Dr. Shor holds a Ph.D. in political science from Columbia University and is currently on leave from the University of Chicago, where he is an assistant professor at the Harris School of Public Policy Studies. His research focuses on ideology and political parties in American legislatures. One current project focuses on how well state legislatures and congressional delegations represent the ideological preferences of citizens at the micro and macro levels. Another seeks to find the roots of political polarization at the state level, as well as its policy consequences. He is interested in explaining the voting behavior of individual state legislators in health policy, and collectively, the vastly different choice states make.
