Tsun-Yi Yang

I am founder and CEO of MIMI AI in London, working on GenAI systems for physical data, multimodal agents, and video world simulation.

Previously I was a senior research scientist at Meta Reality Labs, a senior LLM research engineer at Robin AI, and an applied scientist at Amazon. Before that I worked at Scape Technologies and Academia Sinica.

I received my Ph.D. in computer science from National Taiwan University. My research focuses on spatial intelligence, synthetic data generation, 3D scene understanding, image retrieval and matching, pose estimation, visual descriptors, and applied multimodal systems.
