RESEARCH OVERVIEW

Research in our laboratory is focused on the understanding of molecular mechanisms that regulate the mitochondrial contribution to programmed cell death and inflammation signaling. Both processes are fundamental to a variety of diseases, including cancer, neurodegeneration and infectious diseases.  In this context we are specifically interested in mitochondrial autophagy and interorganellar interactions, including with the endolysosomal compartment.  We are applying a combination of fluorescence microscopy, molecular and cell biological, and biochemical approaches.  Our studies aim at uncovering novel cell biological insights that can be exploited to combat diseases.
