SLEEP—it’s something we do (or try to do) every night because we feel tired and know how our behavior changes when we don’t catch enough zzz’s. Scientists, however, aren’t clear on the biology behind our compulsion to sleep, or even how regular snoozing benefits us. While already interested in circadian rhythm and the molecular basis of sleep, Amita Sehgal took her research to a whole new level after making a simple discovery: flies also need sleep. At this Weeknights at the Wagner lecture, Sehgal, a University of Pennsylvania Neuroscience professor, will share the latest findings from her lab, where they use the Drosophila melanogaster fruit fly as a model for human sleep and sleep-related behavior. 

Dr. Amita Sehgal is the John Herr Musser Professor of Neuroscience, Investigator of the Howard Hughes Medical Institute and Director of the Chronobiology Program at the University of Pennsylvania.  Dr. Sehgal received her Ph.D. from the Weill Graduate School of Cornell University and conducted her postdoctoral work at Rockefeller University. Her research focuses on the genetic basis of circadian rhythms and sleep, using primarily Drosophila as a model system. Dr. Sehgal has received many awards and honors, which include election to the National Academy of Medicine and the American Academy of Arts and Sciences.
