Main Research Interests
My main research interest is Genome Evolution, in particular the evolution of fast evolving genes, such as genes involved in reproduction and in host-parasite interaction.
Currently I work on two types of fast evolving traits and genes: 1) Reproductive interactions between Tetranychus urticae and T. evansi and their possible effect on the coexistence between these species; 2) Origin, variability and dynamics of toxin-antitoxin loci, bacterial genes that are involved in the interactions between bacteria and plasmids, using genomic analysis.
