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.

Reproducible changes in the gut microbiome suggest a shift in microbial and host metabolism during spaceflight

Space environment imposes a range of challenges to mammalian physiology and the gut microbiota, and interactions between the two are thought to be important in mammalian health in space. While previous findings have demonstrated a change in the gut microbial community structure during spaceflight, specific environmental factors that alter the gut microbiome and the functional relevance of the microbiome changes during spaceflight remain elusive.
