Welcome to my academic homepage. I am a Ph.D. student in Computer Science at University of California, Los Angeles (UCLA) under the supervision of Song-Chun Zhu.

I work on representation learning for reasoning and skill learning tasks. In particular, I'm interested in building and understanding inductive biases for learning representations from multi-modal data, so as to systematically generalize in real-world physical and psychological dynamics. Some of my research keywords can be found below:

  • Humanlike Learning: Concept and language acqusition, Embodied agents, (Inverse) Reinforcement learning
  • Representation Learning: OOD generalization (domain and systematic), Energy-based generative model, Multi-modal learning
