Research interests

My research focuses on the storage and transformation of the plant-litter-derived organic matter in soils and their controls. It is mainly based on the description of the organic matter and the reactive nitrogen species (NH4+, NO2-, NO3-, N2O) dynamics within the different terrestrial compartments by applying a set of approaches (e.g., stable isotopes of C, N, O; UV-Visible spectrophotometry). My work contributes to define formalisms characterizing the coupling processes of nitrogen and carbon cycles involved in the decomposition and the mineralization of organic matter in soils. It contributes to improve the evaluation of plant litter management systems (e.g., in terms of soil fertility, greenhouse gas emission, nutrient leaching) aiming to optimize them.
