Intro
My name is Evgenios (pronounced ev-YEN-ee-os) and I am a postdoctoral researcher at the EECS Department at UC Berkeley working under the mentorship of Dawn Song. I am a member of the Security Group at EECS Department. I obtained my PhD from the Computer Science Department at Brown University under the supervision of Roberto Tamassia.
My research is in computer security and focuses on analyzing and designing efficient encrypted systems using techniques from cryptography and algorithms. Other recent ongoing projects include secure computation and adversarial inputs for machine learning algorithms. In the past I have worked on various problems with strong algorithmic component.

Music
Studied classical guitar in my home town, Rhodes, at the Hellenic Conservatory. I continued my musical studies in Crete at the Sychronon Conservatoire of Crete. In 2010 I obtained my professional classical guitar degree from a committee comprised of guitar virtuosi Evangelos Assimakopoulos & Liza Zoe and conductor Theodore Antoniou.
