Research

Gastroenterology fellows participate in ongoing independent research and become proficient in the critical assessment of the medical literature pertinent to gastroenterology and hepatology. To advance fellow’s professional development and research experience, dedicated research faculty members provide additional support and expertise. Current faculty research interests include interventional endoscopy, endoscopic quality, hepatology, motility, fecal microbiota transplant, and inflammatory bowel disease. Recent research studies have included fecal microbial transplantation protocol implementation, clinical trials for gastroparesis, incidence of colonic diverticulosis and diverticulitis in patients with adult polycystic kidney disease, CT angiography for GI bleed, and methods for improved adenoma detection rates.

Each fellow is expected to have at least one peer‐reviewed publication during the three-year fellowship. Time is protected for pursuit of meaningful research and advancement of best practices. Additional training and statistical support is also available through the department of research and innovation at St. Luke’s University Hospital.

St. Luke’s University hospital is in the process of initiating a peer-reviewed clinical research journal.
