I am a palaeontologist interested in studying functional morphology and biomechanics with an eye towards overlooked taxa and anatomical elements. At the moment my research focuses on evolutionary trends in the tails of non-mammalian synapsids, and how these variable structures may have been used in locomotion. My work involves CT scanning and developing 3D multi-element models, as well as statistical analyses using R and MATLAB. My previous research has examined the ecology and evolutionary history of mammals, both extant and extinct, with a particular focus on comparing the locomotory ecology of marsupials and placental mammals, as well as the morphology of multituberculate mandibles.
