Thématique(s) de rechercheMy research belongs to the field of aquatic ecology and spans a wide array of thematics ranging from species behavior to ecosystem dynamics. I’m especially interested to evaluate how lake biodiversity can respond to both global and local anthropogenic forcings with a special focus on biological invasion and climate change. I use food web reconstruction and modeling to quantitatively evaluate alternative scenarios of ecosystem and biodiversity changes that can support lake stakeholders to elaborate adaptive management.
