Jon Roozenbeek is Director of the Influence and Technology Lab (ITLab), which sits between Cambridge's Department of Psychology and the Department of Communication Science at the Vrije Universiteit Amsterdam. His research focuses on (mis)belief formation, intergroup conflict (particularly in Russia and Ukraine), polarisation, underground manipulation markets, and the use and misuse of modern communication technologies. He holds a PhD in Slavonic Studies (2020), also from the University of Cambridge, for which he studied propaganda and ideology-building in Russian-occupied Donbas (Ukraine). Jon has authored two recent books with Cambridge University Press: The Psychology of Misinformation (with Sander van der Linden) and Propaganda and Ideology in the Russian-Ukrainian War. In addition, he has written more than 70 peer-reviewed publications, published in journals including Science, Nature, Nature Human Behaviour, Nature Communications, Nature Computational Science, PNAS, and Psychological Science. His work has been awarded numerous distinctions, including the 2024 Rising Star Award (Association for Psychological Science) and the 2025 Jim Sidanius Early Career Award (International Society of Political Psychology), and he is among the ISI top 1% most-cited scientists worldwide.
