About

Research at the intersection of perception and intelligence.

I am a computer vision researcher focused on multimodal models and visual understanding. From July 2023 to June 2026, I worked as an Algorithm Expert at Ant Group. I received my Ph.D. in Computer Science from Wuhan University in 2023, where I worked on weakly supervised visual learning and remote sensing.

Experience

A path from visual learning research to multimodal AI.
