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.
Eric Sibley, M.D., Ph.D.
Professor of Pediatrics (Gastroenterology)
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.
Assistant Professor of Medicine (Gastroenterology and Hepatology)
Current Research and Scholarly InterestsThere are two primary and overlapping emphases of my research, both of which are driven and united by needs-based innovation and translational potential:
(1) Understanding the microenvironment of the inflamed versus normal gut in order to identify better therapeutic targets for people with immune-¬mediated GI disorders. Here, our investigations include understanding the influence and interactions of pharmacologic and dietary interventions on gut microbiome/metabolomic changes and the host immune response. In the context of providing patients with new understanding and solutions for their disease, I have led and advised on the design of both pilot and large clinical trials (including new FDA approved therapies) for anti-inflammatory therapies;
(2) Applying novel approaches and technologies (including natural language processing, computer vision, and reinforcement learning) to identify and address unmet clinical needs. In this area we have ongoing and published efforts in my lab to validate and develop solutions to pressing clinical needs. We have developed/led new drug delivery technologies with a multidisciplinary team that have shown strong potential in ongoing human IBD clinical trials. My lab has utilized both supervised and unsupervised approaches to analyze social media discourse and unstructured data sets for identifying patient needs that are rarely addressed in clinical settings. We have gained insights into patient perceptions around preventative health interventions, such as health screening and diet, including the dearth of evidence-based dietary recommendations to treat IBD (despite strong patient desire for solutions in this domain).
Michael Snyder, Ph.D.
Stanford W. Ascherman Professor of Genetics
Current Research and Scholarly InterestsOur laboratory use different omics approaches to study a) regulatory networks, b) intra- and inter-species variation which differs primarily at the level of regulatory information c) human health and disease. For the later we have established integrated Personal Omics Profiling (iPOP), an analysis that combines longitudinal analyses of genomic, transcriptomic, proteomic, metabolomic, DNA methylation, microbiome and autoantibody profiles to monitor healthy and disease states
Justin L. Sonnenburg
Alex and Susie Algard Endowed Professor
Current Research and Scholarly InterestsThe goals of the Sonnenburg Lab research program are to (i) elucidate the basic mechanisms that underlie dynamics within the gut microbiota and (ii) devise and implement strategies to prevent and treat disease in humans via the gut microbiota. We investigate the principles that govern gut microbial community function and interaction with the host using a broad range of experimental approaches including studies of microbiomes in diverse human cohorts.
Clinical Professor, Medicine - Gastroenterology & Hepatology
BioDr. Sarah Streett is a Clinical Professor of Medicine, the Director of Inflammatory Bowel Disease Education at Stanford, and she is passionate about taking care of people with IBD. She is a national expert in treating complex IBD and initiated a multi-disciplinary approach to care with colorectal surgery, pediatrics, and nutrition. In 2018 she received the Champion of Hope Award from the Crohn’s and Colitis Foundation and serves on their National Scientific Advisory Committee. Her interests focus on fertility and pregnancy in people with IBD, developing precision approaches to IBD therapy, and the role that the microbiome and diet play in its pathogenesis. She is a primary investigator of the Stanford IBD Registry and has research projects focused on optimizing clinical outcomes in IBD, the role of the microbiota and diet in IBD and pregnancy, and applying new technologies to individualizing therapy for IBD. She is also the primary investigator on multiple industry-sponsored IBD trials.
Teaching is a top priority for Dr. Streett who feels that mentoring fellows in the development of their careers is a privilege. She has held many national leadership roles in the American Gastroenterological Association, where she has been Chair of the Practice Management and Economics Committee, and currently serves on the Government Affairs Committee. She also an appointed member of the Gastrointestinal Drug Advisory Committee at the FDA. She has represented the interests of gastroenterologists and their patients on Capitol Hill numerous times. Dr. Streett believes strongly in a collaborative approach to give patients personalized care based on the latest therapies for the treatment of IBD and is committed to mentoring the next generation of experts in the field.
Ali Bin Syed
Clinical Assistant Professor, Radiology - Pediatric Radiology
BioDr. Syed is a member of the divisions of Pediatric Radiology and Body MRI and serves as the Director of MRI for Stanford Medicine Children's Health. His clinical interests include MR imaging of pediatric and adult hepatobiliary disorders, inflammatory bowel disease, gynecologic pathology, and congenital heart disease. He is also an active researcher, collaborating with fellow engineers and scientists at Stanford to translate technical innovations in MRI into improved patient care. His recent work focuses on translation of machine learning techniques for rapid, robust MRI in children and adults.
