Overview

My research interests span privacy, security, and (computational) trust in mobile networks.

Privacy is my main current focus, and these are the questions I try to answer:

  • In what ways do we disclose private information (through smartphone apps, social networks, Internet-enabled devices)?
  • How can we protect our information without going off the grid (by adding some sort of noise)?
  • Most importantly, how can we reason concretely and quantitatively about privacy attacks and defences (e.g. in order to provide privacy guarantees, or to monetize private information appropriately)?

Biography

George Theodorakopoulos received the Diploma degree from the National Technical University of Athens, Greece, in 2002, and the M.S. and Ph.D. degrees from the University of Maryland, College Park, MD, USA, in 2004 and 2007, all in electrical and computer engineering.

He is a Reader at the School of Computer Science & Informatics, Cardiff University. From 2007 to 2011, he was a Senior Researcher at the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. He is a coauthor (with John Baras) of the book Path Problems in Networks (Morgan & Claypool, 2010).

He received the Best Paper award at the ACM Workshop on Wireless Security, October 2004, for "Trust evaluation in ad-hoc networks" and the 2007 IEEE ComSoc Leonard Abraham prize for "On trust models and trust evaluation metrics for ad hoc networks." He coauthored the paper "Quantifying Location Privacy," which was runner-up for the 2012 PET Award (Award for Outstanding Research in Privacy Enhancing Technologies) and received a Test of Time award at 2021 IEEE Symposium on Security and Privacy.

Supervisions

I am open to new topics, but I am particularly interested in supervising PhD students on

  • security and privacy in IoT devices and networks
  • privacy in machine learning

Please look at my publications to see more details about the topics I am working on and about the methods I use in my research. I am more likely to supervise students that show me they have some idea of my research.
