Research: Palaeobiology, phylogeny and development of Palaeozoic arthropods

My main academic interests include the palaeobiology and evolution of invertebrates, particularly arthropods, during the Cambrian Explosion some 530 million years ago. My PhD research consists on investigating aspects of the fundamental body organization of some of the oldest arthropod groups in the fossil record, such as trilobites,by making comparisons with the developmental biology of extant representatives. I am also interested in the phylogeny and diversity of various lower Palaeozoic arthropod groups that are mainly known from sites of exceptional preservation, like the famous lower Cambrian Chengjiang (South China) and middle Cambrian Burgess Shale (British Columbia), and to a lesser degree from other localities in the world, such as the Ordovician of the Czech Republic, and upper Cambrian of North America and Tasmania.
