Research Interests

My PhD research investigates the evolution of within-species phenotypic divergence, using island populations of the Aegean wall-lizard (Podarcis erhardii) in Greece as a model system. These lizards exhibit striking colour variation between Greek island populations, but little is known about the evolutionary mechanisms underlying this divergence.

The main aim of my research is to explore whether different P. erhardii populations have evolved locally adapted coloration in different island environments, and whether these local adaptations help them hide from predators (camouflage), attract mates or defend territories (visual signalling), or even both.

As humans have very different visual systems to other animals, a key element of my research is to show how lizard colour patterns might be perceived by the actual ‘receivers’ of these visual signals, namely predators (e.g. birds of prey) and their potential mates and rivals.
