Changhee Choi

Changhee Choi is an Associate Professor in the Department of Cyber Defense at Sejong University, South Korea, holding this position since 2025 after serving at the Agency for Defense Development (2013-2025). His research bridges cybersecurity and artificial intelligence with significant contributions to attack attribution and data augmentation.

His academic credentials include:

• Ph.D. from KAIST (2013)
• M.S. from KAIST (2010)
• B.S. from Yonsei National University (2008)

Research focuses on LLM-driven cyber defense systems, including attack campaign analysis using TTP synonym replacement and MITRE ATT&CK framework embedding. His work pioneers GAN-based data augmentation for packet/log generation and deep fake detection in digital forensics, with strong emphasis on automated cyber warfare simulation and AI-supported defense training.

Publications from 2019-2025 reveal consistent innovation in applying machine learning to cyber attribution challenges, particularly through vector space modeling of attack campaigns and generative techniques for security data synthesis. Recent work increasingly leverages large language models for threat intelligence processing.
