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, Research Officer, CNRS, Geology Laboratory, 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.
Ludwig Jardillier, Senior Lecturer, University of Paris Sud, 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.
Florence Hulot, Maître de conférences, Université Paris Sud, 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.
Emma Rochelle-Newall, Research Director, IRD, iEES Paris
The central theme of Emma Rochelle-Newall’s research is the study of interactions between heterotrophic and colored bacteria and dissolved uncolored organic matter. She also examines how anthropogenic impacts, such as the increase in inorganic and organic waste, modify carbon transfer between autotrophic and heterotrophic compartments in order to understand the impacts of human activities on aquatic systems.
