I am looking for bright and highly motivated PhD students who are interested in working with me on exciting new problems in cryptography [more info].

About Me    [CV]

I am an assistant professor at the department of computer science at Northeastern University. I am affiliated with the theory and security groups.
My main research area is cryptography. Some of the topics I work on are: Aside form the above, I pursue research in all other aspects of cryptography, spanning the full spectrum from theory to practice.
I am also interested in computer security, algorithms, complexity theory, coding theory and information theory.

Prior to joining Northeastern, I was a Josef Raviv Memorial Postdoctoral Fellow
at IBM Research T.J. Watson.

I got my PhD in Computer Science at New York University (NYU) in 2011.
I was very fortunate to have Yevgeniy Dodis as my advisor.
I got my Bachelor's degree in Mathematics and Master's degree in Computer Science at Stanford University in 2005.
