Research Research overview Wallerian Degeneration Alzheimer's Disease Parkinson's Disease Peripheral Neuropathies Nerve Repair Recurrent Laryngeal Neuropathy Traumatic Brain Injury Research Overview At the core of our research is Wallerian degeneration. We discovered gene mutations that prevent or activate axon loss through this pathway and apply the knowledge, skills and resources developed in these studies to axon and synapse loss in disease.
