During December 2025, Bertrand Thirion focused on enhancing developer documentation for high-dimensional inference methods in the lionelkusch/hidimstat repository. He improved clarity and usability for Desparsified Lasso and its clustered variants by refining code examples, correcting typos, and updating the changelog. Collaborating with Joseph Paillard, Bertrand ensured the documentation accurately supports researchers working with high-dimensional data analysis. His work, primarily in Python, emphasized data analysis, statistical modeling, and rigorous testing. By iteratively polishing documentation files, Bertrand reduced onboarding time and potential support issues, demonstrating depth in both technical communication and understanding of advanced statistical methodologies. No user-facing features were added.
