Research Interests

*Transport of pesticides through soils: coupling between physical, physico-chemical and biological processes affecting pesticide dissipation in soils

* Non-equilibrium transport models (double-porosity, multiple permeability, kinetic sorption)

* Hydrodynamic dispersion of reactive solutes in porous media

* Explicit description of soil pore space and soil bio-physico-chemical heterogeneities at the pore scale

* Cellular automata (Lattice Gas, Lattice Boltzmann)

* Tomographic images and thin-sections of soils

Current Projects and recently completed projects

Spatial modeling of pesticides dynamics in soil porosity - 2007-2008 - Innovative scientific project INRA

Spatial heterogeneities induced by incorporation of organic waste products at the scale of crop profile: description and modeling of their impacts on the dynamic of mineral and organic micropollutants - 2004-2007 - French National Project ACI "ECCO"

Thèse sur la modélisation de l’évaporation dans les milieux poreux aux échelles microscopiques

Fonction principale et transversale, responsabilités :

Chercheuse, co-animation du TS Climat, participation au groupe de travail INRAE Modélisation des Agroécosystèmes, référente du laboratoire de Physique du Sol

Ce que je fais : 

Rôle des non-équilibre d’origine physique et/ou chimique dans les transferts d’eau et de substrats carbonés dans les sols (échelle profil de sol) ; rôle de l’architecture des sols dans le devenir des matières organiques et des contaminants organiques ; mise en œuvre d’un changement d’échelle pour intégrer les informations obtenues sur les interactions se produisant aux échelles des habitats microbiens (lieux de la biodégradation) vers des modèles macroscopiques à échelle continentale.

Techniques, instruments, méthodes et dispositifs utilisés :

infiltration sur colonnes de sol non perturbé, modèles 1D et 3D, tomographie rayons X, analyse d’images, plateforme de modélisation Vsoil
