Expertise Areas:
The Ragland Lab is interested in the process of local adaptation to changing environments, and the mechanisms underlying animal hibernation. Our goal is to understand the mechanisms and targets of natural selection, integrating studies from genomes, to physiology, to whole organism performance. Please refer to the lab website for more information: https://seasonaladaptation.org
