Associate researchers
Associate researchers are external scientific experts associated with the laboratory for scientific coordination missions, technical and technological expertise and communication and supervisory activities. Their status allows them to participate in the design and implementation of scientific and research and development projects hosted by our unit.

Pierre Barré, Researcher, CNRS, Geology Laboratory of Ecole normale supérieure
Biogeochemist and soil specialist, Pierre Barré is a researcher assigned to the Geology Laboratory of the Ecole normale supérieure where he studies the role of soil mineralogy in the functioning of the ecosystem and in particular the different forms of carbon stability in the soil. This work combines mineralogy, biogeochemistry and ecology in order to characterize the effects of climate change.
Amandine Cornille, Junior Investigator, CNRS, Génétique Quantitative et Évolution - Le Moulon
Amandine Cornille is currently group leader of a young ATIP / AVENIR team created in January 2019 at the Genetic Quantitative and Evolution-Le Moulon lab (France). Her team uses combinations of various approaches (laboratory experiments, field work, modeling, population genetics and genomics) for contributing to our understanding of plant, insect, bacteria diversities and of how organisms evolve and adapt to their environment. In particular, her team focuses on the genomics of adaptation of apple-aphid interactions in the context of domestication. They are also leading the construction of an orchard of wild apples at Univ. Paris Saclay for scientific, mediation and conservation purposes.

Isabelle Gounand, Researcher, CNRS, IEES-Paris
Researcher at the interface of community ecology, ecosystems and spatial ecology, Isabelle Gounand is interested in the interactions between different ecosystems, habitats or communities, via spatial flows of resources or movements of organisms. Her research aims to study how these spatial dynamics contribute to the functioning of ecosystems and their response to disturbances.

Aurélie Goutte, Senior Lecturer, EPHE, METIS
Aurélie Goutte’s research aims to better understand the fate and effects of pollutants in aquatic ecosystems. On the one hand, the aim is to study the transfer and transformation processes of contaminants of agricultural or urban origin within food webs, from prey to predators, and from hosts to parasites. On the other hand, the aim is to assess potential effects at different biological scales in natural or experimental conditions.
Florence Hulot, Senior Lecturer, Université Paris Saclay, ESE
Ecologist of communities and ecosystems, Florence Hulot studies freshwater ecosystems, especially shallow lakes. Her research objectives are to understand how disturbances such as an increase in temperature, a change in the mixing regime of the water column and increased inputs of organic matter can modify the composition of planktonic communities and the functioning of aquatic interaction
networks.
Ludwig Jardillier, Senior Lecturer, University of Paris Saclay, ESE
Ludwig Jardillier’s research activities aim to better understand the diversity of microorganisms, the processes that structure this microbial diversity and, in turn, the role of microorganisms in the functioning of marine and freshwater aquatic ecosystems. His research is part of a broader ecological question that aims to understand the links between diversity and stability in ecosystem functioning.
