Biography

I am a vertebrate palaeontologist interested in the evolutionary origins of birds and other tetrapod groups. My research focuses on using fossils to understand how, where, and when modern vertebrate biodiversity arose. I am originally from Calgary, Alberta, studied Zoology at the University of British Columbia, and received a PhD in Geology and Geophysics from Yale University in 2017.

Research

Work in my lab aims to decipher the origins of modern avian biodiversity, using fossil, anatomical, and molecular data, although we have deep interests in evolutionary questions across the vertebrate tree of life. In 2020 we revealed the discovery of the "Wonderchicken", Asteriornis, the oldest-known modern bird fossil and an early relative of the group that gave rise to living chickens and ducks. Major themes of our research include clarifying how birds survived and diversified following the mass extinction of non-avian dinosaurs, studying the evolutionary histories of major bird groups, and understanding the evolutionary origins of distinctive biological features such as the modern bird skull.
