Rhys Goodall is a machine-learning-driven materials scientist and Member of Technical Staff based in New York with nine years of interdisciplinary experience applying ML to targeted materials discovery and battery R&D. He developed influential frameworks (Roost and Wren) during his PhD at Cambridge and has published in high-impact journals while bridging academic research and industry productization. At Chemix he built custom AI models for accelerated battery development, and at Radical AI he continues scaling ML for materials problems. An active contributor to the widely used pymatgen project, he has improved phase diagram tools and Voronoi neighbor calculations—work that demonstrates attention to numerical stability in scientific software. Trained in physics with business and battery-specialist credentials, he combines deep domain knowledge with practical engineering to move models from research into real-world discovery workflows.
