Current funded research programme

Anomalous diffusion via self-interaction and reflection, funded by the EPSRC, runs 2022-2026. This is a joint project between Durham (EP/W00657X/1, £448,461) and Warwick (EP/W006227/1, £457,337).

Research Summary

My research is in probability theory and its applications. My interests include random spatial models and stochastic processes inspired by physics or other applications. Some of my recent work has been on random walks, random spatial graphs, processes in random media, and interacting particle systems. For some more details about some of my research and publications, see here.
