PROFILE
Pablo Rf
Pablo Rodriguez-Fernandez led the engineering and ongoing development of the MITIM-fusion repository, building a robust simulation and workflow automation platform for fusion energy research. He architected and refactored core modules to support scalable, reproducible physics workflows, integrating tools like TGLF, CGYRO, and VMEC using Python and YAML-driven configuration. His work emphasized maintainability and reliability, introducing batch processing, job array support, and cross-platform compatibility. By modernizing data handling, automating experiment orchestration, and enhancing diagnostics and visualization, Pablo enabled faster iteration and more accurate analysis. He consistently delivered high-quality, production-ready code, balancing backend performance with extensible, well-documented interfaces.

Oct 1, 2025October 2025 MITIM-fusion development delivered several high-impact features, stability fixes, and backend modernization that collectively improve data processing reliability, visualization clarity, and maintainability. Key outcomes include an experimental ball workflow that reuses TGLF scans and enhances related prints; stability and NEO indexing fixes that reduce false positives and crashes; a migration of the GEQ reader to megpy with a staged deprecation plan for omfit_classes; a RAPIDS visualization improvement with vertical fG lines; and plotting improvements that disable fast gradients by default with a color override option. These efforts reduce risk, accelerate downstream analyses, and position the project for easier future maintenance and expansion.

Jul 1, 2025July 2025 MITIM-fusion monthly summary: Delivered a suite of feature-rich updates that strengthen core physics workflows, improve data handling, and reduce maintenance risk. Key features include Stellarator profiles with VMEC state handling and geometry plotting, a robust PORTALS/TGLF workflow without TGYRO using real TGLF settings, and standardized input conventions for gacode mass initialization with a Deuterium reference. Additional enhancements cover plotting improvements (including 3D tokamak visualization), expanded VMEC interpretation for broader compatibility, and targeted refactors and API cleanups (to_tglf, turb/NEOC/Ge/GZ naming). Major cleanups include removal of deprecated portals functions and unused particle flux metrics. Major bugs fixed span naming and numerical robustness across the TGLF path and data comparisons. Overall impact: more reliable, reproducible physics runs; clearer API and data conventions; reduced technical debt; and a stronger foundation for future releases and UQ integration.

Nov 1, 2024In November 2024, MITIM-fusion delivered stability-focused feature work, targeted bug fixes, and foundational work enabling longer-term integration and automation of research workflows. Key deliverables include workflow and PORTALS configuration enhancements that stabilize opt workflow, integrate PORTALS with non-default kwargs, add SLURM exclusivity to the config, and refine acquisition defaults; these changes improve automation reliability and experiment consistency. Early Maestro integration was kicked off, with TRANSP Globus run support validated and TORIC-related fixes continuing, establishing a foundation for broader orchestration across tools. The team also performed targeted maintenance and refactors (ASTRA-related changes under review) and completed test-suite cleanup (removing outdated EPED NN opt tests and renaming restart alias to cold_start) to improve test relevance and reliability. Extensive bug fixes touched critical areas including training trigger logic when BO_iterations = 0, initialization reading, namelist writing, globus handling, MAESTRO issue resolution, SLURM submitter stability, path handling, and misc cleanup, resulting in fewer failures and more deterministic runs. Supporting work strengthened core reliability and portability, with path resolution hardening (ExpandPath), environment-variable handling improvements, deterministic seeding, 8-thread test configuration, pickle protocol upgrade to 4 for MITIM, and generalization of Torch device handling and remote file retrieval. Overall impact: improved stability, reproducibility, and scalability of MITIM workflows, enabling more efficient research and easier future feature integration.
