United States

Members of our team have worked for decades on a wide array of nutrition research projects in the United States. Our current work focuses primarily on diet-related health disparities that can lead to higher risk of chronic diseases for some groups, including low-income, Black, and Latinx populations. We also study factors impacting child nutrition. More specifically, our U.S. research projects examine:

We have developed innovative methods and models to evaluate and inform the design of federal food assistance programs (e.g., WIC, SNAP) and nutrition policy interventions such as front-of-package labeling, food and drink taxes or subsidies, restrictions on junk food marketing, and other nutrition-related policies. These methods include pricing simulations that model the effect of different pricing policies such as taxes and subsidies on food purchases and nutritional outcomes and experimental grocery stores (both virtual and real-life).
