PROFILE
Sofia Giappichini
During their two-month contribution to the KIT-CMS/CROWN repository, Simone Giappicchetti enhanced the physics correction workflow and improved Z boson analysis reliability. Using C++, Python, and the ROOT framework, Simone implemented robust error handling, edge-case parameter checks, and year-specific logic to increase simulation fidelity and maintainability. They modernized pileup weight handling by introducing a ROOT-based reader, streamlined configuration management with cumulative sample type flags, and refactored code for clearer parameter handling. These updates reduced edge-case failures, improved uncertainty estimation, and simplified future extensions, demonstrating a thoughtful approach to backend development and scientific computing within a complex research environment.
