I am the Managing Director of the Nutrition, Health, and Human Services division at Mathematica, overseeing our work in nutrition, children's early learning, criminal justice, pubic and behavioral health, maternal and child health, family strengthening, and economic empowerment. We work closely with the Food and Nutrition Service (FNS) within the U.S. Department of Agriculture and with many operating divisions and offices within the Department of Health and Human Services, including the Administration for Children and Families (ACF), Health Resources and Services Administration (HSRA), Agency for Healthcare Research and Quality (AHRQ), Substance Abuse and Mental Health Services Administration (SAMHSA), and the Office of the Assistant Secretary for Planning and Evaluation (ASPE).  

I specialize in food and nutrition policy and employment and training programs. My research focuses on federal nutrition assistance programs, including the Supplemental Nutrition Assistance Program (SNAP) and the Older Americans Act Title III-C Nutrition Services Program, as well as community-based emergency food programs. Much of my work focuses on low-income households' decisions to participate in these programs, to find and retain employment, and to address barriers to ensuring job security and adequate access to food.

My recent work includes evaluations of innovative strategies to help SNAP participants increase employment, earnings, and food security; assessments of the effects of mobile payment pilots that allow SNAP recipients to pay for food using their personal mobile devices instead of a SNAP Electronic Benefits Transfer (EBT) card; evaluations of interventions for childhood obesity; and studies of geographic access to food for low-income families.
