I am a PhD candidate on the Oxford NERC DTP in the Department of Zoology and am currently conducting research on the evolution of reproductive modes in reptiles. In particular, I want to know why all birds lay eggs, as opposed to other reptiles that frequently utilise life birth as an alternative strategy.

My main research interests are animal physiology and large-scale evolutionary transitions of anatomy in reptiles. Specifically, including the reptilian fossil record and palaeontological methods.

I have previously investigated the evolution of feathers in non-avian (not birds) dinosaurs, exploring how shared traits of bird and dinosaur colour vision influenced selective pressures that favoured the evolution of elaborate colour ornamentation by means of feathers, as opposed to fur.
