Research Interests

Decision-making is ubiquitous, and the animal’s ability to learn the structure of its environment and thereby produce a series of actions that will maximize the overall reward is essential for survival. Our research focuses on the role of the primate prefrontal cortex and the basal ganglia in evaluating the outcomes of the animal’s choices and incorporating this information to improve decision-making strategies. We develop novel behavioral paradigms that can probe the core processes of decision-making, such as temporal discounting and integration of gains and losses. These behavioral studies are then combined with multi-channel neurophysiological recordings and pharmacological manipulations. These studies are highly inter-disciplinary, capitalizing on the insights from formal theories of economics and reinforcement learning as well as computational neuroscience of neural coding and behavioral studies of decision-making. Overall, our experiments seek to unravel the biological basis of planning and willful actions.
