Chihiro Nakatani

Ph.D student at Toyota Technological Institute, advised by Prof. Norimichi Ukita at IIM Lab. My research focuses on understanding collective human behavior from video — with applications in sports AI and embodied agents. I have published first-author papers at CVPR and ICCV. Beyond my home lab, I have been a visiting researcher at Idiap Research Institute (Switzerland) with Prof. Jean-Marc Odobez (Idia/EPFL), and a full-time analyst intern at the Hokkaido Nippon-Ham Fighters baseball team.
