Education:

PhD in Isotopic Geochemistry (University of Aix-Marseille III, 1997).

Research activity: Head of the inorganic particulate chemistry laboratory.

Laboratory development and field application in atmospheric analytical chemistry (indoor and outdoor) to better constrain the pollutant sources and their environmental and human health impact. Trace and major elements are characterized in sized resolved particle samples and various source-receptor models are employed to decipher between emission sources and their relative contributions to the sampling site. Synthetic biological solutions mimicking the pulmonary surfactants or the gastro-intestinal fluids are tested to estimate the bioaccessible fraction of potentially toxic metal known to induce inflammatory responses or DNA damages. Similarly, various acellular oxidative potential methods (DTT, AA, DCFH) are developed on airborne particles to estimate their intrinsic capacity to induce an oxidative stress on a cellular level.

Involved in various institutional organisms concerning research, regulation and standardization such as the LCSQA, AFNOR, ANSES and CEN.
