David Assis, MD, is a hepatologist who treats patients at Yale New Haven Hospital with liver and digestive diseases. He focuses on chronic liver ailments, as well as liver and digestive complications of cystic fibrosis. He tells his patients, “We will support you throughout this process and use cutting-edge discoveries to offer the best possible care.”

Dr. Assis became a hepatologist because he was fascinated by autoimmune liver diseases. An assistant professor of medicine (digestive diseases) at Yale School of Medicine (YSM), he dedicates his research to investigating the causes, mechanisms and treatment of these diseases. In 2014, he was honored with YSM’s Kushlan Junior Faculty Award for his research work.

A member of the America Association for the Study of Liver Diseases, Dr. Assis is optimistic about developing better treatments for patients. “There is much to be discovered in this field, and we expect to see great progress within the next several years,” he says.
