Research and development are primary functions of this department. Faculty research runs the gamut from the abstract issues of theoretical computing through the machine cognition concepts of artificial intelligence, mathematical software needs of scientific computing, and design issues in architectures and languages, databases, distributed systems and real-time systems, to more application-oriented areas such as computer vision, graphics, image processing and expert systems. Faculty research interests have become greatly diversified, and research is being carried out in the many applications areas as well as the main facets of computer science.
