PROFILE

Tracy Usher

During five months, Usher contributed to SBNSoftware and DUNE/dunereco by developing and refining data analysis and reconstruction tools for neutrino experiments. He enhanced space point reconstruction and bad-channel handling in SnippetHit3DBuilderSBN, improved detector geometry robustness, and overhauled hit finding by modularizing GaussHitFinder and introducing new data models in sbncode and sbnobj. Usher used C++, CMake, and configuration-driven controls to enable flexible, maintainable pipelines. His work included targeted bug fixes in icaruscode, improved build systems, and delivered the Cluster3D analysis tool for DUNE, supporting SPINE compatibility. The engineering demonstrated depth in modular programming, data processing, and scientific computing.

January 2025

1 Commits

Jan 1, 2025

January 2025 focused on stabilizing detector geometry handling in SBNSoftware/sbncode to ensure robust operation after larsoft v10 changes. The primary deliverable was a targeted bug fix: restoring the geometry service initialization that was lost during the v10 upgrade and updating the iteration over TPC identifiers to loop over TPC geometries for safer and more robust geometry data handling. This directly enables correct operation of SnippetHit3DBuilderSBN and improves downstream analysis reliability.
