I lead the Software Performance Optimisation group within the Department of Computing, which in turn is part of the Programming Languages and Systems research section. I am co-Director of Imperial's Centre for Computational Methods in Science and Engineering, and also Director of Industrial Liaison for our Centre for Doctoral Training in High-performance Embedded and Distributed Systems (HiPEDS).

While I have worked in many areas of computer systems, the core of my current work is compiler technology. Much of my work aims to push the frontiers of compiler research through moving up the "food chain" - exploiting properties and opportunities special to particular classes of application. This has led me to engage deeply with collaborators in finite element methods, and computer vision.
