About Me

Hello. I’m Charmgil Hong.

I am an associate professor in the School of Artificial Intelligence, Computer and Electrical Engineering at Handong Global University, Korea. My research interests focus on developing and applying machine learning and data mining techniques to solve large and complex data-driven problems. Before joining Handong, I had the privilege of studying under the guidance of Dr. Milos Hauskrecht and earning my PhD from the University of Pittsburgh.

• Research group: Handong Artificial Intelligence Lab. (HAIL)

Teaching

• ITP40010 Machine Learning
• ECE30030/ITP30010 Database System
• ECE30008 Intro to Artificial Intelligence
• ECE20010/ITP20001 Data Structures
• ITP20004 Open-source Software Labs
• ECE10020 Intro to Engineering Design
• ECE10003 C Programming Labs
• ECE10002 C Programming

Research Interest

My research focuses on machine learning for heterogeneous and multimodal real-world data, with an emphasis on reliable and interpretable modeling. I am particularly interested in biomedical and industrial applications, including clinical prediction, drug safety, and forecasting for markets, prices, demand, and inventory. More recently, I have also been exploring large language models and AI agents as part of this broader research direction.

I am also interested in AI/ICT for Korean unification studies and data-driven capacity building in developing countries.
