I focus on the effects of global change on natural communities and ecosystem processes. Though I primarily investigated on the effect of biodiversity loss on ecosystem functioning in the past, my current research is rather dedicated to the influence of temperature and nutrient availability on trophic interactions and ecosystem processes.
I am also highly interested in the effects of natural gradients in both temperature and resource availabililty, and how they may help understanding current and future patterns in community structure and ecosystem processes.


I address these questions using the heterotrophic food-webs from headwater streams as model systems. These food-webs strongly rely on the decomposition of allochtonous leaf litter, and include microbial decomposers (e.g. aquatic fungi), detritivorous macroinvertebrates (insect larvae and crustaceans) as well as predators (insect larvae and vertebrates). It is a well characterized, tractable and perfectly appropriate system to investigate on my research topics.
