I am an Assistant Professor of Political Science at Northeastern University, a core faculty member of the NULab for Text, Maps and Networks, and a core faculty member of the Network Science Institute. My research examines how political opinions form and change as a result of discussion, deliberation and argument in domains such as legislatures, campaigns, social media, and the judiciary, using techniques from machine learning, automated text analysis, and social network analysis.
