Research Interest
Mitochondria dysfunction is associated with various diseases and aging. To maintain healthy mitochondrial network, mitochondria are equipped with several systems that can evoke stress-signaling pathways. My lab is focusing on the stress-sensing mechanisms of mitochondrial proteins. We are especially interested in the stress-dependent regulation of mitochondrial proteases and mitochondrial import machineries. My research goal is to provide therapeutic targets for mitochondria dysfunction-related diseases through the manipulation of stress-signaling in mitochondria.
