Abstract: Karen Bierman is a Distinguished Professor of Psychology and Director of the Child Study Center at The Pennsylvania State University. Her 28-year research career has focused on social-emotional development and children at risk, with an emphasis on the design and evaluation of prevention programs that promote social competence, school readiness, positive intergroup relations, and that reduce aggression and violence. She was the founding director of the Children, Youth, and Families Consortium at Penn State, and has also served as director of Penn State's Social Science Research Institute. Dr. Bierman directed the Pennsylvania site of the Fast Track Program. Currently, she directs two NIH-funded prevention research projects focused on promoting the school readiness of at-risk children, and she co-directs a predoctoral training program funded by the Institute of Educational Sciences (IES). Dr. Bierman is particularly interested in the implications of developmental research for the design of school- and community-based prevention programs, and in the evaluation and diffusion of empirically-based prevention programs that enhance school readiness, social-emotional competence, and reduce problem behaviors.

Max Crowley is an Assistant Professor at Pennsylvania State University studying the economics of investing in healthy development. He directs the Prevention Economic Planning and Research Labs within the Department of Human Development & Family Studies. The lab's work is generally focused on preventing illness and criminal behavior through evidence-based investments in childhood and adolescence. This includes utilizing advanced analytic designs, administrative data and technological solutions to optimize preventive strategies.

Crowley's work sits at the intersection of human development, economics and public policy. The research focuses primarily on (1) strengthening economic evaluations of preventive interventions, (2) facilitating evidence-based policy-making through strategic investments in preventive services, and (3) evaluating the utility of performance-based financing to access new resources for improving health.

His research is funded by the National Institute of Drug Abuse, National Institute of Nursing Research and the National Institute of Child Development, as well as the Doris Duke and the Robert Wood Johnson.

Kenneth A. Dodge is the William McDougall Professor of Public Policy and Professor of Psychology and Neuroscience at Duke University. He directs the Duke Center for Child and Family Policy, which is devoted to finding solutions to problems facing youth in contemporary society, through research, policy engagement, service, and education. Professor Dodge earned his bachelors degree at Northwestern University in 1975 and his Ph.D. in clinical psychology at Duke University in 1978.

Professor Dodge studies how problem behaviors such as chronic violence, school failure, drug use, and child abuse develop across the life-span, how these problems can be prevented, and how communities can implement policies to prevent these outcomes and instead promote children’s healthy development. He conducts longitudinal studies of children across their lifespan to understand how problems develop. He has developed, implemented, and evaluated several intervention programs that are based on this research. He teamed up with colleagues to create, implement, and evaluate the Fast Track Program to prevent chronic violence in high-risk children. He is now leading the Durham Family Initiative to prevent child abuse in Durham, North Carolina. He is also interested in developing and evaluating public policies to achieve community impact for the prevention of violence in youth and families. Curriculum Vitae pdf
