Research Overview

Joel Seiferas (SB mathematics, SM and PhD computer science, MIT) is author of the Machine-Independent Complexity chapter of the Handbook of Theoretical Computer Science and the chapter on the AKS sorting network in the Encyclopedia of Parallel Computing. Joel, too, has been named an ACM Distinguished Scientist, in recognition of fundamental research in automata-based complexity, simulations, algorithms, and lower bounds—research that includes major work on nondeterminism, hierarchies, and complexity classes; simulation of multihead tapes; lower bounds via Kolmogorov complexity; string matching; sorting networks; and cellular automata.
