I am a Professor in the Department of Political Science part of the College of Arts and Science at Washington University, and the Director of the Center for Applied Statistics.  My research applies Bayesian modeling and data analysis (decision theory, testing, model selection, elicited priors) to questions in general social science quantitative methodology, American political behavior and institutions, focusing on Congress, the bureaucracy, and voters, using computationally intensive tools (Monte Carlo methods, MCMC, stochastic optimization, non-parametrics).

In 2006, I was host (at UC-Davis) of the Summer Methods Meeting July 20-23. The conference program is still online.  See also:  photo set 1 and  photo set 2.

For the 2006-2007 academic year I was on leave at Harvard. I still have a dedicated web page  there.
