Prof. Dr. Xiupu Zhang received a B.Sc. degree in electrical engineering from the Harbin Institute of Electrical Technology (now the Harbin University of Science and Technology), Harbin, China, in 1983, a M.Sc. degree in electrical engineering from the Beijing University of Posts and Telecommunications, Beijing, China, in 1988, and a Ph.D. degree in electrical engineering from the Technical University of Denmark, Lyngby, Denmark, in 1996. From 1983 to 1985, he worked in manufacturing fibers and fiber cables in China. From 1988 to 1992, he was engaged in the construction of telecommunication networks in Beijing. From 1998 to 2002, he worked as a senior engineer in the fiber-optics industry, involved in the design of repeaterless fiber-optic transmission systems, design of erbium-doped fiber amplifiers and fiber Raman amplifiers, design of optical transmitters and receivers, and the design of metropolitan optical networks, in North America, including Montreal and Ottawa, Canada, and Piscataway, NJ, USA. In June 2002, he joined Concordia University, Montreal, Quebec, Canada, where he was an Associate Professor. Currently, he is a full-time Professor at the Department of Electrical and Computer Engineering, at Concordia University. His current research interests include broadband and high linearity fronthaul transmission systems based on radio over fiber, quantum-dot semiconductor lasers, and broadband photodiodes with microwave packaging and antennas.
