I am a final-year Ph.D. student in NLP and machine learning at Tohoku University, advised by Prof. Jun Suzuki, and a Google PhD Fellow. My research centers on the evaluation of large language models: how reliably we can measure their capabilities, how they generate and reason, and where they fail. This autumn I will join Prof. Mrinmaya Sachan’s group at ETH Zürich as a visiting researcher.

I pursue this across model families, from autoregressive to diffusion language models, as well as agentic systems, with publications at NeurIPS, ACL, and EMNLP. Most recently, I led Sumi, a fully open 7B uniform diffusion language model pretrained from scratch on 1.5T tokens.
