Research Interests
My research focuses on the neural mechanisms of cognitive control, namely how humans monitor and flexibly direct their own behavior to achieve complex goals. I have used a variety of methodologies, including single-unit neurophysiology in awake behaving primates, studies of behavior and individual differences, functional neuroimaging, and computational neural modeling to provide unified accounts of neurophysiology, fMRI, and behavioral data. My current focus is on the neural mechanisms of error likelihood prediction and risk perception in decision-making, using combined fMRI and computational neural modeling.
