Brief Bio

Kyu-Young Whang graduated (Summa Cum Laude) from Seoul National University in 1973 and received the M.S. degrees from Korea Advanced Institute of Science and Technology (KAIST) in 1975, and Stanford University in 1982. He earned the Ph.D. degree from Stanford University in 1984. From 1983 to 1991, he was a Research Staff Member at the IBM T. J. Watson Research Center, Yorktown Heights, NY. In 1990, he joined KAIST, where he currently is a KAIST Distinguished Professor at the Department of Computer Science and the Director of the Advanced Information Technology Research Center (AITrc). His research interests encompass database systems/storage systems, object-oriented databases, multimedia databases, geographic information systems (GIS), data mining/data warehouses, XML databases, and data streaming. He is an author of over 100 papers in refereed international journals and conference proceedings (and over 150 papers in domestic ones).

Dr. Whang served as an IEEE Distinguished Visitor from 1989 to 1990, received the Best Paper Award from the 6th IEEE International Conference on Data Engineering (ICDE) in 1990, served the ICDE six times as a program co-chair and vice chair from 1989 to 2003, and served program committees of over 110 international conferences including VLDB and ACM SIGMOD. He was the program chair (Asia and Pacific Rim) for COOPIS'98, the program chair (Asia, Pacific, and Australia) for VLDB 2000, and a program co-chair of ICDE2006. He was the general chair of VLDB2006, PAKDD 2003, and DASFAA 2004. He twice received the External Honor Recognition from IBM. Dr. Whang is the Coordinating Editor-in-Chief of the VLDB Journal having served the editorial board as a founding member for thirteen years. He was an associate editor of the IEEE Data Engineering Bulletin from 1990 to 1993, Distributed and Parallel Databases Journal from 1991 to 1995, Int'l J. of GIS from 1994 to 2007, and IEEE TKDE from 2002 to 2006. He is on the editorial boards of the WWW Journal. He was a trustee of the VLDB Endowment from 1998 to 2004 and currently is a steering committee chair of the DASFAA Conference and a steering committee member of the IEEE ICDE and PAKDD Conferences. He served the IEEE Computer Society Asia/Pacific Activities Group as the Korean representative from 1993 to 1997.

Dr. Whang is a Fellow of the IEEE, a member of the ACM, and a member of IFIP WG 2.6.
