Summary
Joey Yu is a Member of Technical Staff at OpenAI with a decade of experience blending quantitative research and software engineering across top trading firms and tech internships. Trained at Waterloo (BS) and Carnegie Mellon (MS), Joey has moved from algorithm development and quant trading at HRT, DRW, Citadel, and Tower Research to applied AI work, bringing a probabilistic, experiment-driven mindset. He enjoys clever privacy-preserving protocols—evident from his interest in distributed statistics problems like ring-based averages and private medians—and describes himself playfully as a "professional coin flipper." Based in San Francisco, Joey excels at turning mathematical insights into production-ready systems and thrives at the intersection of algorithms, statistics, and scalable engineering.
