Biography

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.

Before joining King’s, Jon held research positions at the University of Cambridge, where he worked on the psychology of misinformation and developed and tested interventions (such as online games) to counter common forms of manipulation. He holds a PhD in Slavonic Studies (2020), also from the University of Cambridge. His thesis examined media and identity building in wartime Donbas.
