Welcome to my homepage! I am a 2nd year Phd student in the Computer Science Department at Brown University under the supervision of professor Anna Lysyanskaya.
Before coming to Brown I got my Bachelor from the department of Applied Informatics, University of Macedonia, Thessaloniki, Greece where I was working as a member of the cryptography group at the Computational Systems and Software Engineering Laboratory.
You can find my CV here.
