I no longer have teaching or research duties in the School, where I worked from 1976-2009. I was Professor of Applied Mathematics from 1986-2009, Head of the (then) Department of Computer Science 1999-2002, Vice-Principal for Science and Engineering 2002-5, and held various other roles in the School and (as it then was) College. See my personal web page for details. I was Director of the Heilbronn Instutute for Mathematical Research in Bristol 2009-2012, and Secretary (1995-2010) and President (2010-2013) of the International Society on General Relativity and Gravitation. I continue to research, edit and write in my fields of interest, and interact with members of the Geometry and Analysis group in the School and the Cosmology group in the School of Physics and Astronomy.
