Research

My current research interests include numerical analysis, computational methods for PDEs, scientific computing and parallel algorithms, numerical modelling of microstructure, computational methods in materials science and statistical physics, non-linear elasticity and calculus of variations, non-linear PDEs, and bifurcation problems.
