About

David Bryant is a world leader in the development of mathematical tools for inferring evolutionary relationships among biological organisms. He has made significant theoretical and practical contributions to phylogenetics — the field of biology studying the reconstruction of evolutionary history. His research has been highly cited and applied to a diverse range of different areas, including early bacterial evolution, plant ecology, rapid identification of pathogens and even the origins of the fairy tales! He was joint winner of the 2016 New Zealand Mathematics Society Research Award.

Prior to coming to Otago, David was an associate professor at McGill University, Montreal, and then at the University of Auckland.
