Professor Jon Roozenbeek

Jon Roozenbeek is a Lecturer in Psychology and Security at King's College London, Department of War Studies.

Jon works on the psychology of intergroup conflict and (digital) media effects. His research comprises two major themes: modern propaganda and intergroup conflict (with a specialisation in the Russian-Ukrainian war), and understanding and countering misinformation, disinformation, and extremism. He has written two recent books: The Psychology of Misinformation and Propaganda and Ideology in the Russian-Ukrainian War.

At War Studies, Jon is part of the NIHR Health Protection Research Unit (HPRU) in Emergency Preparedness and Response.

He was the British Academy Postdoctoral Fellow at the Cambridge Social Decision-Making Lab. He is also an Affiliated Lecturer in the Department of Psychology. His research focuses on misinformation, vaccine hesitancy, online extremism and inoculation theory. As part of his research, he co-developed the award-winning fake news games Bad News, Harmony Square and Go Viral. Jon is also interested in social media research, agent-based modelling and natural language processing. His doctoral dissertation (University of Cambridge, 2020) examined media discourse and identity during the Donbas War in eastern Ukraine.
