Research

We study emotion regulation and decision making in healthy individuals and in a wide range of psychopathologies, including their development. We apply several neuroimaging techniques combined with pharmacological interventions and psychophysiological assessments to improve mechanistic understanding of how people regulate automatic action tendencies as well as instrumental approach-avoidance decisions.

Main Projects and funding:

  • Decisions under threat. How can we model and optimize decisions under threat in health and social anxiety? (DARE2APPROACH: ERC-Consolidator).

  • Dynamic Modelling of resilience. Within a large European consortium we aim to test the dynamics of stress-resilience (Dynamore: EU Horizon2020).

  • Police in Action. Can we predict development of post-traumatic stress-symptoms in police officers? Check out this prospective study (NWO-VICI).

  • Enhancing decisions under stress through VR-based biofeedback training (BIOCHILL: NWO-Brain & Cognition).

  • Nijmegen Longitudinal Study. With Developmental Psychology, we study the effects of early and later life events on brain development (ERC-StG).

  • Using brain stimulation to alleviate fear. We use tACS and pioneer with ultrasound stimulation within the national (INTENSE: NWO-Crossover).
