I am currently undertaking a PhD with the Archosauromorph Research Group investigating morphological disparity, taxonomic diversity, body size and other aspects of the evolutionary dynamics of early archosauromorphs. I am also involved in reassessing the monophyly, anatomy and distribution of the early archosauromorph group 'Euparkeriidae', with a current focus on Euparkeria capensis.
