I am a Research Specialist at NTT Human Informatics Laboratories. My research interests are not limited to speech-related technology such as speech recognition, speech separation, and speaker diarization, but also include image processing and multimodal processing.

Prior to joining NTT, I was a Senior Researcher at Hitachi, Ltd. Research and Development Group from 2017 to 2024.

I received my Ph.D. degree in 2023 from University of Tsukuba under the supervision of Prof. Takeshi Yamada. At University of Tsukuba, I was a member of the Multimedia Laboratory.

Before that, I studied computer vision at the Aizawa-Yamasaki Laboratory (now Aizawa-Yamakata-Matsui Laboratory) of the University of Tokyo, where I received B.E. and M.E. degrees under the supervision of Prof. Kiyoharu Aizawa.
