An animal's ability to adapt to short- and long-term changes in temperature is crucial for its survival. Lizards are ectotherms that rely on their environment to regulate body temperature, so they experience a wide range of temperatures. We don't yet know how lizard cells remain viable across extreme temperatures, especially within the brain. We are studying the regulation of brain lipids (i.e., fats) in biological membranes to understand how lizards adapt to and live in extreme environments.
