• July 1990: Habilitation – University of Poitiers – France
• July 1987: PhD in Water Chemistry – University de Poitiers – France
• June 1983: MSc in Environtal Eng.-University of Chambéry – France
• June 1981: BSC Science Chemistry & Biology – Univ of Angers – France

• Water analyses, isolation and characterization of natural and effluent organic matter (NOM and EfOM)
• Physical chemical treatments (coagulation, adsorption, ion exchange) for the removal of dissolved organic matter
• Membrane filtration: Characterization of surface interactions and nature of organic foulants of low (polymeric and ceramic) and high-pressure membranes (river water, desalination, wastewater reclamation)
• Oxidation/disinfection (chlorination and ozonation) and Advanced Oxidation Processes (Solar based, UV-based, catalyst based AOPs): reaction mechanisms, performances and by-products formation

My research activities pertain to the isolation, characterisation and reactivity of Dissolved Organic Matter (DOM) i.e., Dissolved Organic Carbon (DOC) and Dissolved Organic Nitrogen (DON), in the aquatic environment and through water treatment trains (i.e., drinking water and water reclaim treatment plants). The major research topics are: the formation (analysis, reaction mechanisms) of Disinfection By-Products during chlorination, chloramination and ozonation; interactions of DOM with surfaces in removal processes (coagulation, sorption); DOM inducing UF and RO membranes fouling in drinking water (fresh and seawater feed) and reclaimed water treatment trains. Another major aspect of my research refers to the degradation of contaminants in the aquatic environment (photolysis, photoinduced degradation) and during catalytic processes and Advanced Oxidation Processes.
