About me


I am a Security Engineering Manager at Meta (fka Facebook). I support a distributed team of highly skilled engineers who work on systems and infrastructure that provide a range of capabilities for security investigations. I joined the company in 2014 as a Threat Research Scientist and worked on providing a better understanding of the threat ecosystem targeting the Facebook Family of Apps. 

As of the 2023 Fall semester, I am also an Adjunct Instructor in the Information Networking Institute (INI) at Carnegie Mellon University (CMU)


In August 2014 I received a PhD in Engineering and Public Policy (EPP) from CMU. I worked on empirical measurements and economic modeling of online crime, towards understanding and structuring effective countermeasures. The title of my PhD thesis is Structuring Disincentives for Online Criminals. In this effort I was fortunate to be advised by Nicolas Christin and funded by CyLab.

I hold a B.Sc. in Computer Science, and an M.Sc. in Information Systems from the Athens University of Economics and Business (AUEB).
