“My research focuses on the study of herbaceous plants (individual or plant community) to understand the functioning and dynamic of agroecosystems and their agronomical and ecological properties. One of the main objective of this work is to drive the diversification and conception of cropping systems less dependent on external inputs, less sensitive to climatic hazards, and more favorable to soil fertility (agroecological conceptual framework).”
