PROFILE
Rodrigo Neumann
Worked on the IBM/materials repository to deliver advanced features for materials science modeling, including enhancements to the POS-EGNN core model and the introduction of Raman spectra prediction based on crystallographic data. Leveraged Python, PyTorch, and Jupyter Notebooks to implement deep learning workflows, improve model deployment, and streamline data processing. Focused on reproducibility and maintainability by expanding documentation, upgrading dependencies, and preparing the codebase for arXiv submission. Addressed stability by refining device initialization and import handling, ensuring consistent graph neural network operations. The work emphasized clear documentation, robust packaging, and direct model checkpoint distribution to support research and production use.
