Research Interests

I use mathematical models of physiology to gain insights into sleep and circadian rhythms in humans and other species. Current research interests include:
1) Understanding how the sleep-regulatory circuits in the mammalian brain give rise to observed sleep behaviors, including differences in sleep duration and timing between individuals and between species.
2) Understanding how interactions with our environment and social interactions affect sleep and circadian timing.
3) Understanding the effects of chronically insufficient sleep on sleep physiology and cognitive performance.
4) Modeling the effects of stimuli and pharmaceuticals on sleep and circadian rhythms.
5) Predicting how individuals will perform under different schedules and optimizing individuals’ performances.
