I joined the University of Sheffield on October 1st 2010. Previously I was in the Department of Computer Science, University of Bristol. This is a temporary website, based on my old Bristol homepage, which I plan to upgrade in due course. Links may currently take you to old pages at the Department of Computer Science, University of Bristol.
Please visit the new lab pages for the Behavioural and Evolutionary Theory lab for more up-to-date information.
Research Interests: Biologically-Inspired Algorithms, Cognitive Behaviour, Complex Adaptive Systems, Decision Theory, Evolutionary Theory, Mathematical Biology, Social Insect Behaviour
