I am an Assistant Professor in the Department of Government at Dartmouth College. I study political behavior and public opinion, examining how partisanship and information from political elites affect the behavior of citizens. My work focuses on understanding where partisan biases originate, where they manifest (inside and outside political domains), and their bounds.
