Self-introduction
Our research is mainly focused on dissecting the molecular mechanisms of the intracellular protein and membrane trafficking in the secretory and vacuolar pathways of plant cells, and its roles in the biological processes including plant growth and development, cell differentiation, and interaction between plant and environment.

Research Interests
◆ Molecular mechanism of protein secretion
◆ Characterization of vacuolar trafficking pathway
◆ Molecular mechanism of seed storage protein transport
◆ Plant bioreactor
