I am a Professor in the
Department of Mathematics and Statistics,
University of Reading, and an honorary professor
in the UCL Maths Department.
I am always interested to hear from candidates for a PhD or a postdoctoral position. Examples of some old and new research are below and elsewhere on this website.
