He currently heads the Decision Neuroscience group at the Donders Institute, and his research utilizes a novel approach to the study of both individual and interactive decision-making by combining the methods of behavioral experiments, functional neuroimaging, and formal economic models. Examining sophisticated high-level behavior at a neural level, such as deciding on how much risk to take with an investment or deciding on a strategy when playing a competitive game with an opponent, can provide important clues as to the fundamental mechanisms by which decision-making operates.

A further goal of his group is to use the knowledge gleaned from these studies to inform public policy debates, for example in understanding how expectations play a role in financial, environmental and health-care decisions, and has founded the Radboud Centre for Decision Science to advance these goals. He has published his work extensively in leading international journals across several fields (Psychology, Neuroscience, Economics and Business). His research has been funded by the National Institutes of Health, the National Science Foundation, the Dutch Science Foundation, and the European Research Council.

He is native of Dublin, Ireland, and when not in the lab enjoys travelling and outdoor pursuits such as football, running, biking (living in the Netherlands is a good place for these), as well as hiking, skiing and mountaineering (however not so good for these - though the mountains aren’t too far away).
