Summary
👤
Senior🎓
Top SchoolOtto Lau is a Machine Learning Scientist with eight years of experience applying ML and statistics to frontier physics problems and commercial pricing systems. Currently finishing a PhD at Brown and working on a lepton universality test within CMS at CERN, he has built end-to-end solutions that extract extremely rare signals (roughly ten events from billions) using custom feature engineering, novel ML models, and rigorous statistical inference. He transitioned these research-grade skills into industry at Expedia, where he designed and productionized deep-learning elasticity and pricing models that materially impacted global booking metrics and automated ML pipelines. Comfortable leading projects from proposal to deployment, Otto blends experimental rigor with pragmatic engineering—scaling CI/CD, monitoring, and cross-functional collaboration across large teams. Equally at home in high-energy physics collaborations of thousands and product-focused ML teams, he brings a rare combination of domain-driven curiosity and measurable business impact.
