Welcome to my GitHub profile! I am a Junior Computer Science student at Sun Yat-sen University (SYSU) and a Research Intern at Microsoft Research Asia (MSRA).

My long-term goal is to build a unified world model that seamlessly integrates understanding and generation across modalities and agents.

📢 I am seeking PhD opportunities for Fall 2027. If you are interested, please contact me directly!

• Education: B.Eng. in Computer Science, Sun Yat-sen University (Sept 2023 - Present).
• Research Labs:
  • Microsoft Research Asia (MSRA), Shanghai ML Group.
  • HCP Lab, Sun Yat-sen University.
• Role: Reviewer for CVPR 2026, AAAI 2026, ICLR 2026.
• Interests beyond tech: Philosophy (Kant, Nietzsche), Literature (Tolstoy, Kafka), and the intersection of humanity and technology. 📚🤔

My research centers on advancing multi-agent collaborative intelligence by integrating Visual Language Models (VLMs) and Large Language Models (LLMs) with Reinforcement Learning (RL).

• Multi-Agent Systems: Knowledge-aware coordination, Bayesian bandits, Game-theoretic uncertainty trading.
• Policy Optimization: PPO, MAB, GRPO, and MAPPO-like RL frameworks.
• Generative Models: Video generation (Hierarchical VAE), 3D generation, and Unified World Models.
• VLM Architectures: Discretized representations (VQ), Post-training with RFT (LLaVA).
