My current research interests revolve around the mathematical modelling of complex social and economic systems. The systems can take a variety of forms, from retail to riots and terrorism, but all with mathematical pattens that emerge and evolve in space and time.

In a past life I was a fluid dynamicist and my PhD thesis from 2011 can be downloaded as a pdf here, or purchased as a book here. Feel free to have a look. It's a rather delightful romp through the two-dimensional Navier Stokes equations, even if I do say so myself. 

And just because I find it useful to refer back to, here is the derivation of the entropy-maximising singly constrained spatial interaction model.  (Oh. I was being sarcastic when I chose the title of the pdf..)
