Yichen Xie (谢熠辰)

Research Scientist at Luma AI

Hi, there! I am Research Scientist at Luma AI working on video foundation models. Before this, I received my Ph.D. degree from UC Berkeley in 2026 under the supervision of Prof. Masayoshi Tomizuka in the Mechanical Systems Control (MSC) Lab, which is affiliated with the Berkeley Artificial Intelligence Research (BAIR). During my graduate study, I am fortunate to have the opportunity as an intern at Apple, Waymo, Applied Intuition and Cruise.

Prior to this, I obtained my B.E. degree (Sep. 2017 – Jun. 2021) in Computer Science and Engineering from Shanghai Jiao Tong University with an honor degree at Zhiyuan Honors Program, where I was advised by Prof. Cewu Lu and Prof. Quanshi Zhang.

My primary research interests focus on multimodal foundation models and 3D computer vision, especially their intersection and their applications to embodied agents.

I am open to collaboration and chat — please feel free to reach out if interested!
