Lauren Grant is an Assistant Professor of Environmental and Public Health and epidemiologist in the Department of Population Medicine at the University of Guelph.

Research Interests

My research program investigates the social and environmental determinants of One Health in animal and human populations using both quantitative and qualitative approaches. I am especially interested in using novel, linked data to understand how these determinants impact health and health inequalities. My program has three areas of focus: 1) Social and environmental determinants of population health and health system utilization, 2) Health inequities in population health outcomes, and 3) Social and environmental determinants of companion animal health and veterinary care utilization. I am also keen to collaborate on projects investigating social and environmental determinants where my knowledge and skills can be an asset.


I am currently recruiting graduate students for the following positions, beginning in Fall 2022:

  • Thesis-based MSc students (three funded positions available, domestic or permanent residents only) to evaluate public communications during multi-jurisdictional enteric outbreak investigations in collaboration with and funded by the Public Health Agency of Canada. Please click on the following links to learn more about these positions: Position 1, Position 2, and Position 3.
  • PhD student (one funded position available, domestic or permanent residents only) to investigate climate-sensitive food safety risks and their mitigation strategies. This position is funded by the Department of Population Medicine, Public Health Agency of Canada, and the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), through the Ontario Agri-Food Innovation Alliance.

  • PhD student(s) (domestic or permanent residents only) who are interested in either a) avoidable hospital use in human or veterinary populations, b) pet ownership as a social determinant of health or c) socioeconomic status and veterinary care utilization. Prospective students will need to apply for and receive a scholarship to support their stipend. 
  • Prospective MSc and PhD students should contact me by June 24, 2022 using the following form to tell me more about yourself and your interests. Students from underrepresented groups are strongly encouraged to apply.
