I am Evgenios (pronounced ev-YEN-ee-os) and I am an Assistant Professor in the Computer Science Department at George Mason University. My research is in computer security and applied cryptography and focuses on analyzing and designing efficient encrypted systems using techniques from cryptography and algorithms. I am the head of the Encrypted Systems Group at George Mason.

Before Mason, I was a postdoctoral researcher at the EECS Department at UC Berkeley working with Dawn Song from 2019-2021. I obtained my PhD in 2019 from the Computer Science Department at Brown University working under the supervision of Roberto Tamassia. My doctoral dissertation received the Joukowsky Outstanding Dissertation Award from the Graduate School of Brown University.

Openings: Our Encrypted Systems Group has openings for motivated Ph.D. students with focus on applied cryptography. Please contact me if you are interested in joining the group.
