Biography

Stephen G. Waxman, MD, PhD

Stephen Waxman is the Bridget Flaherty Professor of Neurology, Neurobiology, and Pharmacology at Yale University, and served as Chairman of Neurology at Yale from 1986 until 2009. He founded the Neuroscience & Regeneration Research Center at Yale in 1988 and is its Director. Prior to moving to Yale, he worked at Harvard, MIT, and Stanford. He is a Visiting Professor at University College London.

Dr. Waxman received his BA from Harvard, and his MD and PhD degrees from Albert Einstein College of Medicine. His research uses tools from the “molecular revolution” to find new therapies that will promote recovery of function after injury to the brain, spinal cord, and peripheral nerves.

Dr. Waxman’s first paper in Nature was published in 1970. His research has defined the ion channel architecture of nerve fibers, and demonstrated its importance for axonal conduction (Science, 1985). He demonstrated increased expression of sodium channels in demyelinated axons (Science, 1982), identified the channel isoforms responsible for this remarkable neuronal plasticity which supports remission in multiple sclerosis (PNAS, 2004), and delineated the roles of sodium channels in axonal degeneration (PNAS, 1993). He has made pivotal discoveries that explain pain after nerve injury. In translational leaps from laboratory to humans, he carried out molecule-to-man studies combining molecular genetics, molecular biology, and biophysics to demonstrate the contribution of ion channels to human pain (Trends in Molec.Med, 2005; PNAS, 2006). He led an international coalition that identified sodium channel mutations as causes of peripheral neuropathy (PNAS, 2012). He has used atomic-level modeling to advance pharmacogenomics, first in the laboratory (Nature Comm., 2012), and then in the clinic in a paper (JAMA Neurology, 2016) that was accompanied by an editorial stating “there are still relatively few examples in medicine where molecular reasoning has been rewarded with a comparable degree of success”. An entirely new class of medications for neuropathic pain, based largely on his work, is currently in Phase II clinical trials.

Dr. Waxman has published more than 700 scientific papers. His H-index is 109 and his papers have been cited more than 40,000 times. He has edited nine books, and is the author of Spinal Cord Compression and of Clinical Neuroanatomy (translated into eight languages). He has served on the editorial boards of many journals including Annals of Neurology, Brain, Journal of Physiology, Trends in Neurosciences, Nature Reviews Neurology, and Trends in Molecular Medicine, and is Editor-in-Chief of The Neuroscientist and Neuroscience Letters. He has trained more than 200 academic neurologists and neuroscientists who lead research teams around the world.

A member of the National Academy of Medicine, Dr. Waxman has served on many advisory councils, including the Board of Scientific Counselors of NINDS. His many honors include the Tuve Award (NIH), the Distinguished Alumnus Award (Albert Einstein College of Medicine), the Dystel Prize and Wartenberg Award (American Academy of Neurology), the Middleton Award and the Magnuson Award from the Veterans Administration, and the Soriano Award from the American Neurological Association. He was honored in Great Britain with The Physiological Society’s Annual Prize, an accolade he shares with Nobel Prize laureates Andrew Huxley, John Eccles, and Alan Hodgkin. In 2018, Waxman received the Julius Axelrod Prize from the Society for Neuroscience.

Research

Overview

My laboratory focuses on functional recovery in diseases of the brain and spinal cord. In particular, we use a spectrum of methods including molecular biology and genetics, cell biology, electrophysiology, computer simulations, molecular modeling etc. to understand how the nervous system responds to injury, and how we can induce functional recovery. Approaching these issues from a molecule- and mechanism-driven standpoint, we have a special interest in spinal cord injury, multiple sclerosis, and neuropathic pain. Our early studies demonstrated the molecular basis for remissions in MS. We have a major interest in the role of ion channels in diseases of the brain and spinal cord. We have demonstrated, for example, that following injury to their axons, spinal sensory neurons turn off some sodium channel genes, while turning others on. This results in the production of different types of sodium channels (with different kinetics and voltage-dependencies) in these neurons, causing them to become hyperexcitability and thereby contributing to neuropathic pain.

We are also interested in hereditary neuropathic pain and have delineated, for the first time, the molecular basis for a hereditary pain syndrome (inherited erythromelalgia; OMIM #133020;#603415). We have identified mutations in ion channel genes that cause painful peripheral neuropathy, and are moving toward pharmacogenomically-guided pain pharmacotherapy. We have also used molecular genetics and stem-cell derived models to identify pain resilience genes.

We are using state-of-the art molecular imaging to determine how nerve cell build their excitable membranes, molecule by molecule. My laboratory is also examining the role of abnormal sodium channel expression in spinal cord injury (SCI) and multiple sclerosis (MS). Specific projects focus on molecular mechanisms of recovery of conduction along demyelinated axons, and on molecular substrates of axonal degeneration. We are also studying neuroprotection, and have demonstrated that it is possible to pharmacologically protect axons, so they don't degenerate in SCI and MS.
