Senior🎓
Top SchoolLingjun Chen is a Staff Data Scientist based in the San Francisco Bay Area with eight years of experience turning complex data into actionable product insights across recommendation, ads, and marketplace systems. At LinkedIn and Netflix she has driven large-scale work in topic modeling, LLM-powered evaluation, explainability for recommender systems, forecasting, and ads serving optimization, blending research-grade ML with production engineering. She holds an MS in Machine Learning and Data Science from Northwestern and began her career applying statistical methods in healthcare and high-traffic consumer products, giving her a strong foundation in both experimental design and system-level thinking. An active mentor and venture scout, Lingjun pairs technical depth with product intuition and a knack for translating model behavior into business-facing narratives. Notably, she has tackled cold-start and hybrid recommendation challenges early in her career, a thread that continues in her focus on explainability and scalable auto-evaluation for modern recommender and ad systems.
