With a background outside geography, I see the discipline's breadth and potential for inter-disciplinary and collaborative research as one of its great strengths. With a previous life as an engineer, my recent research has been in more technical areas such as spatial modelling, complexity theory and geocomputation. Further, I see developments in all of these fields as holding great potential for considered and critical engagement between the quantitative and other traditions in geography.
You might guess from this that my research interests are broad. On the technical side they include complex modelling techniques such as cellular automata (CA) and agent-based models (ABM). My own research has included exploring the implications of introducing irregularity into cellular automaton models, using graph theory (i.e. network theory). I'm interested in using these types of models in various geographic contexts, especially urban geography. I am also interested in the general dynamic properties of such models and the implications of those for social sciences. I also have interests in visualization, spatial analysis, and gentrification.
