Natalia Silberstein


I am currently a Postdoctoral Researcher at the Technion - Israel Institute of Technology, the Department of  Computer Science. I am working with Prof. Tuvi Etzion.

From 2011 to 2013 I was  a Postdoctoral Fellow i
n Wireless Networking and Communications Group, at the University of Texas, Austin. Host: Prof. Sriram Vishwanath.

In  2011, I received a PhD. degree in Computer Science from the Technion - Israel Institute of Technology,  under the supervision of  Prof. Tuvi Etzion.

I received my M. Sc. in Applied Mathematics in 2007, and B.A. in Computer Science and B.A. in Mathematics in 2004, from the Technion.


My research interests include coding for distributed storage systems, network coding, algebraic error-correcting codes, applications of combinatorial designs and graphs to coding theory.
