PROFILE
Valerio Pia
Over nine months, Valerio Pia developed and maintained core reconstruction features for the DUNE/sandreco repository, focusing on event vertexing, geometry processing, and robust CI/CD workflows. He implemented vertexing algorithms and integrated TrackerVertexing into the reconstruction pipeline, enabling new data outputs for downstream analysis. Using C++ and CMake, Valerio refactored geometry handling with BVH optimizations and improved error handling with modern C++ constructs. He stabilized build and test automation with GitHub Actions and Python environment management, reducing technical debt and improving reliability. His work emphasized maintainability, data integrity, and scalable detector configuration, supporting both current and future experimental requirements.

Jun 1, 2025June 2025 monthly summary for DUNE/sandreco focusing on delivering end-to-end vertexing capability and stabilizing reconstruction." Vertexing functionality was introduced by integrating the TrackerVertexing class into reconstruction, enabling vertex output and producing a new vertices branch in the dataset (commit c7d002a056f11c0507a30b21326b31adcf1ba684). In addition, key reconstruction correctness fixes were implemented to improve reliability and data integrity across all events: the initial state now uses the first trajectory point, and all events are processed with vector data structures maintained; this included fixes related to plane/hor handling in dg_wire to ensure correct plane association after plane rearrangement (commits 28cae9c5f059a4cea126e2efb7503f80f4376a93, b20e1639bc9084d152323e253167fd7255bca88a, 4e8bb933f1de1ac9779e1ae903ad120e40f0ea88). These changes collectively improve reconstruction fidelity and enable downstream physics analyses.
