Welcome to the CEFE

The CEFE is currently the largest French research center in Ecology and Evolutionary Ecology. Our Mission: perform independent, fundamental scientific research on the dynamics of biodiversity, planetary environmental change, and sustainable development. The links between society and ecology is a theme of increasing importance in oour research.

If you are interested in who does what on a specific theme or topic at CEFE, please go to the WHO DOES WHAT tab and use the proposed tags. You will have direct access to the pages of the persons listed for a given tag.

If you are interested in what the different research Departments at cefe do and the focus of their respective teams, please go to the RESEARCH tab and navigate the Departments and their teams.

Research questions

How ecological processes and human activities affect biodiversity and ecosystem functioning?

To address this question, I assemble approaches from community ecology, functional ecology and quantitative ecology. I mainly focus on cultivated ecosystems and their associated plant communities, including both cultivated and wild species (i.e. arable weeds). 

My researches hinge on three particular thematics:

1) Plant invasion: Which ecological processes drive plant invasion success? How invaded species affect local plant communities?

2) Weed community ecology: How stochastic and deterministic ecological processes shape weed community assembly in arable fields? Are weeds ecological outliers?

3) Biodiversity-ecosystem functioning: How the different facet of plant diversity (eg: species richness, functional diversity, species relative density) affect ecosystem functioning? How the diversity of cultivated species can be manipulated to increase yield stability?
