Biography

I am currently a third-year Ph.D. student at Beihang University, where I am privileged to be advised by Prof. Fuzhen Zhuang. I also maintain close research collaborations with Prof. Zhao Zhang and Prof. Shuang Li. Our team homepage is KTL.

My research interests focus on advancing the efficiency and reliability of machine learning models, specifically in Graph Learning, Recommendation, Trustworthy AI, and LLMs.
