Laboratory: Centre of Education, Research and Innovation on Energy and Environment (CERI EE)
Supervisors: Dr. Hui CHEN, Dr. Joel BRITO, Prof. Véronique RIFFAULT
Type of contract and duration: Full-time Postdoctoral – 16 months
Workplace: Bourseul Campus, Douai, France
Context:
IMT Nord Europe is a public higher-education and research institution belonging to the Institut Mines-Télécom (IMT) group, under the supervision of the French Ministry of Industry. Its missions include engineering education, scientific research, and innovation in support of sustainable territorial development. For more details, please visit: www.imt-nord-europe.fr/en
This postdoctoral position will be hosted within CERI EE at IMT Nord Europe, in the research axis “Observations, Sources and Processes in the Atmosphere” (OSPA). The host team develops advanced experimental and data-analysis approaches to characterize atmospheric aerosols, their sources, and their impacts on air quality and health.
This research is part of the PEPR VDBI RESILIENCE project (https://pepr-vdbi.fr/projets-laureats/projets-resilience) and the CPER ECRIN project. It aims to develop transdisciplinary approaches to evaluate how urban planning and mobility-transition policies can improve living conditions and generate co-benefits for air quality and health.
The Postdoctoral research focuses on the characterization of emerging air pollutants, with a primary emphasis on ultrafine particles (UFP) and black carbon (BC). Through high time-resolution measurements and advanced source apportionment approaches, the researcher will investigate contrasting urban environments using:
· Enhanced field campaign datasets to be collected in 2026 at twin sites in two French cities (Lille and Marseille) within the framework of the RESILIENCE project
· Concurrent observations at the ATOLL platform (Atmospheric Observatory of LiLle), integrated into the European ACTRIS research infrastructure.
This synergy creates a powerful comparative framework and a rigorous testing ground for advanced source apportionment models. By exploring the variability between the temperate environment of Lille and the Mediterranean context of Marseille, the researcher will disentangle how distinct geographical and meteorological factors modulate the properties of emerging pollutants (UFP, BC). This cross-site approach ensures the robustness and representativeness of identified chemical fingerprints, providing a comprehensive understanding of aerosol sources across diverse regional scales.
Brief role description:
Main tasks
Under the supervision of the research team, the postdoctoral researcher will:
Set up, coordinate, and maintain high time-resolution monitoring stations in Lille and Marseille during dedicated measurement campaigns

Analyze particle number size distributions (UFP) and black carbon (BC) datasets, together with complementary aerosol data, to identify and quantify source profiles, for twin sites under the influence of traffic or not
Develop and apply advanced statistical and data-analysis methods for source apportionment, with support from senior researchers
Prepare scientific figures, technical reports, and peer-reviewed publications
Participate in project meetings, workshops, and conferences within the RESILIENCE consortium
Contribute to stakeholder engagement and dissemination activities, including interaction with air-quality agencies and local authorities
