Summary
👤
Senior🎓
Top SchoolKai Liu is an Applied Scientist with a PhD in Computational Biology and over a decade of experience applying ML to real-world problems, currently driving personalization and recommender systems at Zillow. He has led modeling efforts that contributed to over $11M in revenue and more than half of his org’s annual goals, shipping multiple winning A/B tests and the first finance feature for Zillow’s Home Loan business. His work spans end-to-end system design—from real-time ranking APIs and latency tuning to building evaluation frameworks, including a novel 2-D relevance metric that sped team science velocity by enabling no-code model evaluation. Earlier research in infectious disease surveillance produced high-accuracy supervised anomaly detection and an automated data pipeline ingesting hundreds of disease-related signals, reflecting his strength in combining statistical rigor with production engineering. He has published in computational linguistics and filed a patent on personalized feeds, blending academic depth with product impact. Based in Seattle, Kai pairs a strong research pedigree with hands-on delivery in large-scale ML systems.
