Hi there! I am an associate professor at School of Artificial Intelligence and Data Science, University of International Business and Economics. I received Ph.D. in Computer Science from Renmin University of China in 2023 advised by Prof. Ji-Rong Wen and Prof. Jun Xu. Before that, I got the M.S. degree in Software Engineering from University of Science and Technology of China in 2018 and B.S. degree in Computer Science from Liaoning University in 2014.
My research interests lie at Information Retrieval, Large Language Models, and Legal Intelligence. I am actively seeking self-motivated students for M.S. and intern positions. If you’re interested, please email me with your CV, thanks!
