I am a Technical Researcher at the Multilingual and Multicultural Communication Laboratory of the National Institute of Information and Communications Technology (NICT), Japan. I work under the supervision of Dr. Utiyama, Dr. Tanaka, and Dr. Tei.
I received my Ph.D. in 2026.06 from the Nara Institute of Science and Technology (NAIST), where I was advised by Prof. Taro Watanabe.
My research interests broadly lie in Natural Language Processing (NLP). I mainly focus on Machine Translation, with a particular emphasis on multilingual and multimodal settings.
You can learn more about my work through my Publications, Education, and Research Experience. You can also find me on DBLP, ACL Anthology, and OpenReview.
