Christian
I am a Computational Geoscientist at the University of Lausanne developing scalable high-performance solvers for geodynamic modelling. My previous work explored the dynamics of interacting subduction zones and associated plate motion in the Mediterranean, while contributing to the development of computational tools for geodynamic applications using automatic differentiation and Julia.

JustRelax.jl (de Montserrat et al., (2026)) is an open-source, highly portable, and high-performance package designed for geodynamic modeling. It employs the Accelerated Pseudo-Transient (APT) method to solve the Stokes and diffusion equations, making it well-suited to exploit Graphics Processing Units (GPUs). It incorporates a wide range of features critical to computational geodynamics, including complex and highly non-linear rheologies, free surface, and a particle-in-cell method to advect material information.
