Summary
👤
Senior🎓
Top SchoolBenjamin Stahl is an applied AI and data science practitioner with a PhD in Physics from UC Berkeley and a decade of experience turning noisy, large-scale datasets into decision-grade forecasts for high-stakes users. At Citadel he designed pipelines and models over 10¹¹+ rows that support 100+ investment professionals, emphasizing principled methodology, explicit uncertainty quantification, and operational robustness under time pressure. His academic work on exploding stars translated into order-of-magnitude gains in accuracy and a novel inference method that cut required data collection by ~90%, reflecting a talent for extracting signal from sparse observations. Now at Fundamental, he brings a rare blend of first-principles scientific training, rapid prototyping, and clear, context-aware communication that ensures models are trusted and acted upon.
