About Me

I am a researcher at the UI-Venus Team, Ant Group. I received my Ph.D. in Computer Science from Shanghai Jiao Tong University in 2022, advised by Professor Liqing Zhang. Prior to that, I obtained my B.Sc. in Mathematics from SJTU in 2016.

My research benefits from collaboration with esteemed colleagues including Mr. Haoxing Chen, and Mr. Zhuoer Xu.

Research Interest

My current focus is GUI/CLI agents and multimodal LLaDA models:

GUI/CLI Agents

Building agents for mobile-use and computer-use scenarios, covering GUI grounding, navigation, and automation with multimodal large models.

Multimodal LLaDA

Studying multimodal LLaDA models and their applications in agent and vision-language tasks.
