The lab’s research focuses on understanding and improving community health behaviors. Dr. Sisson studies how physical activity, sedentary behavior, nutrition, and screen use—and their physical and social environments—influence health across the lifespan. Her work examines food access, movement opportunities, and youth development, using epidemiologic research, interventions, and program evaluation, often in partnership with Native American communities and populations facing health disparities. A central emphasis is on young children and caregivers to promote equitable, sustainable health-enhancing environments.
