Research in the Carey Laboratory uses hibernating mammals as models for adaptation to extreme changes in physiology and nutrition that occur on a seasonal basis, with a focus on the gastrointestinal tract and liver.  Current studies in the laboratory are examining the symbiotic relationship between mammalian hibernators and their gut microbes.

Our laboratory also uses hibernators as models for identifying natural mechanisms for protection against stress and trauma conditions, including liver cold ischemia (e.g., during organ storage) and warm ischemia/reperfusion injury in gut and liver. These projects are designed to translate basic insights gained from the hibernation phenotype to improvements in human and animal biomedicine.
