The developmental basis of morphological evolution

I am an evolutionary developmental biologist at UCLA. My research is broadly related to mammalian eco-evo-devo and aims to answer broad evolutionary questions related to the evolution of animal forms in various environments. I mainly use the incredible diversity of bats to study the evolution of dentition, dietary and sensory systems. Please find here more about my research and outreach projects!
