Edward A. Pham
Instructor, Medicine - Gastroenterology & Hepatology
BioMy interest in medicine and research was triggered by my mother’s battle with chronic hepatitis C, which made me realize the transformational power of biomedical research in treating patients. Therefore, my career goal is to become a physician scientist in the field of gastroenterology and hepatology dedicated to translating discoveries in the laboratory into novel medical treatment modalities. My research focus is alterations in phosphoinositides signaling and its pathogenesis in cancers of the hepatobiliary and luminal GI tract with the goal to identify novel targets for therapeutic intervention. I also have a particular interest in understanding the interface between chronic viral infection and cancer through studying how the innate and adaptive immune system are perturbed in chronic viral infections

Dr. Shah treats all gastrointestinal and liver conditions, such as gastroesophageal reflux disease (GERD), colon polyps, hepatitis, inflammatory bowel disease, and irritable bowel syndrome. He has a special interest in the increasingly prevalent fatty liver disease, which allows him to work closely with patients to educate them about symptom management and making lifestyle changes that will improve their health and wellbeing.
After more than two decades of practice, Dr. Shah added training in liver transplant to expand his knowledge of liver disease and offer his patients a “one-stop” resource for truly comprehensive care.
Dr. Shah is a member of the American College of Gastroenterology, American Society of Gastrointestinal Endoscopy, and American Association for the Study of Liver Disease.
Among Dr. Shah’s current research interests is the development of an algorithm assessing the impact of gastrointestinal disease management on readmission rates.
Dr. Shah brings a personalized approach to working with patients and to teaching the next generation of physician scientists the classic skills of careful listening and patient examination. Throughout his career, he has emphasized the fundamental importance of balancing scientific expertise with empathy and compassion.
As a volunteer with the non-profit organization Health Volunteers Overseas, Dr. Shah travels around the world to train physicians about liver disease management and treatment. He is director of the HVO site in Bangalore, India. -
Sundeep Singh
Clinical Associate Professor, Medicine - Gastroenterology & Hepatology
BioAfter living and training throughout the country, I am excited to be part of the Stanford team. As a result of both my personal experiences and training, I am passionate about ensuring that patients receive appropriate diagnostic testing and treatment options in order to improve people's quality of life. In collaboration with my amazing colleagues, I am confident in the high quality and easily accessible care we are able to provide to patients across northern California.
While my interest is most in inflammatory bowel disease, I am also interested in the interaction between mental health, incentives, and emerging therapies in gastroenterology. -
Sidhartha Sinha
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). -
Irene Sonu
Clinical Associate Professor, Medicine - Gastroenterology & Hepatology
BioI am passionate about gut health and strive to provide the best care to my patients. I specialize in complex motility disorders of the gastrointestinal tract. My areas of clinical expertise include achalasia, dysphagia, eosinophilic esophagitis, gastroesophageal reflux disease, gastroparesis, functional dyspepsia, irritable bowel syndrome, and pelvic floor dysfunction. I also see patients in need of fecal microbiota transplant for recurrent C. difficile infection.

Natalie Torok
Professor of Medicine (Gastroenterology and Hepatology)
Current Research and Scholarly InterestsOur lab is focused on exploring the role of matrix remodeling in disease progression in metabolic dysfunction steatohepatitis (MASH)-related hepatocellular carcinoma and primary sclerosing cholangitis. Our goal is to uncover how biomechanical characteristics of the ECM affect mechano-sensation, and how these pathways could ultimately be targeted. We are also interested in aging and its effects on metabolic pathways in MASH and HCC.
