The central purpose of the Nonalcoholic Fatty Liver Disease (NAFLD) SIG is to provide a forum to share ideas, foster collaboration and brainstorm together as an academy of basic and translational investigators. Our mission is to study the pathogenesis, diagnosis, natural history and development of therapeutics for nonalcoholic liver disease. The NAFLD SIG sponsors programs at the AASLD Annual Meeting, identifies emerging topics in NAFLD, and supports the educational mission of AASLD.
