Background

Oniris, LABERCA, France, is offering a 2-year postdoctoral contract in the field of analytical chemistry applied to the characterisation of organic contaminants in an interdisciplinary context integrating the food, circularity and environmental dimensions.

The work is part of two collaborative National and European research projects:

• TWINLOOP (ANR project, 2025-2029, 21 partners), focused on the characterisations of chemical contaminants in plastics intended for food contact recycling processes, using a variety of techniques.
• PARC (EU Horizon EU Cofund, 2022-2029), sub-project P4.3.3.b_Y2_E02-Sentinel animals_ONIRIS (15 partners) investigating animal species as sentinels of the environment and human chemical exposomes.

Main missions

• Development and application of non-targeted analytical methods (LC/IM/HRMS, timsTOF Pro II) for the detection and characterisation of organic contaminants in various matrices (plastics, bees, aquatic invertebrates).
• HRMS data acquisition and annotation, assessment of exposure profiles.
• Participation in the analysis of the chemical exposome within an interdisciplinary framework.
• Drafting scientific reports, contributing to the writing of articles and promoting results of the projects.

Candidate profile

• Strong chemical background with a PhD in Analytical Chemistry or equivalent.
• Hands on experience with analytical method development and advanced data analysis within chromatography and HRMS workflows.
• Experience or knowledge about chemical contaminants, food safety and exposome.
• Good collaboration and communication skills (written and spoken English).

Working environment

The post-doctoral fellow will join a dynamic team in a recently renovated and very well-equipped laboratory, with more than 25 mass spectrometers using a variety of technologies (Orbitrap, QTOF, IMS, GC-MS/MS, LC-MS/MS, etc.). Based in Nantes, France, LABERCA offers a stimulating environment at the interface between academic research and public expertise.

Application

Applications must be submitted to ronan.cariou(at)oniris-nantes.fr as one pdf file containing all materials to be given consideration. The file must include, a cover letter, a curriculum vitae and supporting letters. before February 3, 2026

Contexte de travail

LABERCA (Laboratory for the Study of Residues and Contaminants in Food) is offering a postdoctoral is offering a postdoctoral contract for 1 year in the framework of PARC project.
Partnership for the Assessment of Risks from Chemicals (PARC) aims to develop next-generation chemical risk assessment to protect human health and the environment. It supports the European Union's Chemicals Strategy for Sustainability and the European Green Deal's “Zero pollution” ambition with new data, knowledge, methods and tools, expertise and networks.

The PARC programme has three main objectives:

• Develop the scientific skills needed to address current and future challenges in chemical safety
• Provide new data, methods and innovative tools to those responsible for assessing and managing the risks of chemical exposure
• Strengthen the networks which bring together actors specialised in the different scientific fields contributing to risk assessment

Main missions

• The 12 months position aims to contribute to the development of a new analytical method for PFAS suspected screening on human serum samples. The contribution will cover all stages of the method, from the preparation of human serum samples to the optimisation of mass spectrometry analyses, including non-targeted analytical processing workflows for application to human biological samples..

Candidate profile

• PhD in analytical chemistry.
• Strong expertise in mass spectrometry (especially HRMS) and both targeted and nontargeted approaches.
• Experience with complex data processing (software such as Compound Discoverer, MZmine, Skyline, etc.) is a plus.
• Strong interest in exposome research, chemical safety, and interdisciplinary science.
• Team-oriented, autonomous, and scientifically rigorous.

Working environment

The postdoctoral researcher will join a dynamic team within a recently renovated and fully equipped laboratory, with over 25 mass spectrometers of various technologies (Exactive, QTOF, IMS, GC-MS/MS, LC-MS/MS, etc.). LABERCA provides a stimulating research environment at the interface between academic research and public expertise.

Application

Send your CV, cover letter, and if possible, two letters of recommendation (combined into a single PDF file) to: ronan.pommereuil(at)oniris-nantes.fr, before August 15, 2025
