Job description

The Laboratory of Plasma Physics, Paris, France, is opening a two-years postdoctoral position to work on the development of large scale fluid/Particle-in-Cell numerical modeling of the Earth's magnetosphere.

Large scale space plasma systems are challenging to model numerically due to the collisionless nature of the plasma dynamics. Typically, computational load reduction in multiscale systems is achieved either through adaptive mesh refinement or by simplifying the physical models, often replacing kinetic equations with fluid approximations.
Our approach, called Adaptive Mesh and Model Refinement (AM2R) integrates these strategies into a single code, allowing the finest physics and resolutions to be employed only where and when assessed necessary.

As a postdoctoral fellow, you will join a small happy development team composed of two permanent researchers, a HPC engineer, a PhD student, and contribute to the development of the code PHARE. More specifically, you will add the planetary magnetic field and boundary conditions as well as those for the solar wind, in the finite-volume Godunov Hall-MHD part of the code and participate to the first global magnetosphere models combining this Hall-MHD solver with the already existing AMR Hybrid Particle-In-Cell one.

Qualifications

  • A PhD in physics, computational physics, or applied mathematics.
  • Proficiency in modern C++ and Python is essential.
  • Experience in high-performance numerical modeling, and in particular in contributing to large HPC codebases is advantageous.
  • Familiarity with open-source development workflows (e.g., GitHub) is appreciated.

Work environment and salary

You will work at the Laboratory of Plasma Physics, located in the campus of Ecole Polytechnique, in the Paris area, alongside with the other team members.

You will join the space plasma team of the lab, where research is performed on all major space plasma topics, using spacecraft data analysis, theory and numerical modeling.

Besides your own workstation, you will have access to the labs HPC resources, local mesocenters and national supercomputers on which the team has computing hours.

The gross income is about 3200€/month.
