I am a second year doctoral student in Nutritional Epidemiology at HSPH. I also earned a ScM degree in Epidemiology at HSPH. My research interest focuses on investigating effective and efficient interventions to promote health behavior, including physical activity and healthy eating, and targeting at individual factors as well as social factors, including built environment and information environment, especially in developing countries. I also looked at peer effect on health behaviors among college students, with an aim to investigate how to utilize peer effect to design health behavior interventions.
