Philip D. Waggoner

Welcome! My name is Philip Waggoner and I am a Visiting Assistant Professor in the Department of Government at the College of William & Mary.

My research focuses on the behavior of those with political power. Taking shape in interactions amongst American democratic institutions, as well as between elected officials and their constituents, I use a variety of statistical techniques (and interactive data visualization) to address questions related to representation, decision making, and institutional behavior. My research has been supported by the Office of the Director of National Intelligence (ODNI), the Intelligence Advanced Research Projects Activity (IARPA), the Institute for Humane Studies at George Mason University, the William A. Steiger Fund for Legislative Studies and the Centennial Center of the American Political Science Association.

I received my Ph.D. and M.A. in Political Science from the University of Houston, an M.P.A. from the School of Public Affairs at the University of Colorado, Denver, and a B.A. in Political Science from Colorado State University. For more information, see my CV.



I also enjoy writing R packages and am an occasional contributor at R-Bloggers. To date I have released: hhi (with a blog post), for calculation and visualization of Herfindahl-Hirschman Index scores; purging (with a blog post, reposted here), to address mediation effects among independent variables; and for fun, mlbstats, which is a player metrics calculator for a host of statistics from base-running and batting, to fielding and pitching. Several of my other projects and packages in process are available at my GitHub. Enjoy and send any bug catches my way!
