La sismicité et la tectonique active ont-elles influencé les migrations des hominidés en Asie centrale depuis la fin du Pléistocène ? Le cas du nord du Tien Shan // Did active tectonics and seismicity shape hominid migrations in Central Asia from Late Ple

Active tectonics have a lasting influence on landscapes and constitute a major factor in the mobility, settlement, and dispersion of human populations. By altering hydrological networks, landforms, and shelter possibilities, seismic activity directly affects settlement conditions on timescales compatible with the evolution of ecosystems and human societies. The proximity of water resources, essential for habitation sites, is particularly sensitive to tectonic deformations, while major earthquakes (Mw 6 to 8) can lead to the destruction of sites and cause population displacements. In orogenic contexts, the interactions between tectonics and climate amplify these effects, with the terrain controlling both precipitation patterns and ecosystem diversity.

Nous recherchons un(e) candidat(e) très motivé(e) ayant une formation en sciences de la Terre, avec de solides compétences en tectonique. Alternativement, le(a) candidat(e) pourrait avoir une solide formation en archéologie des hominidés, avec des compétences complémentaires en géophysique et en géologie. Le(a) candidat(e) devra être à l'aise avec le travail sur le terrain, en équipe et les collègues issus de divers domaines (sismologie, archéologie, tectonique, etc.), dans le cadre général des laboratoires ISTerre et Zoostan. Il/elle devra montrer un fort intérêt pour la coopération internationale, notamment en Asie centrale. Il/elle doit avoir un haut niveau d'autonomie et une bonne capacité de mobilité dans divers environnements, y compris lors de missions de terrain dans des conditions difficiles. Des compétences en programmation Python ou Matlab sont nécessaires pour la gestion des données. Un bon niveau d'anglais (oral et écrit) est requis.
We seek a very motivated candidate with a background in Earth sciences, with strong skills in tectonics. Alternatively, the candidate could have a strong background in hominid archeology, with side-skill in geophysics and geology. The candidate will be at ease with team-work, and colleagues from a variety of fields (seismology, archeology, tectonics, etc.), within the general framework of ISTerre and Zoostan laboratories. He/she will have a strong interest for international cooperation, specifically in Central Asia. He/she must have a high level of autonomy and mobility capability in various environments, including remote field missions in harsh conditions. Skills in Python or Matlab programming are necessary for data handling. A good level of English (spoken and written) is required.
