🤵🏻 About Me

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 associate professor Yang Wang (汪炀) and professor Qi Liu (刘淇). Before starting my Ph.D. study, I received my Bachelor's degree from Jilin University (JLU) in 2017. I have published more than 30 high-level papers on research journals and conferences, including some top level international journals and conferences, such as ICML, NeurIPS, ICLR, and IEEE TKDE. I am broadly interested in open environment data mining and generalized AI for science.

Most recently, I am interested in the following topics:

Open Environment Data Mining and Model Generalization

Non-ideal Data Distribution: Imbalanced/Long-tailed Learning and Out-of-Distribution (OOD) Generalization
Dynamic Data Distribution: Continual Learning
Sparse Data Distribution: Interpretable Data Augmentation
Variable Learning Objective: Multi-objective Optimization

Generalized AI for Science

LLM for Science: LLM-driven Scientific Data Mining (e.g., Property Prediction, Structure Prediction, Material Discovery)
AI for Chemistry: Spectrum-Structure-Property Relationship Learning (e.g., PXRD, NMR)
AI for EDA: Intelligent Electronic Design Automation
AI for City and Transportation: Spatiotemporal Data Mining

📢: 招收对深度学习、AI4Science感兴趣且有较好数理基础的学生 [推免/工程实践/远程科研实习]，可通过邮箱联系我，请附上个人简历。

📢: 中国科学技术大学数据智能实验室(DILab)诚招特任副研究员及博士后! 研究方向包括时空数据挖掘、开放机器学习与模型泛化、AI for Science。如您对团队研究方向感兴趣，欢迎您直接与团队负责人汪炀老师联系!
