Hi, I'm Yingjin JIANG (江英进) 👋

MPhil Student @ HKUST(GZ) | Researching LLM Agents & Reinforcement Learning

I am a research-oriented MPhil student passionate about building intelligent systems that can reason, learn, and act autonomously. My work lies at the intersection of Large Language Model (LLM) Agents and Reinforcement Learning (RL), driven by a systems engineering philosophy: I enjoy not only exploring novel AI concepts but also architecting robust, end-to-end solutions. My goal is to bridge the gap between theoretical research and practical, impactful applications.

🔭 I am actively seeking a Research Internship. I am eager to tackle challenging problems and contribute to a world-class team. I'm particularly interested in:

  • Autonomous Agent Architectures & Planning
  • Multi-Agent Systems & Collaboration
  • Human-AI Interaction & Tool Usage
  • Efficient Fine-tuning & RLHF for Agents
