I have been working in the areas of software engineering, requirements engineering, software quality management, fuzzy logic, collaborative systems, and database systems since 1982. My research focus is to develop software engineering methods and tools which help software developers to develop software systems in high quality, on time, and within budget. We have developed several methods and techniques, such as imprecise requirements analysis and specification technique, High Order Object-oriented Modeling Technique (HOOMT), intelligent software quality function deployment method, and intelligent computational argumentation technique. These methods and techniques have found applications not only in software development, but also in hardware/software co-design and engineering product development.
I have taught CS153: data structure I, CS206: software engineering I, CS301: Software requirements engineering, CS307: software testing and quality assurance, CS308: Object-oriented analysis and design, and CS406: software engineering II.
