Bio
I am currently an algorithm researcher working on multimodal AI.
I received my Ph.D. degree from ShanghaiTech University in 2026, where I was advised
by Prof. Sibei Yang.
Previously, I obtained my Bachelor's degree from Southwest University in 2021.
My research interests span computer vision, natural language processing, and their intersection, with a focus on
Vision-Language Understanding and Large Vision-Language Models.
