The Catalyzing Communities team comprises leading researchers and dedicated staff committed to helping populations around the country jump-start community-level obesity prevention.
Based at the Friedman School of Nutrition Science and Policy, at world-class research institution, Tufts University—where innovation and interdisciplinary collaboration are the foundations of discovery—we bring decades of experience, research, and real-world impact in the areas of nutrition, physical activity, behavior change, community interventions, systems science, and more. Catalyzing Communities is an initiative within ChildObesity180.
Our work is made possible through the collaborations and partnerships we have across communities and institutions that enable us to do our best work and make meaningful impact.
