Ji Xie

I am an incoming PhD student at CMU LTI. I am currently a research intern at Bytedance Seed, advised by Xun Wang. Previously, I was a visiting student at the Berkeley AI Research (BAIR) Lab, UC Berkeley, advised by Prof. XuDong Wang and Prof. Trevor Darrell.

My interests span from applications to fundamental principles. My current research focuses on foundation multimodal models and their applications.
