Shaoyong Yu, M.D.
Associate Professor of Medicine
Dr. Shaoyong Yu is an Associate Professor of Medicine in the Division of Gastroenterology and Hepatology, Department of Medicine. His studies focus on neurogastroenterology and motility disorders.
Dr. Yu received medical and master’s degrees from Yichang and Tongji Medical Colleges, and a master of public health (MPH) degree from the Johns Hopkins Bloomberg School of Public Health. Before joining the Johns Hopkins faculty, he completed three-year research fellowship training at Johns Hopkins University School of Medicine, focusing on gastrointeastinal motility disorders, plus an additional two-year postdoctoral training in sensory neurobiology at JHU.

Research & Publications
Dr. Yu's research has been focused on sensory afferent neurobiology and never-immune interactions in the GI tract. Specifically, he is interested in studying the cellular and molecular mechanisms underlying vagal afferent activation and mast cell activation-induced sensitization of visceral afferents in the GI tract.
The research projects in my lab focus on sensory neurobiology (vagal afferent function) in the gastrointestinal tract.
A post-doc position is opening to investigate the molecular and cellular mechanisms of visceral sensation and nociception for self-motivated individual who has been trained in electrophysiology (patch clamp and/or extra-cellular recording) and neuron imaging.
