Professor and Vice Provost for Faculty Affairs
I am interested in the neural basis of higher cognitive function. Specifically, my research focuses on working memory, attention, and cognitive control as these are the building blocks of all cognitively complex behavior and thought. I use functional magnetic resonance imaging (fMRI), cognitive testing, and computational modeling to develop an integrated understanding of these dynamic neural systems, from the activity of single cells to behavior.
