Research

My research focuses on both substantive and methodological questions. My substantive interests are primarily within comparative political behavior and political economy. Specifically, I am interested in understanding how electoral behavior is affected by economic and political institutions with a particular interest in economic voting and compulsory voting. I supplement this with methodological research questions focused on the ways we can improve our ability to estimate and interpret regression models with a particular emphasis on time-series, spatial, and panel data. I also have a methodological interest in instrumental variable and related designs; I seek to understand the conditions under which these designs are appropriate and produce reliable causal estimates.
