During February 2025, Simon Rionneau developed a unified parameter variation workflow for the DUNE/MaCh3_DUNE repository, streamlining systematic 2D and 1D scans through YAML-driven configuration. He consolidated multiple variation applications into a single, maintainable tool, refactored histogram retrieval logic in C++ for clarity and correctness, and enhanced configuration management to support reproducible, data-driven analyses. Simon also introduced atmospheric binning data assets to enable new analysis capabilities and resolved a histogram casting bug that previously caused runtime errors. His work demonstrated depth in build systems, code refactoring, and performance optimization, resulting in a more robust and maintainable analysis framework.
