Ziyang Song Multimodal AI Researcher, Tencent

I am a researcher (Qingyun talent) at Tencent Video, working on multimodal video generation & world models for filmmaking.

I got my PhD degree (2021 ~ 2025) from The Hong Kong Polytechnic University, fortunately supervised by Prof. Bo Yang. My PhD research focused on 3D reconstruction and scene understanding. Prior to that, I got my M.Eng and B.Eng degrees (Honors Youth Program) from Xi'an Jiaotong University.

During my PhD study, I interned at TikTok (San Jose, CA) with Xinyu Gong. During my M.Eng study, I interned at SenseTime with Dongliang Wang, and Tencent Robotics X with Wanchao Chi.
