研究领域
My current research focuses on early gnathostome evolution, in particular the origins of the earliest osteichthyans. I am at present focused on the description of new taxa of Devonian fishes from Australia and Silurian placoderms from Yunnan (in collaboration with the Institute of Vertebrate Palaeontology and Palaeoanthropology, Beijing). Notable recent work includes the most primitive jawed vertebrate (Entelognathus) with a modern complement of dermal cranial and gnathal bones, the presence of a dermal pelvic girdle in the earliest bony fishes and antiarch placoderms (a discovery featured in the TV documentary The Rise of Animals presented by David Attenborough), the largest Silurian vertebrate (Megamastax) and the description of new Devonian actinopterygians from Australia and Antarctica. Additionally, I have contributed to research on Mesozoic marine reptiles including Cretaceous ichthyosaurs from Western Australia and trackways from the Triassic of China that represent the first physical record of sauropterygian locomotion. I am also a professional scientific illustrator who has contributed artwork to a wide variety of journals, books and television programs
