Sungho Park

I am a Ph.D. student in the Data Systems Lab at POSTECH, advised by Prof. Wook-Shin Han. My research centers on developing self-improving AI agents, inspired by Sun Tzu’s The Art of War: "If you know the enemy and know yourself, you need not fear the result of a hundred battles." I view the path to Artificial General Intelligence (AGI) as rooted in a model's ability to autonomously identify its weaknesses—"knowing oneself"—and iteratively enhance its performance.

As a primary testbed for this self-improving framework, I am currently focusing on the development of Agentic RAG systems for deep reasoning across large-scale multi-modal data, such as complex tables and unstructured text. This work connects multi-hop retrieval with broad information synthesis, empowering agents to traverse intricate data environments with exceptional accuracy.
