The Tabibian Laboratory takes a collaborative and multi-pronged approach to research centered around the following overarching and interwoven areas of focus:
- Novel techniques, applications, and advances in gastrointestinal and pancreatobiliary endoscopy
- Quality improvement, health disparities, and ethnoracial variations in digestive diseases
- Pathogenesis, diagnosis, treatment, and surveillance of cholangiopathies (e.g. primary sclerosing cholangitis)
- Training the next generation of culturally-competent academic gastroenterologists

In the News
- EVendo Score Webpage Goes Live (2019)
The EVendo Score — developed to noninvasively, quickly and reliably predict the presence and size of esophageal varices for risk stratification purposes in patients with cirrhosis — is now live online and available in MDCalc. It was developed and validated by James H. Tabibian, MD, PhD, director of endoscopy at Olive View-UCLA Medical Center, and recent UCLA fellowship graduates Tien Dong, MD, and Amir Kalani, MD, PhD, along with other colleagues. The full original article, “Machine Learning-based Development and Validation of a Scoring System for Screening High-Risk Esophageal Varices,” was published in the August 2019 issue of Clinical Gastroenterology and Hepatology.
