My current research interests include computer graphics and animation and graphical database systems. I have published papers in the areas of graphical databases, expert systems, intelligent tutoring systems, theory of algorithms, operations research, and formal language theory. One of my current research interests is the extension of database query languages to support computer graphics and animation information. Currently I am involved with information technology applications related to the establishment of the Academy for Creative Media, bioinformatics, and campus and system wide distance learning activities.
