研究领域

My research focuses on two broad areas: the evolution of aggregation as an anti-predator behaviour, the role of the physical and social environment on foraging, mating and social decisions. The first theme explores why animals live in groups (flocks, shoals and herds), particularly as a response to predation risk, and what drives the patterns of grouping that we see, such as which group an animal chooses to join, and the risk that it experiences by choosing one group over another. The second theme explores how animals respond to the environment in which they live. This includes the physical environment, such as the distribution of resources, water flow or turbidity, and the social environment: the behaviour of other individuals around them. Under this theme, we are particularly interested in how experience of a particular environment shapes behavioural responses, and the effects of environmental change on behaviour. We explore these questions using small fish and invertebrates (we are currently working on guppies, sticklebacks and Daphnia), and computer models.
