GI Motility and Neurogastroenterology Unit


The GI Motility and Neurogastroenterology Program is engaged in clinical, translational and device research, especially in the treatment of gastroparesis.  We have ongoing industry-sponsored clinical treatment trials and in investigator-initiated translational studies in GI motility disorders.  Our diverse faculty has various specific research interests, including endoscopic therapy of gastro esophageal reflux, gastroparesis, imaging of brain-gut interaction, cyclic vomiting, genetic contribution of functional bowel disorder, fecal incontinence, and obstructive defecation.  

We have active collaboration with the Department of Cellular and Integrative Physiology at Indiana University in the study of pathophysiology in gastroparesis.  We work closely with the Center for Implantable Devices at Purdue University, School of Biomedical Engineering, in animal and human studies of non-invasive vagal measurement and feedback controlled electrical stimulation for Gastroparesis.  We are collaborating with the Department of Microbiology and Immunology at Indiana University in building a prospective clinical and biologic registry for small bowel microbiome in patients with small intestinal bacterial overgrowth and asymptomatic controls.
