Research Interests
My research activity is now almost non-existent due to the demands of managing HiGHS. Previously, my research work yielded a small number of highly-regarded papers

Biographical Statement
Born in 1964 and educated at King's School Macclesfield (1974-83). Studied Maths at New College Oxford (1984-87) then Numerical Analysis and Optimization at the University of Dundee (1987-90) under the supervision of Roger Fletcher FRS. Having lived with Agnès Guyon since 1989, we married in 2001 and have daughters Lucie and Katya.
Professional Activities
My main professional activity is the development and maintenance of HiGHS, the world's best open-source software linear optimization software.
Previously, I maintained a research interest in developing algorithmic and computational techniques for solving large scale linear programming (LP) problems on both serial and parallel computers. For many years this was focused on the revised simplex method but I have also worked on the development of novel algorithms. A consequential research interest was the application of these techniques in other areas of computational optimization and linear algebra.
