PROFILE
Vivienne Uenuma
Vuenuma contributed to the IMSA-CMS/CMSAnalysis repository by developing features that enhanced data analysis workflows in particle physics. Over five months, Vuenuma implemented systematic uncertainty handling, 2D histogram visualization for mass versus eta and pt, and tau lepton support in the analysis framework. Using C++ and leveraging skills in data analysis and statistical modeling, Vuenuma standardized file naming conventions to improve data governance and reproducibility. The work included building utilities for configuration-driven fit validation and refining ROOT I/O handling. Each feature was integrated with attention to code cleanliness and maintainability, resulting in robust, testable solutions for scientific computing challenges.

Nov 1, 2025November 2025 (Month 2025-11): Delivered systemic uncertainty handling in the CMSAnalysis project by extending FitTest and FitFunction to support systematic variations (up/down) of fit parameters and to list/manage systematics. This enhancement enables more robust uncertainty quantification, improves the reliability of physics analyses, and enhances reproducibility across runs. No major bugs reported this month; the focus was on feature delivery and clean integration with the existing analysis workflow. The work strengthens business value by enabling more accurate uncertainty estimates in results and reducing potential biases in fits.
