I am currently a member of the Theoretical Physics Group and, in addition, a member of the cross-disciplinary Centre for Complexity Science, My current research follows two broad, but very different, paths that reflect this duality: quantum field theory and complex spatial networks.
My work on complexity, which is currently my major activity, is frequently in collaboration with Tim Evans of the Theoretical Physics Group and students at the Centre for Complexity Science and addresses applications and issues in modelling archaeological networks. In this I am part of a mainly European grouping incorporating computer scientists and archaeologists (in particular, at this moment, ETH Zurich, U. of Cologne, U. of Kiel, U. of Kiev, U. of Paris 1, U. of Toronto). Such modelling is strongly influenced by that used in contemporary urban planning for transport, commuting and city development and by ecologists. Like astrophysics, archaeology is intrinsically Bayesian (although data is very poor) and an information-theoretic approach, e.g. MaxEnt,, can be very productive. I have been particularly concerned with the limitations of modelling e.g. the role of contingency.
Whereas quantum field theory papers can be found easily on the arXiv, in archaeology no such archiving exits. My papers occur equally in journals (e.g. Antiquity) and monographs (sometimes published years after the event). Tim Evans' web page gives access to some of them.
