Research Interest
My research interest is in the field of cryptography, with a focus on secure multiparty computation
(MPC). My research concentrates on the question of feasibility. This includes the question of what
cryptographic tasks can and cannot be realized under what cryptographic assumptions, and is related
to theoretical foundations of cryptography. In particular, my main interest is in achieving fairness
in secure computation. In addition, I am also interested in efficiency of MPC, and closing the gap
between the theory and practice of MPC. This includes the design of new realistic models that enable
constructions and protocols with high efficiency. I am also interested in the intersection between GameTheory and Cryptography.
