I am the Professor of Comparative Palaeobiology at the University of the Witwatersrand, and my area of expertise is dinosaurian evolution. I've worked in China, Mongolia, South Africa and the USA collecting new dinosaur fossils. My current fieldwork is in the South African Karoo basin, where my students, collaborators, and I have been working on figuring out the age and distribution of the dinosaurs that used to live there.
