Laura Chiavaroli, PhD, is an Assistant Professor in the Department of Nutritional Sciences, Temerty Faculty of Medicine, University of Toronto and Affiliate Scientist at the Li Ka Shing Knowledge Institute, St. Michael’s Hospital. Dr. Chiavaroli’s research program addresses the important implementation gap between guidelines-based nutrition therapy for cardiometabolic diseases and effective strategies to mobilize them, while also addressing the equity gap. She leads large interdisciplinary teams in the co-design and testing of innovative implementation strategies leveraging the use of digital tools and randomized trials to drive effective policies and programs related to dietary patterns for cardiometabolic disease across diverse communities. She also tests new policy enhancements to support adherence and demonstrates novel applications of methods to improve assessments of social and gender determinants of health, to identify communities to target and provide evidence to drive inclusivity in guidelines and advance health equity.

Dr. Chiavaroli has authored over 100 publications and holds several grants, including multiple grants from the Canadian Institutes of Health Research. She was recently awarded the 2025 IAFNS Emerging Leader Award and the 2024 American Society for Nutrition Mead Johnson Award for outstanding research from a young investigator.
