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"
