Biography

My lab studies cognition in the context of sleep deprivation and healthy cognitive aging. The common thread linking these seemingly unrelated themes is the goal of furthering human cognitive performance through an understanding of the mechanisms that underlie performance degradation in these settings. My lab has contributed to a better understanding of the neural correlates of cognitive alterations associated with short-term total sleep deprivation (TSD) on healthy young adults Using a combination of behavioral tests, EEG and functional magnetic resonance imaging (fMRI), we have probed the mechanisms underlying reduced attention and processing capacity as well as changes to decision making and valuation. We have probed the imaging correlates of inter-individual variation in performance when volunteers are under sleep deprived. We seek to extend this work to partial sleep deprivation and to evaluate the benefits of sleep extension on cognition and human health.
