Research summary
AI-generated

John M. Wo conducts clinical research in gastroenterology, focusing on disorders of how the stomach and gut move food (gastrointestinal motility), particularly gastroparesis, a condition where the stomach empties too slowly. Much of the work evaluates a minimally invasive endoscopic procedure called gastric per-oral endoscopic myotomy (G-POEM) and measurement tools like the functional lumen imaging probe (FLIP), alongside studies on irritable bowel syndrome and connective-tissue-related conditions such as hypermobile Ehlers-Danlos syndrome.

Collaborators per year
Distinct co-authors at Indiana University each year — a rough indication of whether the group around this researcher has been growing or contracting. An estimate from co-authorship, not a roster: collaborators are not necessarily lab members, and recent years can be under-counted while indexing catches up.
