Personal profile

Research interests

My research interests are in numerical linear algebra, data assimilation and inverse problems.

In particular I am interested in iterative methods for eigenvalue problems and linear systems, Krylov subspace methods, matrix theory and applications.

I am a member of the Numerical Analysis Group in Bath and if you want to find out more about myself, my current research, my publications and other work I do at Bath (and beyond), please have a look at my homepage.
