As part of this postdoctoral position, you will have the opportunity to contribute to innovative research at the heart of current environmental challenges. You will be responsible for the physicochemical analysis of complex samples of environmental interest, such as secondary organic aerosols and non-combustion-derived particles. Particular attention will be given to the study of micro- and nanoplastics, in order to assess the relevance and efficiency of depollution and recycling processes.

You will work in a stimulating scientific environment, making use of state-of-the-art instrumentation. You will use both mass spectrometry technologies developed within the laboratory (notably laser-assisted mass spectrometry) and cutting-edge instruments (ion mobility coupled with time-of-flight mass spectrometry (TimsTOF), Orbitrap).

Your work will be part of major, well-recognized research programs, including the CDP AREA (Aerosol at the heaRt of the Earth Atmosphere system) as well as several ongoing ANR projects (including the ANR EffPhob project). You will therefore actively contribute to high-impact research, interacting with multidisciplinary teams.

The successful candidate will be responsible for the entire experimental and scientific workflow, from sample collection to the dissemination of results. In this context, their activities will include:

Designing and implementing protocols for the collection and preparation of environmental samples;
Conducting experimental analyses using the mass spectrometry techniques available in the laboratory, as well as optimizing analytical methods if necessary;
Performing advanced data processing, including statistical and multivariate approaches, and potentially developing suitable data analysis tools;
Interpreting results from a physicochemical and environmental perspective, in line with the objectives of the ongoing projects;
Writing scientific articles and promoting the research outcomes (publications, presentations at national and international conferences);
Participating in scientific discussions within the team and with project partners.

UMR 8523 PhLAM (Physics of Lasers, Atoms and Molecules, CNRS – University of Lille) brings together around 180 members and conducts research on light–matter interactions, structured around five main themes: Photonics, Quantum Systems, Dynamics of Complex Systems, Molecular Physics at Interfaces, and Theoretical Molecular Physicochemistry.

Within the framework of molecular physics activities, the ANATRAC research group (Trace Analysis, 11 members) has gained international recognition in two-step laser mass spectrometry (L2MS) and its applications in environmental science, Earth sciences, and biology/medicine. The international visibility of this research has led to support from several projects (European, national, and regional), with current involvement in 4 ANR projects, 2 CPER programs, 1 CDP, as well as the PEPR “Origins” program (targeted project µL2-HRMS). As part of the CPER and PEPR projects, the installation of two new instruments (Orbitrap and timsTOF) has recently been completed, complementing an already extensive set of instrumentation.

The successful candidate will work within a team of 6 permanent and 5 non-permanent staff members at the PhLAM laboratory and will collaborate with other teams across the campus.

The position is based in Villeneuve-d'Ascq, at the Cité Scientifique campus.

This position falls within a sector subject to the protection of scientific and technical potential (PPST). In accordance with regulations, your appointment must therefore be authorized by the relevant authority of the Ministry of Higher Education and Research (MESR).
