Microbial ecology, mycorrhizal symbioses, life history strategies, plant-soil feedbacks, community assembly, ecological networks, behavioral ecology.


In my lab, we study plant-microbial interactions, and their implications in the functioning of terrestrial ecosystems. We adopt a wide variety of approaches (observational and experimental) and concepts (e.g., network theory, behavioral ecology) to test both fundamental and applied hypotheses in plant and microbial ecology. Part of my research aims more specifically at better understanding how microbial traits can help us to more predictably improve current phytotechnologies (e.g., phytoremediation of polluted soils, green roofs, river banks restoration).
