I am a biologist interested in the general question of how developmental processes can lead to evolutionary change. In particular, my research involves development and evolution of the brain using mammals as model systems. My doctoral thesis studied brain regions involved in olfactory and pheromonal communication in mammals. I discovered several events of parallel co-variation of sensory pathways in distantly related species sharing similar ecological niches. Currently, I study the main axonal tract in the human brain, the corpus callosum, by following two main lines of research: one aims to determine how early neuronal activity affects development of callosal axons, and the other one aims to understand what developmental processes led to the evolution of the corpus callosum in early Eutherian mammals.
