What are the specific areas of your graduate education?
My Ph.D. was in Computer Science, where I conducted research in the field of Cryptography. My M.Sc. was in Mathematics, in the field of Algebraic Geometry.
What are your research interests?
I am interested in all aspects of Cryptography, especially in Secure Multiparty Computation (MPC), where a set of distrusting parties jointly compute a function while guaranteeing privacy of the inputs and correctness of the output. In my graduate studies I analyzed various security properties of MPC protocols both in terms of feasibility and in terms of efficiency.
What’s one problem you’d like to solve with your research/work?
One of the questions I’m interested in nowadays is understanding the minimal and necessary requirements for executing secure protocols. One aspect of this question is analyzing the basic properties of the communication graphs induced by secure protocols, and check, for example, whether such graphs must be expanders.
What aspect of what you do is most interesting?
The most fascinating thing about modern cryptography, in my opinion, is the ability to provide “magical” solutions to seemingly unsolvable day-to-day problems. For instance: How to collaborate without trusting anybody. How to compute over data without knowing what the data is. How to prove knowing a secret without revealing any information about it.
What are your research or career goals, going forward?
I enjoy conducting research and solving challenging open problems, as well as teaching and working with students. I hope to combine both of these aspects in an interesting academic career.
