PROFILE
Peter Dong
During four months contributing to IMSA-CMS/CMSAnalysis, Peter Dong focused on improving C++ analysis workflows and code maintainability. He streamlined histogram retrieval by implementing direct access methods, reducing misreferences and runtime failures in data analysis modules. Peter also addressed a critical event-selection bug in the Lepton Jet Reconstruction workflow, ensuring accurate selector usage for physics analyses. His work included targeted code refactoring, such as removing redundant include directives to optimize build times and reduce header conflicts, as well as cleaning up non-essential logging to improve maintainability. Throughout, he demonstrated strong skills in C++, build system optimization, and software debugging.

Jan 1, 2026In January 2026, delivered targeted log cleanup in IMSA-CMS/CMSAnalysis to reduce console noise in histogram-related code paths. This involved commenting out non-essential log statements during histogram creation and when histograms are added, improving log readability and maintainability without altering functionality. No major bugs were fixed this month. Key commits: 6d3eedd2332120ff09d94cd305fd1057108e5fc9; fecd76f4175f4779633ea113e20facd46c8a88a4.

Aug 1, 2025August 2025 focused on correcting a critical event-selection bug in the Lepton Jet Reconstruction workflow within IMSA-CMS/CMSAnalysis. The fix ensures the reconstruction plan uses LeptonJetSelector instead of FakePhotonSelector, aligning event selection with physics intent and improving the accuracy of lepton-jet analyses. This work was accompanied by targeted commits and validation to prevent regression.

Jan 1, 2025January 2025 monthly summary for IMSA-CMS/CMSAnalysis: Delivered a fix to PlotFormatter histogram retrieval by direct access, simplifying the retrieval path and improving correctness of histogram data used in analyses. Eliminated the need to locate a process and then its systematic histogram, reducing misreferences and edge-case failures in the analysis module. This work improves reliability for downstream analytics and maintains alignment with existing workflows. Key commits implementing the changes are 8ade5bbfb88ce5f8f8776dee5693ab11539de80e and 1d20529f144be9896885f867bc37958f69a27eb5.
