Worked on the FAIR-Chem/fairchem repository to enhance the stability and data integrity of its LAMMPS interface by addressing a critical issue in atom type extraction. Focused on refining the extraction logic so that only local atom types are considered, this change eliminated inconsistent mappings that previously affected simulation reliability. Leveraged Python programming and scientific computing skills to implement and validate the fix, ensuring that simulation inputs and downstream analyses are now more robust. The update reduced the need for downstream debugging and improved trust in automated pipelines, resulting in more reliable simulations and fewer user-reported issues related to data consistency.
