Postdoctoral Position in Evolutionary Genomics and Climate Resilience We are seeking a highly motivated Postdoctoral Researcher to join the GRACE project, investigating evolutionary and genomic responses to climate change in marine species. The successful candidate will lead genomic analyses of natural populations using SNP arrays and low-coverage whole-genome sequencing (lcWGS). They will analyze population structure, genetic diversity, and signatures of selection, and integrate genomic data with experimental phenotypes such as survival, behavior, and condition index. The postdoc will also contribute to the design and analysis of transgenerational plasticity (TGP) experiments and collaborate closely with an interdisciplinary team of scientists within the GRACE consortium. Project context: Climate change, particularly rising temperatures, is rapidly altering ecosystems worldwide, with profound effects on biodiversity. Species living near their thermal tolerance limits are especially vulnerable, leading to shifts in distribution, behavior, and ecological interactions. The GRACE project focuses on two sentinel species the blue mussel (Mytilus edulis) and the copepod (Eurytemora affinis) to understand the genomic and phenotypic mechanisms that underlie thermal resilience. These species are key components of marine and estuarine ecosystems in the Normandy region and serve as excellent models for studying adaptation to climate change. Using a combination of population genomics, controlled heat-stress experiments, and transgenerational assays, the project aims to identify the molecular and phenotypic bases of thermal tolerance and adaptive potential.
