Ruopeng An conducts research to assess environmental influences and population-level interventions on weight-related behaviors and outcomes throughout the life course. In particular, his work assesses socioeconomic determinants and policies that impact individuals' dietary behavior, physical activity, sedentary lifestyle, and adiposity in children, adults of all ages, and people living with a disability.
The goal of An's research has been to develop a well-rounded knowledge base and policy recommendations that can inform decision making and the allocation of resources to combat obesity.
An's numerous publications include articles in journals such as the American Journal of Preventive Medicine, Obesity Reviews, Social Science & Medicine, and Pediatric Obesity. His research has been widely featured in media, including Time, the New York Times, Los Angeles Times, and CNN. In 2015, he received the Judy K. Black Early Career Research Award from the American Academy of Health Behavior. In 2018, he was elected as Fellow of the American College of Epidemiology.
Before joining the Brown School, An was an associate professor at University of Illinois at Urbana-Champaign.
