Offer Description

The successful candidate will work within the framework of the ANR project MIRACLE, which aims to investigate the effect of uranium (U) speciation on the ability of bacteria to (bio)reduce U(VI) to U(IV).

Within this project, the objective of Subatech is to develop systems representative of environmental conditions, particularly with regard to uranium speciation in a wetland contaminated by the first uranium mining activities in France. This wetland is studied within the framework of the Zone Atelier Territoire Uranifère (zatu.org).

Beyond the chemical form of U(VI), particular attention will be paid to the lability of uranium complexes, i.e., the ability of chemical bonds to dissociate on short timescales.

The recruited candidate will perform laboratory experiments, and potentially fieldwork, to investigate the reactivity of U(VI) at both macroscopic and molecular scales.

The objective of this work will be to propose relevant model systems for studying microbial reduction processes in the presence of bacteria, by controlling uranium speciation and lability.

The candidate will also be expected to disseminate the results through scientific communications (conferences) and publications in peer‑reviewed journals.

The project is led by CEA‑BIAM and carried out in collaboration with the Helmholtz‑Zentrum Dresden‑Rossendorf (HZDR) in Dresden, Germany. Research stays in Germany are planned to perform spectroscopic studies.

The candidate should:

• Hold a PhD in radiochemistry, environmental chemistry, or a closely related field.
• Demonstrate strong motivation, scientific curiosity, and autonomy.
• Have a good command of scientific English (written and spoken).
• Be able to write scientific reports and present results orally.
• Be able to work both independently and collaboratively in an international research environment.
