George N. Wong
Worked on the IAS-Astrophysics/athenak repository, focusing on enhancing the correctness and reliability of scientific computing workflows in C++. Addressed critical bugs in binary I/O routines by ensuring that serialization functions accurately checked the number of bytes written, reducing the risk of data corruption and improving downstream data integrity. In later work, improved the accuracy and stability of magnetohydrodynamics (MHD) simulations by correcting Faraday contraction handling and time-centering in current output evaluations. Applied numerical methods expertise to refactor evaluation logic, align timing with derived outputs, and enhance reproducibility, contributing to more robust and maintainable research code in C++ environments.

Mar 1, 2026March 2026 performance summary for IAS-Astrophysics/athenak. Focused on stabilizing and improving the accuracy of the MHD JCON evaluation. Delivered a critical bug fix to Faraday contraction handling and time-centering, leading to more accurate current outputs in the plasma simulations. The change also aligns completed-step timing with derived outputs, refactors the evaluation to use midpoint-time spatial state and a consistent spatial stencil, and fixes Faraday index ordering. Result: higher numerical fidelity, more reliable long-running simulations, and improved data quality for research pipelines.
