Rewriting the rules of recovery after injury.
We investigate the neuro-immune mechanisms of nature's best healers to unlock the secrets of scar-free regeneration.
About
In the Varholick Lab, we believe that to understand tissue regeneration we must look at the whole animal. We don't just study cells in a dish; we study how an animal's behavior, brain, and environment interact to drive and assist with healing.
We are a team of curious problem-solvers. Whether you are an undergraduate looking for your first research experience or a collaborator with a new perspective, we believe that good science is a team sport.

The Behavioral Biology of Super-Healers
Before we can mimic regeneration, we must understand the animals that master it. We explore the ethology and unique physiology of species like the Spiny Mouse and Salamander—investigating everything from their distinct glands and memory to their sensory communication.
Explore our models →Behavior as a Driver of Repair
Behaviors drive evolution and development, why not repair? We investigate how sensation, movement, and critical periods of plasticity actively drive the restoration of tissue. We ask: How do the brain and body "react" to the wound to assist with perfect healing?

Our ultimate goal is translation. By decoding the input signals that enable and assist with regeneration in animals, we aim to develop bio-behavioral therapies that work alongside regenerative therapies to minimize scarring and maximize behavioral recovery.
