I am interested broadly in animal social behaviour and evolutionary ecology, focusing on interactions between the sexes and also between predators and prey.
My current research has two main focuses. In the first I look at how the social context, such as the number of mate options available, influences the strength of sexual selection and mating preferences. I have used the seed bug Lygaeus equestris to test whether both pre- and post-copulatory sexual selection on morphological traits is influenced by the number of mate options individuals are presented with. I have also used meta analysis to examine this pattern across species.
My second focus is the evolution of animal genitalia. I have used experimental manipulation, selection analysis and 3D imaging techniques to try to determine the function of the elongate male genitalia in Lygaeus simulans, and the mechanisms that have led to its evolution.
