Summary
👤
Senior🎓
Top SchoolGreg Faletto is a data scientist and PhD-trained statistician who builds rigorous, production-ready causal inference and machine learning solutions to measure product and advertising impact. With nine years of experience spanning Google, VideoAmp, ZipRecruiter, and Live Nation, he translates messy real-world data into actionable metrics and scalable methodologies—from A/B testing improvements at Google to lift estimation for TV and streaming ad campaigns. His academic work (ICML, PNAS) produced open-source tools for rare-event probability estimation and clustered feature selection, and he has a track record of turning novel research into deployable code. Based in San Francisco, he combines deep probabilistic thinking with practical engineering (Python, R, SQL, Spark) and a knack for communicating complex results to product and business stakeholders. An unexpected strength is his live-event audio engineering background, which honed his calm problem-solving under tight real-world constraints.
