Summary

 

Summary

I'm a software developer and researcher at NVIDIA, and was previously an Assistant Professor at Durham University in the Department of Computer Science and a PDRA at Imperial working with David Ham and Paul KellyMy research is in high performance computing and computational mathematics. Much of my recent focus has been in the development of compilers and software abstractions for the development of numerical models implemented using the finite element method. This research is concretely realised in the open source Firedrake project. I am particularly interested in preconditioning techniques for challenging problems in computational and atmospheric fluid dynamics.
