My research is focused on human cognition and brain mechanisms relevant for learning and decision-making under uncertainty. Iím interested how personality factors such as impulsiveness or novelty seeking are related to individualís decision-making and goal-directed behaviour in uncertain environments. I use behavioural testing, fMRI and computational modelling techniques to describe behaviour. Computational models apply reinforcement or bayesian learning models to mimic and predict human behaviour based on actual performance. I look at individual individual differences between humans based on the modelling and the validity of those models for predicting real behaviour. I apply these techniques to investigate the cognitive and neurobiological foundations of why some people start new venture and companies over and over, whereas others do not.
