Timothy Plummer developed and maintained advanced data processing pipelines for the IMAP-Science-Operations-Center/imap_processing repository, focusing on scientific data integrity and workflow reliability. He engineered robust modules for CDF file handling, geometric transformations, and calibration product integration, leveraging Python, NumPy, and SPICE Toolkit to support mission-critical backend workflows. His work included refactoring for maintainability, implementing vectorized algorithms for performance, and enhancing error handling and test coverage to reduce downstream risk. By aligning data models with evolving instrument definitions and improving uncertainty quantification, Timothy ensured high-quality, reproducible outputs that support complex astrophysics analyses and scalable science operations across the IMAP mission.

In August 2025, the sds-data-manager effort delivered a critical enhancement to the Hi L1B DE pipeline by introducing new data dependencies (l1b_hk and esa-energies) and applying them across both 45sensor-de and 90sensor-de configurations. This ensures all necessary data sources are recognized and available for processing, reducing upstream data gaps and enabling more complete L1B data products.
