Assistant Professor · Division of Computer Engineering, Hansung University
I am an Assistant Professor in the Division of Computer Engineering at Hansung University. My research focuses on personalized AI systems that understand individual needs from behavioral, contextual, and content signals. I develop recommender systems using user modeling, sequential learning, and graph-based methods, and combine language, images, reviews, metadata, and interaction histories through multimodal learning. I also study trustworthy review intelligence, including review helpfulness, information consistency, and deceptive-content detection.
I lead PRISM Lab, where we extend personalized AI from prediction and ranking to generation and intelligent interaction. Our current work adapts large language models and foundation models for generative recommendation, personalized content, and explainable decision support, while exploring retrieval-augmented generation, memory, and reasoning for conversational and agentic AI. Our goal is to build adaptive, reliable, and context-aware systems that help people discover, evaluate, and interact with information more effectively.
