I am a Postdoctoral Researcher at the College of Computer and Information Science at Northeastern University, working with Assistant 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 Complexity Theory in general. More specifically, my research focuses on secure computation, zero-knowledge and efficient verification protocols.
I have also worked on the following topics: 
  • Protocols for secure multiparty computation over incomplete networks (during a summer internship at the Cryptography group at IBM Thomas J. Watson Research Center, summer 2015).
  • Program obfuscation (during a summer internship at UCLA, summer 2014). 
  • Practical aspects of (format-preserving) encryption schemes (during an internship at the Privacy Information and Security group at IBM research lab, Haifa, summer 2013).

Theory Seminar

During the years 2012-2015 I organized the CS Theory Lunch at the Technion. The seminar is now organized by Ami Paz. You are welcome to contact him directly at (amipza@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.
