Research & Publications
Dr. Assis received his M.D. from Jefferson Medical College followed by internship and residency at Thomas Jefferson University Hospital in Philadelphia, where he was also Chief Resident. He completed training in gastroenterology and hepatology followed by transplant hepatology fellowships at Yale University.
His clinical and research interests are in autoimmune liver diseases. Specifically, he treats patients with autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis at his liver clinic. He also performs translational and basic research on autoimmune hepatitis using patient biospecimens in addition to work with animal models. He is investigating the link between the pro-inflammatory cytokine macrophage migration inhibitory factor (MIF) and autoimmune hepatitis, and the effect of psychological stress on autoimmune hepatitis.
In addition, Dr. Assis is an active member of the Adult Cystic Fibrosis Program at Yale. In this role, he evaluates and treats patients with Cystic Fibrosis who have GI or liver complications of their disease. He also consults on patients from outside Yale's Cystic Fibrosis program who have these complications.
