Biography

Hitay Özbay is a 1981 graduate of Galatasaray Lisesi, Istanbul, Turkey. He received the B.S. degree in Electrical Engineering from Middle East Technical University (Ankara, Turkey) in 1985, the M.Eng degree in Electrical Engineering from McGill University (Montreal, Canada) in 1987, and the Ph.D. degree in Control Sciences and Dynamical Systems from the University of Minnesota, (Minneapolis, USA) in 1989. He was an Assistant Professor of Electrical Engineering at the University of Rhode Island from September 1989 to December 1990. He was with the The Ohio State University, Department of Electrical and Computer Engineering,  (1991—2006).  In 2002, when he was on leave from the Ohio State University, Professor Hitay Özbay joined the Electrical and Electronics Engineering Department of Bilkent University. He served as an Associate Editor on the Editorial Board of the IEEE Transactions on Automatic Control (1997-1999), and was a member of the Board of Governors of the IEEE Control Systems Society (1999). He was an Associate Editor of Automatica (a journal of International Federation of Automatic Control), 2001-2007, and was vice-chair of the Technical Committee Networked Control Systems of IFAC, 2005-2008. Currently he is on the Editorial Board of Journal of Control Science and Engineering, and Applied and Computational Mathematics. Dr. Özbay has authored/co-authored many technical papers in the area of robust control of infinite dimensional systems, and engineering applications of this theory.
