I am a psychologist and cognitive neuroscientist who is interested in the neural mechanisms of human decision making and their interactions with the external world.
Starting from a reinforcement learning perspective of behavior, I ask how we establish links between actions and outcomes (credit assignment) in the first place or incorporate internal representations (model-based reinforcement learning) to aid learning, especially when the environment is ambiguous, uncertain, and volatile. In order to investigate these questions, I combine multiple methods, such as experimental control, electrophysiological recording as well as computational modelling.
Together with Prof. Sander Nieuwenhuis I am currently investigating the role and impact of norepinephrine on value-based decision making and reinforcement learning.
