Chair and Professor
|Office:||6133 Sennott Square|
Dr. Znati obtained the MS (Computer Science) from Purdue University, and the PhD (Computer Science, 1988) from Michigan State University.
He joined the faculty of the Department of Computer Science with a joint appointment in the Graduate Program in Telecommunications at the University of Pittsburgh in 1988. Prior to that he was a member of the Syrius research group headed by Dr. G. Lelan at INRIA (France), which investigated issues related to the design and analysis of distributed data base systems.
Dr. Znati's current research interests focus on the design of network level channel abstractions for real-time communication networks to support multimedia environments, the design and analysis of medium access control protocols to support distributed real-time systems, and the investigation of fundamental design issues related to distributed systems in the areas of machine learning, cognitive modeling, problem solving, and analogical reasoning.
