Northwestern University supports multidisciplinary research examining the relationships between sleep, circadian rhythms, brain function, metabolism, and human health. Research interests include circadian biology, sleep timing, light exposure, mood disorders, neurodegenerative disease, and the health consequences of circadian disruption. Through laboratory, clinical, and translational research, investigators study how biological rhythms influence physical and mental wellbeing. The program contributes to the development of evidence-based approaches to improving sleep health, circadian alignment, and the prevention and management of chronic disease.
