My research activities concern the study at different scales of the dynamics of organic matter and organo-mineral microstructures within soils, as a revelation of their bio-functioning and evolution. The approach is based on the morphological and analytical characterization of organo-mineral associations and the monitoring of their evolution in situ, with a particular focus on microstructures (0-20 µm). Organo-mineral microstructures can indeed be considered as bio-physicochemical indicators allowing to specify the relationships between the dynamics of the structure and soil functioning, particularly under the impact of biological factors.

This monitoring of aggregation within soils is carried out from soil profile to macro- and micro-aggregates, using methods specific to the conservation of initial structures. These methods include granulo-densimetric fractionation, thin soil section realization or transmission electron microscopy, methodologies developed by the staff of the SCMF, Service Commun des Matériaux Friables, within the LSE.

I use this approach to study the dynamics of soil aggregation, from the genesis of aggregates to changes in soil structure due to various impacts such as those of biological activity, cultivation practices or soil rehabilitation. Within the framework of the Technosols study, the microstructures approach is put into the perspective of a functional pedology, with the dual objective of specifying the agro-environmental quality of the environments and contributing to a representation of the functioning of Technosols, particularly under the impact of the activity of living organisms: plants, fauna and microflora.
