Jonathan acquired his background in Psychology (BSc) and Cognitive Neuroscience (MSc) at the Radboud University in Nijmegen. During his Master’s program, he worked as a Research Assistant in the Cognitive Affective Neuroscience lab, led by Prof. Erno Hermans. In this role, he contributed to the ‘Dynamic Modelling of Resilience’ (DynaMORE) project, gaining experience in Ecological Momentary/Physiological Assessments. Additionally, he assisted in study management and data collection for the ‘Cortisol for PTSD’ project, exploring potential pharmaceutical targets for treating Post Traumatic Stress Disorder. During his thesis project, Jonathan created a computational model of the laboratory-induced cortisol stress response in collaboration with the Stress-EU consortium. After defending his thesis project “Developing Novel Measures of the Cortisol Stress Response Using Mathematical Modelling Leveraging the STRESS-EU Database”, Jonathan joined the EPAN lab in the role of PhD student in 2023. Within the EPAN lab Jonathan works on the ‘Decision under Stress’ project in which we leverage a virtual reality game with real-time biofeedback to operantly condition police officers to perform slow-paced breathing in an active and engaging context. Here, he aims to achieve a better understanding of the mechanisms driving the positive effects of biofeedback applications.
