I'm a Computer Vision Research Scientist at Woven by Toyota and a Cooperative Research Fellow at Y. Sato Lab, the University of Tokyo. I focus on computer vision and human activity understanding, specifically involving vision-language multimodal reasoning, video and multi-view understanding, and human body perception.
