Urban Air Quality and Atmospheric Chemistry

within a multidisciplinary project investigating the impacts of urban greening and mobility strategies on air quality. The recruited postdoctoral researcher will be responsible for conducting air quality measurements during field campaigns, with a focus on the organic composition of gas and particle phases, using state-of-the-art online instrumentation from the MASSALYA platform ( https://lce.univ-amu.fr/equipes/massalya ). Volatile organic compounds (VOCs) will be measured using PTR-ToF-MS, complemented by offline analyses. Aerosol physical properties (number and size distributions) and chemical composition will be characterised using a high-resolution aerosol mass spectrometer (HR-AMS) and the CHARON inlet coupled to PTR-ToF-MS, together with ancillary measurements (black carbon, NOx, ozone). The candidate will support instrument deployment and operation in close coordination with partner institutes, lead data analysis to quantify the impact of urban design and greening on air pollution and contribute actively to the dissemination of scientific results through publications in international peer-reviewed journals and presentations at international conferences. The candidate must have a PhD in atmospheric chemistry or physics, or engineering. This position is part of the OASIS-Urbaines project (funded by the ITEM Institute), a companion project of PEPR RESILIENCE ( https://pepr-vdbi.fr/projets/projets-resilience ), which focuses on sustainable and inclusive urban planning to improve well-being and environmental health. Whitin these two projects a transdisciplinary approach—including air quality, urban heat islands, greenhouse gas emissions, mobility, and biodiversity—will be deployed to evaluate urban greening policies under climate change. The final goal is to optimise greening and mobility plans to maximise co-benefits across these areas. OASIS-Urbaines combines field measurements and modelling at multiple scales to provide recommendations for local authorities and develop tools (maps, models, guides) to support policy and raise public awareness of the impacts of urban planning decisions. Requirements Research Field: Chemistry » Analytical chemistry Education Level: PhD or equivalent Skills/Qualifications PhD or equivalent in chemistry or physics. The candidate must hold at least a PhD in chemistry, physics or environmental sciences (atmospheric chemistry). Experience in VOC or aerosol measurements online mass spectrometry is required for this position, ideally during field campaigns. Skills in advanced statistics and automated data processing (preferably in Igor, Python and R programming language) are a prerequisite, due to the large amount of data that will be generated during the field campaign. Given the interdisciplinary nature of the project, the candidate must show ability to work with multiple research fields and institutions. Strong communication and organizational skills are thus essential to ensure the success of the project. Specific Requirements As the project is interdisciplinary, the candidate must be motivated and ensure that complementary areas of expertise are integrated in a balanced manner, regularly present their progress to the team and write scientific articles in English, demonstrate organization, listening skills, dynamism and communication skills and have a minimum B2 level of English. Experimental fieldwork requires being able to adapt and modify campaign dates according to unforeseen circumstances (weather conditions, instrument failure, etc.). The candidate must be flexible and available. Languages: ENGLISH — Level: Excellent Years of Research Experience: 1 - 4 Additional Information Benefits The candidate will be part of LCE in the IRA team, located within the St. Charles campus of Aix Marseille University, located downtown in Marseille. The candidate will be recruited at the LCE and will benefit from a reception office, a PC and all the needed support for the duration of the contract. The candidate will be under the supervision of B. D’Anna and J. Kammer (LCE), and will benefit from the support of engineers of LCE. The candidate will have access to the LCE's cutting-edge MASSALYA platform for VOC and particle measurements ( https://lce.univ-amu.fr/fr/equipes/massalya ).
