My research focuses on the assessment of potential impacts of global changes on aquatic biodiversity and ecosystem functioning. I am particularly interested in the consequences of climate change and anthropogenic activities (e.g. hydro-electricity) on stream fish and semi-aquatic mammals, and the development of methods to design efficient conservation measures for these organisms.
