Senior🎓
Top SchoolJeffrey Wong is a Senior Staff Mathematical Engineer in San Francisco with 13 years of experience building high-performance statistical software and decision-making systems for companies like Airbnb, Apple, and Netflix. He specializes in computational causal inference, adaptive experimentation, and optimal policy algorithms, and has led efforts that made complex causal models 50–150x faster and reduced data volumes by 100x to enable production-grade experimentation platforms. A horizontal leader and hands-on builder, he blends deep statistical research with systems engineering to democratize advanced analytics across product and operations teams. Jeffrey’s work spans multitouch attribution, bandit-based best-arm identification, and quantile/time-varying treatment effects, reflecting a rare combination of game-theory-informed modeling and production engineering. He holds MS and BS degrees from Stanford and often advises startups and speaks on incrementality and rigorous measurement in programmatic advertising.
