The Clarke Lab seeks new data to inform how avian diversity and distributions have changed across their deep histories.

Current Postdoctoral Researchers

Lucas Legendre
Research Associate (since September 2023)
Postdoctoral Researcher (September 2018–August 2023)
Ph.D., Sorbonne University

Lucas’ initial training was in bone histology, with a focus on paleophysiology and phylogenetic comparative methods. In the Clarke Lab, he uses those approaches to study the morphology of the avian syrinx, as well as the evolution of reptile eggshell microstructure. Lucas is also involved in teaching and mentorship for the Curiosity to Question course, the Geoscience Ambassadors Program, and various students projects in the lab.
