PROFILE
Giovanni Marchiori
Worked on the key4hep/k4geo repository to enhance detector geometry modeling and simulation reliability over a three-month period. Developed features such as configurable ECAL absorber materials and introduced new geometry definitions for the ALLEGRO detector, focusing on maintainability and alignment with evolving detector baselines. Improved geometry fidelity by refining XML configuration, updating detector metadata, and correcting geometry calculations for accurate simulation results. Implemented a cell size retrieval API across calorimeter modules, standardizing data access and supporting robust downstream analysis. Utilized C++, XML, and DD4hep, emphasizing code readability, maintainability, and precise geometry construction to support high-fidelity physics simulations and analysis workflows.
