Yutaro Yamada

I am a research scientist at Sakana AI. Previously I was a PhD student in Statistics and Data Science at Yale, and worked at Meta, Allen Institute for AI, and CyberAgent AI Lab as a research intern. My current interests include LLM agents, open-endedness, self-improving AI, and automated scientific discovery.
