Research

My research interests are in the theory of Markov decision processes, game theory and reinforcement learning, and applications of these areas to problems in queuing theory and behavioural ecology.

I am a member of the Statistics Group in the Department of Mathematics and I am involved in several of the group research themes, particularly Applied probability, Behavioural biology and Optimisation under uncertainty

I am also part of the University's Centre for Behavioural Biology.
