PROFILE

Aaronkho

Worked on the MITIM-fusion and google-deepmind/torax repositories, delivering features that modernized codebases and improved scientific workflow reliability. Introduced pathlib-based path handling and refactored file operations to enhance cross-platform compatibility, while standardizing remote and local execution semantics to reduce environment-related failures. Integrated FiBE-based equilibrium initialization and expanded plasma parameter support for more accurate power state calculations. Developed a TGLF transport model interface for the TORAX simulator, enabling automated core transport simulations. Leveraged Python, PyTorch, and JAX to streamline data processing, dependency management, and simulation workflows, resulting in more maintainable, reproducible, and automation-ready scientific computing environments.

Dec 1, 2025

December 2025: Delivered the TGLF Transport Model Interface for the TORAX Simulator (google-deepmind/torax). This feature adds an interface to execute the TGLF transport model within TORAX, enabling automated and reproducible tokamak core transport simulations and reducing manual setup. The work strengthens core transport modeling capabilities and lays groundwork for broader transport-model integrations. No major bugs reported this month; focused on feature delivery and integration with existing TORAX APIs.

October 2025 MITIM-fusion: Implemented FiBE-based equilibrium initialization in MAESTRObeat, including initializer_from_fibe to generate equilibrium data via FiBE and convert to geqdsk for downstream processing. Stabilized build and runtime by aligning dependencies: switched fibe to main branch and updated megpy/fibe to PyPI releases; re-added FiBE installation dependency. No major bugs fixed during this period. Overall impact: enabling repeatable, FiBE-driven equilibrium initialization for faster scenario setup and smoother downstream workflows; improved build reproducibility and maintainability. Technologies: FiBE, fibe, PyPI releases, geqdsk conversion, MAESTRObeat.

March 2025 monthly summary for pabloprf/MITIM-fusion: Implemented Power State Calculation Enhancement by expanding the plasma parameter set and improving IMAS-to-CGYRO data normalization. Key changes include adding B_unit, q, s_q, aLTe, aLTz, ne, nZ, w0, B_ref, Zeff, kappa, delta, and betae; and removing a commented eps line to enhance accuracy and flexibility. Re-added B_ref to satisfy downstream usage and maintain CGYRO compatibility, enabling more accurate power state calculations and broader parameter coverage.

November 2024 MITIM-fusion: A focused sprint delivering broad pathlib migration, cross-platform hardening, and user-input robustness across the repository. Achievements include migrating TGLF workflows and remaining tools to pathlib, refactoring modules to reduce os.path usage, replacing system commands with shutil, and introducing Python-based translation for IOtools. Windows input support was added, and key bug fixes improved parsing and portability. These changes enhance portability, reliability, and maintainability while delivering measurable business value in automation-readiness and developer productivity.

MITIM-fusion – Monthly summary for 2024-10 Overview: - Focused on robustness, portability, and execution reliability across FARMINGtools, TGYROtools, TGLFtools, and GACODE run utilities. Delivered concrete path handling modernization, execution-mode hardening, and a critical device-placement fix to stabilize optimization work. Key features delivered: - Path Handling Modernization Across Core Tools: Adopt pathlib-based path handling across FARMINGtools, TGYROtools, TGLFtools, and GACODE run utilities to improve robustness, readability, and consistency when constructing and validating file paths. Representative commits: 5d39ddfff4e067282ae498f72ba7da094c260fe1 (Update remaining pieces of FARMINGtools to pathlib), a459e86c4cd981d7a31345781290bbd4d7a7b32b (Additional progress on TGYROtools conversion), aa6269d46d792d883c42de6f56868ff79d46fffd (Finish update of TGYROtools to use pathlib), bece74c8f2d0387fa9718b21fbc13809615726f4 (Avoid spinning up nested shells via bash command, can break virtual envs), ab38ff236f5ca0c671ea7726fdb1d53cd832d3a4 (Minor fix to TGLFtools to ensure input is a Path object), 6adcbb2afa1f3b653abfbff991f19da9cb3249ba (Update runTGLF function in GACODErun to use pathlib). - Remote/Local Execution and Shell Execution Robustness: Standardize local vs remote job execution behavior, remove default bashrc sourcing in remote environments, and ensure shell commands execute directly to avoid nested shells and environment conflicts. Representative commits: 78767181e87e21bec11521cfb661d272e6a1f435 (Remove extra default sourcing of bashrc for remote jobs), f7b6c6919ebc97d83be9d1109044de2da914fe7b (Assume clear distinction between remote and local in FARMINGtools), 89808616e84b6c80fa4256c67745249316764720 (Revert changes related to remote path in FARMINGtools, left as string). - Device Placement Stability in Optimization: Fix runtime stability by ensuring tensors are moved to the correct device (CPU/GPU) during transformations and predictions. Representative commit: 2bab22ff2867ba987cc11af5535d60f9a2fb9c1e (Improve consistency of dtype and device in optimization classes). Major bugs fixed: - Ensured tensors are consistently placed on the correct device (CPU/GPU) during optimization transformations and predictions, improving runtime stability and reproducibility. Overall impact and accomplishments: - Business value: More reliable build and run pipelines, fewer environment-related failures, and improved reproducibility across end-to-end workflows for MITIM-fusion. - Technical impact: Clean, portable path handling; robust remote/local execution semantics; and safer tensor device management that reduces mystery errors in production runs. Technologies/skills demonstrated: - Python pathlib for file system paths; cross-tool standardization; remote/local execution patterns; shell command safety (avoiding nested shells); PyTorch device management and dtype handling.
