Research Interest

Mitochondria are organelles that serve as a hub for cellular signaling and the biogenesis of indispensable metabolites. We aim to understand how mitochondrial homeostasis is maintained under challenging physiological and disease conditions. We focus on stress caused by perturbations in mitochondrial protein import which is associated with multiple human disorders as well as with aging and neurodegenerative diseases.
