My research is focused on spectral theory for unbounded operators, with applications to partial differential equations, semigroup theory and mathematical physics.

My most recent work is about the spectrum of a linearised Navier-Stokes operator via higher order block numerical range techniques and the self-adjoint theory of operators in Krein spaces. At the moment I am mainly focused on developing and applying spectral theory tools to non-self-adjoint operators.

Other personal interests are: dependence of the spectrum on domain perturbations, asymptotic analysis and homogenisation theory, eigenvalue problems with spectral parameter on the boundary condition, overdetermined spectral problems, geometric aspects of quasilinear eigenvalue problems.
