Roger S. Cheng (S'86-M'92) received the B.S. degree from Drexel University, Philadelphia, PA, in 1987, and both the M.A. and Ph.D. degrees from Princeton University, Princeton, NJ, in 1988 and 1991, respectively, all in electrical engineering.
From 1987 to 1991, he was a Research Assistant in the Department of Electrical Engineering, Princeton University, Princeton, NJ. From 1991 to 1995, he was an Assistant Professor in the Electrical and Computer Engineering Department of University of Colorado at Boulder. In June 1995, he joined the Faculty of Hong Kong University of Science and Technology, where he is currently an Assistant Professor in the Department of Electrical and Electronic Engineering. He also held visiting positions with Qualcomm, San Diego, in the summer of 1995, and with Institute for Telecommunication Sciences of NTIA, Boulder, CO, in the summers of 1993 and 1994. His current research interests include wireless communications, multiuser communications, spread spectrum CDMA, digital implementation of communication systems, wireless multimedia communications, information theory, and coding.
Dr. Cheng is the recipient of the Meitec Junior Fellowship Award from
the Meitec Corporation in Japan, the George Van Ness Lothrop Fellowship
from the School of Engineering and Applied Science in Princeton University,
and the Research Initiation Award from the National
Science Foundation. He was a member of the Technical Program Committees
of GLOBECOM98 and IEEE Wireless Communications and Networking Conference
(WCNC'99). He has served as Guest Editor of the special issue on Multimedia
Network Radios in the IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS,
Associate Editor of the IEEE TRANSACTION ON SIGNAL PROCESSING, and membership
chair for of the IEEE Information Theory Society.
