Metrics for Academic and Research Impact

Wenjun Zhang studied physics and materials science at Lanzhou University, PR China. (B.Sc. 1988, M. Sc. 1991, Ph.D. 1994).  He was a post-doc at the Fraunhofer institute for Surface Engineering and Thin Films (FhG-IST) in Braunschweig, Germany, from 1995 till 1997. He became a research fellow in City University Hong Kong from 1997 till 1998, then spent two years in National Institute for Research in Inorganic Materials (NIRIM), Japan as a Science and Technology Agency (STA) Fellow. In December 2000 he joined City University Hong Kong again as a senior research fellow. He is now a Professor in the Department of Physics and Materials Science, and he is also the deputy director of the Center Of Super Diamond and Advanced Films (COSDAF).

Prof. Zhang has been served as guest editor of Advanced Materials, associate editor of Nano-Micr Lett. (Springer), editorial board member of Scientific Reports, and international advisory panel member of Materials Research Express (MRX) by The Institute of Physics (IOP). He has chaired/co-chaired The 68th IUVST Workshop: Multifunctional Surface Engineering for Advanced Energy Applications (2012), The 11th Cross-Strait Workshop on Nano Science and Technology (CSWNST11, 2014), and International Conference on Biomedical Application of Nanomaterials (ICOBAN2015).

Prof. Zhang is appointed as a Visiting Professor in Siegen University, Germany; Guest Professor in Technical Institute of Physics and Chemistry (CAS), Hefei University of Technology, Soochow University; and Cuiying Guest Professor (萃英讲席教授), Lanzhou University, PRC.
