Greg Duncan is Distinguished Professor in the Department of Education at the University of California, Irvine. With a 1974 Ph.D. in Economics, Duncan spent the first two decades of his career at the University of Michigan working on, and ultimately directing, the Panel Study of Income Dynamics (PSID) data collection project, which, in 2001, was named by the National Science Foundation to be one of the 50 most significant NSF-funded projects in the organization’s history. Beginning in the late 1980s, Duncan engaged in a number of interdisciplinary research networks and began to focus on the impacts of family and neighborhood conditions on children’s cognitive and behavioral development. During his 1995-2008 tenure at Northwestern University, he was the Edwina S. Tarry Professor in the School of Education and Social Policy. He co-edited Neighborhood Poverty (1997), Consequences of Growing Up Poor (1997) and For Better and for Worse: Welfare Reform and the Well-Being of Children and Families (2001) and coauthored Higher Ground: New Hope for the Working Poor and Their Children (2007). Duncan was elected to the American Academy of Arts and Sciences in 2001 and the National Academy of Sciences in 2010. He was President of the Midwest Economics Association in 2004, the Population Association of America in 2008 and the Society for Research in Child Development (2009-11).
