Co-animator of axis 2 "Fertility / multicontamination interactions in Suitma and functioning of Plants and Organisms (ISPO)" since January 2018. The work I am doing concerns the phytoremediation of contaminated soils and more particularly the phytoextraction of metals by hyperaccumulating plants. The model plant studied, Noccaea caerulescens, appears to be one of the most promising candidates for a large-scale application of phytoextraction. In this perspective, my research revolves around three main axes:
- Typology, genetic diversity and aptitude for phytoextraction of N. caerulescens populations,
- Selection of cultivars for phytoextraction of soil contaminated with trace elements,
- Development in the field of phytoextraction of Cd
The research carried out made it possible to identify ecotypes distinguished by characters of major interest for the development of an applied phytoextraction (eg trace element contents in the aerial parts, bioconcentration factor) and to constitute a seed bank in view of plant breeding. The surveys carried out also made it possible to generate a collection of endophytic fungal strains for different ecotypes.
Besides the development of cultivars, the implementation and optimization of phytoextraction requires a better understanding of the factors limiting the installation and development of the plant such as the presence of toxic elements (eg soil salinity, organic pollution) or a fertility defect (eg physical constraints, lack of nutrients). The work carried out explores several ways such as the use of amendments, inoculation by microorganisms or even the supply of phytohormones.

The majority of my lectures are carried out with engineering students from ENSAIA in the agronomy sector. The areas in which I teach are in the soil sciences, agricultural sciences and environmental sciences. I am also responsible for the 3rd year pre-specialization in Environmental Sciences and Engineering. The lectures given are concentrated on two major themes.
FUNCTIONING OF SOILS AND THE CYCLE OF WATER AND NUTRIENTS. The objective is to show how knowledge of the genesis and functioning of the soil makes it possible to set up a reasoned management of mineral and organic fertilization as well as the use of water in agriculture. The lessons are based on fundamental knowledge in association with tools for diagnosing soil quality and its vulnerability.
QUALITY OF THE ENVIRONMENT. The objective is to study the effect of agricultural practices on different types of natural resources. The lessons given to students range from the environmental survey to diagnostic and management tools. Students are brought to apply the knowledge and tools developed in class on real situations in order to prepare them concretely for their future functions.
