Dr. Greenberg joined our department as an Associate Professor in 1996 after teaching previously in the Department of Electrical Engineering at the University of Maryland. Dr. Greenberg received his Ph.D. in Electrical Engineering and Computer Science at M.I.T. in 1989 under the direction of Professor Charles Leiserson. His main research efforts have been on identifying good networks for general-purpose parallel computing and developing algorithms in a number of application areas, e.g., routing messages on networks, VLSI wire routing, and sequence analysis problems of interest to computational biologists.
