    Professor of Electrical and Computer Engineering

    Biography

    Ha H. Nguyen received the B.Eng. degree from the Hanoi University of Technology (HUT), Hanoi, Vietnam, in 1995, the M.Eng. degree from the Asian Institute of Technology (AIT), Bangkok, Thailand, in 1997, and the Ph.D. degree from the University of Manitoba, Winnipeg, MB, Canada, in 2001, all in electrical engineering. He joined the Department of Electrical and Computer Engineering, University of Saskatchewan, Saskatoon, SK, Canada, in 2001, and became a Full Professor in 2007. He holds adjunct appointments at the Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada, and TRLabs, Saskatoon, SK, Canada, and was a Senior Visiting Fellow in the School of Electrical Engineering and Telecommunications, University of New South Wales, Sydney, Australia during October 2007-June 2008. His research interests include spread spectrum systems, error-control coding and diversity techniques in wireless communications. Dr. Nguyen currently serves as an Associate Editor for the IEEE Transactions on Wireless Communications, the IEEE Transactions on Vehicular Technology and the International Journal on Information and Coding Theory. He is a coauthor, with Ed Shwedyk, of the textbook "A First Course in Digital Communications" (published by Cambridge University Press). Dr. Nguyen is a Registered Member of the Association of Professional Engineers and Geoscientists of Saskatchewan (APEGS).
