I am a Professor in the department of Earth Science and Engineering at Imperial College London (ICL), UK. I am also head of the Applied Computation and Modelling Group (AMCG), which is the largest department research group at ICL and comprises of about 70 research active scientists. AMCG specialises in the development and application of innovative and world leading modelling techniques for earth, engineering and biomedical sciences. The group has core research interests in numerical methods for ocean, atmosphere and climate systems, engineering fluids including multiphase flows, neutral particle radiation transport, coupled fluids-solids modelling with discrete element methods, turbulence modelling, inversion methods, imaging, and impact cratering. I was honoured by Imperial College London by winning its Research Excellence Award in 2010, in recognition my world-leading research.

I have authored over 121 journal publications (which have so far received 603 citations), 2 book chapters, 1 patent, graduated 30 PhD students and completed 40 industry and research council grants.

The ability to preserve conservation properties with mesh adaptivity was a major unsolved issue for the further development of adaptive mesh algorithms in earth system science simulation. This paper was the first to demonstrate a solution to this problem. The lead author was my PhD student who has been awarded/shortlisted for several prizes for this work.

Data assimilation (DA) techniques are extremely valuable in improving the predictability of modelling. However, application of efficient DA approaches are often hampered by the complex code required and high computational costs. A newly developed data assimilation formulation was developed and described in this paper to dramatically reduce the code complexity and increase maintainability. This provides a very simple approach for forming the adjoint of discrete forward models using a graph colouring approach combined with a perturbation method. Importantly, the adjoint is automatically updated as the forward code continues to be developed.
