The Chen Laboratory focuses on molecular physiology in plants and microalgae. We are currently interested in three research areas: (1) mechanisms of storage lipid formation and acyl-trafficking at molecular and biochemical levels, (2) coordination of lipid biosynthesis, cell development and other pathways (such as starch biosynthesis and carotenoid biosynthesis), and (3) biotechnological strategies for increasing the production of oil and related bio-products.

Research Interests

Lipid biotechnology, Plant molecular physiology, Microalgal biotechnology, molecular biology, Biochemistry, Cell and Development
