My research focuses on two broad areas: legislative institutions and political methodology. My current research explores the linkages between partisan institutional arrangements in legislatures and legislative voting behavior. Specifically, I am interested in how theories of partisan influences on lawmaking shape the complex decision processes of legislators. At the moment, I am working on an estimation procedure that allows scholars to disentangle the partisan and electoral effects on legislators' voting records.
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.
