Stefan Marr, Researcher and Lecturer

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

In my dissertation, I proposed an ownership-based metaobject protocol as a unifying substrate for concurrency support in multi-language VMs.

Currently, I am working on combining concurrency models in a safe manner and to enable developers to make sense of complex concurrent programs with appropriate tools.

Oct 15, 2017 Debugging Concurrency Is Hard, but We Can Do Something About It!
When we have to debug applications that use concurrency, perhaps written in Java, all we get from the debugger is a list of threads, perhaps some information about held locks, and the ability to step through each thread separately.
Oct 25, 2016 Cross-Language Compiler Benchmarking: Are We Fast Yet?
Research on programming languages is often more fun when we can use our own languages. However, for research on performance optimizations that can be a trap. In the end, we need to argue that what we did is comparable to state-of-the-art language implementations. Ideally, we are able to show that our own little language is not just a research toy, but that it is, at least performance-wise, competitive with for instance Java or JavaScript VMs.

The second conference day was unfortunately full of “conflicts of interest”… It was pretty hard to choose between all the talks on the schedule.
