I am an Information Security professional, specialized in Cryptography, and my career is focused on research and education. Since March 2023, I function as an Assistant Professor at the Leiden Institute of Advanced Computer Science (LIACS), Leiden University. My research interests lie mainly in the field of Applied Cryptography, and Privacy Enhancing Technologies. Specifically, I am interested in technologies and applications of Computing on Encrypted Data (e.g., homomorphic encryption, and multiparty computation).
Formerly (2014-2023), I worked as a Senior Lecturer/Researcher at Saxion University of Applied Sciences, the Netherlands, where I was affiliated with the Bachelor programme Security Management, and the research group Social Safety & Security -lectoraat Maatschappelijke Veiligheid-. As a Saxion lecturer, I integrated theory and practice to disseminate the information security specialist's key professional aspirations.
In the past, I have also functioned as a junior researcher in the faculty of Electrical Engineering, Mathematics and Computer Science at the University of Twente (2012-2014), where I conducted research in the area of Privacy-Preserving Data Mining in Electronic Health Records.
I obtained my Ph.D. degree in Engineering Science, Electrical Engineering, from COSIC, KU Leuven (2021), with the Thesis entitled "Secure and Efficient Computing on Private Data", under the supervision of Dr. Frederik Vercauteren, and Dr. Bart Preneel. I obtained my M.Sc. in Information & Communication Systems Security from the University of the Aegean, School of Engineering (2011). I completed my Master's Thesis, entitled "Constant Round Group Key Agreement Protocols: A Comparative Study", under the supervision of Dr. Elisavet Konstantinou. I received my B.Sc. in Informatics from the Technological Educational Institute of Athens, School of Technological Applications (2009), with the Thesis entitled "Implementation of an Intrusion Detection Mechanism Specialized on Insider Attacks" (supervision Dr. Ioanna Kantzavelou).
