Li, Dan

Dan Li, MD, is a senior physician and gastroenterologist with The Permanente Medical Group. He is also a clinical investigator with the Delivery Science & Applied Research Program at Kaiser Permanente Northern California Division of Research.

Dr. Li’s research focuses on the screening and prevention of gastrointestinal cancers, with a special emphasis on gastric cancer and colorectal cancer. As a clinician scientist, Dr. Li has extensive experience in cancer outcome research, with multiple publications in top-tier medical journals such as Annals of Internal Medicine, Gastroenterology, and Gut. Many of his research projects utilize Kaiser Permanente’s large and well-maintained electronic databases which include health information of 4.6 million individuals in Northern California.

Dr. Li’s current research involves several areas of gastrointestinal cancer prevention, including: 1) optimizing gastric cancer prevention through risk stratification and surveillance in patients with gastric premalignant conditions; 2) reducing gastric cancer risk through targeted H. pylori screening and eradication; 3) optimizing risk stratification for colorectal cancer in patients with serrated colonic lesions; and 4) optimizing screening and management of Lynch syndrome. Dr. Li currently serves as a guideline panel member of both American Gastroenterological Association and American College of Gastroenterology on the diagnosis and management of gastric premalignant conditions. Dr. Li is also the Medical Director of the Lynch syndrome screening program, Regional Quality Lead in Gastroenterology, and a member of the Precision Medicine Steering Committee at Kaiser Permanente Northern California.

Dr. Li completed his undergraduate studies at Peking University and received his MD at the Peking Union Medical College in Beijing, China. He finished his residency training in Internal Medicine at the Brigham and Women’s Hospital of Harvard Medical School, and his fellowship training in Gastroenterology at the University of California, San Francisco.
