Amy Han developed an end-to-end competing risk model comparison framework for the zarathucorp/blog repository, leveraging R for data preprocessing, model evaluation, and statistical analysis. She implemented multi-metric performance evaluation, including Harrell’s and Wolbers’ C-index, AUC, and Brier scores, and enhanced melanoma survival analysis reporting through code refactoring and expanded metrics. Amy improved the clarity and usability of blog-based reporting by updating content and refining data visualization. She also maintained the blog site, resolving deployment conflicts and ensuring metadata consistency. Her work demonstrated depth in R programming, data science workflows, and web development, resulting in reproducible analytics and streamlined publishing.
April 2025: Delivered an end-to-end competing risk model comparison framework in R, including data preprocessing and performance evaluation (Harrell's C-index, Wolbers' C-index, AUC, and Brier scores), accompanied by multiple blog posts detailing methodology, results, and improved presentation of findings. Improved melanoma survival analysis reporting through refactoring and enhancements to R code for data processing, metrics, and results presentation within the blog post. Performed blog site maintenance and deployment updates, including asset changes, index alignment, and publication date consistency, and resolved site conflicts to improve reliability of releases. These efforts collectively advance decision-making through rigorous, reproducible analytics and clear stakeholder-facing reporting.
