Yuan Yuan is a researcher-engineer bridging machine learning, causal inference, and network analysis with 13 years of experience across academia and industry. Currently a Member of Technical Staff at OpenAI and an assistant professor at UC Davis (formerly at Purdue), she focuses on computational methods for A/B testing, causal estimation, and the study of social and organizational networks. Her work blends rigorous field-experiment design with scalable ML tooling—evidenced by contributions to the ONNX project improving model type and shape representations. A Tsinghua-trained computer scientist with a PhD from MIT, she has applied her methods at Meta and Microsoft and has a track record of translating theory into practical systems for large-scale experiments. Colleagues describe her as equally at home writing production-grade model code and formalizing causal questions that drive real-world policy and product decisions.
