Jon-Paul Pepper, MD
Associate Professor of Otolaryngology - Head & Neck Surgery (OHNS)
On Leave from 2026-07-27 To 2026-08-31Current Research and Scholarly InterestsFacial paralysis is a debilitating condition that affects thousands of people. Despite excellent surgical technique, we are currently limited by the regenerative capacity of the body. The mission of our research is to identify new treatments that improve current facial paralysis treatments. We do this by exploring the regenerative cues that the body uses to restore tissue after nerve injury, in particular through pathways of neurogenesis and nerve repair in small mammals.
