Interests & Expertise

Dr. Ann Swartz’s research interests center on obesity; in particular, the health benefits of physical activity for overweight and obese individuals including 1) relationships between physical activity, health and obesity level, 2) novel translational physical activity interventions to improve health for overweight and obese individuals, and 3) the accurate assessment of physical activity behavior.
