Rafael Pass

Summary

I am a Professor in the Theory of Computation Group of the Blavatnik School of Computer Science at Tel-Aviv Univeristy and the incumbent of the Chair in Cryptography and Information Security. I serve as the Director of the Checkpoint Institute for Information Security. I am also a Professor (on-leave) at Cornell Tech and in the Department of Computer Science at Cornell University. 

I obtained my Ph.D in 2006 in the Theory of Computation group at MIT with Silvio Micali as advisor. 

Previously, I completed my Licentiate Thesis (M.S.) under the supervision of Johan Hastad. 

My research focuses on Cryptography and its interplay with Computational Complexity and Game Theory; lately, I have become interested in the theoretical foundations of blockchains, and even more recently on connections between Cryptography and Kolmogorov complexity (some recent media coverage about this line of work: [quanta] [quanta] [quanta-science-podcast] [info-security-mag] [pour-la-science]; and here is a lighter pop-sci podcast that includes interviews with Diffie and Hellman [Vox])

My work has been supported by a NSF Career Award, a Microsoft Faculty Fellowship, an AFOSR Young Investigator Award, an Alfred P. Sloan Foundation Fellowship, a Wallenberg Academy Award, a Google Faculty Award, a JP Morgan Faculty award, as well as grants from AFOSR, BSF, DARPA and IARPA. 

I am an ACM Fellow and an IACR Fellow.
