Walker was recruited to the University of Utah in 1976, where he established the Division of Pediatric Neurosurgery, becoming Division Chief in 1978, a position he held for 28 years. During this time, he built the service into one of the busiest in North America, now performing over 1000 operative procedures annually and consisting of four full-time pediatric neurosurgeons. Walker has a distinguished career in neurosurgery and has been invited as a Visiting Professor to numerous centers around the world. He has been instrumental in the development of pediatric neurosurgery as a subspecialty. Walker has been the President of the Joint Section of Pediatric Neurosurgery of the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the President of the American Society of Pediatric Neurosurgery (ASPN), and the President of the International Society of Pediatric Neurosurgery (ISPN). He has made seminal academic contributions in many areas of pediatric neurosurgery, especially in hydrocephalus. Walker has served on the editorial board of multiple journals and has just completed his term as Chairman of the Editorial Board of the Journal of Neurosurgery: Pediatrics. He recently served as Chairman of the Accreditation Council for Pediatric Neurosurgery Fellowships.
Walker’s passion for the Hydrocephalus Association comes from the many children with hydrocephalus he has treated during his career and the often heartbreaking nature of the condition. He has played an integral role in the Hydrocephalus Association’s establishment of its hydrocephalus research program, which he credits for re-energizing him. He believes the Association is headed in the right direction to make significant improvements in the treatment and long term management of hydrocephalus, with a goal to cure the condition. Walker serves on the board so that he is able to provide input that will lead to improvements in care, and states “I love this opportunity!”
