🤵🏻 About Me

I am a machine learning researcher with research interests in weakly supervised learning, robust machine learning, model adaptation. I obtained my Ph.D. degree from Department of Computer Science and Technology in Nanjing University in June 2022, where I was very fortunate to be advised by professor Yu-Feng Li (李宇峰). Currently, I am an Assistant Professor in School of Intelligence Science and Technology, Nanjing University (Suzhou Campus). I am also a member of LAMDA Group (机器学习与数据挖掘研究所), which is led by professor Zhi-Hua Zhou (周志华).

My research interests include topics in artificial intelligence and machine learning. Most recently, I am interested in the following topics:

  • Robust Machine Learning in Open Environments
    • Robust machine learning with new/unseen class or out-of-distribution (OOD) data.
    • Robust machine learning with decremental/incremental features.
    • Robust machine learning with changing data distributions.
  • Large Language Model and Foundation Models
    • Robustness and safety of large models.
    • Application of large models on specific downstream tasks.
  • Model Adaptation and Learnware
    • How to organize various machine learning models to solve different AI tasks.
  • Semi-Supervised Learning
    • Exploit unlabeled data to improve learning performance when labels are insufficient.
