- DescriptionThe University of Bordeaux is a large, dynamic, and responsible university that prioritizes the well-being of its staff. Joining us means working in a privileged environment within a particularly diverse and open professional community, benefiting from onboarding and inclusion programs, training opportunities, and internal mobility. It means participating in an academic, scientific, and human adventure. It means committing to meeting the challenges of the 21st century.
Join the Oceanic and Continental Environments and Paleoenvironments (EPOC) laboratory at the University of Bordeaux!
This laboratory is a Joint Research Unit under the joint supervision of the University of Bordeaux, the CNRS (French National Centre for Scientific Research), Bordeaux INP (Bordeaux Institute of Technology), and the École Pratique des Hautes Études (EPHE).
EPOC is a multidisciplinary research unit developing strong and recognized expertise in ecotoxicology, ecology, biogeochemistry, environmental chemistry, sedimentology, paleoclimatology, coastal oceanography, and marine geosciences.
Within the framework of the ANSES EST 2025 RAS project, we are recruiting a Postdoctoral Researcher (M/F) whose work will focus on studying the efficacy, degradation, and toxicity of new biocide-free antifouling coatings for boats.
This project aims to characterize and compare the efficacy, degradation, and environmental risks of several new biocide-free antifouling coatings for boats using a multidisciplinary, integrative, and innovative approach.
Its objectives are, firstly, to address the lack of scientific data on the efficacy, durability, and ecotoxicity of these new materials; secondly, to develop and validate new approaches and tools for assessing the efficacy and risks of these products; and finally, to inform public policy regarding the selection of new, more sustainable boat coatings.
Your missionwill aim to study:
1. the antifouling properties
2. the resistance to photochemical degradation and friction
3. the ecotoxicity of 3 to 4 biocide-free antifouling materials using a multidisciplinary and holistic experimental and analytical approach.
# Study of the antifouling efficacy of three new coatings
: You will study the anti-adhesive efficacy against model bacteria under static and/or dynamic conditions, as well as against diatoms under static and/or dynamic conditions
. You will conduct a study of the anti-microfouling efficacy under natural conditions.
# Study of the kinetics and degradation state of the coatings under the action of UV light or an abrasion protocol
: You will perform irradiation in a UV chamber and abrasion with microbeads.
• You analyze surfaces using light and scanning electron microscopy
. • You analyze the state of degradation (oxidation, etc.) using infrared and Raman spectroscopy.
# Ecotoxicity study of coating leaching products
. • You prepare seawater leachates.
• You analyze their toxicity on 3 or 4 model marine species: bacteria, microalgae, microcrustaceans, and fish larvae.
• You perform chemical characterization of the particles present in the leachates using Raman microspectroscopy.
# Analysis and dissemination of results.
• You produce a statistical analysis of the results
. • You contribute to the writing of scientific articles
. • You present the results at scientific and public conferences.
- ProfileHolding a PhD in environmental sciences, specifically in ecotoxicology, microbiology, and analytical chemistry, you ideally have experience in biofilm analysis on plastic materials.
You are autonomous and organized in your work
. You demonstrate scientific rigor. You are
proficient in ecotoxicological, microbiological, and analytical chemistry techniques. You are skilled
in statistical analysis
. You enjoy working in a multidisciplinary team
. You are fluent in spoken and written scientific English in a multicultural work environment (level B2/C1).
