Knox brings 25 years of experience to the study and evaluation of social programs, with special expertise in how support services for low-income parents — including child support, financial incentives, and services to strengthen family relationships — affect families and children. Her methodological interest is in designing new approaches to implementation research that will inform the expansion of effective programs. She is currently project director of the Building Bridges and Bonds evaluation, studying three innovative new components for responsible fatherhood programs. She is also co-project director of two evaluations of home visiting programs — the Mother and Infant Home Visiting Program Evaluation (MIHOPE), which is assessing the federal Maternal, Infant, and Early Childhood Home Visiting Program, and MIHOPE-Strong Start, which is examining the effects of home visiting on birth outcomes and maternal and infant health care use. She previously directed the Supporting Healthy Marriage project, a federally funded evaluation of interventions aimed at improving child well-being by strengthening the relationships of married couples; the Next Generation project, a collaborative, multidisciplinary initiative to study welfare-reform programs’ impacts on the well-being of children and families; and the evaluations of the Minnesota Family Investment Program and the Parents’ Fair Share demonstration. Knox has direct knowledge of welfare systems, having been special assistant to the executive deputy commissioner for income maintenance in New York City’s Human Resources Administration, where her responsibilities included estimating the costs of welfare-reform programs. The author of numerous reports and papers, Knox has a doctorate in public policy from Harvard University.
