Biography

Welcome! I am an associate professor of politics and public affairs at Princeton University. I use quantitative and computational methods to study the relationship between digital media and politics.

Please see the Papers page for more information about my research, which explores questions such as:

  • To what extent do digital and social media facilitate encounters with political perspectives that differ from one’s own?
  • How prevalent is online misinformation, how commonly do people encounter it on social media, and what are its effects?
  • What is the relationship between social media and political outcomes such as polarization and trust?
  • How can social platforms improve knowledge and promote news diet quality?
  • How can researchers use survey and digital trace data to measure concepts related to digital media and politics?

I’m also a founding co-editor of the Journal of Quantitative Description: Digital Media, with Kevin Munger and Eszter Hargittai. You can read our essay introducing the journal’s philosophy and goals here.
