During December 2024, Eilis Hannon enhanced two repositories by delivering four new features focused on data accuracy and advanced analytics. In the CfRR_Courses repository, Eilis refreshed the About Us page and updated documentation to streamline user feedback and acknowledge contributors, emphasizing clear communication and data governance. For the BrainFANS repository, Eilis improved the sex prediction algorithm by introducing custom thresholds and mixture models, enabling robust handling of single-sex datasets and enhancing reporting with updated summaries and visualizations. These contributions leveraged R, Jupyter Notebook, and statistical modeling, demonstrating depth in bioinformatics, data preprocessing, and documentation within a collaborative research environment.
