Research field

Why do we think and behave the way we do? Accumulating behavioral evidence suggests that the sleeping brain plays a critical role in our thoughts and actions. However, little is known about the ways the sleeping brain accomplishes this work. In my lab, we develop and integrate various neuroimaging (e.g. 3T and 7T MRI), physiological (polysomnography including EEG), and psychophysics techniques to elucidate the fundamental role of the sleeping brain in human cognition and behavior.
