I am currently a Research Leader in Life Sciences at the Natural History Museum, London and Honorary Professor in Palaeobiology in the Department of Genetics, Evolution, and Environment at University College London.
Outside of the NHM, I serve as Member-at-Large on the Executive Committee for the Society of Vertebrate Palaeontology. I am also a fellow and member of the programmes committee of the Linnean Society of London. I am a member of the UK Natural Environment Research Council (NERC) Peer Review College and serve on the editorial boards for Biology Letters, Evolution Letters, Palaeobiology, and Palaeontology.
My main research interests are in vertebrate evolution and development, especially using 3D morphometric methods to incorporate data from embryos to fossils to test genetic and developmental hypotheses of modularity and morphological diversity and reconstruct macroevolutionary patterns through deep time. I have previously focused on skull evolution in carnivorans and the marsupial-placental dichotomy, but lately I have been researching these topics across other clades and skeletal systems, with an ERC-funded project on modularity and morphological diversification across tetrapods and a recently-completed Leverhulme Trust-funded project on cat postcranial mechanics and evolutionary modularity.
I am also currently working on the relationships and paleobiogeography of Mesozoic and early Cenozoic mammals, particularly focusing on Gondwanan eutherians, with a recently-completed Leverhulme Trust-funded project uniting genomics and fossils to elucidate early placental evolution. As part of this work, I am involved in a Leverhulme Trust-funded project on the evolution of latitudinal biodiversity gradients in Cretaceous vertebrates.
I currently conduct fieldwork in the Cretaceous and Palaeogene of India and Argentina, but have previously been involved in fieldwork in Svalbard, Peru, Chile, Madagascar, and the United States. I have also conducted palaeoecological research on Triassic amniotes and Eocene whales using dental microwear and stable isotopes.
