Jonas is an Assistant Professor at the Department of Medical and Clinical Psychology. He received his PhD in 2015 from Ghent University. Before joining Tilburg University, he conducted postdoctoral research at KU Leuven, Ghent, and Yale University. He aims to understand how people make sense of ambiguous social situations and what happens if this goes awry. Jonas' research bridges cognitive, affective, and social science approaches to uncover the nature, causes, and effects of biased interpretations and inflexible belief revision to develop transdiagnostic and transtherapeutic models of psychopathology. He combines diverse methods and statistical techniques to capture toxic features of interpretation processes in the lab and in real life. Jonas is consulting editor at Journal of Abnormal Psychology and associate editor at Journal of Experimental Psychopathology. In 2021, Jonas received the Rising Star Award from the Association of Psychological Science.
