Understanding Computation

Arnold L. Rosenberg is a distinguished university professor emeritus at the University of Massachusetts, Amherst.  He earlier held full-time positions as a professor at Duke and as a Research Staff member at the IBM Watson Research Center.  He has held research positions at Northeastern University and Colorado State University. He has been a visiting professor at the University of Toronto, a Lady Davis visiting professor at the Technion (Israel Inst. of Technology), and a Fulbright Senior Research Scholar at the University of Paris-South.  In 1996, he was elected a fellow of the ACM for his work on graph-theoretic models of computation, with a focus on theoretical studies of parallel algorithms and architectures, VLSI design and layout, and data structures. In 1997, he was elected a fellow of the IEEE for his fundamental contributions to theoretical aspects of computer science and engineering. Lenwood S. Heath is a professor in the Department of Computer Science at Virginia Tech. His research interests include theoretical computer science, algorithms, graph theory, computational biology and bioinformatics, computational genomics, complex networks, and computational epidemiology. He completed a Ph.D. in computer science (1985) at the University of North Carolina, Chapel Hill, an M.S. in mathematics (1976) at the University of Chicago, and a B.S. in mathematics (1975) at the University of North Carolina, Chapel Hill. Before joining the faculty at Virginia Tech in 1987, he was an instructor of applied mathematics and member of the Laboratory of Computer Science at MIT. He is a member of SIAM, a member of the ACM, and a lifetime senior member of the IEEE. He is a managing editor of the Journal of Interconnection Networks
