He joint in Beijing Institute of Posts and Telecommunications (Beijing University of Posts and Telecommunications now) to participate in the undergraduate study in 1975, obtained Master degree of Engineering in 1981, and stayed in the university to work as a teacher after graduation up to now. He studied abroad at Northeast University of Japan in 1987, and took part in the training of high-class manager for telecommunications at AT&T of USA in 1994. He focuses the research on wireless telecommunication, telecommunication network, biomedicine, photoelectronics, microelectronics, and etc. He takes charge in many research projects in the field of telecommunication early or late, and is familiar with development trends of national and international telecommunication technology. The research projects were attended as principle or main researcher, including Numerical model of physical flow field based on anatomical structure (Natural Science Foundation of China), Research on 3G system performance using HSDPA, Research on optical and wireless connect technology inside room, Research on integrated management and concentrated inspection system of telecommunication networks, Manufacture of strain sensor of optical fiber, and etc. Research achievements and prizes are gained, such as Research on integrated management and concentrated inspection system of telecommunication networks (the 3rd award of the development of the science and technology in Ministry of education in 2000), and Optical repeaters mixed and inherited by thin and thick films (the 3rd award of the development of the science and technology in Ministry of posts and telecommunications in 1991). He published a series of papers in national and international journals, including Status in quo and development trend of optical telecommunications in free space (Data Traffic in China, written in Chinese, 2004.12), Data storage technology applied in scheme management of SDH (Transaction on BUPT, 2002. 2), Multi-state, Chaos-Shift Keying Modulation System: Analysis and Realization (Transaction on the universities of Posts and Telecommunications of China, written in English, 1997), and etc. Now he works on telecommunication design for the future, wireless telecommunication system, optical and wireless telecommunication system, and etc. The major of recruiting master students is microelectronics and solid- state electronics. Research direction and major catalog is wireless telecommunication and electronic engineering technology.
