2nd-year Ph.D. student at the University of Tokyo

I am currently a 2nd-year Ph.D. student at MIL, the University of Tokyo, advised by Prof. Tatsuya Harada and Lect. Yusuke Mukuta. I also received B.S. and M.S. from The University of Tokyo, advised by Prof. Tatsuya Harada and Lect. Yusuke Mukuta.

Research Interests

My research focuses on modeling human dynamics and 3D environments from multimodal data. I am particularly interested in human motion generation and prediction, feed-forward 3D/4D reconstruction, and time-series forecasting. Recently, I have been exploring the use of multimodal large language models to better understand complex human behaviors and dynamic scenes. In the long term, my goal is to build human-centered intelligent systems that can anticipate human intentions and motions, enabling robust and adaptive human–robot interaction in real-world environments.
