William Kocay (short biography)

Dr. Kocay obtained his Ph.D. in Combinatorics and Optimization from the University of Waterloo in 1979. He is currently a member of the Computer Science Department, and an adjunct member of the Mathematics Department, at the University of Manitoba, and a member of St. Paul's College, a college affiliated with the University of Manitoba. He has published numerous research papers, mostly in graph theory and algorithms for graphs. He was managing editor of the mathematics journal \emph{Ars Combinatoria} from 1988 to 1997. He is currently on the editorial board of that journal. He has had extensive experience developing software for graph theory and related mathematical structures.

Donald L. Kreher (short biography)

Dr. Kreher obtained his Ph.D. from the University of Nebraska in 1984. He has held academic positions at Rochester Institute of Technology and the University of Wyoming. He is currently a University Professor of Mathematical Sciences at Michigan Technological University, where he teaches and conducts research in combinatorics and combinatorial algorithms. He has published numerous research papers and is a co-author of the internationally acclaimed text ``Combinatorial Algorithms: Generation Enumeration and Search'', CRC Press, 1999. He serves on the editorial boards of two journals.

Professor Kreher is the sole recipient of the 1995 Marshall Hall Medal, awarded by the Institute of Combinatorics and its Applications.
