PROFILE

Connor Mcclellan

Worked on the tardis-sn/tardis repository to deliver core simulation features and improve data reliability. Developed a data migration workflow that converts legacy atomic data to the TARDIS format, using Python, Pandas, and HDF5 for robust file handling and user guidance via Jupyter notebooks. Implemented a non-homologous transport mode with a generalized distance solver and Numba acceleration, refactoring geometry routines for numerical robustness. Addressed data integrity by fixing LastInteractionTracker bugs, aligning tracker fields, and enhancing regression test accuracy. Expanded test coverage and improved maintainability, ensuring compatibility with existing workflows and supporting accurate astrophysical modeling and efficient research iteration.
