Dr. Jessri’s research program is uniquely at the intersection of nutritional sciences and population and public health. The overarching goal of her research program is to provide the evidence-base and decision tools to inform nutritional guidelines and polices for reducing the burden of chronic diseases.

Currently, Dr. Jessri’s program is focused on:

  • Dietary pattern modelling and health and healthcare outcomes (with a focus on systems approach)
  • Population health impact assessment of foods, nutrients, dietary habits and policy
  • Nutritional monitoring and population surveillance
  • Development of robust methods and strategies for addressing the challenges in assessment and analysis of complex dietary and lifestyle data
  • Design and development of personalized nutrition risk assessment tools

Dr. Jessri’s research lab offers a stimulating place for research on nutritional epidemiology for population health. If you are interested in joining the team, please contact us via email to express your research interests.
