Bruce Hajek's work has significantly furthered the integration of computers and communications systems. His many papers have taken the chaotic field of communication networking and given it a coherence and conceptual structure that it did not have previously. In the early 1980s, he led research that proved the stability of dynamically controlled ALOHA multiple-access. He and his students also developed algorithms for dynamic routing and transmission scheduling. These innovations showed that determinism in service time minimizes waiting time in network queues.
An IEEE Fellow and a member of the U.S. National Academy of Engineering, he has served as president of the IEEE Information Theory Society and was among eight winners of the USA Mathematical Olympiad in 1973. Dr. Hajek is a professor in the Electrical and Computer Engineering Department at the University of Illinois at Urbana-Champaign.
