About Me

I am an Assistant Professor in the Michton School of Computer Science at Brandeis University. My research focuses on the security and privacy of the web ecosystem, including browser fingerprinting, privacy-invasive attacks, and large-scale empirical analysis. My work explores real-world threats in deployed systems and develops defenses that are both practical and effective. Currently I am focusing in advanced tracking techniques that evade existing protections and the misuse of security policies in modern browsers.

I received my Ph.D. in Computer Science from the University of Illinois Chicago, where I was advised by Prof. Jason Polakis. Before that, I obtained both my B.Sc. and M.Sc. in Computer Science from the University of Crete, while working as a research associate at ICS-FORTH.
