Research Interests My research interests range from programming languages and software engineering to operating systems, algorithms, and performance evaluation. I am fascinated by many different research topics combining intellectually challenging problems and practical applicability. My primary research focus has been the area of software generators. Software generators are compilers for domain-specific languages. This direction of work has led me to explore various issues in extensible programming languages and object-oriented programming. Lately I have also worked on virtual memory management (replacement algorithms and compressed virtual memory) as well as techniques for  reduction (i.e., compression) of program traces used in virtual memory simulations. This research was performed in collaboration with Scott Kaplan and Paul Wilson.

I am a member of the Software Systems Generator Research Group at UT, working with Don Batory. Support for my work is provided by a research agreement with Microsoft Research. I have been actively involved in the Intentional Programming (IP) project at Microsoft Research (both in the course of my research and during internships in the summers of 1995, 1996, and 1997).
