Current research interest

• Biological invasion processes: molecular ecology and evolutionary biology to investigate introduction patterns, spread and evolution of marine invasive species
• Evolutionary biology applied to marine coastal species: historical perspective of changes of marine species ranges, hybridization processes etc.
• Population genomics and population genetics for the study of connectivity between populations of coastal marine species
• Mating system and reproductive strategies in algae and invertebrates.
