Research Interests

  • Health and safety consequences of sleep and circadian disruption.

  • Influence of sleep and circadian rhythms on human physiology (neuroendocrine, metabolic and immune function) and behavior (sleepiness, memory, learning, mood, cognitive and motor performance) with application to public health and safety.

  • Countermeasures to improve sleep and wakefulness.

Current Research Projects

  • Influence of sleep loss, sleep inertia and circadian disruption on cognitive function.

  • Countermeasures to improve sleep and wakefulness.

  • Physiological and behavioral mechanisms by which insufficient sleep contributes to obesity and diabetes.

  • Physiological mechanisms by which circadian misalignment contributes to metabolic dysregulation.

  • Early morning shift work and sleep disturbance.

  • Resetting the human circadian clock with photic and non-photic stimuli.

Opportunities for Undergraduate Students

  • The requirements for undergraduate students who want a research experience in our Laboratory are:
    • A strong desire to obtain research experiences prior to graduate school, medical school, or advanced study in a health-related field
    • Minimum commitment: One year
    • Minimum hours/week when testing subjects: 10 hours (includes journal club)
    • Minimum experience: No prior experience required
    • Must be willing to work with a team
    • Must be able to work various hours during the day, at night, and on weekends.

  • UROP, independent study, honors thesis, and concurrent BA-MS opportunities are available.
