Large-scale patterns of biodiversity : the relative role of historical/evolutionary and ecological processes.
My research in the fields of macroecology and biogeography is presently focused on explaining large-scale geographical patterns of biodiversity in aquatic ecosystems. One of the main objectives of this field of research is to tease apart the relative role of historical/evolutionary and ecological processes in shaping current biodiversity patterns.

Species distribution modelling : winners and losers in the face of past, present and future global changes
I am also seeking to explain the distribution of aquatic vertebrates using a multi-scale hierarchical approach, and to understand the processes by which distributions change over time (both past and future). More particularly, I intend to assess the extent to which the distribution of aquatic vertebrates (1) changed in the face of past climate changes (e.g. during the Quaternary period) and (2) will change in the face of current global changes (e.g. climate warming). Overall, this ongoing work is at the intersection of multiple disciplines such as biogeography, statistical ecology, paleoecology and conservation biogeography.

Causes and consequences of species invasion: a multi-scale approach
My works in the field of invasion biology aim at identifying the relative roles of anthropogenic activities and ecological processes in explaining the causes and consequences of species invasion in aquatic ecosystems. To this aim, i explore the different stages of the invasion process (introduction, establishment, spread and impact) from local to global scales. I am also interested in using "exotic species introductions" as large-scale experiments to test competing ecological and biogeographical theories.
Overall, the results of these works have (i) applied implications as they can help wildlife managers to make scientifically-based policy decisions regarding species invasions and the conservation of native species; (ii) fundamental implications as exotic species can provide new insights to our understanding of ecology, evolution and biogeography.
