### Biography

Before starting university in Oxford, I worked for 8 months in the Department
of Numerical Analysis and Computing at the National Physical Laboratory
in Teddington. I finished my D.Phil. at Oxford in 1982, having spent one year
in the O.R. Department at Stanford University in California. I then spent three
years as an Assistant Professor in the Department of Combinatorics and
Optimization at the University of Waterloo, Ontario, Canada, before
returning to England and joining
the Numerical Analysis Group in the Computer Science and Systems Division
at AEA Harwell.

I moved with the Group to the Central Computing Department (as it was then)
at RAL in 1990 and have been there almost ever since.
I spent a sabbatical year at CERFACS in Toulouse, France, during 1993.

I am a visiting Professor within the
Department of
Mathematics and Statistics at the University of Edinburgh,
and at the University of Oxford.
I won the Leslie Fox prize in numerical analysis in September 1986, and
the Beale-Orchard-Hays prize for excellence in computational
mathematical programming in August 1994. In May 2009,
I was elected as one of 183 inaugural SIAM Fellows.
I have published two books: the first
on the software package
LANCELOT
in 1992, and the second on
trust-region
methods in 2000. I was editor-in-chief of the
SIAM Journal on Optimization from 2005 until 2010, and
am associate editor for the
ACM Transactions on Mathematical Software,
for the
IMA Journal of Numerical Analysis,
for
Mathematics of Computation,
and for
Mathematical Programming,
and as well as being an Area Editor for
Mathematical Programming Computation.

My research interests are currently
on the theory and practice of optimization methods, on numerical linear
algebra, on large-scale scientific computation, and on the links between
these fields.
My other interests include church-bell
ringing,
hill walking,
messing about on
canals,
mushroom collecting,
and appreciating cask-conditioned
ales of
all varieties. I am a long-suffering supporter of
Tottenham Hotspur FC.

In 2006, I was appointed as Professor of Numerical Optimisation and
Tutorial Fellow of
Exeter College
at the University of Oxford. I returned full-time to RAL in 2008.
I became an STFC Senior Fellow in 2011.
