About Me

I am a third-year Ph.D. student in Computer Science at the Australian Institute for Machine Learning (AIML), Adelaide University (formerly The University of Adelaide), advised by Prof. Javen Qinfeng Shi. Before my Ph.D., I received my M.Sc. and B.Eng. degrees from Wuhan University of Technology.

I study how language supervision shapes the semantics, geometry, and identifiability of multimodal representations. My long-term goal is to develop principled foundations for language-guided representation learning, with the aim of building multimodal systems that acquire structured, interpretable, and reliable representations of the world.

Research Interests

  • Representation learning: learning objectives and training paradigms; identifiability theory; semantic structure in learned representations.
  • Vision-language modeling: multimodal alignment; multimodal large language models; supervision design and data curation for multimodal learning.
  • Explainable machine learning: mechanistic interpretability; representation geometry; latent-structure characterization.
