Research

Research interests

In my research I investigate the interplay between the behaviour of individuals and the processes and patterns expressed at the population level. My main line of research is aimed at understanding how inter-individual sexual interactions act as a driving force for social evolution. Using the Trinidadian guppy (Poecilia reticulata) as a model system, I have developed a novel research framework for exploring selection for social traits in the context of sexual conflict (i.e. the conflict of interest between the sexes over reproduction). Specifically, I am examining factors that drive social associations amongst females and how male coercive mating tactics affect female sociality over developmental and evolutionary time. A major component of this work lies in identifying the underlying biological mechanisms driving changes in social behaviour.

Research projects

I am currently taking on PhD and Masters by Research students (funding contingent). Any specific projects are listed below, but you can also get in touch with other project ideas.
