Ryuhei Miyazato

I am currently a researcher at the Japan AI Safety Institute and the University of Electro-Communications under Satoshi Hara. I received my Master’s degree from the same university under the supervision of Kei Harada.
My research interests lie in evaluation and alignment for trustworthy AI and AI Safety. At Japan AISI, I evaluate Japanese LLMs, with a particular focus on robustness to misinformation and disinformation, as well as hallucination generation. At UEC, I work on robust hallucination detection using model-internal representations, with the goal of improving methods for detecting model misalignment.
