I have broad research interests in pediatric nutrition, including school-based interventions, child/adolescent health and development, health disparities, and nutrition policies.  I currently have a K01 Mentored Research Scientist Development Award from the National Institutes of Health (NIH) to examine the influence of quick-service restaurants on children’s diets.  My research also focuses on innovative strategies to encourage the consumption of healthier school foods, the impact of school-based nutrition policies on children’s consumption of competitive foods (e.g. vending and à la carte snacks), and the association between diet and cognitive functioning.  Prior to coming to Harvard, I was an ORISE Policy and Science fellow at the Centers for Disease Control and Prevention in the Division of Nutrition and Physical Activity.
