Yes, I know quite a few. In computational genomics in the south-east UK there's us (University of Cambridge Plant Sciences), Queen Mary University (Yannick Wurm's group), and The Sainsbury Lab at the John Innes Centre in Norwich (Dan Maclean's lab).

In-progress code for my PhD is mostly on Github: http://github.com/Blahah
