RESEARCH

I have a broad interest in how biological clocks are synchronized in organisms, and how these affect physiology and behavior. I have a particular interest in how shift work increases the risk for disease. Current efforts employ behavioral and physiological approaches in order to investigate the following:

1)    The effects of clock synchrony on cardiometabolic health.
2)    How the circadian clock governs sleep apnea severity in humans.
3)    Temporal patterns of sleep apnea as predictors of mortality.
4)    How the time of day of a traumatic brain injury changes its severity and prognosis.
