• Education: PhD (Threat Assessment, 2004), MSc (Information Security, 2001), BSc (Computer Science, 2000)

His research focuses on proactive cyber defense mechanisms, including automated threat detection architectures (e.g., MIDAS), vulnerability exploitation modeling, and incentive-based security delegation. He has led projects like TAME (a threat assessment model for the METEORE system) and contributed to EU-funded initiatives like AI4CybSec. His work addresses IoT security, malware detection in smart environments, and trust frameworks for data sharing in MQTT environments.

Key projects include:

• TAME Phase 3 (2022-2023): Enhanced threat assessment models for real-time information environments
• AI4CybSec (2022): Integrating AI for automated threat analysis

He has published widely on digital forensics, cyber threat intelligence, and layered security systems, with over 39 peer-reviewed articles. His research emphasizes practical applications, such as mitigating wireless network attacks on smart homes and analyzing vulnerabilities in companion Android apps for IoT devices.
