Organ Dysfunction- Mechanisms, Signaling and Biomarkers 

The broad interest of the lab focuses on the pathogenesis of liver disease, particularly complications of liver cirrhosis such as acute-on-chronic liver failure (ACLF) and on non-alcoholic fatty liver disease (NAFLD). Our work centers around interactions and cross-talk between the immune system and the liver. Recent studies by our group has demonstrated the expansion of CD177+ neutrophils in ACLF and its relationship with patient mortality. Students in the lab are currently investigating the basis of such immune regulation and the potential of harnessing this information in developing new therapeutic approaches. In addition to immune- liver cross talk, a major interest of our group is to carry out systematic and rigorous biomarker discovery studies using mass spectrometry driven omics approaches (proteomics and metabolomics) and recent work by our group has uncovered novel biomarkers of acute kidney injury in ACLF. Our approach is to combine clinical observations in liver disease with mechanistic studies in lab cell culture and animal models.
