Bio:

My broad research goal is to help developers build more efficient software systems more efficiently. I tend to have a hard time focusing on a single research topic. In the past, I’ve worked on a wide variety of subjects, such as program transformation systems, formal modeling of exception propagation (in sequential and concurrent systems), failure detection in distributed systems, aspect-oriented programming, and design diversity in service-oriented architectures.

Nowadays, I’m more interested in the energy efficiency of software systems, in particular, how exploiting off-the-shelf design diversity combined with software refactoring can be a cheap way of saving energy. I’m also puzzled by how developers employ existing constructs for concurrency control and for managing parallel execution and how these constructs impact performance, energy efficiency, and maintainability. Lately, I’ve also developed a healthy interest in code reviews, code readability, and on how we can make the review process more efficient and less painful for reviewers and patch set submitters. Furthermore, my heart seems to have a soft spot for exception handling and I just can’t let go of it.
