MOHAMMED J. ZAKI is currently an assistant professor of computer science at Rensselaer Polytechnic Institute. He is also an adjunct assistant professor in the Decision Sciences and Engineering Systems department. He received his M.S. and Ph.D. degrees in computer science from the University of Rochester in 1995 and 1998, respectively.

His research interests include the design of efficient, scalable, and parallel algorithms for various data mining techniques such as association rules, decision tree classification, clustering, and sequence mining. He is working on developing fast methods for the overall data mining process, from the initial data selection to the extraction and management of discovered knowledge.

Dr. Zaki has published over 25 papers on data mining and parallel computing. He was on the program committee of the 2nd Workshop on High Performance Data Mining, held in conjunction with the International Parallel Processing Symposium, April 1999. He is a member of the ACM (SIGKDD, SIGMOD), IEEE Computer Society and AAAI.

CHING-TIEN (HOWARD) HO received a B.S. degree in electrical engineering from the National Taiwan University in 1979 and M.S., M.Phil., and Ph.D. degrees in computer science from Yale University in 1985, 1986, and 1990, respectively.

He joined IBM Almaden Research Center as a Research Staff Member in 1989. He was manager of the Foundations of Massively Parallel Computing group from 1994 to 1996, where he led the development of collective communication, as part of IBM's MPL and MPI effort, for IBM SP-1 and SP-2 parallel systems. His primary research interests include communication issues for interconnection networks, algorithms for collective communications, graph embeddings, fault tolerance, and parallel algorithms and architectures. His current interests are data mining and on-line analytical processing. He has published over 80 journal and conference papers in these areas.

Dr. Ho is a co-recipient of the 1986 ``Outstanding Paper Award'' of the International Conference on Parallel Processing. He has received an IBM Outstanding Innovation Award, two IBM Outstanding Technical Achievement Awards, and four IBM Plateau Invention Achievement Awards. He has 11 patents granted or pending. He was on the Editorial Board of the IEEE Transactions on Parallel and Distributed Systems from 1995 to 1998. He is on the Editorial Board of the Journal of Interconnection Networks. He is one of program vice-chairs for the 1998 International Conference on Parallel Processing. He has served on program committees of many parallel processing conferences and workshops. He is a member of the ACM and the IEEE Computer Society.
