Kathleen Mullan Harris, Chair

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. Miller Award for Meritorious Service to the Social Sciences from ICPSR in 2013.

Recognized for her groundbreaking work in the field of social epidemiology, she is noted for identifying the effects of social networks on mortality risks that helped define the field in the late 1970s. Dr. Berkman also broadened the field with her investigations of how social conditions related to inequality, race, ethnicity, and social isolation influence health and aging. Her research has been oriented towards understanding inequalities in health related to socioeconomic status, different racial and ethnic groups, and social networks, support and isolation. The majority of her work is devoted to identifying the role of social networks and support in predicting declines in physical and cognitive functioning, onset of disease and mortality. She has devoted much of her work to understanding determinants of population health by comparing European countries with the U.S. She is a member of the Conseil Scientifique de l’Institut de Recherche en Sante Publique (IReSP) in France. Dr. Berkman is the author of several books and over 200 publications. She co-edited Social Epidemiology, the first textbook on the topic, plus Neighborhoods and Health (both with Ichiro Kawachi).

Michael Rosenfeld
Stanford University
Michael J. Rosenfeld is an associate professor in the Department of Sociology at Stanford University. He studies race, ethnicity, and family structure, the family’s effect on children, and the history of the family. He is interested in mate selection as a social as well as a personal process. Dr. Rosenfeld is the author of many scholarly articles, along with the 2007 book The Age of Independence: Interracial Unions, Same-Sex Unions, and the Changing American Family. In The Age of Independence, Rosenfeld argued that delayed age at first marriage, higher education, and the residential independence of young adults from their parents has reduced parental control over their children’s mate selection. As a result of decreased parental oversight, young adults are forming more interracial unions, and more same-sex unions. He is the principle investigator of the How Couples Meet and Stay Together (HCMST) study, a nationally representative longitudinal study of couples funded by the National Science Foundation. Dr. Rosenfeld is also the winner of three teaching awards.
