I am a neurobiologist interested in how groups of neurons work together to process information. My research has focused on the frontal cortex and basal ganglia and their roles in executive control and decision making. My laboratory uses a systems and computational approach and core methods include multi-electrode recordings, optogenetics, anatomical tract-tracing, multivariate statistics, and computational models of neural circuits. We are currently funded by the National Science Foundation to understand neural circuits that allow for "performance monitoring" (updating plans for action based on past behavioral outcomes) and the Klarman Family Foundation to understand neuronal circuits that control food-seeking behavior.
