About Me

I am an undergraduate student at The Hong Kong University of Science and Technology, Class of 2027. I am fortunate to be advised by Prof. Yi R. Fung, and mentored by her PhD student Xinyu Geng, working on problems at the intersection of large language model agents, tool use, and evaluation.
