Biography

Tracey’s research focus is in the role of sleep and the circadian system on waking function. She studies the impact of sleep loss and circadian misalignment on sleepiness and neurobehavioural performance, phenotyping and treatment of circadian rhythm sleep disorders, impairments associated with shift work, and numerous applications of lighting to enhance alertness.

She is currently conducting large-scale field assessments of sleep, circadian phase, cognitive functioning and psychological health in expeditioners over-wintering in Antarctica.
