    Collapse Overview
    Research in my lab is centered on understanding the basic principle of cellular processes including apoptosis and autophagy, cell cycle regulation and genomic stability, as well as intracellular trafficking matrix in the development of cancer and infectious disease. Being a lysosome-dependent quality control mechanism and house-cleaning activity of the cessll, autophagy (Greek for self-eating) has been increasing recognized being essential for cells to maintain homeostasis and also protect the organism against diverse pathogens and cancerous cells.
