Research Interests
My long-term research aims are focussed on the understanding of the origination and early evolution of animal-based ecosystems, their impact and relationships to climate and environments and their properties such as biodiversity and biogeography. Particular research focus areas include:
•The Cambrian Explosion
•The Great Ordovician Biodiversification Event
•End Ordovician extinction event
•Classification of the phylum Brachiopoda.
