I work on AI Alignment & Safety at Sony Computer Science Laboratories (Sony CSL), focusing on Model Psychology, Artificial Metacognition (especially in large language models), and Consciousness Science. My work includes studies on LLMs' metacognition (Yoshizawa et al., 2026) and the relationship between Metacognitive Closure and consciousness in LLMs (Yoshizawa & Mogi, 2026).
I also lead the Metacognition & Hallucination Team at Shiba AI, a Tokyo-based organization working on AI safety, alignment, and governance.
Alongside my AI research, I am an undergraduate physics student at Tokai University, where I conduct research in Quantum Thermodynamics under the supervision of Dr. Eiki Iyoda.
I serve as an Expert Consultant in AI evaluation and safety at Duco, a company based in San Francisco, USA.
