I am a third-year Ph.D. student at Nara Institute of Science and Technology (NAIST), supervised by Prof. Taro Watanabe.
The expected graduation date is June 2026.
I am also working for National Institute of Information and Communications Technology (NICT), Japan, as a Technical Researcher in the ATT Lab of ASTREC, where I work under the guidance of Dr. Utiyama, Dr. Tanaka, and Dr. Ding.
I maintain a broad interest in Natural Language Processing (NLP) in general.
My main research focuses on Machine Translation, particularly in Multilingual settings.
You can learn more about me through my Publications, Educations and Research Experiences. You also can find my DBLP, ACL Profile and OpenReview Profile.
