  • Perfil profesional

    My research is focused on the systematics and evolution of species-rich plant lineages. I use molecular phylogenetics to address questions about evolutionary history, morphological evolution, and to unravel patterns of species diversification and geographic distribution of the mega-diverse and widely distributed genera Croton and Euphorbia (Euphorbiaceae). I am interested in understanding the intrinsic and extrinsic factors involved in the process of species diversification and whether key adaptations or/and ecological opportunities have triggered explosive diversification events in the evolutionary history of those lineages. Other questions that I am starting to address are related to the evolution of floral morphology in Croton and its possible relation to changes in pollination systems. Finally, part of my work also involves the construction of taxonomic classifications of lineages within Euphorbiaceae using a phylogenetic framework but considering morphological patterns.  In doing so, I also conduct taxonomic revisions of selected groups, contribute to regional floras and checklists, and describe new taxa.
