We are interested in understanding why we make particular actions. Our goal is to understand the neural bases of these decision-making processes and how they are influenced by sensory and motivation information. Currently, we are focusing on understanding the flow of information through cortical and basal ganglia circuits, and how pathologies that alter decision-making, like addiction, disrupt this process. We take an integrative approach using mice, where we can combine both simple and sophisticated quantitative behavioral measurements, with powerful molecular and genetic tools and monitoring techniques to delineate molecular mechanisms within specific cell-types in identified circuits that control decision-making processes.
