Colin Henry, PhD
I'm a political scientist working on problems at the intersection of political violence and digital communication technologies. I use computational methods, network analysis, and digital ethnography to answer questions about political extremism, social media platforms, community structure, and our relationship to technology. Download my CV (PDF) here.
Current status: I'm a post-doctoral research fellow at George Washington University. I completed my PhD at Vanderbilt University in September 2023.
Dissertation project: Three papers exploring the structural sources of political extremism in online communities. I argue that community competition, shaped by the architecture of platform governance, drives community radicalization. I use computational and digital ethnographic methods (and two novel datasets) to support my argument.
