I am an assistant professor in the School of Occupational and Public Health at Ryerson University.

I obtained a bachelor of applied science in Public Health and Safety from Ryerson University in 2007 and a PhD in Epidemiology from the University of Guelph in 2010. From 2011 to 2013, I completed a postdoctoral fellowship with the University of Guelph and the Laboratory for Foodborne Zoonoses (now part of the National Microbiology Laboratory) at the Public Health Agency of Canada (PHAC).

I later worked as an epidemiologist with PHAC and in 2015, I worked as a food safety expert with the Food Safety and Quality Unit of the Food and Agriculture Organization of the United Nations in Rome, Italy.

My research focuses on addressing applied and policy-relevant issues at the interface of human, animal, agri-food and environmental health. My research interests include food safety (from “farm-to-table”); drinking and recreational water quality; the surveillance, prevention and control of foodborne, waterborne and zoonotic diseases; and emerging threats such as climate change and antimicrobial resistance.

My expertise and research interests lie in various methodological approaches applied to these issues, including knowledge synthesis (e.g. systematic reviews and meta-analysis), knowledge transfer and exchange, mixed-method research, epidemiology and evidence-informed decision-making.

My recent research projects have included identifying the impacts of climate change on food and water safety in Canada, evaluating the determinants of and interventions to improve consumer safe food handling, and evaluating the efficacy of interventions to control salmonella in the production and processing of beef and pork.

Research Interests:
