Zee, PhD is Professor of Neurology, Neurobiology, and Physiology, and Director of the Sleep Disorders Center and the Sleep Medicine Fellowship program, at Northwestern University Feinberg School of Medicine, where she is also the associate director of the Center for Sleep and Circadian Biology.

Dr. Zee's research has focused on the effects of age on sleep and circadian rhythms, genetic regulation of circadian sleep disorders, and behavioral interventions to improve sleep and performance. Current NIH-funded research projects include studies to examine the ability of exercise to improve sleep and health in older people with insomnia, phenotypic characterization and genetic analysis of circadian rhythm sleep disorders, relationship between sleep, metabolic and cardiovascular risk and the effects of age on the neural response to sleep loss.

She has been active in several committees and professional organizations. She is the recipient of a Sleep Academic Award from the National Institutes of Health. In addition to patient care, research, and teaching, Dr. Zee serves on numerous national scientific review panels and is on the Board of Directors of the National Sleep Foundation and Chair of the Sleep Disorders Research Advisory Board at the NIH.
