Donald P. Green (Ph.D., University of California at Berkeley) is Professor of Political Science at Columbia University. The author of four books and more than one hundred essays, Green's research interests span a wide array of topics: voting behavior, partisanship, campaign finance, hate crime, and research methods. Much of his current work uses field experimentation to study the ways in which political campaigns mobilize and persuade voters, but he has also conducted experimental research on the effects of the mass media, civic education classes, and criminal sentencing. With Alan Gerber, he recently co-authored a textbook on this research method titled Field Experiments: Design, Analysis, and Interpretation (W.W. Norton, 2012).

Allison J. Carnegie is a Ph.D. candidate, pursuing a joint degree in the Departments of Political Science and Economics at Yale University.

Her work has appeared in the American Journal of Political Science and she has been awarded the J. Jacueline and Roger B. Kaufman Fellowship, the Falk Fellowship, and the Yale University Dissertation Fellowship.
