Stephen Walker, PhD
Stephen Walker, PhD is a Professor of Regenerative Medicine at the Wake Forest Institute for Regenerative Medicine (WFIRM) in the Wake Forest School of Medicine, Winston- Salem, NC. He received his PhD in Genetics and Developmental Biology at West Virginia University and was a Post-Doctoral Fellow in the Molecular Genetics Program at Wake Forest Baptist Health prior to joining the Department of Pediatrics faculty in the Section on Medical Genetics.
Dr. Walker’s group is focused on the application of integrated multi-omics approaches, using patient biospecimens, to understand the molecular basis for chronic gastrointestinal symptoms in children with an autism spectrum disorder diagnosis, and to understand how chronic GI problems early in childhood may impact neurodevelopment. The objective of this work is to identify clinically relevant biological markers that can be used for diagnosis and/or as therapeutic targets to the benefit of this vulnerable and underserved population.
