My research activities in recent years have focused on validating various extraction methods: for natural substances from plant matrices and for micropollutants from animal matrices.
– In this way, I have succeeded in developing an analytical methodology that can be applied to a wide range of plant supports (plant parts, essential oils, root exudates) to extract, identify, characterize and assess the antioxidant activity of free radical scavengers. In the field of extraction, we have succeeded in speeding up and significantly improving extraction yields by adding non-ionic surfactants. With regard to root exudates, we have succeeded in qualitatively lowering the limits of detection (LOD) and the limits of quantification (LOQ) in order to identify and monitor the emission of polyphenols involved in soil remediation.
– The expertise I have acquired in this field has enabled me to join the MRCA team (Micropolluants et Résidus dans la Chaîne Alimentaire) of the URAFPA-INRA (Unité de Recherche Animale et Fonctionnalités des Produits Animaux (UFC INRA 340 / EA 3998)) of the University of Lorraine for the contractualization (2013-2017), to take charge of the analytical platform and management of the team developing a methodology for analyzing and extracting micropollutants (PCB-NDL) from animal matrices at the Metz site.
