I am interested in the evolution of life across the Proterozoic–Phanerozoic transition. My work reveals the fine-scale anatomy preserved in exceptional fossils, and explores the implications for animal phylogeny, macroevolution, and macroecology.

I am particularly interested in the origins and early evolution of crustaceans, sponges and ecdysozoan worms, and in using small carbonaceous fossils (SCFs) to obtain a higher-resolution picture of broader-scale patterns and processes.
