Presentation
I carry out my research activities in the team Chemistry and Electrochemistry of Materials of the Jean Lamour Institute (IJL – UMR CNRS 7198, University of Lorraine (UL), France). I have a strong expertise in the field of electrochemistry (20 years) and an extensive knowledge in ionometallurgy (ionic liquids and deep eutectic solvents) (15 years). My teaching activities deal mainly with electrochemistry, corrosion, solution chemistry and recycling of metals, for Bachelor and Master level students.
I defended my PhD in analytical electrochemistry in 2002 and worked then as a post-doctoral fellow in Paris VI (corrosion) and Lyon I Universities (analytical electrochemistry). In 2005, I worked as temporary assistant professor in the green chemistry research group of the Environment and Molecular Chemistry Laboratory (Polytech Savoie) where I studied the physicochemical characterization (chemical and electrochemical properties) of new developed ionic liquids. I joined the Jean Lamour Institute in September 2006 where I initiated a thematic concerning the electrodeposition of new high performances thermoelectric materials in ionic liquids (rare-earth doping and nanostructuration by solvent templating effect). Since 2009, I develop ionometallurgical treatments (liquid-liquid extraction/electrodepostion coupling, electrochemical leaching/eletrodeposition coupling) in ionic liquids and deep eutectic solvents by electrochemical techniques, with a focus on WEEE (Ta, Au, Pd, Pt, Ag). Whatever the targeted application, my experimental approach of electrochemical processes is centered on a thorough study of electrochemical reactions mechanisms, thermodynamics and kinetics.
I supervised several PhDs in electrochemistry: 4 PhDs in the field of ionometallurgy for recycling, and 3 PhDs in thermoelectric nanomaterials synthesis using ionic liquids. In the field of ionometallurgy for recycling, I was involved in the national ANR project SILEXE, in a national CEATech project, an I am currently the coordinator of the national ANR project EE4Precious.
