My research interests span the fields of methodology and political behavior.  The questions that have motivated my research in both fields share a concern with the analysis of dynamic processes.  Methodologically, I have devoted much of my research to identifying and explicating methods appropriate for the analysis of dynamic processes so that analysts can reliably test hypotheses about change across subfields and increasingly across disciplines. Substantively, my contributions include findings on how both opinions and votes are affected by changing economic perceptions, economic conditions, and the political landscape. Other projects include work that examines the effects of issue framing on public opinion both on individual opinions and on mass opinion over time. The focus of this project is effect of the innocence frame on attitudes toward the death penalty. The cornerstones of my current research agenda are a large methods project that focuses on event history models for repeated events and projects dealing with the interaction of economic conditions and attitudes with political opinions and behavior.
