Daisy Xinlei Lin

AI Researcher @ Amazon AGI SF Lab

I build AI agents that act like humans do, because the only thing more fun than being human is trying to recreate parts of it in silicon. I earned my PhD at NYU, where I studied planning and reinforcement learning: how minds and machines decide what to do next when the world is messy, uncertain, and adversarial. These days I work on LLM post-training, reasoning, and agents — systems that don't just talk, but act.
