Research interests

My research aims to prevent foodborne and related diseases in Canadian and international contexts, and to enhance public health practice both broadly and within environmental health.

To this end, I investigate the burden and risks for these illnesses, and identify and evaluate interventions (including those currently in use, like food handler training). My research applies a systems lens to food-related health outcomes: food and its consumption is a confluence of risks and benefits which impact infectious diseases, chronic conditions, and nutrition, and I explore food safety strategies that account for the multiple health outcomes associated with the production and consumption of food.

My research involves tools that improve the use of evidence in public health decision making, particularly those that allow multiple or competing perspectives. Before joining SPHS, I spent a decade as an epidemiologist with the Government of Canada. There, my work involved extensive knowledge translation, bringing research into Canadian and international public health practice, and creating a wide network of knowledge users, practitioners and researchers with whom I still collaborate.

I currently serve on the World Health Organization’s Foodborne Disease Epidemiology Reference Group, and the Editorial Boards for Epidemiology & Infection and Foodborne Pathogens and Disease.

Graduate supervision and student opportunities

I am currently accepting applications from graduate students with a strong academic record in epidemiology, and either statistics or qualitative methods and research interests related to:

  • Foodborne diseases and food safety
  • Systems approaches to food and health
  • Knowledge synthesis and public health practice

Graduate studies application details 

Teaching interests

  • Epidemiology, including environmental and infectious disease epidemiology
  • Foodborne, waterborne, and enteric diseases
  • Burden of illness methods
  • Public health practice, including surveillance and outbreak investigations
