IMG_6022Dr Marie-France Dignac is an isotopic organic geochemist at UMR Ecosys, INRA, France. Her research activity is focused on field and laboratory experiments using biomarker (cutins and suberins, lignins, phospholipid fatty acids) and isotopic (13C) tools to explore the fate of plant biomass in soils and the role of soil microbial biomass in C cycling. She is involved in the coordination of the French national network on organic matter (ResMO) since 2004. @MFDignac



Sans titreDr Cornelia Rumpel is a biogeochemist at the Institute of Ecology and Environmental Sciences, CNRS, France. Her research deals with stabilisation processes of soil organic matter at different temporal and spatial scales in tropical and temperate environments. She is involved in the international 4 per mil initiative as a member of the Scientific and Technical committee. @CorneliaRumpel




Dr Abad Chabbi is a plant ecologist and soil biogeochemist. He worked at the Louisiana State University, USA; the Faculty of Environmental Science in Cottbus, Germany; the University of Pierre & Marie, Curie (UPMC), France; and the INRA research council where he has been leading the National Observatory for Environmental Research-Agro-Ecosystems, Biogechemical Cycles and Biodiversity ( since 2009. Abad Chabbi is currently Director of Research at the French National Institute for Agricultural Research (INRA) and his research centers on the linkage between soil carbon sequestration, nutrient availability and stoichiometry in the plant-soil system and their relations to land use management and climate change. He is also working with strategic Research Infrastructures and interested in science policy and societal challenges. Throughout his career, Abad Chabbi has focused on coordinating international and multidisciplinary projects, including ExpeER and AnaEE under the strategic European Commission framework. He also chairs a Working Group at the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, at the Hercules Foundation for Investments in Research and Innovation”, Brussels… and provides expertise to the German Research Science Foundation, the European Commission’s Direction of Research and Innovation as well as the Chinese Academy of Science, the Canada Foundation for Innovation and the American National Science Foundation. @AbadChabbi
