Yuan Yuan is a Member of Technical Staff at OpenAI and an assistant professor at UC Davis with 12 years of experience bridging machine learning research and causal inference. He develops computational techniques that combine ML and causal methods for online field experiments (A/B testing) and uses large-scale data to study social and organizational networks. Trained at MIT (PhD) and Tsinghua (BS in CS and Economics), he has held roles at Purdue, the MIT Media Lab, Microsoft, and Meta, moving fluidly between academia and industry. Beyond academic work, he contributes to core ML infrastructure—e.g., meaningful ONNX changes to onnx.proto and LSTM/type-shape handling—highlighting a rare ability to translate rigorous causal methods into production-ready tooling. Based in San Francisco, he’s known for turning principled statistical ideas into scalable experimental and network-analysis systems.

Contributions:52 commits, 16 PRs, 59 pushes in 3 months
Contributions summary:Yuan's commits primarily focused on modifications to the `onnx.proto` file and related Python helper functions. The changes involve restructuring data types, shapes, and value information within the graph representation used by ONNX. The contributions included updates to the LSTM operator and overall adjustments aimed at improving the representation and handling of types and shapes in ONNX models.
