I am Fan LIU, a research student at HKUST(GZ). My current interest is in trustworthy LLM, LLM for Reasoning and LLM-Powered Agents, etc. My research papers have been published in NeurIPS/KDD/ICMLW/TFS, etc. For more details, please refer to [Google Scholar]

Currently, I am particularly interested in building trustworthy and effective LLMs, which I approach through three key aspects: evaluation, foundational capabilities, and real-world applications.

1. LLM Evaluation: Understanding the boundaries of LLMs, including their trustworthiness and reasoning capabilities. This involves assessing robustness, reliability, and alignment with human values.

1. Enhancing Fundamental Capabilities: Based on evaluation insights, I explore methods to improve LLM trustworthiness and reasoning, including defending against jailbreak attacks, ensuring alignment with human values, and addressing fundamental challenges in logical reasoning and reflection.

1. LLM-Powered Agents and Applications: Leveraging improved foundational capabilities to develop trustworthy, real-world AI agents. This involves studying agent alignment, decision-making, and adaptive interactions in dynamic environments.

Related paper: [Jailbreak Judge Agent], [Travel Planing Agent]

Through this structured approach, my research aims to bridge the gap between LLM evaluation, theoretical advancements, and practical deployment, ultimately contributing to the development of more reliable and capable AI systems.

If you are interested in my research, feel free to reach out for discussions, collaborations, internship opportunities, or any related inquiries.
