His interdisciplinary research program aims to untangle the roots of early animal evolution in order to obtain a better understanding of the origins and relationships of the major animal phyla. In particular, his research focuses on detailed exploration of the Cambrian Radiation of animal life which heralds the emergence and rapid diversification of the major animal body plans and the birth of animal-based ecosystems. He is a currently a member of the research team excavating and describing the treasure trove of exceptionally preserved fossils, including rare soft-bodied animals, from the Emu Bay Shale on Kangaroo Island, South Australia. Professor Brock leads a very strong, vibrant and effective Palaeobiology Research Lab located within the Genes to Geosciences Research Centre in the Department of Biological Sciences.
