Summary
🤩
Rockstar🎓
Top SchoolWenzhuo Liu is a Data Scientist with nine years of experience blending deep academic research and production-grade engineering to accelerate simulation and ML-driven systems. She holds a PhD in AI from Université Paris-Saclay and has cut simulation times by 99% on complex PDEs using hierarchical graph neural networks while improving OOD and small-data performance with meta- and transfer-learning techniques. Now at Stellia.ai, she applies that physics-informed ML expertise to real-world products and has a strong backend engineering pedigree—contributing Rust improvements to RisingWave and GPU/CUDA refinements to NVIDIA's CUTLASS. A seasoned educator and organizer, she taught deep learning to hundreds of students and ran academic workshops, and on GitHub she also optimized build and CI pipelines for large community projects like OI-wiki. Her background uniquely combines numerical PDEs, graph neural nets, and systems-level code optimization, enabling her to move ideas from research into high-performance production.
