Dr. Gosain directs pediatric surgery research at the Children’s Foundation Research Institute of the Le Bonheur Children’s Hospital. His NIH-funded laboratory research focuses on the development of the enteric nervous system and gastrointestinal mucosal immune system. The long-term goal of his research is to gain an understanding of the interactions between the enteric nervous system and gastrointestinal immune system in both development and disease to permit the generation of novel neuro-immunomodulatory therapies that may potentially target a broad range of congenital and acquired pediatric gastrointestinal tract diseases (hirschsprung disease, necrotizing enterocolitis, intestinal atresia, motility disorders, inflammatory bowel disease, etc.).
