I am a second-year student within the Joint Ph.D Programme of Intelligent Institute of Machine at Hefei Institute of Physical Science,Chinese Academy of Science and University of Science and Technology of China advised by Prof. Yining Sun and Prof. Zenghui Ding. Previously, I received my Master degree in Data Science and Analytics at Hong Kong Polytechnic University.

My research interests center on trustworthy deployment with large foundation models (e.g. LLMs, LVLMs) from both a theoretical and empirical perspective. My recent work focus on efficient multimodal fusion in language models (e.g., images-text, videos-text) while improving their fairness, reducing hallucinations, and strengthening their reasoning capabilities.
