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
in the School of Mathematics
and I am involved in several of the group research themes, particularly
Behavioural biology and
Optimisation under uncertainty
