Biography
Gultekin Ozsoyoglu was born in Turkey, and received degrees BS in Electrical Engineering, and MS in Computer Science from the Middle East Technical University in Ankara, Turkey, in 1972 and 1974, respectively. He received the PhD degree in Computing Science from the University of Alberta, Edmonton, Alberta, Canada, in 1980. He is presently a professor at CWRU. He published in database, security, multimedia computing, and real-time computing conferences and journals such as ACM Transactions on Database Systems, IEEE Transactions on Software Engineering, IEEE Transactions on Knowledge and Data Engineering, and Journal of Computer and System Sciences. He has served in program committees and panels of database conferences such as ACM SIGMOD, VLDB, IEEE Data Engineering. He was an ACM national lecturer, program chair of 3rd Statistical and Scientific Database Conference, workshops general chair of the CIKM'94 and CIKM'96 Conferences, Research Prototypes chair of ACM SIGMOD'94 conference, a guest editor for IEEE Transactions on Knowledge and Data Engineering, general chair of the11th Scientific and Statistical Database Management Conference and Co-Chair of the NSF'2000 Information and Data Management Workshop.
