Senior🎓
Top SchoolYuqian Liu is a Principal Data Scientist in New York with 11 years of experience applying a rare blend of physics, statistics, and software engineering to production ML systems. At Capital One she manages multiple end-to-end models spanning customer acquisition, eligibility, risk, and fraud, and has designed foundational A/B testing and model governance practices. Her background includes a PhD in Astrophysics from NYU, where she translated complex astronomical data analysis into rigorous statistical workflows—skills she now leverages to operationalize models at scale. Known for partnering closely with product, engineering, and analytics teams, she combines domain rigor with pragmatic automation, having built reproducible Python model pipelines and dashboarded results in Tableau. An uncommon strength is her ability to move projects from research questions to audited, production-ready solutions while maintaining scientific skepticism and clear interpretability.
