Areas of Interest:
I have been actively involved in the field of alcoholic liver injury for more than 30 years, with special emphasis on alcohol’s deleterious effects on protein trafficking. Our laboratory is well known for its contributions in this area, especially on a role for functional asialoglycoprotein receptor in the pathogenesis of liver injury. In particular, I have used in vitro biochemical-based experimentation combined with in vivo animal models to define important effects of toxin exposure (including ethanol exposure) on endocytic internalization and recycling of hepatocyte receptors. Our current work has extended the studies on alcohol-induced alterations in protein trafficking to alcohol’s effects on lipid droplet trafficking. In these studies we are part of a MPI-NIAAA funded program to provide a comprehensive approach using biochemical, cell biological, imaging, and animal-based methods toward understanding how ethanol consumption and/or administration affects the dynamics of lipid droplets in hepatocytes. In addition to my role as a Principal Investigator on an NIH grant, and my role as a VA Research Career Scientist, I have been actively involved in mentoring young investigators.
