Ji Xie

I am a senior undergraduate student at Zhejiang University, pursuing a Bachelor of Engineering in Computer Science and Technology with Honors from Chu Kochen Honors College. I expect to graduate in June 2026. Rank: 2/147. GPA: 93.8/100.

Currently, I am a research intern at the Berkeley AI Research (BAIR) Lab, UC Berkeley, advised by Prof. XuDong Wang and Prof. Trevor Darrell.

My long-term goal is to build a unified, controllable, and powerful multimodal model and apply its strong generative priors to the construction of world models and embodied AI.
