Personal profile

Research interests

My research is in probability theory. Much of my work is motivated by population genetics: I study the long-term behaviour of stochastic processes which model a spatially structured population. Often this involves looking at branching processes or interacting particle systems. I also use probabilistic techniques to study partial differential equations.
