After obtaining a PhD in psychology from Laval University in 1993, Dr. Muckle completed a postdoctoral fellowship at Wayne State University (Detroit) and at the CHUL Research Center. She was first hired in 1997 as professor at the Department of Social and Preventive Medicine of Laval University, then in 2003 by the School of Psychology of the same institution. Meanwhile, she was a member of the advisory committee of the CIHR Institute of Human Development, Child, and Youth Health, and of the Chemicals Management Plan Challenge Advisory Panel, which advises the Canadian government on chemical risks. Since 2016, Dr. Muckle is Vice-Dean of Studies at the Faculty of Social Sciences at Laval University.
Dr. Muckle’s research approach encompasses epidemiology, toxicology, and developmental psychology. In addition to studying the toxicity of prenatal alcohol exposure, she pursues research on the developmental effects of exposure to environmental contaminants such as heavy metals, pesticides, and polychlorinated biphenyls (PCBs). Dr. Muckle’s work showed associations between contaminants and physical development, fine motor function, as well as with behavioral aspects, such as attention problems, and also with indicators of cognitive development.
Dr. Muckle’s interest for the adverse effects of exposure to environmental contaminants led her to work with the most highly exposed populations, among them mothers and children from Guadeloupe exposed to the pesticide chlordecone and, above all, with the Inuit population of Northern Canada, who are exposed to industrial contaminants through their traditional diet. This work allowed her to develop a strong expertise in creating and following longitudinal cohorts, which are rarely conducted in aboriginal people. Dr. Muckle’s recent work extends to determinants of health among the Inuit, notably by her collaboration with the Nunavik Inuit Health Surveys Qanuippitaa? in 2004 and Qanuilirpitaa? in 2017.
