John Hollier, MD is an assistant professor at Baylor College of Medicine in Houston, Texas. He received a Doctor of Medicine degree from the University of Texas Southwestern Medical School in 2008 and is a practicing pediatric gastroenterologist at Texas Children’s Hospital. As a physician-scientist, he has obtained additional training in health service research, clinical research, and implementation science to investigate how to improve optimal care delivery for children with disorders of gut-brain interaction (DGBI) within healthcare systems. DGBI, formerly called functional gastrointestinal disorders, are defined as chronic abdominal pain conditions that cannot be attributed to abnormal biomedical testing or imaging, and irritable bowel syndrome is one of the most common disorders. Those with DGBI have associated increased psychosocial distress like anxiety and depression and poorer health-related quality of life than their healthy peers. My research explores the association between psychosocial distress and symptom severity, the economic burden of these disorders, and the development of electronic technologies to remotely deliver psychosocial therapies to affected children.
