Yixuan Ren

I am a Research Scientist at Luma AI, working on multimodal foundation training for robotics and media creation. I also work on coding/agentic policy for robot manipulation.

I obtained my Ph.D. in Computer Science at the University of Maryland, College Park, advised by Prof. Abhinav Shrivastava. I also received my M.S. degree here. Prior to that, I received my B.E. degree from Tsinghua University.

I was fortunate to have the opportunity to collaborate with and learn from many talented researchers and mentors through internships:
