Research interest


The nature of life is maintenance of metabolic homeostasis against the challenges from the environment. We are interested in understanding a fundamental question in cell biology: how cells maintain homeostasis in response to stresses. We focus on investigating three interconnected cellular processes: autophagy (a key mechanism for clearance and renewal of cellular components in response to stress), unconventional secretion (a recently identified ER-Golgi trafficking-independent secretion process under stress conditions), and organelle interaction (coordinated action of organelles through membrane contact to cope with stress). We employ cutting-edge techniques of cell biology, biochemistry, mouse model, and computational biology to study the mechanism and coordination of the three cellular processes, as well as to understand their biological functions and the related human diseases.
