General description research focus

In recent years, my main research interest has been cytoskeleton organization and dynamics, cell adhesion, and cell signaling. Specifically, I focus on plectin-dependent regulation of actin microfilaments, intermediate filament cytoarchitecture, adhesion mediated signaling, and cell motility using molecular cell biology in various cell types derived from transgenic mice models. The current aim of my lab has the following objectives: 1) identification of genes with unique and essential functions in simple epithelia; 2) generation of mouse models with targeted selected genes; and 3) phenotypic characterization of generated mouse models addressing gene functions in healthy and diseased simple epithelia. My research has practical applications to the understanding of liver fibrosis, inflammatory bowel diseases and carcinogenesis.
