My research interests lie in the general field of sexual selection, with particular focus on postcopulatory sexual selection. I mainly use the guppy (Poecilia reticulata) as a model species to study sperm competition dynamics, cryptic female choice and the evolutionary consequences of sexual conflict. My current research (funded by Marie Curie International Outgoing fellowship) focuses on the role of sperm ageing in the maintenance of genetic variance in traits associated with reproductive success.
