Research
Activities
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 Environmental
Research, the establishment of the Academy for Creative Media, bioinformatics, and
campus wide distance learning activities.
