Research

Research in our lab is guided by an interest in the evolution of birds and other vertebrates, and a conviction that combining insights from the fossil record and living species will help unravel the mysteries of vertebrate evolution.

Origins of modern bird characteristics

How did key avian features like feathers, flight, enlarged brains, a toothless beak, warm-bloodedness, and even present-day geographic distributions arise? We are interested in applying cutting-edge approaches to these classic macroevolutionary questions.

Comparative vertebrate anatomy

Imaging advances have revolutionised palaeobiology. We apply high resolution visualisation methods to study the evolution of form and function in several vertebrate groups.

Phylogeny and divergence times of birds and other vertebrates

We try to unravel avian phylogenetic interrelationships, and attempt to understand where key fossils sit on the bird tree of life. These efforts aim to resolve several evolutionary mysteries related to how and when modern bird diversity arose. Our work has suggested that the modern bird group is younger than long-assumed, with many major groups arising rapidly in the early Cenozoic.

Evolution across mass extinctions

The end-Cretaceous (K–Pg) mass extinction dramatically affected vertebrate life worldwide. We are interested in deciphering how this event affected birds and other vertebrates through fieldwork and lab-based studies.

Similar questions in other vertebrate clades

We study the evolution of anatomy and diversification patterns in other (non-bird) groups as well, such as sharks, whales, snakes, mosasaurs, turtles, and non-avian dinosaurs.
