PROFILE
Eliza Neights
Over nine months, contributed to the cositools/cosipy repository by developing advanced polarization analysis features, robust data handling, and reproducible scientific workflows. Leveraging Python, Jupyter Notebooks, and scientific libraries such as NumPy and Astropy, implemented end-to-end polarization support, maximum likelihood fitting, and spectral analysis pipelines for astrophysical data. Enhanced code reliability through expanded unit testing, continuous integration with GitHub Actions, and targeted bug fixes. Improved user onboarding and documentation clarity, particularly for spectral fitting and polarization tutorials, while refactoring plugins and analysis modules for maintainability. These efforts enabled more accurate astrophysics modeling, streamlined analysis, and reduced manual debugging for users.
