Ph.D. Candidate in Cybersecurity (Expected Aug 2026)
Korea University · Seoul & Abu Dhabi
Designing domain-specific generative models (DiT, GAN) to address data insufficiency issues in cybersecurity, while investigating vulnerabilities in LLMs & agentic AI.
I am an AI & Security Researcher at Korea University. My approach to security research is built on five years of experience at the Agency for Defense Development (ADD), as well as international joint projects with the UAE Ministry of Defense.
As a Ph.D. candidate in Cybersecurity at Korea University, I have mainly explored how generative models can improve cybersecurity, designing diffusion transformers (DiT) and GANs to address data insufficiency in physical and wireless security, including RF signal processing and side-channel analysis. I have also advanced cyber threat intelligence (CTI) using NLP and LLMs to analyze attack campaigns.
My work now moves toward AI safety and resilience, focusing on adversarial robustness in LLMs and trustworthy deployment of agentic AI in security-critical settings.
Our paper on hardware wallet side-channel attacks has been accepted to ACM CCS 2026.
Our paper on multicore side-channel monitoring has been accepted to ACM/IEEE DAC 2026.
I was awarded the Korea University Graduate School Achievement Award.
Our paper on DiT-based EM trace augmentation has been accepted to IEEE Computer Architecture Letters.
Our paper on LLM-based TTP extraction has been accepted to IEEE Access.
Our paper on DDoS detection has been published in JICS.
Our paper on DiT-based drone signal augmentation has been accepted to IEEE Signal Processing Letters.
Our paper on cyber campaign augmentation for group attribution has been accepted to IEEE Transactions on Information Forensics and Security (TIFS).
I was awarded commendations from the UAE Ministry of Defense and the UAE Ambassador.
Our paper on web shell detection has been published in JKIISC.
Our paper on GAN-based I/Q data augmentation has been published in IEEE Transactions on Dependable and Secure Computing (TDSC).
