Research Summary

Keith Burghardt's main research interests are in misinformation, extremism, and complex growing systems. The former two research fields combine computational social science, natural language processing, and psychology to understand the role social media plays in changing user behaviors. This includes how people are susceptible to misinformation or radicalization, as well as why people join or stay in online hate groups, the offline impacts of online radicalization, and how we can encourage people to leave hate groups and de-radicalize. The latter research field utilizes geospatial analysis, network science, and physics to understand emergent phenomena of growing systems. These findings are being actively applied to understand how extremist social networks grow.
