My research surrounds the theme of using modeling to integrate the evidence base to inform policy and practice guidelines. Specifically, I am interested in the distribution of modifiable risk factors (e.g. diet, exercise, and disease screening) and their joint implications on disease burden in the whole population and between demographic subgroups.
My research surrounds the theme of using modeling to integrate the evidence base to inform prevention policy and practice guidelines. Specifically, I am interested policy, economic and environmental approaches to modify behavioral risk factors (e.g. diet, physical activity, and other health behavior) and their impact on disease burden in the whole population and between demographic subgroups.
My research focuses on the obesity epidemic in adults and in children. I co-direct the Obesity Prevention Initiative at Columbia Mailman School of Public Health. My current research and collaboration aims to design, test, and evaluate various population-wide strategies and policies on their impact on energy balance, weight status, and downstream health consequences. One key aspect I have worked on is the intake of sugar-sweetened beverage among U.S. adults and youth. I led several projects to evaluate the health and economic impacts of population-level interventions to curb sugar-sweetened beverages, including levying excise taxes or imposing portion size restrictions as proposed in New York City.
In addition, I have led or guided research projects related to the cost-effectiveness assessments of various disease prevention practices, such as guidelines for blood pressure and cholesterol screening as part of pediatric services and the use of novel imaging technologies to screen for atherosclerosis in asymptomatic adults.
