I am teaching Plant Biology, Population Genetics, Conservation Biology, and Molecular Evolution at undergraduate levels. I am also teaching Population Genomics at the graduate level.


Research Interests

I am an evolutionary biologist and my overall field of research is plant population genetics and genomics and their applications to conservation biology. I have been mostly involved in the study of evolutionary implications of mating systems in plants and of the effect of gene dispersal in plants on spatial genetic structure. My research projects involved both theoretical modelling, mostly using numerical simulations, and empirical investigations using genetic markers and more recently, nucleotide sequences.


Recently I focused my research projects on the population genetics and molecular evolution of the self-incompatibility system in Arabidopsis halleri, a close relative to A. thaliana. Me and my collaborators have been investigating the signature of selection on the self-incompatibility locus at different levels: within a population between successive generations, among populations, at the nucleotide sequence level looking at nucleotide diversity, non-synonymous vs synonymous substitution rates, and trans-species polymorphism at the incompatibility locus, as well as hitchhiking effects on nearby genes. I am also involved in population genomics studies aiming at detecting introgression between A. halleri and A. lyrata and identifying selective sweeps associated to the evolution of heavy-metal tolerance in A. halleri.
