My research focus is on programming language implementation and performance analysis. My interests include garbage collection, just-in-time compilation, computer architecture, operating systems, and security. I am a strong believer in shared research infrastructure, leading the DaCapo benchmark project and the MMTk memory management framework.
Garbage collection is a major focus of my research. I am particularly interested in novel garbage collection algorithms, the detailed performance analysis of garbage collection, the design of novel high performance garbage collection mechanisms, and the implementation and software engineering of high performance garbage collectors. I am also interested in architectural support for garage collection. I lead the development of the MMTk memory management framework.
The context for most of my research has been language implementation. I am interested in the software engineering of high performance language runtimes, and also the social dimension of successfully creating large software artefacts within the research community.
I have a major interest in performance analysis. I am interested in performance analysis techniques, benchmark suites, and sound methodology. I lead the development of the DaCapo benchmark suite.
I am a professor of computer science at the Australian National University. My primary research focus is on programming language implementation. I have published in venues that specialize in programming languages, memory management, operating systems, virtual machines, computer architecture, compilers, performance analysis and software engineering. I am a Fellow of the ACM.
