About me

Hi, I'm Zeyang! I'm currently a fourth-year Ph.D candidate in the Department of Computer Science & Technology at Tsinghua Univeristy, advised by Prof. Wenwu Zhu and Prof. Xin Wang. I got my Bachelor degree in Department of Computer Science and Technology at Tsinghua University in 2020. I also got my Second Degree in School of Economics and Management at Tsinghua University in 2020.

Research interests

My research interests lie in Open-environment Graph Machine Learning, including the subtopics:
  • Automated Architecture Adaptation: adapt to new environments, datasets, tasks by automatically designing, searching, modifying the neural network architectures
  • Out-of-distribution Generalization: generalize the neural network models under distribution shifts by discovering and exploiting the invariant patterns across environments
  • Large Language Models: enhance the zero/few-shot learning and reasoning abilities of the models in open environments by leveraging LLMs' strong abilities (textual understanding/planning/etc.)
  • Ai4Science Applications: solve the scientific problems by leveraging the AI techniques, including mathematical problems, drug discoveries, medical care, etc.
