He maintains a research laboratory that studies various mechanisms of lymphocyte activation that relate to immune tolerance and adoptive immunotherapy for cancer and chronic infection. In 2011, his research team published findings, which represented the first successful and sustained demonstration of the use of gene transfer therapy to treat cancer. Clinical trials utilizing this approach, in which patients are treated with genetically engineered versions of their own T-cells, are now underway for adults with chronic lymphocytic leukemia and adults and children with acute lymphoblastic leukemia. Early results in that group show that 90 percent of patients respond to the therapy, and more recently, trials of this approach have begun for patients with other blood cancers and solid tumors including pancreatic cancer, mesothelioma and the brain cancer glioblastoma. In 2014, it became the first personalized cellular therapy for the treatment of cancer therapy to receive the U.S. Food and Drug Administration’s prestigious Breakthrough Therapy designation.

He has published more than 350 manuscripts and is the recipient of numerous prizes and honors, including election to the Institute of Medicine in 2012, the William B. Coley award, the Richard V.

Dr. Tabas is the Richard J. Stock Professor and Vice-Chair of Research in the Department of Medicine and Professor of Pathology and Cell Biology (in Physiology and Cellular Biophysics) at Columbia University in New York City. Dr. Tabas has extensively studied multiple pathways involved in metabolic dysfunction-associated steatohepatitis (MASH) fibrosis, focusing on crosstalk between hepatocytes, liver macrophages, and hepatic stellate cells. His work has revealed key roles for a transcriptional regulator called TAZ and for the process of whereby macrophages clear dead hepatocytes in MASH liver (efferocytosis). Both of these discoveries have led to patent applications and drug development efforts led by pharma and biotech companies. Dr. Tabas also studies the mechanism of atherosclerosis and is currently investigating mechanisms and therapeutic targets that are common between MASH and atherosclerosis.
