My research addresses the role of social media and their data in political processes, with a focus on political communication, public opinion, and gender. My published work examines how three groups – political actors, the press, and the public – use social media in regards to politics, how that social media use impacts their behavior, and how the policies and actions of social media companies in turn impacts political communication on their sites. I take up diverse methodologies like surveys, experiments, and large-scale computational and network analysis, as well as qualitative methods like in-depth interviews, to understand political events in socially networked digital spaces. My work aims to bring insights about and new theories of emerging political communication and public opinion in hybrid media and political systems.

I’ve published seventeen articles in peer-reviewed journals including the Journal of Communication, New Media & Society, Political Communication, Journalism, and Information, Communication & Society, and I co-edited a book (with Dr. Talia Stroud), Digital Discussions: How Big Data Informs Political Communication. I regularly present my work at conferences like ICA, APSA and AEJMC, and have received five Top Paper awards. In 2018, my dissertation was awarded the Lynda Lee Kaid Outstanding Dissertation Award from the National Communication Association.
