I am an assistant professor of politics and public affairs at Princeton University.

My research sits at the intersection of political communication, public opinion, and political behavior. I use a combination of experimental methods, large datasets, machine learning, and innovative measurement to study how people choose, process, spread, and respond to information about politics.

Current or recent projects investigate online selective exposure, how to accurately measure media exposure on the internet, the dynamics of interest group mobilization over Twitter, and the persuasive effect of new information on individuals’ attitudes and beliefs. See the Research page for more on these and other projects.
