Jonas received his PhD in 2015 from Ghent University. Before joining Tilburg University, he conducted postdoctoral research at KU Leuven, Ghent University, and Yale. His research is dedicated to creating a better understanding of psychopathology with the goal of developing more efficacious interventions and alleviating the societal burden. Going beyond traditional approaches that focus on individual risk factors alone, he integrates several methods and levels of analysis to elucidate the intricate interplay of multiple causal risk factors contributing to depression and anxiety. He uses this understanding to develop better theories and identify opportunities for prediction, detection, and intervention. In 2021, Jonas received the Rising Star Award from the Association of Psychological Science. Additionally, Jonas is an honorary research fellow at King's College London.
