Dr. Toal's teaching responsibilities and research interests focus on the core areas of computer science --- software systems, data organization, knowledge representation, language, learning, and intelligence --- with a focus on programming language design. He is currently in charge of the capstone software engineering laboratory, providing students with experience in open source software development using agile methodologies drawn from years of consulting at both startup and established technology companies. His publications include several papers done with undergraduate students and faculty in other departments. Dr. Toal has been on the faculty since 1986 and has received both university and national teaching awards. Dr. Dionisio's personal research interests lie in interaction design and computer graphics, as well as in applications that cross and bridge computer science with other disciplines. His undergraduate courses in interaction design and computer graphics use JavaScript heavily, as does the health information system software that he co-develops at Medaxis Corporation.
