He has published over 140 peer-reviewed publications in leading scientific journals including seminal reviews on the disease biology of non-alcoholic steatohepatitis (NASH) and liver fibrosis.

Dr. Feldstein's research laboratory has provided key evidence to support the current accepted theory of the role of hepatic lipid compartmentation and lipotoxicity in the pathogenesis of steatohepatitis development. Recently, he characterized a pathogenic role of NLR inflammasomes in liver inflammation and fibrosis. His lab has established cell-free systems, cell culture systems, precision-cut liver slices and murine models of steatohepatitis to test novel therapies. He has also pioneered the development of non-invasive blood tests to monitor liver damage. Dr. Feldstein has contributed to the development of preclinical, translational and clinical research protocols for a number of non-invasive tests and therapeutic agents.
