My interests lie in understanding the drivers of variability in phenotypic traits and their implications for eco-evolutionary dynamics. I particularly focus on traits involved in communication, cooperation, dispersal and host-microbes interactions. Depending on the question, I use various model species from vertebrates to microorganisms, in order to perform empirical and theoretical research both in natural and experimental systems.
Currently, my two main projects focus on 1) the eco-evo of variability in dispersal strategies, and 2) the dynamics and function of protists in freshwater ecosystems (see below).
Eco-evo of variability in dispersal strategies
I am interested in understanding the drivers of dispersal movements and their consequences at the metapopulation and metacommunity levels. Individuals are increasingly recognized to adjust their dispersal decisions to their phenotype and the environmental conditions. Such non-random movements in the landscape might deeply alter meta-population, community and ecosystem functioning. Our understanding of the mechanisms and evolution of movement strategies is therefore crucial for our ability to understand and predict species and community evolution, especially under the current global environmental changes.

Eco-evo dynamics and function of protists in high mountain lakes
Ciliates play major roles in the ecological dynamics of aquatic communities, including the (de-)regulation of trophic state. Their sensitivity to environmental changes and the subsequent consequences for aquatic ecosystems is however poorly understood. In a project coupling quantification of microbial communities dynamics through eDNA in mountain lakes, and experimental approaches in microcosms, we study the sensitivity of ciliate communities to environmental changes, the underlying mechanisms, and the role of these changes for ecosystem functioning.
