Summary
👤
Senior🎓
Top SchoolYaohui Zeng is a Senior Data Scientist in Mountain View with 11 years of experience applying high-dimensional statistical learning, sparse models, and scalable computing to real-world problems across autonomous driving, biostatistics, and operations research. At Waymo and Google he translated complex data and probabilistic models into production-ready analytics for safety and reliability, building on a PhD in Biostatistics and deep expertise in Bayesian inference, PK/PD modeling, and mixed-effects models. He has a track record of engineering efficient tools—authoring R packages like biglasso for out-of-core lasso fitting and grpregOverlap—and has demonstrated the ability to analyze 30+ GB genomic datasets on modest hardware. His background spans programmatic breadth (R, RStan, Python, C/C++, SAS, Java) and practical optimization techniques that produced measurable energy and cost savings in prior academic projects. Yaohui combines rigorous methodological research with hands-on software development and large-scale simulation design, uniquely positioning him to bridge statistical theory and production data systems. Outside core roles, he’s contributed open-source tools and reproducible Bayesian workflows that streamline model-driven decision making.
