Research

My primary research interests can be found in the areas of dynamic program analysis, and software performance evaluation and modeling. While the two areas may seem rather broad and too far apart, the topics that I work make them much closer. After all, software performance is about observing what applications do and measuring how fast they do it (easily, accurately, promptly — pick two), while dynamic program analysis is about … observing and analyzing what applications do.

With respect to dynamic program analysis, I am mostly concerned about analysis composition, program instrumentation, profiling accuracy, and observability of program execution on modern managed platorms. With respect to software performance, I mostly focus on methods and tools for increasing performance awareness during software project development. This calls for automatic performance evaluation during development, automating performance change detection, and testable documentation of assumptions about program performance.

I am also generally interested in object-oriented programming and design, programming languages and practices, operating systems, computer architectures, and other systems-related topics. I teach or have taught courses on some of those topics.
