What drives plant evolution? What are the factors that facilitate the rapid diversification of species? These are the main questions that intrigue me. In order to answer these questions, I combine different approaches such as taxonomy, biogeography, phylogenetics, population genetics, and genomics. My taxonomical research has been mostly focused on the Andean genus Calceolaria (Calceolariaceae), on its distribution and species limits. For several years I have been studying how the geological history of an island, inter-island colonization and hybridization affect the diversification process of insular taxa. I have been studying this in genus Micromeria (Lamiaceae) in the Canary Islands using morphometric analyses, single nuclear markers, microsatellites, and more recently, RADseq. I have also studied how whole genome duplication can facilitate adaptation to different environments using the allohexaploid Geum triflorum (Rosaceae) as an example.
