Department of Sociology
The University of North Carolina, Chapel Hill

Kathleen Mullan Harris (Chair), is the James E. Haar Distinguished Professor of Sociology, Adjunct Professor of Public Policy, and Faculty Fellow at the Carolina Population Center at the University of North Carolina at Chapel Hill. Her research focuses on social inequality and health with particular interests in family demography, the transition to adulthood, health disparities and family formation. Dr. Harris is Director and Principal Investigator of the National Longitudinal Study of Adolescent to Adult Health (Add Health), a longitudinal study of more than 20,000 teens who are being followed into adulthood. Under her leadership, the study has pioneered innovative study designs and integrative multidisciplinary research to understand social, environmental, behavioral, biological and genetic linkages in developmental and health trajectories from adolescence into adulthood. She has been an advocate within the social science and population disciplines for bridging social and biomedical sciences to advance knowledge on the development of health disparities from both an inter- and intra-generational perspective to inform public health and social policy. Her publications appear in a wide range of disciplinary journals including demography, genetics, family, epidemiology, biology, public policy, survey methodology, medicine, and social and health behavior. Dr. Harris serves on several national advisory boards of leading NIH studies as well as on the National Advisory Committee on Racial, Ethnic, and Other Populations of the Census Bureau. She received her doctorate in demography from the University of Pennsylvania. Dr. Harris was awarded the Clogg Award for Early Career Achievement from the Population Association of America in 2004 and the Warren E.
