I am a freshwater ecologist interested in ecosystem functioning, and especially in the aquatic fauna of rivers and lakes. As part of my PhD, I am studying the impact of biological invasions (fish species introduction) on the macroinvertebrate community of high mountain aquatic ecosystems. I use a combination of both genetic techniques and morphological approaches to characterize the biodiversity of the invertebrate communities, in addition to assess the threats that they face in the context of Global Change.
