I am associate professor of political science, adjunct associate professor of statistics, and core faculty member of the Center for Statistics and the Social Sciences at the University of Washington, Seattle.
My research in political economy and comparative politics ranges over many topics: the politics of monetary policy, the politics of bureaucratic power, the politics of budget trade-offs, and the comparative study of institutions governing health.
I specialize in the visual display of scientific information, particularly the illustration of substantive findings from statistical models. I’m also interested in statistical inference on data whose logical bounds make estimation easier (or simply possible), as in the study of political rank, compositional data (such as budget categories), and ecological inference.
I serve as an expert witness on the use of statistical methods to resolve contested elections and have consulted in many disputes over the racial and political consequences of legislative redistricting.I also consult on matters relating to statistical methodology and data visualization.
