I work with animals inhabiting deep-sea chemosynthesis-based ecosystems such as hydrothermal vents, cold seeps and organic falls. I am interested in the evolutionary history of these animals, and I use phylogenetic methods to learn more about where they came from, and how they adapted to these unique habitats. I also study genetic connectivity between different geographic areas, and I use molecular tools to support species delimitation and descriptions of new species.
