Dr. Mariam El-Zein is an Epidemiologist and Associate Director for Research in the Division of Cancer Epidemiology at McGill University. Formerly, she was a Research Associate at the INRS-Institut Armand-Frappier (2011-2014), at Centre Hospitalier de l’Université de Montréal (CHUM) (2007), and Sainte-Justine Hospital (2003-2005) research units, as well as a Consultant Epidemiologist at the Department of Chest Medicine, Sacré-Cœur Hospital (2007-2008).

Dr. El-Zein obtained a bachelor’s degree (B.Sc.) in Environmental Health (1993), and a M.Sc. in Public Health (1995) from the American University of Beirut, Lebanon. In 2003, she earned a Ph.D. in Occupational Health from McGill University in the joint departments of Epidemiology, Biostatistics and Occupational Health. As part of her postdoctoral training at the INRS-Institut Armand-Frappier, University du Quebec (2007-2011), Dr. El-Zein contributed to the design and implementation of studies investigating the link between immune stimulation at an early age and the development of inflammatory and autoimmune diseases such as childhood asthma and type 1 diabetes using administrative socio-demographic and medical databases in Québec. She also developed an expertise in conducting systematic reviews and meta-analyses. Other research interests include occupational health and exposure assessment as well as cancer etiology (lifestyle and environmental exposures). Her current interests are in cancer epidemiology and clinical trials with a special focus on HPV infections and prevention of cervical cancer. Another focus of Dr. El-Zein research includes methylation biomarker discovery and validation as well as the vaginal microbiome in relation to HPV infections and cervical carcinogenesis.

Dr. El-Zein is a Core Group member in the COVID-19 and Cancer Program (previously, the McGill Task Force on the Impact of COVID-19 on Cancer Control and Care), whose goal is to assess the impact of the pandemic on various aspects of services and activities related to cancer screening and care and prepare a contingency plan to mitigate future cancer risks.
