Researcher

Patrick Rebeschini

Rebeschini earned a Princeton doctorate in operations research and financial engineering and held Yale research appointments before Oxford. His research combines probability, statistics and optimization. His work includes model aggregation, learned feature geometry and contextual bandits. These study how learning methods use data and generalize, with mathematical assumptions stated in the papers. He coauthored Knowing When to Quit, an ICML 2026 study on dynamic abstention in language-model reasoning. This connects decision rules with reliable model behavior.
