I received a Ph.D. in Biology (Evolutionary Biology) from the University of Lisbon in 2007 and I have been applying population genetics/genomics, phylogenetic and phylogeographic approaches to understand evolutionary patterns and processes in several insect species. Currently, I am carrying out research on genetic-environmental associations in insect pests and vectors of plant disease in an organic vineyard agroecosystem. I am interested in understanding the factors affecting the distribution and temporal patterns of dispersal of the green leafhopper, that cause damage in the vines. I am also focused on the study of the diversity, dispersal patterns and local adaptations of the insect vectors of the plant pathogenic bacteria Xylella fastidiosa, in particular of the meadow spittlebug, Philaenus spumarius (Hemiptera, Auchenorrhyncha, Aphrophoridae), and its closely related species.
In previous works I have studied genomic signatures of introgression between commercial and native pollinators, Bombus terrestris (https://doi.org/10.1111/eva.12732) and I have applied genome-wide analysis to the study of local adaptation in Drosophila subobscura (https://doi.org/10.1093/molbev/msx247). I have also led a project on the adaptive significance and genetic basis of a balanced colour-polymorphism in the spittlebug Philaenus spumarius, where we studied: the phylogeographic patterns (https://doi.org/10.1371/journal.pone.0098375); the genotype-phenotype associations in the colour morphs (https://doi.org/10.1186/s12863-016-0455-5); and the differential survival and reproductive success of the different colour morphs (https://doi.org/10.1111/een.12252).
