I am interested in understanding and predicting the behaviour of complicated random events and processes, in particular when there are network or spatial structures involved. Most of my work is connected to the idea of emergence: how large scale order can be created out of the random interactions of individual particles or organisms. The problems I work on come from a wide range of sources, including:

- Random matrix theory
- Networks and epidemics
- Ecology and evolution
- Stochastic processes

- Fitness differences suppress the number of mating types in evolving isogamous species
