### Other projects

Dr Jonathan Thompson has also completed projects with several companies including WH Smiths, John Menzies and the International Rugby Board. He is an active researcher in the areas of heuristics, and particularly in timetabling, manpower planning and scheduling. He has recently extended his research to vehicle routing problems and in particular, real time routing. He is currently a member of the organising committee of the OR49 conference held in Edinburgh this September. He has organised several streams on scheduling at OR conferences. He is on the Editorial Board of the International Journal of Operational Research and on the Programme Committee for several conferences such as GECCO, PPSN and PATAT.
