My interest is the role individual behaviour plays in ecological processes, in particular how animals trade-off foraging reward and predation risk as well as how animals move through the landscape to maximize their fitness.
- Predation risk sensitive foraging in birds
- Optimal search strategies using genetic algorithms and Levy flights
- Urban wildlife road crossing behaviour
