Research interests

My research focuses on the plant litter storage and transformation in soils and their controls. It is mainly based on the description of organic matter (DOM, VOC) and reactive nitrogen (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. Finally, 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.
