Summary

Charles E. Leiserson received the B.S. degree in computer science and mathematics from Yale University, New Haven, Connecticut, in 1975 and the Ph.D. degree in computer science from Carnegie Mellon University, Pittsburgh, Pennsylvania, in 1981. In 1981, he joined the faculty of the Massachusetts Institute of Technology, Cambridge, Massachusetts. He currently holds the position of Professor of Computer Science and Engineering in the MIT Department of Electrical Engineering and Computer Science and is a Margaret MacVicar Faculty Fellow. He leads the Supercomputing Technologies (SuperTech) research group and is member of the Theory of Computation research group in the MIT Computer Science and Artificial Intelligence Laboratory. Prof. Leiserson's research centers on developing theoretical principles of parallel and distributed computing, especially as they relate to engineering reality. Prof. Leiserson pioneered the development of VLSI theory and has written many papers on VLSI algorithms, graph layout, and computer-aided design. His contributions include the divide-and-conquer method of graph layout and the ``retiming'' method for optimizing digital circuitry. Prof. Leiserson has been a leader in the development of parallel computing. As a graduate student at Carnegie Mellon, he wrote the first paper on ``systolic'' architectures with his advisor H.T. Kung. While Corporate Fellow of Thinking Machines Corporation, he designed and led the implementation of the network architecture for the Connection Machine Model CM-5 Supercomputer, which incorporated the ``fat-tree'' interconnection network he developed at MIT. Prof. Leiserson has designed and engineered many parallel algorithms, including ones for matrix linear algebra, graph algorithms, optimization, and sorting. Of particular note, he introduced the notion of ``cache-oblivious'' algorithms, which exploit a hierarchy of processor caches efficiently without any tuning of cache-dependent parameters. Prof. Leiserson's academic work has won many other awards. His Ph.D. dissertation, Area-Efficient VLSI Computation, which deals with the design of systolic systems and with the problem of determining the VLSI area of a graph, won the ACM Doctoral Dissertation Award in 1982, as well as the Fannie and John Hertz Foundation Doctoral Thesis Prize. In 1985 he received a Presidential Young Investigator Award from the National Science Foundation. His textbook, Introduction to Algorithms, coauthored with Ronald L. Rivest, and Thomas H. Cormen, was named Best 1990 Professional and Scholarly Book in Computer Science and Data Processing by the Association of American Publishers. The textbook, now in its third edition with an additional coauthor, Clifford Stein, has been the leading textbook on computer algorithms for many years and is the most cited publication in computer science, according to CiteSeerX. Prof. Leiserson's publications are cited over 10,000 times in the literature, also according to CiteSeerX. Prof. Leiserson is a member of the ACM, IEEE, and SIAM. In 1995-6, he was Shaw Visiting Professor in the Department of Information Systems and Computer Science at the National University of Singapore. He is past Computer Science Program Chair for the Singapore-MIT Alliance, a distance-education initiative in which students in Singapore take MIT classes. He held an Adjunct Professorship at the National University of Singapore for many years; was Director of System Architecture, Director of Research, and Network Architect at Akamai Technologies, Inc. of Cambridge, Massachusetts; and was founder and CTO of Cilk Arts, Inc. of Burlington, Massachusetts, before the company was bought by Intel Corporation. A dedicated teacher, Prof. Leiserson has directly supervised 22 Ph.D. students and over 50 Master's and Bachelor's students.
