Biographical sketch Dr. Cheung received his B.Sc. degree from University of Hong Kong in 1970 and Ph.D. degree in nuclear physics from California Institute of Technology in 1976. After graduation, he joined Bell Laboratories to conduct pioneering research in early single-mode fiber optic systems. In 1984 he became District Manager of the Advanced Lightwave Technology Group in Bellcore, where he created three leading edge research programs in high-speed, coherent, and subcarrier-multiplexed lightwave systems. In 1989, he was on leave as a visiting scientist at the School of Computer Science in Carnegie Mellon University. He helped create the Gigabit Nectar Testbed in Pittsburgh, one of the 5 early gigabit testbeds sponsored by DARPA and NSF. He returned to Bellcore as an Executive Director in the Applied Research Area, where he managed a wide range of research programs in high-speed networking, terabit switching and network management systems. He was one of the originators of the Advanced Technology Demonstration Network Testbed (ATDNet), the first 2.5 Gb/s ATM testbed in Washington DC sponsored by six government agencies. He chaired the SONET OC-192 (10 Gb/s) and ATM Self-healing Ring Consortium, a key Technology Reinvestment Project (TRP) initiated by President Clinton. Dr. Cheung was the principal investigator of SuperNet Broadband Local Trunking, a Next Generation Internet (NGI) project sponsored by DARPA. In this project, he and his team invented the burst mode variable bit rate technique, a key enabling component in optical packet and burst switching networks currently pursued by many research groups. Nim Cheung was a member of SAIC’s Executive Science and
Technology Council, and has served on the EE advisory boards of
Columbia University, Polytechnic University of New York, and New
Jersey Institute of Technology. He is a Telcordia Fellow and a
Fellow of IEEE. He has been an active leader in the IEEE
Communications Society, serving as VP of Technical Affairs
(1996-97), Chair of the Strategic Planning Committee (1998-99),
Distinguished Lecturer (2001-04), and VP of Society Relations
(2004-05). Dr. Cheung has published over 120 papers, and has served
in different editorial positions. He has organized numerous
conferences and workshops for different professional societies,
including several online multicasting events.
