Research Areas

Broad research interest is the circadian timing system and testing methods to correct misalignment between sleep and circadian timing. Research focuses on understanding and manipulating the circadian timing system during adolescence, a time when circadian misalignment is at its peak.

Biography

Stephanie Crowley, PhD studies sleep and circadian timing in humans. Her research program focuses on understanding basic circadian physiology and sleep behavior across adolescence, as well as developing and testing strategies to correct circadian misalignment (the mismatch between sleep and the circadian system) that is often experienced by teens in middle and high school. 

A hallmark of adolescence is a significant change in sleep behavior, particularly the timing of sleep and wake. Sleep regulatory systems (homeostatic and circadian systems) change with pubertal maturation, and these changes appear to be permissive of late bedtimes and favor evening alertness as adolescents age. School start times and thus school wake times for adolescents, however, become earlier with age. Late bedtimes and early school wake times restrict sleep during the school week to less than recommended, and sleep of many adolescents is mistimed on school nights (i.e., they are waking too early according to their 24-h circadian clock). Crowley’s previous and ongoing NIH-funded studies aim to fill a gap in our understanding of the basic mechanisms driving the adolescent sleep/wake behavior change and test methods to reduce the mismatch between internal circadian rhythms and external social rhythms in these youngsters.
