Research Interest
My research focuses on understanding cybersecurity by integrating human and organizational behavior through simulation. Using agent-based modeling, I study how people in real organizations follow security policies and respond to cyber threats such as phishing and denial of service attacks. I explore how human factors such as fatigue, perception, and performance shape these responses, and I extend the evaluation of intrusion detection systems beyond simple accuracy to include their resilience in real attack scenarios. I also model attacker personalities and strategies to create more realistic threat simulations and to develop effective defense approaches. Ultimately, my work aims to design security strategies that consider technology, humans, and organizations together, contributing to a safer and more resilient digital society.
