Senior Lecturer and
Royal Society Industry Fellow

Stefan Marr I am working at the School of Computing at the University of Kent. My work focuses on programming language implementation techniques, complex concurrent systems, and tooling.

Much of work revolves around making interpreters faster, detecting and preventing concurrency bugs at run time, and use modern language runtime systems to provide programmers with better tooling.

Oct 22, 2016: Language Research with Truffle at the SPLASH'16 Conference

Next weekend starts one of the major conferences of the programming languages research community. The conference hosts many events including our Meta’16 workshop on Metaprogramming, SPLASH-I with research and industry talks, the Dynamic Languages Symposium, and the OOPSLA research track.
Sep 17, 2014: Fork/Join Parallelism in the Wild: Documenting Patterns and Anti-Patterns in Java Programs using the Fork/Join Framework

Parallel programming is frequently claimed to be hard and all kind of approaches have been proposed to solve the complexity issues. The Fork/Join programming style introduced with Cilk enables the parallel decomposition of problems in a recursive divide-and-conquer style, and on the surface looks very simple with its minimalistic approach of having a fork and a join language construct. But is it actually simple to use? To find out, Mattias started to dig through the Java open source projects on GitHub and tried to identify common patterns. Next week, he will present our findings at PPPJ’14.
