Our primary interest is in understanding the evolution, function and disorders of REM sleep.

A major focus of the laboratory is on the peptide hypocretin (orexin), whose loss is responsible for narcolepsy. Our work on the control of sleep and motor activity has relevance to an understanding of sleep apnea, REM sleep behavior disorder, restless legs syndrome and nocturnal bruxism.
