Overview
Research in my 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.
