Post-Doctoral position

The CARRTEL (INRAE/USMB) laboratory is a research laboratory whose scientific work is dedicated to the study of lake ecosystems and their biodiversity through both fundamental and applied approaches. The proposed postdoctoral mission is part of the research of the BIOTIC thematic axis, one of the three thematic axes of the CARRTEL

laboratory. Research in this thematic axis focuses on the integration of diversity and the role of biotic interactions on lake ecosystem functioning and on understanding the responses of lake ecosystems to multiple pressures at both local and global scales.

The EDYTEM (CNRS/USMB) laboratory is an interdisciplinary laboratory that addresses environmental issues in an integrated. The proposed postdoctoral mission is part of the research of the MATIERES team, one of the four teams of the EDYTEM laboratory. The team's research focuses on materials of economic and/or cultural interest, in other

words, materials voluntarily used and/or transformed by humans, whether natural or synthetic. From fundamental to applied, the team is interested in the processes and/or processes of transformation of these materials (synthesis,formation, functionalization, shaping, alteration, aging, degradation) using different resources (organic, mineral, or metallic) through the study and elucidation of different mechanisms (reactivities, interactions). The team is particularly recognized at the national and international levels for its work in green chemistry, biomass valorization, and waste management, as well as in the use of non-conventional activation methods in the developed processes.

The quagga mussel (Dreissena bugensis) is an invasive bivalve causing significant nuisance for a range of uses associated with the exploitation of aquatic ecosystems. Literature suggests that the establishment of juvenile stages could involve chemical communication with adults fixed to the substrate. The research objectives will be to identify

molecules produced by adult mussels with attraction capabilities on juveniles and to develop chemical formulations optimizing juvenile attraction. These innovative research efforts are part of a strong socio-economic demand underpinning major operational and scientific valorizations.

The postdoctoral researcher will be integrated into a multidisciplinary research team including researchers in chemical ecology, organic chemistry, and aquatic ecology. Access to an analytical chemistry platform (GC-MS, UPLC-DAD, LC-MS-MS) will be provided. A dedicated breeding facility for quagga mussel reproduction will supply juvenile mussels for attraction tests.
