Lauren Grant

Assistant Professor   |   MSc, PhD


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 not actively recruiting graduate students at this time. My next available positions are:

  • One thesis-based MSc position, beginning in May 2023. More information will be posted and recruitment for this position will begin in December 2022.
  • One Master of Public Health practicum student, beginning in May 2023. Information will be posted by the University of Guelph MPH Program.
  • Prospective students can always contact me using the following form to tell me more about yourself and your interests. Your application will be kept on file and reviewed when a position is available. Students from underrepresented groups are strongly encouraged to apply. Interested students should check back often as new positions will be posted as funding is secured.

Graduate students interested in completing POPM*6600 Public Health Research, undergraduate students seeking a fourth-year thesis supervisor, and students seeking volunteer research experience are welcome to contact me at any time using the above form.
