RESEARCH EXPERIENCE

Ph.D. 3-years French Ministry of Research Fellowship

• Development of a new technique for in-situ sampling of nanoparticles.
• In-situ monitoring of soil and atmospheric colloids reactivity (organic & inorganic) applying HRTEM-EDX, SEM-EDX and Laser Granulometry.
• More than 500 hours of TEM experience.
• Determination of the factors influencing colloids and nanoparticles in the environment.
• TEM, Cryo-SEM and ESEM investigation on bacteria-As interaction.

        Main results:

• Hydrodynamic properties are controlling the distribution of nanoparticles with depth and time in soil
• Rain conditions and vegetal cover are controlling the distribution kinetics in atmospheric fallout
• Bacteria are an important vector of heavy metals
• Aggregation processes are leading the reactivity of nanoparticles

M.S. 

• Development of a new geochemical concept for tracing the provenance of ceramics using the behavior of chemical element during weathering by applying Microprobe and Laser Ablation ICP-MS.

        Main results:

• Interdisciplinary study (geosciences & archaeology) improves the provenance of ceramics
• Technology of ancient time can be determined by mineralogical study
• According to the source of parent material, ceramics have a clear isotopic signature.
