AI Engineer and Researcher. I'm a Computer Science student at Kyungpook National University working on reliable, evidence-grounded LLM systems. My research looks at how language models use the evidence they're given, in multi-document question answering, retrieval- and search-augmented reasoning, and tool-using agents. I also build software: Mahallify, a location-based community platform I founded, and ADVS, an OCR system that verifies Korean administrative documents.
