What We Do

The Center is home to ground-breaking discoveries in the mechanisms underlying and health impact of sleep and circadian rhythms. The Center creates an environment that fosters collaborations between reserachers in different disciplines who have mutual research interests in the study of circadian rhythms and sleep. Founded in 1995 as the Center for Circadian Biology and Medicine, the Center was renamed in 2000 in recognition of the increasing emphasis on sleep research by Center Members.




The Center for Sleep & Circadian Biology (CSCB) is a University Research Center that integrates basic, clinical, and translational research on sleep and circadian rhythms into a unified program at Northwestern University.

Featured Story

Dr. Phyllis Zee honored with Sleep Research Society’s 2020 Distinguished Scientist Award

Dr. Zee has made numerous invaluable contributions to the growth of the sleep and circadian field. For example, in 2014 she established, and continues to lead, the first circadian medicine clinic in the USA. This clinic has the potential to help raise the profile and accessibility of circadian medicine, a long-neglected aspect of the field.  Dr. Zee was chair of the NIH National Sleep Disorders Research Advisory Board and served as a member of the NIH National Heart, Lung and Blood Advisory Council.  She is also a past president of the Sleep Research Society, past president of the Sleep Research Society Foundation, and is the current president elect of the World Sleep Society.  She has authored 266 publications that have been cited nearly 7,000 times.   She is a rare example of a physician scientist who can translate the latest ideas from basic research into something meaningful for her patients in the clinic.
