Dr. Justine Keathley is a registered dietitian with the College of Dietitians of Ontario and an Assistant Professor in nutrition, exercise and metabolism at the University of Guelph. She completed her CIHR-funded PhD at Western University where she led a randomized controlled clinical trial evaluating the impact of providing genetic information on nutrition, exercise and health outcomes. She then pursued a CIHR-funded postdoctoral fellowship at Université Laval and a visiting postdoc with the Genomes to People Lab at Harvard University and Brigham & Women’s Hospital. During her postdoctoral fellowships, Dr. Keathley used various ‘omics’ technologies to study relationships between genes, nutrition, metabolites and health, and the interindividual variations that are observed. She is particularly interested in understanding the interplay between genetic variation, nutritional intake and health outcomes (nutritional genomics). Dr. Keathley is deeply passionate about evidence-based nutrition and was the lead author on the first clinical practice guidelines in nutritional genomics applications for omega-3 fatty acids and serum triglycerides. Her research program in HHNS at the University of Guelph focuses on evaluating potential metabolic and health impacts among carriers of inborn errors of metabolism.
