Broadly, I am interested in the evolutionary history of mammals with a special interest for Artiodactyls. My work focuses on the phylogenetic relationships of suids and hippos. Hippos being the closest relatives of whales according to molecular data, this topic is directly related to the terrestrial origin of cetacean, which is one of the problematic issues of mammalian evolution.
I am focusing on endocranial features of extinct and extant artiodactyls such as the middle and inner ear, and brain morphology. This promising field of research, “paleoneurology”, will allow us to understand the evolutionary history that led to the complexity of artiodactyls brain that we know today.
