Reader in the Optimization and OR group in the School of Mathematics
My main research interest is 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, recently, I have switched my attention to work which will lead to the development of novel algorithms. A consequential research interest is the application of these techniques in other areas of computational optimization and linear algebra.
In collaboration with current and former PhD students, Ivet Galabova, Michael Feldmeier and Qi Huangfu, I am managing the development of the high performance open-source software linear optimization software HiGHS.
