Theoretical and algorithmic aspects of modern computing environments, such as clusters and grids.


Professor Rosenberg's research focuses on developing algorithmic models and techniques to deal with the new modalities of "collaborative computing" that result from emerging technologies such as cluster computing, web computing, and grid computing. He is the (co)author of more than 150 technical papers on these and other topics in theoretical computer science and discrete mathematics, and he is the coauthor of a 2001 book: Graph Separators, with Applications.


Ph.D., Applied Mathematics, Harvard University (1966), A.M., Applied Mathematics, Harvard University (1963), A.B., Mathematics, Harvard College (1962). Professor Rosenberg has been on the faculty of the University of Massachusetts Amherst since 1986, and is currently a Distinguished University Professor of Computer Science and Co-Director of the Theoretical Aspects of Parallel and Distributed Systems (TAPADS) Group. Previously he was a Professor of Computer Science at Duke University from 1981 to 1986, and a Research Staff Member at the IBM Watson Research Center from 1965 to 1981. Professor Rosenberg was a Lady Davis Visiting Professor at the Technion (Israel Institute of Technology), and a Fulbright Senior Research Scholar at the University of Paris-South.
