Work-Study Program – L3 Chemistry (Métiers de la Chimie)
September 1, 2025 – August 28, 2026
Laboratory Technician: Performing laboratory analyses, preparing practical sessions, maintaining equipment, and carrying out measurements and field sampling.
ENGEES (École Nationale du Génie de l’Eau et de l’Environnement de Strasbourg) is an engineering school specialized in water, environmental, and sustainability fields. My work-study program takes place within the LEE laboratory (Laboratory of Water Studies), an ISO 9001-certified laboratory, ensuring rigorous, standardized, and quality-oriented working methods.
The laboratory is structured into two complementary sectors: an education unit, dedicated to teaching and student practical sessions, and a quality control unit, responsible for water analysis and monitoring. This organization allows me to evolve in an environment that is both academic and professional, closely aligned with the requirements of the environmental sector.
My Project at ENGEES
At ENGEES, I was fully involved in the activities of the LEE laboratory, across analytical, educational, and organizational aspects. I contributed to environmental chemical analyses on various matrices such as water, soil, and plant samples, while also supporting waste management, routine laboratory operations, and equipment maintenance.
A significant part of my work focused on the metrological monitoring of balances and pipettes, ensuring measurement reliability in compliance with quality standards. I also provided technical and educational support to the school’s training programs, particularly during practical sessions in chemistry and process engineering, as well as in research projects and continuing education programs.
My work-study experience allowed me to actively contribute to the implementation and drafting of standardized analytical protocols, particularly for TOC analysis using a TOC analyzer (in accordance with EN ISO 20236) and for ICP-AES analysis (according to NF EN ISO 11885).
These responsibilities enabled me to develop a rigorous approach to analysis, focused on reliability, traceability of results, and compliance with standards, while fully integrating into the operations of an ISO 9001-certified laboratory.
