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.
Additionally, I am working on a number of collaborative projects. The first of these is with Lawrence Rothenberg, in which we analyze the donation behavior of nonprofit foundations to environmental NGOs. Using social network analysis and zero-inflated log-normal utility threshold item response models, we are able to disentangle the motivations behind foundation giving and NGO adaptation. The other project includes a Facebook application for matching voters and legislators in a common ideological space, an experimental study on the effects of valence factors on candidate evaluations (co-authored with Jonathan Klingler and Gary Hollibaugh), and a project unifying survey and roll call approaches to the study of legislator-voter ideological matching.
