  • Biography

    I am an Associate Researcher at the School of Software Engineering/Suzhou Institute for Advanced Research, University of Science and Technology of China (USTC), and a member of the USTC-DILab. I received my Ph.D. in the School of Data Science, University of Science and Technology of China (USTC), supervised by Prof. Qi Liu and Prof. Yang Wang. Before starting my Ph.D. study, I received my Bachelor's degree from Jilin University (JLU) in 2017. I have published about 30 high-level papers on research journals and conferences, including some top level international journals and conferences, such as ICLR, KDD, AAAI, WWW, ICDM, and some IEEE Transactions, such as IEEE TKDE, IEEE TITS, and IEEE TVT. I am broadly interested in imbalanced/long-tailed learning, interpretable data augmentation, multi-objective optimization, open environment data mining, and generalized AI for science.
