Charmane Eastman, PhD, is a professor in the Department of Psychiatry & Behavioral Sciences and the founding director of the Biological Rhythms Research Laboratory at Rush University Medical Center in Chicago. Her research interests include human circadian rhythms and sleep, with an emphasis on the man-made circadian rhythm “disorders” due to shift work, jet travel, early work and school start times, being an extreme night owl, and the Monday morning blues. She was commissioned by NASA to develop sleep and bright light schedules that the astronauts used to reset their circadian clocks to prepare for the shift work of space shuttle missions. Under her direction her lab has studied bright light treatment of winter depression or seasonal affective disorder and how to reset or phase shift the circadian clock with light and melatonin to reduce jet lag and the circadian misalignment caused by night shift work. She has published more than 100 papers in these areas. Her work has been supported by several federal grants from the National Institutes of Health and the Centers for Disease Control and Prevention (the National Institute for Occupational Safety and Health) over the last 30+ years.
