The project

This project is part of the EU-funded REWRITE initiative (https://rewriteproject.eu), which explores “rewilding” as a nature-based solution to restore and enhance the ecological resilience of Europe’s intertidal ecosystems. In REWRITE, our goal is to assess the capacity of intertidal microphytobenthos (MPB)—microscopic algae inhabiting the boundary between land and sea—to store "blue carbon" in diverse European mudflat ecosystems. To achieve this, we will integrate cutting-edge sediment diagenetic and MPB models with both field observations and remote sensing data.

We are seeking a highly motivated early-career researcher to focus on quantifying carbon fluxes and burial capacity, if any, driven by MPB using advanced numerical modeling. The researcher will couple a diagenetic model to an existing MPB model and refine the physical, biogeochemical and biological processes represented in the diagenetic model, with particular attention to improving sediment–water interactions in a tidal context. Building on recent progress of the host team in MPB modeling (Savelli et al., 2024), diagenetic and carbon cycle modeling (van der Zant et al., 2026), and in situ-derived organic carbon accumulation (Amann et al., 2026), the researcher will play a key role in advancing understanding of coastal biogeochemical dynamics.

The position offers the opportunity to collaborate with a dynamic, interdisciplinary, and international team of researchers and to take part in both national and international research initiatives.

The hosting laboratory

The researcher will be hosted at LIENSs, La Rochelle University, located in the coastal city of La Rochelle, France. LIENSs is an Interdisciplinary Joint Research Unit jointly operated by the French National Centre for Scientific Research (CNRS) and La Rochelle University. The laboratory focuses on the sustainability of coastal environments, which are increasingly vulnerable to the impacts of climate change and human activities. It brings together around 80 researchers, 29 permanent engineers and technicians, 24 postdoctoral and visiting researchers, and 40 doctoral students.

Employment

This is a full-time, fully funded position for a duration of 24 months, with an expected start date between July and September 2026.

If the candidate obtained his/her doctorate less than three years ago, a postdoctoral contract may be offered. After 3 years, an equivalent contract will be offered.
Please note: The post is located in a sector where scientific and technical potential is protected and therefore requires, in accordance with the regulations, that the arrival of the candidate recruited be authorised by the competent authority of the MESR.
