Postdoc Multi-scale Modeling of Magma-Rock interactions in Subduction Zones M/F

Job Description

Missions

We are seeking a motivated postdoctoral researcher to join a project funded by the French Agence Nationale de la Recherche (ANR). The project aims to understand how liquids control deformation localization in the sub-arc mantle of subduction zones and to evaluate their implications for large-scale geodynamic evolution.
This postdoctoral position focuses on developing innovative numerical modeling, integrating machine learning (ML) and reduced-order models to bridge micro- to macro-scales. The project is led by Nestor Cerpa (CR, CNRS) nestor.cerpa-gilvonio@umontpellier.fr and involves collaboration with experts in geodynamics, petrology, and computational modeling, including Andrea Tommasi and Romain Tilhac at Geosciences Montpellier. Opportunities for collaboration with national and international partners are also available.

Activity

•Develop and train ML models to predict phase proportions of mantle rocks and magma content based on thermodynamic calculations
•Integrate ML models into reactive two-phase flow simulations
•Generate plausible dataset of models for reduced-order modeling
•Calibrate model results using natural analogs, particularly field data from exhumed subduction zone systems.

Your Profil

Skills

•PhD in geophysics, geodynamics, computational geosciences, or a related field.
•Strong background in numerical modeling, ideally with experience in ML applications
•Proficiency in scientific programming (e.g., Python, C++, or similar).
•Experience with high-performance computing (HPC) environments is a plus.
•Ability to work independently and as part of a team, with excellent communication skills.

Your Work Environment

Geosciences Montpellier is a leading research laboratory in Earth and environmental sciences, based in Montpellier, France. It is a joint research unit (UMR) affiliated with the CNRS (National Center for Scientific Research) and the University of Montpellier. The laboratory focuses on interdisciplinary research in geosciences, spanning topics around the dynamics of Earth's interior, the evaluation of geo-hazards, and the assessment of geo-resources.

This project is part of a collective effort to understand the interactions between liquids and rock deformation, with a particular emphasis on their implications for geodynamics. The project benefits from world-leading expertise in numerical modeling of Earth's interior.
The work will be carried out using various computing facilities, including the HPC center ISDM-Meso (Tier 2) and nationwide HPC centers (Tier 1).

The contract period will be 14 to 20 months, depending on experience
