About Me
Who I Am
I'm Chengyu, currently pursuing my Master's in Artificial Intelligence at Northeastern University. I'm passionate about building AI systems that create meaningful impact in the real world.
My research focuses on LLM deployment, RAG systems, GUI agent safety, and cross-cultural AI alignment. I'm particularly interested in how AI systems can be adapted to different cultural contexts.
