Worked on enhancing the ProtoDUNE VD cosmic simulation configuration within the DUNE/dunesw repository, focusing on improving model fidelity and validation readiness. Updated FCL configuration files to adjust quantum efficiency and scintillation pre-scale values, directly impacting simulation accuracy and reproducibility. Emphasized clear commit traceability and thorough documentation to support future development and review processes. Applied skills in data analysis, scientific computing, and simulation configuration to lay the groundwork for more robust simulation workflows. The work addressed a targeted feature rather than bug fixes, reflecting a focused and methodical approach to advancing simulation capabilities in a collaborative research environment.
