Phyllis Zee, MD, PhDThe Center for Circadian and Sleep Medicine is essentially interested in the interaction of sleep and circadian clock systems on biology. A variety of behavioral and pharmacological approaches are used to restore the responsiveness of, and realign, the system of sleep and circadian rhythms. We are trying to determine whether several factors, including exposure to scheduled bright light, certain medication regimens and/or structured activity cycles will correct some of the age- and pathology-related changes in the human circadian system and result in the improvement of performance, mood, daytime alertness, and sleep. These findings can be used to improve understanding of and treatment for a broad spectrum of disease and disorders.
