Professor

Profile

Professor Letchford is recognised internationally for his work on optimisation. He has published over 55 papers in highly-ranked journals, and more than 10 chapters in edited books, many of which were co-authored with prominent overseas researchers. He has been on the editorial boards of 6 journals: Computational Optimization and Applications, Discrete Optimization, EURO Journal of Computational Optimization, Mathematical Programming, Mathematical Programming Computation and Operations Research. He has given over 50 presentations at international conferences, including 8 plenaries, and over 30 invited seminars in Europe and the US. He has also been on the programme committees of 10 international conferences.

In 2006, he became the recipient of a prestigious IBM Faculty Award. In the same year, he was awarded a 5-year EPSRC Advanced Research Fellowship. In 2009, he became a Fellow of the Operational Research Society. In 2013, he was the principal organiser of a 4-week residential programme on optimisation that took place at the Isaac Newton Institute in Cambridge. He directed the optimisation cluster of the LANCS Initiative from 2008 to 2013, and is currently directing NATCOR, the national taught course centre in Operational Research.
