Profile
Bill Jackson received his PhD from the University of Waterloo in Canada in 1978 and then returned to England as a postdoctoral research fellow at the University of Reading. He has lectured at the University of London since 1980 and is currently head of the Combinatorics Research Group at Queen Mary. He has served on the British Combinatorial Committee and the editorial board of the Journal of Combinatorial Theory, Series B. He is a member of the Egerváry Research Group on Combinatorial Optimisation at Eötvös University in Budapest. His research interests are in Graph Theory, Matroid Theory and Discrete Geometry.
