My team studies sleep neurobiology and occupational health. We examine the physical and psychological consequences of work schedules that restrict the timing of sleep. We aim to make new discoveries about circadian rhythms, heart rate variability, brain mechanisms, and the microbiome, ultimately leading to the development of novel health-promoting therapies.
Importantly, people who work irregular and unpredictable schedules have an elevated risk for inadequate sleep (e.g., healthcare and transportation sectors). Chronically inadequate sleep impairs cardiovascular health, which can eventually lead to diseases and fatalities (e.g., stroke, heart failure). Sleep deprivation increases the risk for errors and accidents in the workplace. To address these serious public health and safety problems, my colleagues and I conduct experiments to understand how poor sleep evokes high blood pressure and impairs health and safety.
