Personal statement

I work with Prof Victorita Dolean as a research associate in scientific computing of wave scattering problems and applications. We are interested in domain decomposition methods for solving frequency domain wave propagation problems, such as those modelled by the Helmholtz or time-harmonic Maxwell equations. These models have applications in electromagnetics, geophysics and medical imaging, amongst others.

Previously I completed my doctorate under Prof Andy Wathen in collaboration with the US Army Coastal and Hydraulics Laboratory where I worked on scalable two-phase flow solvers, in particular focusing on preconditioning for variable coefficient Navier–Stokes equations.

Research interests

My wider interests lie in computational methods for solving challenging problems rooted in applications, typically stemming from PDE models which are discretised by finite elements, and developing novel algorithms that are efficient and robust to model parameters. My focus if primarily on the numerical linear algebra tools that are at the centre of effective computational simulations.
