Wesley W. Chu, Professor

Wesley Chu is a Professor of Computer Science and was the past chairman (1988-1991) of the Computer Science Department at the University of California, Los Angeles. He received his B.S.E. (EE) and M.S.E (EE) from the University of Michigan in 1960 and 1961. He received his Ph.D. (EE) from Stanford University in 1966.

From 1988 to 1991, he was the Principal Investigator of ONR contract on Fault Tolerant Distributed Database Systems, and from 1989 to 1991, he was the Co-Principal (Dr. Popek, the Principal Investigator) of a DARPA contract on Very Large Distributed Information Processing Systems. From 1991 to present, he is the Co-Principal Investigator of a DARPA contract on Large Scale Filing and Data Management Environments. From 1991 to 1993, he is the principal investigator of the NSF contract on A Knowledge-Based Multimedia Medical Distributed Database System.

From 1964 to 1966, he worked on the design of large-scale computers at IBM, Menlo Park and San Jose, California. From 1966 to 1969, he researched computer communications and distributed databases at Bell Laboratories, Holmdel, New Jersey. He joined the University of California, Los Angeles in 1969. He directs a research group at UCLA in the areas of computer communications and networking, distributed processing, and knowledge based distributed databases. He is also a consultant to government agencies and private industries. He has authored or co-authored more than 100 articles on information processing systems and has edited three textbooks: Advances in Computer Communications, (Artech House, 1st ed. 1974 and 2nd revised ed. 1977), Centralized and Distributed Database Systems (co-edited with P. P. Chen, IEEE Computer Society, 1979), and Distributed Systems, Vol. I: Distributed Processing Systems, Vol.II: Distributed Database Systems (Artech House, 1986).

Dr. Chu is a Fellow of IEEE. He was the program co-chairman for the First International Conference on Data Engineering, and the program co-chairman for the 12th International Conference on VLDB in 1986. He was an associate editor for the IEEE Transactions on Computers for the field of computer networking and distributed processing systems (1978-1982) and received a meritorious award for his service to the IEEE (1983). He was the workshop co-chair of the IEEE First International Workshop on Systems Management, April 1993 and received a Certificate of Appreciation award for his significant service. He is currently a member of the Editorial Board of the Journal of Very Large Data Bases and an Associate Editor for the Journal of Data and Knowledge Engineering. Dr. Chu is the Principal Investigator of an ARPA contract of $1,664,000 (from March 1991 to April 1995) for researching and developing CoBase.
