A postdoctoral or engineer position is offered at Aix-Marseille University in population genomics focusing on the role of adaptive introgression for the persistence of marine and terrestrial biodiversity in a context of coastal pollution by past industrial activities. The project HYAM (for “Hybridization and Adaptation in a Mediterranean coastal city”) is funded by the A*Midex foundation and started in 2024. HYAM is led by Alex Baumel (IMBE laboratory) and Didier Aurelle (ISYEB laboratory) and brings together several teams offering rich and enthusiastic collaborations at the frontiers of evolutionary biology, ecology, and conservation of biodiversity. Activities: The selected candidate will be responsible for analysing reduced and whole genome sequencing data, and screening their diversity to detect introgression and selection marks. The data will be acquired, allowing the analyses to start as soon as the contract begins. The contract will be focused on octocoral populations. The project will involve a collaboration with the Calanques National Park. The candidate will benefit from an initial phase of environmental characterization and assessment of the genetic diversity structure of the studied organisms, and of the supports of high-performance computing clusters of OSU Pytheas and IFB. Requirements for the position: The candidate must have a strong background in bioinformatics and population genomics. Experience in the analysis of whole genome data and evolutionary inferences would be an advantage. The candidate must be fluent in written and spoken English. The candidate must not have completed his last degree at Aix-Marseille University. Contract: The contract is for 12 months. The expected starting date is 4 January 2027. Applications must be sent to alex.baumel@imbe.fr and didier.aurelle@univ-amu.fr with CV, covering letter, list of publications, and the email of two referees, from April 1st and no later than June 1st. The selection of candidates will be carried out by a committee from the HYAM project and based on CVs and interviews by videoconference and possibly in person.
