I am an EPSRC funded PhD student, studying Lévy processes. I am interested in fractal properties, complex analytical techniques, and large deviations behaviour related to Lévy processes.

Spectra of indefinite self-adjoint pencils: A generalised spectral problem $(A-\lambda B)u=0$ with self-adjoint operator coefficients $A,B$ acting in some Hilbert space, will have a purely real spectrum if any of the operators $A,B$ is sign-definite, i.e. if all of the eigenvalues of $A$ or $B$ have the same sign, either positive or negative. If, however, both coefficients are indefinite, some complex eigenvalues may appear, and the spectral picture is much more complicated. The applications include some large matrix problems with very interesting behaviour, still not understood fully, and the spectral problems arising in the study of new graphene materials.

I'm a PhD student studying numerical analysis, in particular I'm interested in the application of discontinuous Galerkin methods to geophysical problems.

I am Professor of Applied Mathematics and currently President of the SIAM UKIE Section. I hold a joint appointment at Reading in the Departments of Mathematics and Meteorology and am a Principal Investigator of the National Centre for Earth Observation. My primary research is in numerical analysis with applications in numerical linear algebra, control theory, and data assimilation. Data assimilation is key to the accurate prediction of evolving dynamical systems. All my favourite theoretical and numerical techniques are needed in this field and there are many open problems yet to be solved.

I am an EPSRC funded student and I work in Data Assimilation looking at how introducing correlated errors impacts convergence in variational assimilation. This involves numerical linear algebra, small scale numerical tests and operational scale experiments on the Met Office system.
