We are a multi-disciplinary group of investigators focused on establishing the nature of and dynamic changes in human physiological and neurobehavioral responses produced by sleep loss and circadian rhythmicity. Experiments utilizing healthy adult volunteers are conducted in a specially equipped, environmentally isolated Sleep and Chronobiology Laboratory and in the NIH Clinical and Translational Research Center at the Hospital of Pennsylvania (HUP). Basic human translational research within the laboratory characterizes the relationship between the biological basis of sleep need and circadian physiology and their control of waking neurobehavioral functions and health, as reflected in mood, physiological alertness, a range of cognitive functions, quantitative EEG/EOG, endocrine, immune, and inflammatory responses. To this end, we are particularly interested in using a variety of techniques (e.g., genetics, brain imaging, psychopharmacology) to identify biomarkers for differential vulnerability to sleep loss and identify differences under basal conditions. The laboratory also conducts studies of population science on sleep-wake behaviors and noise; develops biomathematical and computational models of sleep and circadian effects on behavior; studies of sleep and performance in operational environments—especially those relevant to human space flight (e.g., on the International Space Station); and develops neurobehavioral technology for use in clinical trials and field studies of occupational fatigue. The laboratory makes its findings known through scientific publications, and it participates in public policy areas involving human health and safety relative to lifestyle factors that impact sleep need. The research is currently funded by grants from NIH, NASA, National Space Biomedical Research Institute, Office of Naval Research, and other private and public agencies.
