During September 2025, H.J.Y. Zhang developed two new Jupyter notebooks for the tgstone/sio-math-workshop repository, focusing on practical statistics and time series analysis. Zhang applied Python, Pandas, and Matplotlib to create hands-on materials that illustrate concepts such as covariance, correlation, and cross-correlation, supporting both data analysis and educational objectives. The work included iterative content refinement, documentation cleanup, and removal of deprecated materials to ensure maintainability and clarity for workshop participants. By managing notebook lifecycles and aligning documentation with current content, Zhang delivered reproducible analytics resources and improved onboarding, demonstrating depth in both technical implementation and educational content development.
