Research Interests

Numerical analysis, optimal control of PDEs, inverse problems.

My current research is on the analysis and numerical analysis of inverse and optimal control problems with PDE and variational inequality constraints. I have worked on analysing algorithms for a phase field approach to binary image recovery, and implemented them in DUNE-FEM. More recently I have worked on mesh adaptivity for optimal control of variational inequalities, and on proving convergence for finite element discretisations of problems related to the optimal control of PDEs with sparse data.
