I am now retired, but have an honorary position as a Distinguished Research Fellow in the theoretical physics group 

When still lecturing I taught the MSc courses Lorentz and Poincaré Groups, and sections on Lattice Gauge Theory and Anomalies and the Renormalization Group within the Advanced Field Theory Course. All of these have fully-typed up notes.
I have written a book on group theory entitled Groups, Representations and Physics, published by IOP (now Taylor and Francis). The following image is the cover picture, illustrating the relation between the groups SU(2) and SO(3). The second edition was published in 1998 and contains an additional chapter on the Cartan-Weyl-Dynkin approach to general Lie algebras.

My research is on non-perturbative methods in quantum field theory, and the properties of non-Hermitian, but PT-symmetric, Hamiltonians in quantum mechanics and quantum field theory. The ideas developed there have recently found very important applications in classical optics.
