Jeanne Duffy, PhD

Jeanne is an associate professor of medicine at Harvard Medical School and a sleep researcher at Brigham and Women’s Hospital.

Her research interests include both basic and applied aspects of sleep research and circadian physiology. Her recent work has focused on understanding individual differences in sleep timing, duration, need, and response to acute and chronic sleep loss.

Her group has examined how different aspects of cognitive performance respond to sleep loss, and how those responses differ between groups. Their other work has focused on how features of circadian physiology differ between individuals and groups, and how those circadian rhythm differences contribute to individual differences in sleep.
