Recommendation systems, causal inference and experiment design.
David Lindelöf works across machine learning, causal inference, and large-scale experimentation. He brings practical experience in modelling, measurement, and production systems to his work at Gargantua, including the architecture of a recommendation engine.
His work at YouTube has focused on creator-facing systems, including defining metrics and designing and analysing experiments. Previously, he served as a director of data science at Expedia and as CTO of Neurobat, where he led research into adaptive heating controls tested in occupied buildings.
David’s background connects statistical methods with decisions about how systems perform in practice. That experience is relevant to Gargantua’s evaluation work: defining meaningful outcomes, designing informative tests, and interpreting results with appropriate attention to uncertainty.
