👋 About Me

I am Yujing Wang (王誉静), an incoming PhD student (10.2026–) in the NLP Group, Department of Informatics, King’s College London, supervised by Prof. Hanqi Yan. I received my Master’s degree from the School of Artificial Intelligence, Beihang University, advised by Prof. Hainan Zhang. I received my Bachelor’s degree in the School of Mathematical Sciences, Beihang University (BUAA).

My research focuses on trustworthy large language models, with particular interests in reasoning, mechanistic interpretability, and chain-of-thought faithfulness.
