Andrea Mock

I'm a data scientist and ML researcher with 4+ years of industry experience (Aura, DraftKings), working on behavioral modeling, recommendation systems, and ML infrastructure. I now study how people interact with technology, and what those interactions can tell us about wellbeing, behavior, and AI safety.

Currently a graduate researcher in Stanford's Autonomous Agents Lab with Nick Haber, and an Accel Leaders Program Fellow.
