Biography
I am interested in the neural mechanisms underlying decision-making in humans, in individual differences in these mechanisms, and in the possible contribution of decision traits to pathological behavior. Our research focuses on decision-making under uncertainty, and on value learning and encoding. To study these topics we combine behavioral economics methods with functional MRI, as well as eye tracking and physiological measurements.

Research
Overview
- Risk and ambiguity in the negative domain – examining behavior and neural activation for decision in terms of risk and ambiguity between outcomes that include losses.
- Behavior and neural correlates of decision under risk and ambiguity across the lifespan.
- Decision parameters in obese and lean individuals – comparing attitudes towards decision parameters such as risk and ambiguity in different BMI groups.
- Implicit learning of value - behavior and neural correlates of value learning in conditioning paradigms and their relationship to choice processes.
- Representation of food in obese and lean subjects - how is food that is depicted in movies perceived and how does it affect choice.
