RESEARCH
I investigate software engineering in tasks such as evolution, reverse engineering, transformation, maintenance, and reengineering. I focus on designing useful tools that capture and exploit software understanding.
Most recently, I developed and evaluated representations and tools that capture functional intentions and their implementation at many semantic levels, e.g. requirements, architecture, code, knowledge, and process. My dissertation research produced a practical automatic program understander, used it for quality automatic Cobol restructuring, and presented performance models, measures, and results. (Selected publications shown.)
Senior Research Associate, Visiting Scholar, with B. Chandrasekaran, Laboratory for Artificial Intelligence Research, Ohio State University (DARPA contract, "Functional Representation of Software Systems") (1994-1998)
Developed the use of Functional Representation to capture software understanding. Showed how this benefits tools and tasks such as design, debugging, and modification. Represented hierarchical understandings of executable architectures, legacy code, reengineering processes, programming knowledge etc. Made prototype tool for question answering and automatic explanation using these representations. Showed how Functional Representation formalizes and enhances existing programming plan representations.

Research Assistant, Artificial Intelligence Lab, University of Texas at Austin, supervisor B. Kuipers. (1987-1991)
Developed practical automatic program understander that recognizes control concepts in legacy programs (UNPROG). Demonstrated quality Cobol restructuring using recognized concepts. Created models and measures of automatic program understanding. Produced empirical results characterizing UNPROG performance and program conceptual content and implementation.
