My research focuses on two broad areas: legislative institutions and political methodology. My current research (with Gary Hollibaugh and Jonathan Klingler) explores how personality and ideology come together to shape legislative behavior. We have developed the first-ever estimates of legislator personality over time and show how these predict a wide range of legislative behavior. This project is an inherently interdisciplinary enterprise, drawing insight from political science, psychology, experimental economics, and machine learning.
Other research interests and projects focus on using machine learning, Bayesian approaches, and item response models to study legislative behavior and the extent to which elites are representative of the preferences of the masses.
