Research Interests

Having a burger or a salad for lunch? Spending money on stocks or funds? Donating money for charity or buying a new TV? Every day there are thousands of decisions we have to make, some we have to think about carefully and others we make rather intuitively. Not all of our decisions are optimal; a lot of people cannot resist and go for the burger although a salad would be better in the long run and others spend money on risky stocks and thereby lose a lot of money.

We investigate human cognition and structural and functional brain mechanisms to understand how decisions are made. We use functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), behavioral paradigms and biological markers in order to get a better understanding of the factors driving human decisions.
