I am an Assistant Professor in the Political Science Department at the University of Denver.  My specialty is American Politics, specifically the study of Congress and how it has changed as Democrats and Republicans have become more polarized.

I also study Colorado politics and co-led the University of Denver’s first Colorado Voter Poll in the 2012 election. I am particularly interested in sources of political change in Colorado.     

I received my Ph.D. from the University of California, Berkeley in 2010 and my A.B. from Harvard University in 1995.  From 1996 - 2002, I served on the staff of Senate Democratic Leader Tom Daschle (D-SD).  My areas of focus were appropriations and environmental policy.
