About me
Hi! I am Xun Liu, a first-year PhD student majoring in Computer Science at University of Illinois Urbana-Champaign, advised by Prof. Bo Li. Before that, I developed my interest in Computer Science and Computational thinking in Olympiad in Informatics (OI).
My current research interest lies in Trustworthy Machine Learning, especially in Large Language Models (LLMs) and LLM-based Agent Systems. Surrounding this topic, my research explores adversarial attack, red-teaming and alignment.
Whatever my future endeavors are, I shall steadfastly view the integration of technology and humanities as my life's mission. In a world increasingly dominated by digital advancements, I believe that preserving the essence of human culture and values is paramount. My journey will be dedicated to harmonizing the precision and innovation of technology with the depth and insight of the humanities. Of course, this vision presents a long road ahead, not just for me personally, but also for the academic and industrial worlds.
