Iβm currently an assistant professor in the School of Computer Science and Engineering at Beihang University (BUAA). Before that, I received my Ph.D. degree from Beihang University, under the supervision of Prof. Jianxin Li. Further before, I obtained the B.S. degree from Xidian University. My research interests include Data Mining, Deep Graph Learning and Trustworthy AI. Please feel free to send me an email if interested to discuss or work together. |
