I have done a PhD in Biology on competitive interactions between native and exotic fish species. I'm now investigating ecological and evolutionary dynamics in freshwater habitats by focusing on the causes and consequences of intraspecific diversity and on host-parasite interactions. I generally combined various tools including experimental ecology, molecular ecology, meta-analyses, empirical surveys and causal modeling. I'm broadly interested on the processes underlying biodiversity, and how biodiversity is interacting with its environment. Many of my works are related to applied and societal issues such as habitat fragmentation and the management of exploited populations.
