About

I am a Postdoctoral Research Fellow at the National University of Singapore, working with Prof. Tat-Seng Chua. I received my Ph.D. from Hefei University of Technology in July 2025, under the supervision of Prof. Meng Wang. I also collaborate with Prof. Yunshan Ma at Singapore Management University. My research focuses on trustworthy AI and AI + X, with current interests in reliable and efficient large language models, recommender systems, and AI in finance. Outside of work, I enjoy jogging and hiking. A cold beer is my reward.
