Prof. Zhang, a Canadian Citizen, was born in Shanghai in 1962. He got his B.S. in Physics from The University of Science & Technology of China in 1985, and PhD in Applied Physics from The University of Tokyo in 1992. From1992 to 1996 he worked in Olympus Co., Ltd., Tokyo, Japan as a Research Engineer. From 1996 to 2000 he worked in National University of Singapore as a Lee Kuan-Yew Outstanding Postdoctoral Fellow. From 2000 to 2004 he worked in Nova Crystal Inc., California, the USA as a Senior Engineer. From 2004 to 2006, he worked in Simon Fraser University, Burnaby, Canada as a Research Scientist. From 2006 to 2008, he worked in Wuxi Bluestar Electronics Inc. as Chief Technical Officer. He joined the School of Electronic Science and Engineering, Southeast University as a Professor since 2009.

Prof. Zhang has been engaged in the research and development of GaAs-, InP-, and GaN-based optoelectronic materials and devices for more than 25 years. His current research interests include: MOCVD growth of GaN-based blue and UV LEDs on both sapphire and silicon substrates; development of the fabrication process for AlGaN/GaN HEMTs, HBTs, and other power electronic devices; research and development of ultrafast electrically- and optically-controllable terahertz wave modulators. He has published more than 40 SCI papers, and two book Chapters in English in Appl. Phys. Lett. Opt. Express, Jpn. J. Appl. Phys., and other well-known scientific journals. He has filed more than 20 patent applications and got 7 granted in Japan, Singapore, the USA, and China.
