个人简介

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.
