What I'm looking for

I’m looking for a role where I can develop and validate analytical methods for water quality, work on organic matter and contaminants in complex matrices, and contribute to practical, rigorous environmental research with a strong scientific team.

I’m a PhD in Environmental Chemistry, specialising in the characterisation of organic matter and aquatic contaminants. My work focuses on turning complex water-matrix challenges into reliable, validated analytical insight.

During my Environmental chemistry PhD Experimental Work (LASIRE, University of Lille), I investigated organic pollutant analysis, disinfection by-products, and trace inorganic pollutants. I developed innovative approaches for characterising organic matter transformation products in drinking water treatment, including advanced chromatography workflows.

I’m experienced in method development and scientific dissemination, with hands-on expertise in chromatography and spectrometry. I use HPLC (UV, FLD, ICP-MS) and HPSEC to study complex matrices, and I apply ion chromatography, ICP-MS, and CI-ICP-MS for targeted halogen and trace-metal quantification.

I also support the education side of science through practical teaching (Master 1 in Water Sciences). I’m comfortable optimizing experimental protocols (oxidation, derivatisation), interpreting scientific data, and communicating results clearly—because rigorous analysis directly improves water quality decisions.
