My first degree was an M.A. in Mathematics and Natural Philosophy at Edinburgh, after which I obtained my Ph. D. from Cambridge University.
My research interests are mainly in the phenomenology of the elementary particles. For some time I worked on the analysis of pion-nucleon interactions, but then became interested in various aspects of symmetry breaking. In recent years I have been working on electroweak symmetry breaking, in models with more than one Higgs doublet. I am interested in electroweak baryogenesis, exploring the possible relationship between the matter-antimatter asymmetry of the Universe and the masses of Higgs particles which current and future accelerators hope to find. More specifically I am interested in the NMSSM and spontaneous CP violation
I have now retired from lecturing, and am an Honorary Research Fellow. In recent years, I have been running informal tutorials on Quantum Field Theory.
