Title: Exact asymptotic analysis for spatially extended stochastic 
population dynamics.

Speaker: Stephen Cornell, reader in mathematical ecology at the 
University of Leeds, UK.  I have a background in nonequilibrium 
statistical physics, but for the past 10 years I have been working in 
theoretical ecology.  I am particularly interested in methods for 
calculating the properties of populations that interact spatially. This 
talk will focus on a perturbative technique that I have been developing 
with Otso Ovaskainen, where the length scale of interactions is assumed 
sufficiently large (relative to the distance between neighbours) that 
the dynamics is `close' to mean-field.
