We study neuroscience at the intersections of:
sleep, metabolism, stress, and sedation

Examples of questions that drive our science:
- How does the brain link energy expenditure, body temperature regulation, and sleep?
- How does stress lead to disruptions in sleep?
- What neural pathways link sleep disturbances to metabolic changes?
- How are the circuits regulating sleep involved in generating aspects of anesthetic states?
- How does sleep disruptions impact our ability to cope with stressors?
- How does the brain link energy expenditure, body temperature regulation, and sleep?
