Neurobiological Mechanisms of Cognitive Control

I am interested in the neurobiological mechanisms that underlie cognitive control, decision making and reinforcement learning in humans; related interests include the study of impulsivity, continuous motor control, and spatial navigation. To investigate these issues I adopt a variety of empirical and theoretical approaches including event-related brain potential, functional magnetic resonance imaging and computational modelling techniques, as well as experiments with atypical populations such as substance dependent individuals and children with attention deficit hyperactivity disorder.
