Mary Kay Fox is a nationally recognized expert in nutrition, childhood obesity, and school food environments. She is also Mathematica's director for nutrition policy research.
Fox currently directs an evaluation of the Harlem Children’s Zone’s Healthy Living Initiative, an obesity prevention and treatment program implemented in child care centers, schools, and afterschool programs. She also directs the fourth School Nutrition Dietary Assessment study, a national study of school meal programs that is collecting data from more than 900 schools, and the Food and Nutrition Service WIC-Medicaid II project, which is assessing the impact of participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program on birth outcomes and Medicaid costs.
Widely published in peer-reviewed journals, Fox serves on two Institute of Medicine (IOM) committees, one to review the WIC food packages and another panel looking at the consequences of sodium reduction in different populations. Previous IOM work includes a committee to Review National School Lunch and School Breakfast Program Meal Patterns and Nutrition Standards as well as a similar IOM committee that completed comparable work for the Child and Adult Care Food Program. In addition, she is a member of “The B-24 Project,” a working group that aims to evaluate the evidence base to support inclusion of infants and children under the age of 2 in The Dietary Guidelines for Americans. Fox holds a master’s of education with a concentration in nutrition from Tufts University.
