My research interests stem from both my academic background and work experience. While I have worked on a broad range of topics including communication systems, my chief research interest is software engineering. In particular, I am interested in software maintenance and evolution, including clone detection and analysis, service oriented architecture, software product lines, source transformation, empirical software engineering and program comprehension. I believe that a computer is a tool to enrich life by advancing business work, scientific research and social fulfillment, interaction and art, and thus I am interested to any software engineering project that makes life easier in a cost effective and predictable manner. My research approach is a blend of theory, experimentation, and design where I strive for creativity, an understanding of theory to guide practical exploration, solid methodology for experimentation and collaboration with experts when working in areas that I am not already familiar with. I believe scalable techniques with formal underpinnings and proper tool support can lead to a significant improvement over state-of-the-art practices.
