I use behavioral economics to investigate how individuals make decisions about their health, in particular how public policy and the environment affects obesity and related chronic disease. Using statistical and econometric methods and diverse data sources, including surveys, sales data, and administrative data, we seek to inform policy on obesity prevention.
I have investigated the role of the food environment and the built environment, including neighborhoods, on childhood obesity. I also study the impact of several public policies on health:
- policies mandating calorie labeling in restaurants
- food policies in schools
- New York City’s one-time proposal of limiting the size of sugar-sweetened beverages served in restaurants
- policies supporting the development of supermarkets in high-need areas
As the founding director of NYU Langone’s Comprehensive Program on Obesity, I am spearheading an initiative designed to determine causes of obesity and develop new treatment and prevention strategies. This institution-wide initiative features the DataBridge, an infrastructure for integrating data from population health, clinical, and basic science research using big-data analytics.
I also serve as chief of the Section on Health Choice, Policy and Evaluation in the Department of Population Health.
