Our group

The Environmental Epidemiology Research Group is a rapidly growing entity with links to several units at ³ÉÈËVRÊÓÆµ

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

His work takes place in North America and South Africa.Ìý He holds a doctorate in Epidemiology from the University of California, Berkeley and a Master's in Physiology-Endocrinology from Université Laval.Ìý More information on Dr. Chevrier's research may be found .

Alexandra Schmidt, PhD

Ìý

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.

Scott Weichenthal, PhD

Ìý

Ìýis 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.ÌýÌý 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.Ìý Details on his research can be found .

Program Graduates

Information about some of our graduates.

Emmanuelle Batisse, MSc

Ìý

Emmanuelle is a Master’s student in epidemiology at University of Montreal who is jointly advised by Audrey Smargiassi. She graduated with a bachelor’s degree in biological sciences and her main interests are the impacts of air pollution on public health. For her Master’s research project, Emmanuelle investigated the links between industrial emissions of PM2.5 and acute cardiovascular complications in Quebec. She now works as a Research Assistant on a project evaluating the impact of public health interventions.

Stéphane Buteau, PhD

Ìý

Stéphane obtained his PhD from Department of Medicine (Division of Experimental Medicine) and the ³ÉÈËVRÊÓÆµ School of Environment. He also olds a Master’s degree in Environmental and Occupational Health from the University of Montreal. Before starting his doctorate, Stéphane held an environmental health scientist position at the National Institute of Public Health of Quebec (INSPQ). His main research interests are in environmental epidemiology and toxicology, focusing on the impact of air pollution on human health. Stéphane investigated the acute health effects of ambient air pollution among susceptible individuals. He now works for the Institut National de Santé Publique du Québec. Outside of his research, his interests include playing ice hockey, touchfootball and doing outdoor sports.

Ellison Carter, PhD

Ìý

Ellison was a post-doctoral fellow in Energy, Air Pollution, and Health at the University of Minnesota's Institute on the Environment and is now Assistant Professor at the Colorado State University. Ellison earned her Ph.D. and M.S.E. degrees in Civil Engineering through the Environmental and Water Resources Engineering program as an NSF Interdisciplinary Graduate Research Trainee (IGERT) and EPA STAR fellow at the University of Texas at Austin.Ìý Dr. Carter is interested in developing and investigating tools to measure, characterize, and mitigate the impacts of environmental pollution on human health and the environment. Her current research efforts focus on pollution control strategies that reduce human exposure to air pollutants in indoor environments.

Sierra Clarck, MSc

Ìý

As an MSc student in Epidemiology, Sierra evaluated the health and environmental benefits of clean cooking stoves and fuels in the Sichuan, China, as well as their uptake and sustained use. Sierra recently graduated from ³ÉÈËVRÊÓÆµ with First Class Honours and Deans Honour List in the Bachelor of Arts program. Her academic background is in geography and geographic information systems, with interest in the environmental and social factors that impact disease risk in vulnerable populations. She previously worked with the Geographic Environmental Epidemiology Lab and the Indigenous Health Adaptation to Climate Change research group. She loves conducting fieldwork and using mixed-methods (quantitative and qualitative) study designs when approaching environment and health research questions.

Jonathan Huang, PhD

Ìý

Jonathan was a postdoctoral fellow in Epidemiology. He holds a BS in Biochemistry (University of Virginia), an MPH in Community-Oriented Public Health Practice and a PhD in Epidemiology (University of Washington). His interests are in the application of causal inference methods to mechanistic investigations in perinatal and life-course epidemiology as well as in the application of those methods to policy-making. He worked with Dr. Chevrier to investigate the impact of prenatal exposure to insecticides on child growth and infections in the VHEMBE birth cohort. He is now a Research Fellow in Singapore.

Thirumagal Kanagasabai, PhD

Ìý

Thirumagal is a Postdoctoral Fellow in Environmental Epidemiology at ³ÉÈËVRÊÓÆµ. She completed her PhD in Health Science at York University in Toronto. The overarching framework of her doctoral research is sleep and cardiometabolic health epidemiology of adults. Within this context, she quantified the mediating effect of dietary and physical activity factors to the relationship between sleep and cardiometabolic risk factors, estimated the associations between objective vs. subject sleep measures as they relate to cardiometabolic health, and quantified the risk of developing cardiometabolic conditions due to changes in sleep habits . She holds a HBSc and MSc in toxicology from the University of Toronto. Thiru’s Postdoctoral Fellowship focuses on environmental risk factors and their associated cardiovascular disease risks. Her research interests include sleep patterns and circadian rhythms, light and environmental exposures, biomarkers of disease and health, human activity patterns and behaviours, and cardiometabolic health outcomes.

Rachel Kohut, MPH

She then worked at The Dartmouth Center for Health Care Delivery Science on global health programs, including work in Peru, South Africa, Rwanda, Tanzania, Honduras, and with the Indian Health Service (US). She is interested in studying the effect of environmental exposures on human health, and how a better understanding of these exposures can improve health equity in Canada and around the world. At ³ÉÈËVRÊÓÆµ, Jen investigated the association between exposure to the insecticide DDT and hypertensive disorders of pregnancy among a birth cohort of mother-infant pairs in South Africa. Jen also likes to play tennis, run, ski, bike, travel, and enjoy Montreal.
