My research focuses on morphological transformation during major diversification and evolutionary events and the mechanisms that underlie them. I focus mainly on the origins of the gnathostome body plan, the fish-tetrapod transition as well as the diversification of the first tetrapods and the major groups of amphibians. I use morphology taken in a phylogenetic framework both from fossils and extant forms as a starting point for my studies encompassing paleontology, developmental biology and genetics in order to provide more information about the origin and evolution of a particular morphology.
