    BioDr. John Clarke recently joined the Gastroenterology & Hepatology Division at Stanford University as Director of the Esophageal Program. He previously spent 17 years in Baltimore, including 9 years on the faculty at Johns Hopkins University where he was an Associate Professor and at various times Director of Esophageal Motility, Director of Gastrointestinal Motility, Clinical Director of the Johns Hopkins Center for Neurogastroenterology, and Clinical Director of the Gastroenterology & Hepatology Division at Johns Hopkins Bayview Medical Center.

    His career has combined research, education and clinical care. His clinical areas of expertise include achalasia, dysphagia, eosinophilic esophagitis, esophageal dysmotility, gastroesophageal reflux disease, gastroparesis, GI-manifestations of scleroderma and GI dysmotility. While at Johns Hopkins University, he was inducted into The Miller-Coulson Academy for Clinical Excellence, an institutional honor society for master clinicians at the time limited to 50 members across the entire university.

    From an education standpoint, he has lectured in over a dozen countries, authored over 25 textbook chapters and serves on the educational affairs committee of the American College of Gastroenterology. He has also won several major teaching awards, including The Johns Hopkins University Alumni Association Award for Excellence in Teaching, given to one faculty member per year in the entire School of Medicine.

    Shoa L. Clarke, MD, PhD

    Assistant Professor of Medicine (Stanford Prevention Research Center) and of Pediatrics (Cardiology)

    BioDr. Clarke is a preventive cardiologist and a physician-scientist focused on disease prevention. He earned his undergraduate degree in human biology from the Division of Nutritional Sciences at Cornell University before obtaining his MD and PhD (genetics) from Stanford University School of Medicine. He has completed clinical training in internal medicine (Brigham & Women’s Hospital), pediatrics (Boston Children’s Hospital), and cardiovascular medicine (Stanford Hospital), and he is board certified in all three specialties. His research is focused on 1) understanding complex disease genetics in diverse populations, 2) integrating monogenic and polygenic risk with clinical risk, 3) large-scale phenotyping using the electronic health record and medical images. His clinical practice focuses on identifying risk factors for cardiovascular disease with the goal of promoting health and longevity through evidence-based personalized treatment. He is interested in developing family-centric approaches for the treatment of adults and children carrying genetic risk for disease.

    In 2020, Dr. Clarke was the recipient of the Department of Psychiatry and Behavioral Science's Clinical Innovation and Service Award. Dr. Clarke was also awarded funding from the Professional Leadership Development Awards Program for the 20-21 academic year, which supports the career development of department faculty who exhibit particular promise in advancing into leadership roles in academic medicine. Dr. Clarke has been funded by a grant from the Department of Psychiatry and Behavioral Sciences and the Maternal and Child Health Research Institute to study the safety and feasibility of providing exposure-based trauma treatment to suicidal teens in stage I DBT.

    Dr. Clarke also maintains a small private practice, where she provides consultation, parent coaching, and individual therapy for adolescents and adults using DBT, FBT, exposure and response prevention, ACT, compassion-focused, and other CBT and evidence-based approaches.
