Biography

I obtained a Diploma in Electrical Engineering from Democritus University of Thrace in Greece, an MBA from Keele University in the UK and a PhD in Computer Science (network security and cryptography) from Aston University. I am a certified Computer Hacking Forensic Investigator (CHFI). I have worked in the Industry as Information Security Consultant and served as an expert witness in Information Security in the UK and Greece. My research falls in the area of digital forensics and incident response, with the recent years focusing on digital forensics for investigating Intellectual Property infringements, following the close collaboration with the EU Intellectual Property Office (EUIPO) and UN's Interregional Crime and Justice Research Institute, UNICRI. I have participated in a number of EU and nationally funded research projects and in several national and international cyberdefence exercises. I have over 160 publications in journals, book chapters and conference proceedings and serve as a referee on several reputable conferences and journals (for example, IEEE Communications Letters, Computers & Security)...
