Research Interests

The overarching goal of my research program is to characterize the psychological and neural systems underlying attention and working memory and to identify how these systems are coordinated to promote stable, flexible, and adaptive visually-guided behavior. I am also interested in how alterations in these systems may contribute to the cognitive and behavioral deficits observed in pathological conditions, such as schizophrenia. To address these issues, my lab uses a combination of behavioral, electrophysiological (EEG), neural stimulation (transcranial magnetic stimulation; TMS), and computational modeling techniques.
