Our Board of Directors

Meg Sears (Chair)

Margaret (Meg) Sears was trained in Chemical Engineering and Applied Chemistry at the University of Toronto, Canada. She worked in energy research, then returned to academia to complete doctoral research in biochemical engineering at McGill University. With skills in scientific analysis and writing, Dr. Sears gained associations with Ottawa research institutes at the Children’s Hospital of Eastern Ontario Research Institute, and the Ottawa Hospital Research Institute. Some highlights for Dr. Sears include: writing the Medical Perspective on Environmental Sensitivities for the Canadian Human Rights Commission, leading to a policy under the Canadian Human Rights Act; carrying out a scoping review on toxic elements (arsenic, cadmium, lead and mercury) with Canadian Institutes for Health Research and Social Sciences and Humanities Research Council funding; and numerous collaborations with members of the Environmental Health Committee of the Ontario College of Family Physicians. A central interest is the conduct and interpretation of science in environmental health. When she is not working, you’ll probably find Meg roaming the outdoors, or “playing in the mud,” gardening.

Ellen SweeneyEllen Sweeney

Ellen Sweeney is a health researcher and policy analyst who is interested in environmental health, women’s health, and primary prevention of disease. She completed a PhD in the Faculty of Environmental Studies at York University and an MA in Social Anthropology at Dalhousie University. Her doctoral research analyzed the laws, policies and practices that encompass Canada’s regulatory regime for toxic substances in order to determine if they are inherently precautionary, and if they enact a primary prevention approach. This research identified the gaps in law, policy and practice and in doing so, concludes that women’s health is not adequately protected from detrimental health outcomes, including breast cancer. Ellen currently works as a Research Scientist at the Atlantic Partnership for Tomorrow Project (Atlantic PATH) in Halifax, Nova Scotia. She has also worked with the National Network on Environments and Women’s Health, Canadian Women’s Health Network, Nova Scotia Health Research Foundation, Dalhousie University, and on CIHR team grants on environmental contaminants and reproductive health.
