I am a Postdoctoral Researcher at the Efi Arazi School of Computer Science, Hosted by the FACT Center
Prior to that, I was a Postdoctoral Researcher at the
College of Computer and Information Science at Northeastern University, hosted by Associate Prof. Daniel Wichs
I received my Ph.D. from the Computer Science Department at the Technion, where I was very fortunate to have Prof. Yuval Ishai as my advisor. 

My research area is Cryptography, but I am also interested in Theoretical Computer Science in general.

Theory Seminar

During the years 2012-2015 I organized the CS Theory Lunch at the Technion. The seminar is now organized by Ron Rothblum. You are welcome to contact him directly at (rothblum@cs.technion.ac.il) if you are interested in joining the seminar's mailing list, or in giving a talk at the seminar.

Women @ CS

    During the years 2013-2014 I was part of a team for the integration and advancement of female students at the CS department at the Technion.
