Profile:
1993 BA (Hons) Natural Sciences, Zoology (University of Cambridge)
1998 PhD, Earth Sciences (University of Cambridge).
1996-1999 Junior Research Fellow. (Trinity College, University of Cambridge).
1999-2003 Lecturer in Animal Diversity (University of Oxford).
2003-present Researcher - dinosaurs and fossil reptiles (The Natural History Museum, London).

My research is centred on the taxonomy, systematics, functional morphology and macroevolution of dinosaurs and other extinct amniotes. Research is concentrated in three main areas:

• Pattern and process in macroevolution. Controls on dinosaur and pterosaur diversity through time and space, including the influence of the rock record on modelled diversity patterns; multidisciplinary testing of plant–dinosaur co-evolutionary scenarios (using a novel application of Geographical Information Systems); clade-clade interactions through time; correlated progression; and the possible effects of changing atmospheric CO2 concentrations on the evolution of Mesozoic terrestrial ecosystems.
• Functional morphology, palaeobiology and palaeoecology of sauropodomorph and ornithischian dinosaurs, relating primarily to feeding mechanisms. A second project that is currently underway, in conjunction with Dr Susannah Maidment, involves evaluating why some ornithischians become secondarily quadrupedal.
• Taxonomic, systematic and faunal revisions of dinosaurs from the Middle Jurassic and Early Cretaceous of the UK, the Lower Jurassic and Early Cretaceous of the People’s Republic of China, the Lower Cretaceous of Australia and the Lower Jurassic of South Africa and Lesotho. In addition, other projects that I am involved in concern varanid lizards from the Pleistocene of Australia, a stem turtle from the Isle of Skye and marine reptiles from the British Lower Cretaceous.
