I am a Doctoral Researcher in the Information Security Group at University College London, where I study security and privacy aspects of digital ecosystems, with a focus on emerging technologies and previously unknown attack vectors. My supervisors are Professor George Danezis and Dr. Emiliano De Cristofaro.
My recent study on ultrasound tracking received wide-spread attention and is considered the seminal work on the security of that ecosystem. Currently, I am working towards the standardization of ultrasound communications, and design extensions of my previous attacks. Moreover, in cooperation with industrial partners, I recently released a prototype of a high-assurance hardware architecture, that maintains its security properties even in the presence of malicious hardware components.
In the past, I developed auditing tools for the Public Key Infrastructure of Deutsche Bank and participated in an international consortium studying large-scale security threats in telecommunication networks. Furthermore, I cooperated with the Computer Security Group of University of California, Santa Barbara in several projects, including a detection system for evasive web-malware.
I hold an M.Sc. in Information Security from UCL, and a B.Sc in Computer Science from University of Macedonia, Greece.
