Research Overview

We know ourselves less than we expect because most information processing in the brain occurs without our consciousness. Our lab is broadly interested in how we recognize (cognition), how we decide (decision-making), and how we change through experience (learning) with an emphasis on interactions between conscious and subconscious processing in the human brain. We take an interdisciplinary approach including psychophysics, neuroimaging, machine learning, and computational modeling.
