PROFILE
Fabian Thiemann
During May 2026, contributed to the microsoft/mattersim repository by expanding MatterSim’s capabilities and improving its deployment and usability. Developed a Python-based MLIAP wrapper to integrate MatterSim with LAMMPS, enabling both single- and multi-GPU molecular dynamics simulations. Enhanced performance by refactoring threebody index calculations, reducing redundant computation and improving runtime efficiency. Introduced a Typer-powered command-line interface to streamline user and developer interactions. Delivered a GPU-enabled Docker image for LAMMPS and updated documentation to simplify containerized workflows. Focused on feature development, algorithm optimization, and infrastructure improvements, leveraging skills in Python, Docker, and GPU programming to support scalable, reproducible scientific computing.
