Research and skills

My research interests focus on the fine-scale biochemical mechanisms that give rise to patterns in large-scale ecosystem processes.

I am particularly interested in the role of biodiversity, habitat and climate change on microbial communities (fungi / bacteria), and in turn, on the multifunctionality of terrestrial ecosystems and the coupling between cycles of carbon (C), nitrogen (N) and phosphorus (P). The main challenge of my research is to identify the mechanisms by which biodiversity loss and climate fluctuations affect the stability of soil functions, and thus the provision of ecosystem goods and services essential for human well-being. My research intersects the fields of functional ecology, chemistry, community ecology and microbial ecology.

Ongoing projects

• Project VR (Swedish Research Council) - Context-dependency of biodiversity effects.

In partnership with the Swedish University of Agriculture in Uppsala and Umeå and CSIRO in Glen Osmond, Australia, I address the question of how the environmental context influences the effects of biodiversity loss on ecosystem processes. To do this, we use a gradient of 30 islands (each being an independent ecosystem), collectively representing a chronosequence of boreal islands over 5000 years. Different species (blueberry, lingonberry ...) and functional groups of plants (moss, tree, shrub ...) have been removed for more than 20 years to simulate a loss of biodiversity in each of these islands. The goal of this project is to identify the mechanisms by which plant diversity influences soil functioning and biogeochemical cycling across contrasting ecosystems.

• Project Dipticc (Agence Nationale de la Recherche) - Diversity and Productivity of Trees in the context of Climate Change

In partnership with Bordeaux Sciences Agro, BIOGECO (Bordeaux), EEF (Nancy) and CEFE (Montpellier), the objective of this project is to assess if tree diversity can mitigate the negative effect of climate changes on productivity and soil functioning. To do this, we use two experimental sites: ORPHEE in which more than 25000 trees of 5 local species were planted under all possible conditions; BIOPROFOR which consists of six natural sites in the Alps in which tree species are studied at different levels of elevation. The main objective of the project is to test if multispecific stands are more stable (resistant / resilient) to drought than monospecific stands. In particular, we study soil functioning through roots, mycorrhizal fungi and their impact on the availability of nutrients and carbon.

•Project TeaTime4Science - Can drinking tea help us understand climate change?

The goal of this large-scale participatory project is to bury green and red tea bags and retrieve them three months later to measure decomposition rates. In partnership with the ONF and the RENECOFOR network, more than 1200 tea bags were burried in more than 100 forest sites in France. The results of this project will help to understand what are the main factors influencing the decomposition process at large spatial scales (climate, tree species, geology…). In addition, these data will enter a global database to better understand the role of climate on the decay of organic matter.
