Research interests

Maryse Bouchard’s research focuses on the effects of various environmental contaminants on community health. Her work aims to identify and quantify health risks through epidemiological studies, including risks to the nervous and endocrine systems. She has conducted research on the risks associated with exposure to metals like manganese and lead, as well as pesticides and other chemical products. Many of her studies focus, or have focused, on population groups with vulnerability factors like fetuses and children, seniors, Indigenous peoples, and people who work with toxic products.

Functions 

Maryse Bouchard is an associate professor of environmental health and a researcher at the Centre de recherche du Centre Hospitalier Universitaire Sainte-Justine (Sainte-Justine hospital research centre). She holds the Canada Research Chair in Environmental Contaminants and Community Health. 

She is co-principal investigator of the Maternal-Infant Research on Environmental Chemicals (MIREC) Research Platform, a body of research from a pan-Canadian study of 2,000 pregnant women and their children funded by Health Canada. 

  

Biography 

Maryse Bouchard completed a degree in biology, followed by an interdisciplinary PhD in environmental sciences, at the Université du Québec à Montréal (graduated in 2007). She then completed three years of training in environmental epidemiology at the Harvard School of Public Health and UC Berkeley (2007–2010). After returning to Montreal, she joined the Université de Montréal’s department of environmental and occupational health as a professor (2010–2022). Since 2019, she has held the Canada Research Chair (Tier 2, CIHR) in Environmental Contaminants and Community Health. 

Professor Bouchard has published more than 65 original articles in scientific journals and her work has had a strong impact on both public awareness and policy-makers. Her research program in environmental epidemiology is primarily funded by various granting agencies including the Canadian Institutes of Health Research (CIHR), the Fonds de recherche du Québec – Santé (FRQS), Health Canada, the French Agence nationale de la recherche, and the Sick Kids Foundation. 

She sits on several grant and scholarship committees in Canada, France, and elsewhere in the world. She earned the honour of becoming a visiting professor at the Université Paris Cité (Sorbonne Université network) in 2016 and 2019. Finally, she has been invited to serve as scientific advisor for a major research program funded by the European Union and present her work in Amsterdam, Tokyo, and Paris. 

Her work has received several awards: Governor General’s Academic Gold Medal (best doctoral thesis, 2007), Paper of the Year from the journal Environmental Health Perspectives for the most cited article in 2012 (Bouchard MF et al., Prenatal exposure to organophosphate pesticides and IQ in 7-year-old children), and Top 10 Discoveries of the Year by Québec Sciences magazine in 2010 (paper on manganese exposure in drinking water and cognitive deficits in children in Quebec) and 2011 (study on prenatal exposure to pesticides and IQ in children in California).
