Prof. Hongzhang Chen is working as the vice director and the supervisor of State Key Laboratory of Biochemical Engineering, as well as in editorial board of the Chinese Journal of Process Engineering. Prof. Chen is the chief scientist of National Basic Research Program of China and the chief scientist of the Innovative Engineering Program ‘Biomass and Solid-state Fermentation’, which is supported by Chinese Academy of Sciences. Prof. Chen’s research focuses on Ecological Biochemical Engineering and Cellulose Biotechnology. Currently the research explores new types of solid-state fermentation techniques, devices and processes, and clean fractionation using steam explosion techniques for efficient pretreatment in cellulose conversion to useful biorenewable materials, chemicals and biofuels. All the fields mentioned above are supported by the National Basic Research Program (“973” Program), the National High Technology Research and Development Program ("863"Program), National Natural Science Foundation of China, National Key Technology R&D Program, CAS Innovation Program, and so on. Prof. Chen and his group have published more than 150 papers in the peer reviewed internal and international scientific journals and 7 books, have applied 120 invention patents of China and 3 international invention patents (authorized 50, 1 USA patent). Noteworthy, about 10 patents have been industrialized.
