Research Summary

To survive extreme environments, many animals have evolved the ability to profoundly decrease metabolic rate and body temperature and enter states of dormancy, such as torpor and hibernation. Our laboratory studies the mysteries of how animals and their cells initiate, regulate, and survive these adaptations. Specifically, we focus on investigating: 1) how the brain regulates torpor and hibernation, 2) how cells adapt to these states, and 3) whether inducing these states can slow down tissue damage, disease progression, and even aging. Our long-term goal is to explore potential applications of inducing similar states of “suspended animation” in humans.
