My research focuses on the effects of sleep and sleep
deprivation on neurobehavioral functions. I conduct experiments with
human volunteers staying in the laboratory for multiple days (up to 2
weeks). These studies provide insight into the interactions of time
awake versus time asleep (i.e., sleep homeostasis), circadian rhythms,
and other regulatory mechanisms affecting waking neurobehavioral
performance. I am particularly interested in inter-individual
differences in sleep architecture and in the cognitive responses to
sleep loss, having demonstrated that these inter-individual differences
constitute neurobiological traits. In addition, I am engaged in
mathematical and statistical modeling of the temporal changes in
performance across extended periods of wakefulness. Many students are
actively involved in conducting the experiments and analyzing the data
underlying this research.
