Yongjie Wang王永杰

Biography

I am now a research staff at the Joint NTU-WeBank Research Centre at Nanyang Technological University, under the supervision of Dr. Shen Zhiqi. I received my Ph.D. in July 2023 at the College of Computing and Data Science (CCDS, NTU), under the supervision of Professor Miao Chunyan and Professor Wang Ke. Before that, I received a Bachelor's degree from the College of Software, Jilin University, and a Master's degree from the Institute of Computing Technology, Chinese Academy of Sciences, advised by Professor Zhang Yongdong and Associate Professor Gao Ke.

My research interests are centered on (1) developing trustworthy AI by integrating various explanation techniques to enhance model trustworthiness and robustness; (2) applying modern models (e.g., LLMs) to high-stakes applications.

I am open and welcome to collaborate with researchers with similar interests in XAI/LLM. Feel free to drop me an email.
