My name is Constantinos Patsakis and currently I'm assistant professor at the Department of Informatics, University of Piraeus and adjunct researcher at the Institute for the Management of Information Systems (IMIS) of Athena Research and Innovation Centre.
My first degree is in Mathematics from the University of Athens, Greece and then I continued with a M.Sc. in Information Security from Royal Holloway, University of London. I obtained my PhD in Security from the Department of Informatics of University of Piraeus. My main areas of research include cryptography, security, privacy and data anonymization.
In the past I worked as Researcher at the UNESCO Chair in Data Privacy at the Rovira i Virgili University (URV) of Tarragona, Catalonia, Spain and as a Research Fellow at Trinity College, Dublin Ireland.

In this academic year I will be teaching the following courses:


  • Information & Code theory
  • Management of Security Systems
  • Introduction to Computer Science
  • Computational Number Theory


  • Digital Forensics & Malware Analysis
  • Cryptographic protocols
  • Cryptography
  • Introduction to Computer Science

For more info about the courses, students may refer to our GUNet. Dissertation topics can be found here.
