Assistant Professor & Adjunct Assistant Professor

Assistant Professor of Government
Director of Undergraduate Research, Program in Quantitative Social Science

I am an Assistant Professor in the Department of Government and the Program in Quantitative Social Science at Dartmouth College. I study political representation and partisanship, examining how legislators represent their constituents and how signals from legislators change both constituent and legislator behavior. In my work I develop novel experimental designs to show the causal effects of legislator action and partisanship on behavior. I contextualize these results with large-scale computational text analyses of legislator communication.
