I am an undergraduate student majoring in Artificial Intelligence at the School of Intelligence Science and Technology, Nanjing University (NJU).
My research interests lie in AI agents, large language models, multimodal representation learning, and reliable evaluation. I am particularly interested in building agentic systems that can perceive, reason, and generalize in open and changing environments.
At NJU, I am advised by Prof. Lanzhe Guo in the LAMDA Lab and Prof. Kai Zhang in the CVL Lab. I also work with Prof. Tao Yu in the XLang Lab at The University of Hong Kong on OSWorld 2.0, a benchmark for evaluating long horizon computer use agents.
