Biography

I am currently a Project Specific Assistant Professor at NII Research and Development Center for Large Language Models (国立情報学研究所大規模言語モデル研究開発センター). My current research focuses on multilingualism, multimodality, and model reasoning, especially on how to evaluate, interpret, and improve large language models, as well as downstream applications toward computational social science.

I obtained my PhD from Kyoto University, majoring in Intelligence Science and Technology, under the supervision of Sadao Kurohashi at the Kurohashi-Chu-Murawaki Lab. I received my bachelor’s degree in Information and Computing Science from the School of Mathematical Sciences at Peking University, together with a second bachelor’s degree in Computer Science from the School of Electronics Engineering and Computer Science. During my master’s studies, I was supervised by Daisuke Kawahara. I have also conducted research internships at RIKEN and NICT.

Research Interests:

• Multilingual Large Language Models, including cross-lingual transfer, multilingual representations, and cultural and linguistic biases.
• Interpretability and Evaluation of Large Language Models, focusing on understanding the multilingual and reasoning abilities of language models.
• Training and Post-training of Large Language Models, including multilingual pretraining, efficient adaptation, and reinforcement learning.
• Multimodal Large Language Models, particularly how language models integrate and reason over information across modalities.
• Computational Social Science, focusing on agentic applications of large language models in social science domains.
