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
