About Khalid Sayood
Khalid Sayood received his undergraduate education at the Middle East Technical University, Ankara, Turkey, and the University of Rochester, Rochester, NY. He received the B.S. and M.S. degrees from the University of Rochester, and the Ph.D. degree from Texas A&M University, College Station, TX, in 1977, 1979, and 1982 respectively, all in electrical engineering.
He joined the Department of Electrical Engineering at the University of Nebraska-Lincoln in 1982, where he is currently serving as Henson Professor of Engineering. He spent the 1995-1997 academic years at the TUBITAK Marmara Research Center and Bogazici University in Turkey. He is the author of "Introductionto Data Compression," now in its second edition, and the editor of "The Lossless Compression Handbook."
