I am an Assistant Professor at the University of Michigan.   I specialize in the study of the United States Congress, and I am especially interested in understanding congressional rules, the purposes they serve, and the conditions under which Congress will change them.  I also develop new quantitative methods for adapting techniques from machine learning for statistical inference.  Before coming to the University of Michigan, I was an American Political Science Association Congressional Fellow, where I was as an economic policy advisor to Senator Mike Lee.
