Brief Biography
Prof. DENG Luogen, received his BEng and MEng degrees in precision mechanical engineering and optics from the Dalian Institute of Technology, China, in 1982 and 1985,respectively, and his PhD degree in optics and precision metrology from Tsinghua University , Beijing, China, in 1989. He was a postdoctoral research fellow with the Department of Optical Engineering, Beijing Institute of Technology (BIT), China, from 1990 to1992, where he worked on adaptive optics, real-time wavefront sensing, and weak light imaging techniques. Dr. Deng was an associate professor with the Department of Applied Physics, BIT, China, from 1993 to 1997. He has been a full professor in the Department of Applied Physics (School of Physics), BIT, China, since 1998.  Prof. Deng was a visiting scholar with the Department of Electrical Engineering, University of California, Los Angeles, from 1999 to 2000. As a visiting Professor, he also worked in the Department of Physics, University of Toronto, Canada, in 2009.  Prof. Deng has presided over many important research projects including those of the National Natural Science Foundation of China. His current research interests are mainly nano-optics, liquid crystal optics, random lasing, plasmonics and its applications.
