Michael J Rosen, MD, MSCI
Stanford University Endowed Professor for Pediatric IBD and Celiac Disease
BioI am a pediatric gastroenterologist and physician scientist, who has been devoted to inflammatory bowel disease (IBD) research since beginning medical training over 20 years ago. I am also Director of the Stanford Center for Pediatric IBD and Celiac Disease. I have expertise crossing mucosal immunology and epithelial biology, formal training and experience in clinical and translational investigation with human biospecimens, and direct insight regarding the important clinical challenges caring for children with complicated IBD. My translational research program focuses on how the immune system regulates epithelial function in chronic intestinal inflammation as it relates to IBD. My clinical research program has focused on optimization of anti-TNF therapy in pediatric IBD, and in particular acute severe ulcerative colitis (ASUC). My laboratory has demonstrated a protective role for IL33, a cytokine that induces type 2 cytokines from T cells an innate lymphoid cells (ILCs), in acute oxazolone colitis through preservation of epithelial goblet cells and barrier function. In line with this finding, we have also shown in a large prospective patient cohort that mucosal expression of type 2 and type 17 immune response genes distinguishes ulcerative colitis (UC) from colon-only Crohn’s disease, and that type 2 gene expression is associated with superior clinical outcome in pediatric UC. We have now developed an organoid-immune cell in vitro culture system to demonstrate the ILC2-dependent mechanism through which IL33 induces goblet cell differentiation in the intestinal epithelium. I led the multicenter study Anti-TNF for Refractory Colitis in Hospitalized Children (ARCH) Study, which aims to establish determinants of anti-TNF response in pediatric ASUC and currently Co-Chair the Crohn's & Colitis Foundations Cohort for Pediatric Translational and Clinical Research in IBD (CAPTURE IBD) and PRO-KIIDS Pediatric IBD clinical research network.
Zachary M. Sellers, MD, PhD
Assistant Professor of Pediatrics (Gastroenterology)
BioI am a pediatric physician-scientist striving to advance cystic fibrosis clinical care and translational research. Clinically, I am focused on gastrointestinal manifestations of cystic fibrosis, developing diagnostic and therapeutic modalities to improve the gastrointestinal and liver health of those with cystic fibrosis. I also specialize in the clinical management of pediatric pancreatitis and am involved with the international INSPPIRE consortium to study pediatric pancreatitis. My research spans the entire spectrum across basic science and translational research to clinical research and trials. In the laboratory, my projects are centered around understanding mechanisms of ion transport in cystic fibrosis tissues and determining how loss of CFTR ion transport leads to pathologic changes in human physiology. We are also very interested in the pathophysiological relationship between pancreatitis and intestinal diseases, such as inflammatory bowel disease. Our laboratory has expertise in epithelial ion transport, with specialized skills in the measurement of bicarbonate transport. We are also part of a Multi-PI collaboration pursuing CFTR gene editing and stem cell engraftment for the treatment of cystic fibrosis. We utilize a combination of immortalized and primary cell culture, organoids, mouse and human tissue, and whole animal in vivo studies.

Current Research and Scholarly InterestsMolecular Regulation of Intestinal Development and Maturation. We study transcriptional mechanisms regulating the spatial and temporal restriction of intestine-specific gene expression during gut development. Our approach is to characterize the function of gene-specific DNA cis elements and interacting nuclear proteins in cell culture and in transgenic animals. The goal is to relate the gene-specific control mechanisms to the broader pathways specifying acquisition of gut phenotypes.

Ann Ming Yeh
Clinical Professor, Pediatrics - Gastroenterology
BioDr. Ann Ming Yeh is a Clinical Professor at Stanford University in Pediatric Gastroenterology and practices at Lucile Packard Children’s Hospital and Stanford Children’s Health. She completed her residency and GI fellowship at Stanford University.
Dr. Yeh’s research interests include diet therapies for inflammatory bowel disease, nutrition, small intestinal bacterial overgrowth, and integrative medicine for pediatric gastroenterology. She has presented her work on fatty liver, inflammatory bowel disease and integrative medicine at national meetings.
She completed a two-year distance learning fellowship through the University of Arizona’s Center for Integrative Medicine where she gained additional expertise in mind-body therapies, botanicals, and nutritional supplements. With skill and compassion, Dr. Yeh treats her patients with a comprehensive, evidence-based, holistic approach. She is also a formally trained and board-certified medical acupuncturist. She is currently the program director for the nation’s premier fellowship for Pediatric Integrative Medicine at Stanford.
Outside of medicine, she enjoys yoga, gardening, hiking, and traveling with her family.
