Donna Mergler is a Professor Emerita in the Department of Biological Sciences Faculty at the Université du Québec à Montréal (UQAM) and a member of the research group CINBIOSE (Centre de recherche interdisciplinaire sur le bien-être, la santé, la société et l’environnement), a World Health Organisation and Pan-American Health Organisation Collaborating Centre for the Prevention of Occupational and Environmental Illness. She is a neurophysiologist, whose research focuses on early neurotoxic effects of exposure to environmental and workplace pollutants. She is best known for her work on methyl mercury neurotoxicity in fish-eating populations and neurotoxic effects of exposure to airborne and waterborne manganese throughout the lifespan. She has contributed to the development of an ecosystem approach to human health, which draws upon interdisciplinary expertise from the natural, social and health sciences and participatory methodologies, with a view to promoting gender and social equity and to bring about concrete and lasting solutions to health problems resulting from poor working conditions and environmental degradation. She heads the Canadian Institutes for Health Research (CIHR) Emerging Team on Gender, Environment and Health. This Pan-Canadian team is developing quantitative and qualitative methods to better integrate sex and gender considerations into environmental and occupational health research.
