Ecology, evolution and conservation

Research Interests

ecology, evolution, behaviour, conservation, environmental change fish, birds, mammals

My research focuses on understanding the complex relationships between environmental change, animal behaviour and evolutionary processes. Specifically, I am interested in the impact of environmental change on interspecific interactions, and the influence of social and sexual selection on trait evolution. To explore these issues I study a variety of vertebrate taxa (birds, fish, mammals), using laboratory, field and computer simulation-based techniques. My background is in behavioural ecology, and I also use tools from conservation biology, phylogenetics and ecological modelling.
