Research Interests:
Adaptation to night work; chronotypes (morning and evening types) and delayed timing of the sleep-wake schedule; effects of light exposure on circadian rhythms, sleep and vigilance; circadian rhythms and sleep-wake cycle in various medical conditions (traumatic brain injury, COPD).

Field and laboratory studies; ambulatory measures of light exposure and rest-activity cycle (actigraphy); measure of non-visual sensitivity to light and of melatonin production; controlled light exposure.
