Prof. Dr. Qingsheng Qi, received his Ph.D in University of Muenster, Germany. Then he became a staff member in University of Chemnitz, Germany. Since 2004, he is full professor in State Key Laboratory of Microbial Technology in Shandong University, People’s Republic of China. Meanwhile, he is joint professor of National Glycoengineering Research Center. Dr. Qi has made many important contributions in setting up metabolic pathways of polyhydroxyalkanoates in E. coli. His current research is focusing the development of metabolic pathways for the efficient production of biochemicals and other compounds in different kinds of microorganisms, including 5-aminolevulinic acid, and tryptophan. He also developed/improved many general methods for metabolic engineering and synthetic biology. He published approximately 100 papers in international and national journals, such as Metabolic Engineering, Appl. Environ. Microbiol., and Microbial Cell Factories.
