Dr. Czeisler was a panelist for the Forum’s discussions on Fighting the Clock: How America’s Sleep Deficit is Damaging Longterm Health and Asleep at the Wheel.
Dr. Charles Czeisler is the Baldino Professor of Sleep Medicine in the Department of Neurobiology at Harvard Medical School, where he is also the Director of the Division of Sleep Medicine. Dr. Czeisler is a Senior Physician and Chief of the Division of Sleep and Circadian Disorders in the Departments of Medicine and Neurology at Brigham and Women’s Hospital.
His laboratory research is focused on understanding the neurobiology of the human circadian pacemaker and its interaction with the sleep homeostat, and on applying that knowledge to clinical medicine and occupational health. His laboratory is now investigating how the timing, duration, intensity and wavelength of light affects circadian resetting capacity. Current research is aimed at functional determination of the photoreceptor(s) responsible for circadian vision in humans, and how circadian and homeostatic processes interact to regulate sleep and neurobiological function during wakefulness. Other ongoing research in the lab includes examining novel wakefulness- and sleep-promoting countermeasures, the effect of exercise on the circadian pacemaker, fMRI of the sleep deprived brain, the influence of aging on sleep and circadian rhythms, the influence of chronic sleep restriction on human performance, and the influence of space flight on sleep and circadian rhythms.
