Han Luo portrait

I am a third-year undergraduate student in Computer Science at the University of Leeds, UK, and Southwest Jiaotong University, China. My research focuses on LLM agents.

I am fortunate to work with Prof. Lucy Lu Wang in the LARCH Lab at the University of Washington. Previously, I worked with Prof. Guy Laban in LabaLab at Ben-Gurion University of the Negev and at the University of Cambridge.

Open to collaborations: I am always interested in potential research collaborations. Please feel free to reach out via email!
