From February 5, 2019, to the present, I have been working as a Scientist at Sciensano in Brussels, Belgium. In this role, I am responsible for the Food Contact Materials National Reference Laboratory and serve as the Belgian representative at the European Reference Laboratory for food contact materials. I manage the practical organization of daily laboratory activities in accordance with ISO 17025 and oversee routine analysis of food additives and food contact materials. My work includes the development and validation of analytical methods for detecting and quantifying various substances in food matrices and food contact materials using advanced techniques such as GC-MS/MS, LC-MS/MS, LC-UV, LC-FLUO, GC-FID, and LC-HRMS. Additionally, I participate in proficiency tests, write scientific reports, papers, and procedures, supervise junior scientists, analysts, and interns, and organize workshops for Belgian official control laboratories. As the lead scientist, I also spearhead research projects related to food contact materials and food. Between January 2, 2019, and April 15, 2019, I worked as an Assistant Project Manager at Eurofins Amatsi Analytics in Toulouse, France.

Prior to that, from February 19, 2018, to January 2, 2019, I served as a Bioanalyst at Amatsigroup in Toulouse, France. My duties involved performing routine analyses on biological matrices for clinical trials, developing and validating analytical methods on biological matrices, identifying and resolving technical issues, and calibrating HPLC-MS/MS instruments.
