Summary

Prof. Ham's research interests centre on the development and composition of high level abstractions for scientific computation, particularly geophysical fluids. His interests span computational and computer science and include both new numerical schemes and novel approaches to their implementation.

Prof. Ham's most recent work is on differentiable abstractions for the generation of finite element models. He leads the Firedrake project and is an author of the dolfin-adjoint automated inverse simulation framework. The latter work was awarded the 2015 Wilkinson Prize for Numerical Software.
