Biography

Seungyul Han is an Associate Professor in the Artificial Intelligence Graduate School (AIGS) and the Department of Electrical Engineering (EE) at the Ulsan National Institute of Science and Technology (UNIST). He received his B.S. degree (double major in Mathematical Sciences) and M.S. degree in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea, in 2013 and 2016, respectively, and his Ph.D. degree in Electrical Engineering from KAIST. Prior to joining UNIST, he was a postdoctoral researcher at the Institute of Information Electronics at KAIST. He served as an assistant professor at UNIST until 2026 and is currently an associate professor at UNIST. His research focuses on reinforcement learning (RL) and LLM-based agentic AI, with an emphasis on learning, reasoning, and decision making for autonomous agents.

Recruitment

We are looking for motivated M.S. and Ph.D. students interested in Agentic AI (LLM/RL), and Physical AI. Interested applicants are encouraged to contact us (syhan@unist.ac.kr) with their CV, academic transcript, and a brief description of their research interests.

We are also recruiting postdoctoral researchers through the National Defense InnoCORE program (Annual Salary: KRW 90 million). We seek researchers interested in advancing research in these areas, with preference given to candidates who have published at top-tier AI/ML conferences. Interested applicants should contact us (syhan@unist.ac.kr) with their CV and representative publications.

Research Areas

Our laboratory conducts fundamental research in machine learning (ML) and reinforcement learning (RL), with a focus on building intelligent agents that can reason, learn, and make decisions through interaction. We study the integration of large language models (LLMs) and RL for agentic AI, develop RL methods for physical AI and embodied agents, and advance learning-based control and sequential decision making. We also explore real-world domains where these advances can enable intelligent and autonomous systems. Our research is organized into four main directions, as summarized in the figure below:
