Biography

I study how AI systems represent and use information, with a particular focus on language models. My research asks how they encode numbers, keep track of entities, and store facts about the world. As these systems become more complex, I also investigate how AI can help us understand their internal workings.

At RIKEN AIP, I’m Deputy Team Director of the Natural Language Understanding Team, and I also hold an appointment as Specially Appointed Associate Professor at Tohoku University’s Center for Language AI Research. I received my PhD in computational linguistics from Heidelberg University.
