Haiyang Liu

I'm a researcher working on multimodal AI models for video, 3D animation, and robotics. My work primarily focuses on generating human videos/3D animation from multimodal conditions such as text, audio, and image.

At Hedra, I led research on the real-time talking heads model Livatar-1 and the multimodal video generation model Omnia. I worked hands-on across the data, model architecture, and training infrastructure.

Before that, I completed my Ph.D. at The University of Tokyo, with internships at Hedra Research, Adobe Research, CyberAgent AI Lab, and Huawei Research Tokyo. I advised 3D animation research in Alaya Lab.
