3rd year Phd candidate at AIML

About Me

I am actively looking for industry positions in MLLM pretraining, VLA, World Model, and related areas. Feel free to reach out via email if you are interested!

Hi 👋, I am a final-year Ph.D. candidate at the University of Adelaide, supervised by A/Prof. Bohan Zhuang and A/Prof. Qi Wu.

My research focuses on developing efficient and scalable AI algorithms for multimodal understanding and image generation. Previously, I have worked on the following topics:

  • Long Context Prefilling Efficiency of MLLMs covering inference, pretraining, and post-training, including ZipVL, OmniSparse, and Sparsity Forcing.

  • Long Context Decoding Efficiency of Image Generation with speculative decoding, parallel pretraining and post-training distillation, including ZipAR, NAR and FlashAR.

Currently, my research focuses on embodied learning, with two main directions:

  • Long-horizon Decision Efficiency of VLA/WAM/Agent: improving policy efficiency and computation efficiency of VLA/WAM/Agent models to complete tasks with fewer action steps and over longer horizons, reducing redundant inference cost while maintaining robust task performance.

  • World State in World Models: studying world models through a progressive pipeline from physical video generation and physical system modeling to world state evolution and next-state prediction, aiming to model physical and causal world states for more faithful world simulation.

We are looking for highly self-motivated Master, PhD students and interns. If you are interested in joining our ZipLab team, please feel free to contact us with your CV as the post!
