    Investigation on evolutionary/systematic aspects is my main goal. My doctoral research focused on the macro- and microevolutionary processes that have occurred in one of the most representative Mediterranean plant groups (Cistus L.). During my PhD training I worked analysing both DNA sequence data and morphological characters to address an array of evolutionary/systematic questions at different temporal and geographical scales. As a postdoctoral fellow, my research is part of the project “Evolution of the personate flower: macro- and microevolutionary analyses of the tribe Antirrhineae” and aims to identify whether diversification of the Antirrhineae lineages implicated in the colonisations between the Old World and the New may have been promoted by the appearance of new habitats and pollinators. We expect that new ecological conditions in the New World triggered new mechanisms (particularly hummingbird pollination) subject to be inferred using phylogenetic and genetic approaches.
