I am a PhD student in the Information Security Group at the University College London, under the supervision of Professor George Danezis.

My research interests include Private Computations, Privacy-preserving Statistics & Analytics, Anonymity networks and certain aspects of Systems & Telecommunication Networks Security . I am always keen to do practically applicable research, and hence I enjoy building actual systems, which solve real-world problems.

I hold an M.Sc. in Information Security from UCL, and a B.Sc in Computer Science from University of Macedonia, Greece. Moreover, I participated in a summer student exchange program on "Security in IT Systems", in Danmarks Tekniske Universitet.

In the past, I worked as a researcher in the Computer Security Group of University of California, Santa Barbara, in the Centre for Research & Technology Hellas (CERTH) and in the GT Security/Security Information Solutions department of Deutsche Bank, in Frankfurt.
