Andrea Shin, MD, is an Assistant Professor at Indiana University in Indianapolis, Indiana within the Division of Gastroenterology and Hepatology with a special interest in disorders of gut-brain interaction (DGBI) and gastrointestinal motility. As a clinical gastroenterologist at Indiana University, Dr. Shin trains undergraduate students, medical students, residents, and fellows. She specializes in the care of patients with DGBI and gastrointestinal motility disorders. She is committed to providing individualized care that emphasizes the multidimensional nature of DGBI and motility disorders.

Her research focus relates to her clinical expertise and focuses on developing novel diagnostic and therapeutic approaches to treating disorders such as irritable bowel syndrome (IBS), functional diarrhea, chronic diarrhea, and anorectal disorders. During her research fellowship under the mentorship of Dr. Michael Camilleri, she conducted clinical trials in patients with IBS, functional constipation, and gastroparesis including a prospective study examining fecal bile acid associations with stool characteristics and colonic transit. This work led to the development of new clinical tests; fecal bile acids are now recognized as an actionable diagnostic biomarker in patients with chronic bowel dysfunction. Her current and specific research interests include study of the role of the microbiome, metabolome, diet and psychological distress in IBS, chronic constipation and functional diarrhea. She is a prior recipient of an institutional career-development award (KL2) and a current recipient of a K23 career development award through the National Institutes of health. She is a Rome V committe member of the Functional Bowel Disorders Committee, served as a lead physician investigator for the AGA’s IBS in American Campaign, and is a former member of the AGA Clinical Practice Update Committee. She co-authored several clinical practice update documents including an update on the use of surgical interventions and device-aided therapies for the treatment of anorectal disorders and a separate update on functional gastrointestinal symptoms in patients with inflammatory bowel disease. She leads the Indiana University Microbiome Research Group, a multidisciplinary community with overlapping interests in microbiome science. She has co-authored over 50 peer-reviewed publications and serves as an editorial board member for several journals including Alimentary, Pharmacology, & Therapeutics and BMC Medicine. She served as the 2019 Indianapolis leader for the GI and Nutrition Course for second year medical students.

Dr. Shin received her medical degree from Indiana University School of Medicine and completed her internal medicine residency at Indiana University School of Medicine. She then earned a Master’s degree in clinical and translational research while training as a research fellow at Mayo Clinic in Rochester, Minnesota, followed by completion of a clinical fellowship in gastroenterology and hepatology at Indiana University. She is an active member of several organizations including the American Gastroenterological Association (AGA), American College of Gastroenterology (ACG) and American Neurogastroenterology and Motility Society (ANMS).
