She has woven together experience in social policy, community building, education, and human service programs to become a US authority on “what works” to improve the future of disadvantaged children and their families and neighborhoods. 

Supported by the Annie E. Casey Foundation and the W.K. Kellogg Foundation, her Pathways Mapping Initiative (PMI), is attempting to develop new approaches to building a stronger knowledge base about what works in reaching such goals as school readiness, third grade school success, successful transition to young adulthood, and the prevention of child abuse and neglect.
