With more than 40 years’ experience in the field of basic and applied research on the physiology of the human circadian timing system and its relationship to the sleep-wake cycle, Dr. Czeisler is interested in the physiology of the hypothalamic circadian pacemaker in humans, photic and non-photic synchronizers of the human circadian pacemaker, temporal dynamics in neuroendocrine systems, homeostatic and circadian factors in the regulation of sleep and alertness, and the application of circadian physiology to occupational medicine/health policy, particularly as it relates to the extended duration work shifts and long work weeks.
Charles A. Czeisler, Ph.D., M.D., F.R.C.P., F.A.P.S. is chief of the Division of Sleep and Circadian Disorders, in the Departments of Medicine and Neurology at the Brigham and Women’s Hospital and the Baldino Professor of Sleep Medicine and director of the Division of Sleep Medicine at Harvard Medical School. Dr. Czeisler has more than 40 years of experience in the field of basic and applied research on circadian disorders.
For more than a decade, Dr. Czeisler served as team leader of the Human Performance Factors, Sleep and Chronobiology Team of NASA’s National Space Biomedical Research Institute, which is responsible for developing sleep-wake schedule guidelines and related countermeasures for use by NASA astronauts and mission control personnel during space exploration. He led the sleep experiment in which Senator John Glenn participated during the STS-95 space shuttle mission in 1998. Just this year, he and his colleagues at BWH received the NASA’s Johnsons Space Center Director’s Innovation Award in Houston, for designing a new solid state lighting system that is being installed on the International Space Station this year to improve the sleep of astronauts.
Dr. Czeisler’s research is focused sleep, circadian rhythms, health and performance in humans. Of particular concern to Dr. Czeisler is the epidemic of sleep deficiency in our society with its wide-ranging implications for health, wellness, and the economy.
He is chairman of the Board of Directors of the National Sleep Foundation and Past President of the Sleep Research Society. Dr. Czeisler, who has over 275 publications, was awarded an Honorary Fellowship of the Royal College of Physicians, is an elected member of the Institute of Medicine of the National Academy of Sciences and was elected as an inaugural Fellow of the American Physiological Society. He earned his undergraduate degree from Harvard College and his Ph.D. in neuro- and bio-behavioral sciences and M.D. from Stanford University.
