Katherine Lee contributed to the UCD-SERG/serocalculator R package by developing simulation frameworks, refactoring plotting utilities, and improving code quality and documentation. She implemented a seroincidence simulation study to assess parameter impacts, using R and R Markdown for reproducible analysis and visualization. Her work included refactoring data handling for graph parameter generation, enhancing quantile calculations, and streamlining test automation with snapshot testing. Katherine addressed code linting, tidyverse alignment, and release engineering, ensuring maintainability and reliability. She also improved user experience through clearer documentation and plotting options, demonstrating depth in R programming, data visualization, and collaborative development within a research software context.

Apr 1, 2025April 2025 — UCD-SERG/serocalculator: Key features delivered, major bugs addressed, and overall improvements in reliability, testing, and release readiness. Highlights include a numeric quantiles refactor for Graph.curve.params with updated tests and snapshots, test scaffolding for figure updates, and release engineering work to prepare for the next version. Backward-compatibility was restored by reverting MCMC chain labeling to the original codebase. Code quality and tidyverse alignment were strengthened through tidyselect deprecation fixes, .data$ prefix removal, and comprehensive lint cleanups. Release readiness was enhanced with a version bump, NEWS updates, and acceptance of SVG asset changes, plus measures to silence R CMD check NOTES. These changes enhance graph accuracy, developer productivity, and business value by reducing maintenance overhead and speeding feature delivery.

Feb 1, 2025February 2025 monthly summary for UCD-SERG/serocalculator. Implemented a Seroincidence Simulation Study to evaluate renewal parameter impact (renew.params/renew_params) and CI visualization, extending the R package and delivering a comprehensive R Markdown report. The work establishes a reusable simulation framework to compare TRUE vs FALSE renewal settings across varying sample sizes, with bias, standard error, RMSE, and CI coverage summaries, plus visualizations of confidence intervals. This lays the groundwork for improved parameter tuning and more robust seroincidence estimates.
