Postdoctoral Researcher (M/F)

Descrizione

Postdoctoral Researcher (M/F) Sintesi in italiano (traduzione automatica): L'ente cerca un Ricercatore post-dottorato per studiare il ruolo dei fluidi nelle zone di subduzione, analizzando la loro composizione e evoluzione temporale. Il candidato lavorerà presso il laboratorio di ricerca ISTerre, affiliato all'Università di Grenoble Alpes, e collaborerà con il Principal Investigator Blandine Gardonio e un dottorando. Le mansioni principali includono lo sviluppo di approcci sismologici innovativi, l'analisi di terremoti ripetitivi e l'interpretazione dei risultati in relazione ai processi idrologici e geodinamici. È richiesta una laurea in geologia, geofisica o un campo correlato, oltre a competenze in analisi sismica e modellazione. Il candidato contribuirà anche alla diffusione scientifica dei risultati attraverso pubblicazioni e presentazioni. To study the role of fluids in the subduction zone by characterizing their composition and temporal evolution at the subduction interface and within the mantle wedge. To develop innovative seismological approaches to identify fluid signatures and better understand the mechanisms underlying seismicity. Identify and analyze repetitive earthquakes to study the temporal evolution of P- and S-wave arrival times (tS–tP) and their relationship to variations in water content. - Use seismic velocity models (Vp, Vs) and data from the literature to estimate the large-scale spatial distribution of water content. - Analyze seismic moment tensors from gCMT catalogs to characterize the source mechanisms of earthquakes. - Decompose the moment tensors into isotropic, double-couple (DC), and compensated linear vector dipole (CLVD) components to assess the influence of fluids on rupture mechanisms. - Interpret the results in relation to the hydrological and geodynamic processes in subduction zones and contribute to their scientific dissemination (publications, presentations). The candidate will work at the ISTerre research laboratory, a Joint Research Unit (UMR) comprising approximately 310 people and affiliated with the Observatory of Universe Sciences (OSU) at the University of Grenoble Alpes (UGA), which is responsible for numerous national observation services. The candidate will work in close collaboration with Blandine Gardonio (ANR Principal Investigator) as well as a student whose thesis will begin in September 2026. The candidate will be part of the “Seismic Cycle and Transient Deformations” team at the ISTerre laboratory. Annuncio in inglese. Fonte: Euraxess (Commissione europea).
