the McGill School of Environment.  She investigates the impact of air pollution on chronic diseases such as cardiovascular disease in North America and in the Tibetan Plateau, China.  She holds a joint PhD in Population Health Sciences and Environment & Resources from the University of Wisconsin-Madison and a Masters in Population and International Health from Harvard University. Details of Dr. Baumgartner's work may be found here.

Jonathan Chevrier, PhD


Dr. Chevrier is an Associate Professor of Epidemiology, Canada Research Chair in Global Environmental Health and Epidemiology, and Associate Member of the McGill School of Environment and of the McGill Institute for Health and Social Policy. He studies the impact of common environmental exposures such as pesticides, flame retardants (PBDEs), plastic components (bisphenol A), and industrial by-products (dioxins, metalworking fluids) on child health and development. His work takes place in North America and South Africa.  He holds a doctorate in Epidemiology from the University of California, Berkeley and a Master's in Physiology-Endocrinology from Université Laval.  More information on Dr. Chevrier's research may be found here.

Mark Goldberg, PhD

Alexandra Schmidt, PhD


Dr. Schmidt is a Full Professor in the Department of Epidemiology, Biostatistics and Occupational Health. She is a Bayesian statistician doing research on spatial and spatiotemporal modeling of environmental, ecological and epidemiological problems. A key focus of her current research programme is to develop models for uni- and multivariate spatiotemporal processes that do not require transformation of the data, but rather can be applied to the data on their original scale. Find out more about her research here.

Scott Weichenthal, PhD


Dr. Weichenthal is an Assistant Professor in the Department of Epidemiology, Biostatistics and Occupational Health. He is an environmental epidemiologist working primarily on the chronic health effects of air pollution, indoor air quality and traffic-related health impacts.   In particular, he has recently been conducting studies on the health impacts of ultrafine particles. A notable feature of his work is the potential for a direct/practical application of study results for knowledge transfer and the development of risk management recommendations, of importance for all Canadians.  Details on his research can be found here.
