"For outstanding achievements, sustained leadership, and dedicated service to the IEEE Computer Society"

 

Benjamin W. Wah is the Franklin W. Woeltge Endowed Professor of Electrical and Computer Engineering and a Professor of the Coordinated Science Laboratory of the University of Illinois at Urbana-Champaign, Urbana, IL. He received his B.S. and M.S. degrees in electrical engineering from Columbia University in 1974 and 1975, respectively, and his M.S. and Ph.D. degrees in computer science from the University of California, Berkeley, CA, in 1975 and 1979, respectively.

Previously, he had served on the faculty of Purdue University (1979-85), as a Program Director at the National Science Foundation (1988-89), as Fujitsu Visiting Chair Professor of Intelligence Engineering, University of Tokyo (1992), and as McKay Visiting Professor of Electrical Engineering and Computer Science, University of California, Berkeley (1994).

Wah is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE), the Association for Computing Machinery (ACM), and the American Association for the Advancement of Science (AAAS). In 1989, he was awarded a University Scholar of the University of Illinois; in 1998, he received the IEEE Computer Society Technical Achievement Award; in 2000, the IEEE Millennium Medal; in 2003, the Raymond T. Yeh Lifetime Achievement Award from the Society for Design and Process Science; and in 2006, the IEEE Computer Society W. Wallace McDowell Award. He has published over 260 papers, two authored books, and three edited books.

As an individual researcher, Wah has made fundamental contributions to nonlinear optimization. He has developed the mathematical foundation and the algorithms for solving large-scale discrete, continuous, and mixed constrained optimization problems whose functions are not necessarily in closed form. These problems exist in many engineering fields, including production planning, scheduling, system design, artificial intelligence, control systems, semiconductor manufacturing, and operations research. Based on a key observation that the constraints in many of these application problems are highly structured and involve variables with strong spatial or temporal locality, he has developed the mathematical foundation for partitioning large-scale application problems by their constraints into a small number of much simpler subproblems. Because each subproblem has only a fraction of the original constraints, it is a significant relaxation of the original problem and has an exponentially lower complexity. As a result, his approach can effi ciently solve many problems that are intractable to existing solvers. His research provides the key technology for reducing the complexity of large-scale problems in spacecraft and satellite planning. Its success has been demonstrated in SGPlan, a planner that won the First Place Awards in the 4th International Planning Competition in 2004 and the 5th International Planning Competition in 2006. It has also been shown in CPOpt, a nonlinear programming solver that can solve many large-scale continuous and mixed-integer optimization problems that cannot be solved by some of the best solvers today.

As a volunteer leader, Wah has made numerous contributions in promoting the computing profession. During his service as the IEEE Computer Society President in 2001, he was instrumental in launching numerous initiatives. Two of his many accomplishments were to establish the IEEE Computer Society as a total information provider and to provide continuing education for computer professionals worldwide.

Under his leadership, the IEEE Computer Society launched a distance learning program that offered hundreds of free online courses for its members. He cofounded the IEEE Transactions on Knowledge and Data Engineering and served as its Editor-in-Chief between 1993 and 1996. He had chaired many IEEE Computer Society conferences and was the International Program Committee Chair of the IFIP World Congress in 2000. He chaired the IEEE-CS Transformation Task Force in 2006 and currently serves as the Society's representative to the Computing Research Association and chairs the IEEE Computer Society Governance Restructuring Subcommittee.

Ben and his wife, Christine, have two daughters, Catherine and Elaine.
