2. Research themes

• Characterization and reactivity of natural waters, wastewater and organic micropollutants with oxidants used in water treatment. Reactivity of micropollutants with various oxidants/disinfectants (e.g., ozone, performic acid), kinetic studies, and mechanisms of disinfection by-product formation.
• Organic pollutants in surface waters and wastewaters. Degradation mechanisms of organic pollutants and identification of their transformation products (GC-MS and LC-MS analyses, high resolution mass spectrometry).
• Analytical chemistry and data processing. Development of extraction and analytical methods for organic micropollutants in complex matrices (wastewater, sewage sludge, urine...). Development of software tools for processing high-resolution mass spectrometry data.

3. Current research

• Tertiary treatment of organic micropollutants in wastewater effluents
  - Carboplus project (SIAAP - SAUR): performances of an industrial activated carbon pilot in fluidized bed for the removal of organic micropollutants
  - Potential use of ozone coupled to activated carbon
  - Identification of degradation products (high resolution mass spectrometry)
  - action R2.5 of the OPUR program about wastewater treatment by oxidation(ozonation, UV photolysis, peracids). PhD thesis supervision (Christelle Nabintu Kajoka).
• Analytical chemistry
  - Screenatm’eau project: Method developpement of non-target screening for the analysis of micropollutants by liquid chromatography coupled to high resolution mass spectrometry at the interface water/atmosphere
  - ANR WaterOmics project: Characterization of urban organic by high resolution mass spectrometry. Supervision of PhD thesis (Nina Huynh)
  - action R2.6 and O2 theme of the OPUR program : Lon-term characterization of wastewater by non-targert analyses (high resolution mass spectrometry)
  - MeSeine Innovation program (action 2.2.2): Characterization of surface water contamination by combining non-targeted mass spectrometry analyses with ecotoxicological analyses. Supervision of PhD thesis(Julien Sade)
• Pollutants behavior in urban systems
  - ReFUJ project: PICRI Transformation of a urban brownfield to a park. Study of organic pollutants transfer from the soil to underground water. Simulations in column experiments and influence of hydrological conditions.
  - Roulépur project: Adsorption isotherms of organic micropollutants (alkylphenols and bisphenol A) on soil from a sustainable urban drainage system
