Understanding why some lineages display higher taxonomic diversity and eco-morphological disparity is one of the most outstanding question in evolutionary biology and ecology. My research entailed the use of both molecular and morphological databases to produce exhaustive phylogenies, together with molecular dating methodologies to provide a temporal framework. My key work was the incorporation of fieldwork base study, biometric, morphometric and biogeographical data into macroevolutionary analysis. This allows to address questions about diversification rate variations and their link with key innovations or historical events.
I am currently developing research projects on skull evolution of rodents and shrews, with a focus on turbinal bones and cranio-mandibular muscle system. Understanding how species adapted to their environment has been one of the most intensively studied fields in evolutionary biology. The most spectacular shifts in morphology and ecology seem to be the result of historical events, such as mass extinctions or island formation. Such events provide new ecological opportunities to survivors or dispersers and create the conditions for adaptive radiations Within highly diversified lineages, evolutionary convergence often is (1) a prominent feature of adaptive radiation, (2) generates high morphological diversity within replicated environment, and (3) provides compelling evidence supporting natural selection as a primary mechanism of diversification. Recent advances in X-ray microtomography (X-ray µCT), functional anatomy, and genomics give us the opportunity to study the different aspects of how organisms adapt and converge to their environment. My current research projects propose “pheno-genomic” approaches to studying olfactory and cranio-mandibular adaptations and convergences in small insectivorous placental mammals.
