Eco-evo-devo - Bats - Teeth - Adaptation - Noveties - Deep homology


I am an evolutionary developmental biologist. My research aims to answer broad evolutionary questions related to the evolution of animal forms to understand how species adapt to various environments, on Earth and beyond. I mainly use the diversity of bats to study the evolution of dentition, dietary and sensory systems but also mammals in general. Please find here more about my research and scicom projects!

I will hire soon one postdoc, one PhD student and one technician through my ERC grant!
