Summary
👤
Senior🎓
Top SchoolJulien Guénolé is a CNRS Chargé de Recherche and group lead with nine years of experience at the intersection of physics, mechanics and materials science, specializing in atomistic modeling of mechanical properties and irradiation damage. He combines high-performance computing and large-scale data management with hands-on code development, contributing upstream to flagship open-source projects such as LAMMPS to improve minimization and box-relaxation routines. Julien has led research teams in competitive academic settings (RWTH Aachen, Erlangen-Nuremberg) and supervised trained collaborators to successful outcomes, demonstrating both project leadership and deep technical craftsmanship. Based in Metz, France, he holds a PhD in Condensed Matter and Materials Physics and brings a practical focus on reliable, reproducible simulation workflows that bridge theory and experiment.

Mar 2018 - Mar 2020
Public development project of the LAMMPS MD software package
Role in this project:
Back-end Developer
Back-end DeveloperContributions:37 commits, 3 PRs, 14 comments in 1 year 11 months
Contributions summary:Julien primarily contributed to the `min_adaptglok.cpp` file, implementing and refactoring methods related to box relaxation within the LAMMPS molecular dynamics software. These changes included initializing and setting up the relaxation parameters, adding checks for neighbor builds, and zeroing velocities during the box relaxation process. Furthermore, the user corrected default values and fixed integration schemes for the fire2 style in `src/min_fire.cpp`. The commits reflect efforts to improve the minimization capabilities of the LAMMPS package.
