Keri Lintz is a third-year PhD student at the UCLA Luskin School of Public Affairs, Department of Social Welfare. Her research addresses structural disadvantage by examining the ways in which public policies shape early foundations for healthy lifetime outcomes. Broadly, she studies how social policies support families and attend to factors that drive disparities in early childhood.

Keri is keenly interested in the careful and purposeful application of causal inference methods to child and family policy and serves as the manager for the UCLA Practical Causal Inference Lab. She is currently engaged in studies evaluating the effects of policies and programs on family financial stability, early childhood mental health, and access to healthcare.

Keri draws on almost two decades of experience and expertise in research, public policy administration, and social service delivery. Her first professional experiences were as a child welfare consultant and crisis intervention specialist. Subsequently, she worked for state government administering five federal grant programs designed to foster child and family well-being. Before joining UCLA, she was the executive director of the Center for Human Potential and Public Policy and The Behavioral Insights and Parenting Lab at The University of Chicago where she gained a deep appreciation for the capacity of rigorous research to inform sound policy, programs and practice. In this role, she provided leadership in the implementation of large-scale field experiments and evaluation of promising programs dedicated to reducing social and economic inequality.

Judith (Judy) Perrigo is an Assistant Professor in the Department of Social Welfare at the UCLA Luskin School of Public Affairs and serves as the Research Director for the Data Informed Futures (DIF) project at the UCLA Center for Healthier Children, Families, and Communities. Drawing on her clinical background supporting children and families in Los Angeles County, her scholarship and teaching center on prevention and early intervention (PEI) strategies to address structural inequities, particularly those affecting early childhood.

Dr. Perrigo’s research advances holistic wellbeing for children from birth to age five, with a focus on economic security, early learning environments, and health disparities. Her work aims to identify both protective and risk factors that shape developmental trajectories, applying an equity-centered PEI framework and leveraging qualitative, quantitative, and mixed-methods approaches tailored to each study’s goals.

Her current projects include studies using the Early Development Instrument (EDI) to track population-level trends in developmental health among kindergarteners, as well as multi-year randomized controlled trials examining the impact of unconditional cash transfers on early childhood outcomes. A key aspect of her work is ensuring that research findings are strengths-based, culturally responsive, and accessible to diverse audiences. Support for her work comes from the Conrad N. Hilton Foundation, Society for Research in Child Development, First 5 Orange County, the Council on Social Work Education, and Los Angeles County.
