About Karyn Esser

My lab has pioneered research on the role of circadian rhythms and the circadian clock mechanism in skeletal muscle homeostasis and systemic health. We have defined that the muscle clock is necessary for maintenance of muscle function (i.e. strength) and metabolic flexibility with a key role regulating glucose metabolism. We have shown that the phase settings of the muscle clock are uniquely sensitive to the time of muscle contractions/exercise and occur in the absence of changes in the central clock. These discoveries have led to the potential for exercise timing as a therapeutic strategy to support muscle clock function in chronic diseases.

Our current research directions include questions about the role of the muscle clock in muscle adaptations to exercise and the mechanisms of muscle clock changes with aging and how that contributes to known age-associated changes in muscle strength and metabolism. We also have a number of ongoing collaborations working with both pre-clinical and clinical researchers to better understand the fundamental role of the circadian clock in muscle and human health.
