I am interested in animal behaviour in an evolutionary ecological framework. In my research I ask fundamental questions about the emergence, maintenance and consequences of social structure in animal populations. I typically track animals with GPS loggers, which provides deep insight into animals' spatial behaviour. My research questions sit at the interface of three exciting and growing research areas, and specifically address the complex interconnection between them:
1) Animal social networks. Which factors drive animal social structure, and collective behaviour, and what are the consequences for health and fitness?
2) Movement ecology. Social structure can emerge as a consequence of animal movement and space use. I investigate how movement decisions at the individual and group level affect the probability of interacting with other conspecifics and how this ultimately leads to the emergence of social structure.
3) Disease ecology. How do spatial and social interactions predict pathogen transmission through populations?
