Borradaile contributes her expertise to projects in nutrition and education. She is the survey director for the evaluation of the Harlem Children’s Zone’s Healthy Harlem Program, an obesity prevention and treatment program for about 8,000 students being implemented in early child care programs, charter schools, and after-school programs. She served as the deputy survey director for an evaluation of Playworks, a physical activity program for elementary schools, helping to develop a gold standard approach to data collection and training data collection staff. Borradaile is also a topic area lead and lead methodologist for the What Works Clearinghouse (WWC), an initiative of the U.S. Department of Education’s Institute of Education Sciences to identify evidence-based programs and practices in education. She was also the survey director for a Food and Nutrition Service project that developed and tested simplified tools for monitoring school food authorities’ compliance with new meal requirements.


Borradaile joined Mathematica in 2010 from Temple University, where she studied school-based obesity prevention efforts in Philadelphia. She is a reviewer for numerous journals, including Health Psychology, the Journal of the American Medical Association, the New England Journal of Medicine, Obesity, and Pediatrics. She holds a Ph.D. in policy research, evaluation, and measurement from the University of Pennsylvania.
