Taejun Ryu enhanced the OpenFUSIONToolkit/JPEC repository by developing robust plasma equilibrium processing and stability analysis workflows. He integrated Fourfit with JPEC to enable accurate extraction and spline representation of magnetic field data from EFIT g-files, using Julia and Fortran for numerical routines and data analysis. Taejun refactored and expanded spline functionality, improved Fourier coefficient extraction, and optimized DCON workflows for MHD stability assessment, consolidating notebook-driven analyses into cohesive, validated pipelines. His work included dependency management, legacy code removal, and matrix validation, resulting in reproducible, maintainable scientific computing tools that support advanced plasma physics simulation and equilibrium reconstruction tasks.
