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 Sports Data Mining 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 love running. I am a core committee member and a pacer for the Kuafu Running Club at Zhejiang University, a community of more than 1,600 student runners.

Running is like the flow of water, quiet but powerful. — Kipchoge
