My research concerns the evolution of modern vertebrate anatomy. I use the fossil record of early vertebrates from the Palaeozoic Era (approx. 540 to 250 million years ago) to reconstruct the evolutionary assembly of major features of vertebrate anatomy, such as the skull and jaws, paired appendages, and hard tissues.
