My research has always focussed on particle physics phenomenology, which is the
place where theory and experiment meet, in order to test
the former and understand the latter.
From 1995-2007, my main research interest was in diffractive photoprocesses,
and was stimulated by the continuing flood of experimental
data on this subject, especially from the HERA facility in Hamburg.
To understand why such processes have stimulated so much experimental and
theoretical interest, see my talk
"Introduction to diffractive photoprocesses" at Photon2000.
My own research concentrated mainly on the QCD dipole model of diffraction,
which gives a unified understanding of many different diffractive processes,
and provides a framework for investigating fundamental features of QCD,
like gluon saturation. For a brief
survey of the dipole picture, see my talk at "Diffraction 2006."

I formally retired from the University in September 2009, but still do
occasional teaching and share an office. Prior to that, I was
responsible for the Joint Honours programme in Mathematics and Physics;
and taught several different courses in each of the following
areas: mathematics; quantum mechanics; quantum field theory; particle
physics; solid state physics and statistical physics.
