John Rosen is a Professor in the Department of Pediatrics Gastroenterology at the University of Arkansas for Medical Sciences (UAMS) and serves as the Director of Pediatric Neurogastroenterology and Motility. His clinical and research focus centers on pediatric gastrointestinal motility disorders, functional abdominal pain, neurogastroenterology, and innovative therapeutic interventions such as botulinum toxin applications and telehealth integration.

Dr. Rosen's research spans:

• Functional gastrointestinal disorders (FGIDs) including constipation, gastroparesis, and irritable bowel syndrome
• Neuroimmune mechanisms of chronic pelvic/abdominal pain
• Telehealth implementation in pediatric gastroenterology
• Artificial intelligence applications in clinical practice
• Surgical innovations for motility management

His recent publications (2020-2025) demonstrate strong emphasis on:

• Developing clinical guidelines through NASPGHAN
• Novel pain modulation techniques (e.g., open-label placebo)
• Microbiome-pain interactions
• Digital health technologies (AI, telehealth)
• Innovative drug delivery systems

Trends show increasing focus on technology-driven solutions and multicenter collaborative research.
