Zhejiang University · Hangzhou, China

Hi! I am Ji Ma (马骥). I am a CS Ph.D. candidate at the State Key Lab of CAD&CG, Zhejiang University, supervised by Prof. Yingcai Wu and Prof. Jiachen Wang. My research interests lie in AI4Sports and Human-Centric AI. I focus on incorporating professional domain knowledge into data-driven models to democratize elite sports expertise. Specifically, I utilized multimodal sensing, embodied AI and LLMs to enable intelligent coaching and automated tactical analysis in table tennis.

I served as the chief architect of the CTTT’s Intelligent Big Data Platform and International Tournament Management System, aiding the national team in preparing for major international competitions.

I love running. I led the effort to establish the Kuafu Running Club as a registered student organization at Zhejiang University and served as its inaugural president. We maintain a community of more than 2,300 student runners.
