PROFILE
Han Yang
Over two months, contributed to the microsoft/mattersim repository by delivering five features and resolving two bugs focused on simulation reliability and developer experience. Work included refactoring model loading logic in Python to remove deprecated paths, standardizing stress and pressure units to GPa for improved scientific accuracy, and expanding documentation for easier onboarding. Modernized DeepCalculator integration and introduced a deprecation path to MatterSimCalculator, ensuring backward compatibility while guiding users to updated APIs. Enhanced CI/CD pipelines using GitHub Actions and automated packaging with tools like cibuildwheel, streamlining releases and dependency management. Skills applied included Python, shell scripting, build automation, and scientific computing.

Nov 1, 2024In 2024-11, Microsoft Mattersim delivered key features and reliability improvements with a focus on runtime correctness, developer experience, and onboarding. Major work included: 1) Model loading cleanup and deprecation removal to simplify the loading path and align behavior with the README; 2) Unit standardization to GPa for stress and pressure calculations using ASE, raising accuracy and interoperability; 3) Documentation and installation improvements to streamline setup (PyPI, GitHub pip install, conda) and provide clearer device usage guidance. These changes reduce maintenance burden, improve numerical fidelity, and accelerate user adoption. Business value: more robust simulations, fewer edge-case failures due to deprecated paths, and faster ramp-up for new users. Technical highlights: code refactors for loading, unit conversion updates, and expanded docs with updated examples and setup steps.
