About Me

EDUCATION/TRAINING.

2001 Habilitation à Diriger de Recherche de l’Université Pierre et Marie Curie.

RESEARCH TOPICS.

The overall focus of my research concerns the study of interactions between major and trace elements and major constituents of water and soil in biogeochemical cycles. Continental surfaces are the locus of significant transfers and exchanges of materials. At the watershed scale, these transfers are made in a large geochemical cycles: weathering of rocks - transport by rivers - sedimentation - diagenesis.

To understand these transfers and the environmental role of organic matter, it is necessary to determine the speciation of chemical elements in the environment: dissolved, colloidal, and / or solid. The adsorption and complexation of major and trace elements by finely divided materials (ie colloidal minerals, organo-inorganic and organic) influence transfer processes in rivers and soils.

A - Experimental study of processes at interfaces, understanding the mechanisms that control the speciation and transfer of elements in water and soil. He is studying the reactions of heterogeneous solid-liquid type.

B - Modelling of interactions between major and trace elements and various components of water-soil system.

C - Speciation of chemical elements in natural environments (water and soil).

D - Study of the early weathering.
