We welcome as a new occasional contributor Eric Patashnik, Professor of Public Policy and Politics at the University of Virginia. Eric’s research focuses on public policy, especially health care and social welfare. His books include Reforms at Risk: What Happens After Major Policy Changes Are Enacted. With Alan Gerber, he is currently finishing a book tentatively entitled Unhealthy Politics: Professional Authority, Partisan Polarization, and the Battle Over Evidence-Based Medicine. His guest posts for us are here, here, here, here, and here. We’re glad to have him aboard!
