I am the Bloomberg Distinguished Professor of Sociology and Education at Johns Hopkins University. I received a Ph.D. in Sociology from Harvard University in 2000, an M.Phil. in Comparative Social Research from Oxford University in 1995, and a B.A. in Sociology from Harvard University in 1993. I began my career in the Department of Sociology at Cornell University, joining as an Assistant Professor in 2000 and leaving in 2014 after serving as the Jan Rock Zubrow ’77 Professor in the Social Sciences.

My current areas of research include education, inequality, demography, and methodology. In addition to many journal articles on these topics, I have published two books: On the Edge of Commitment: Educational Attainment and Race in the United States (Stanford University Press, 2005) and, co-written with Christopher Winship, Counterfactuals and Causal Inference: Methods and Principles for Social Research (Cambridge University Press, 2007; Revised and Enlarged Second Edition, 2015).
