Bio

I'm a Graduate Student at Hanbat National University, advised by Prof. Yunho Jeon. My research interests center on efficiency and personalization in AI systems, with a particular focus on computer-use and multimodal agents that can adapt to individual users.

I'm interested in developing agents that enable users to interact with digital environments through natural language, carrying out real-world tasks in ways that are both practical and personalized.
