Eli Ben-Sasson

Formal First Name

Eli Ben-Sasson is the Co-Founder and President of StarkWare. He has been researching cryptographic and zero-knowledge proofs of computational integrity since 2001. His main interest lies in the mathematical foundations of computation and theoretical computer science, with a particular focus on computational complexity. His research has focused on formal proofs and their interaction with computation, including efficient probabilistically checkable proofs and their applications to verifying in a privacy-preserving manner the integrity of computations.

Professional Experience

Academic History


  • Ben-Sasson is a co-inventor of the STARK, FRI, and Zerocash protocols.
  • He has held research positions at the Institute for Advanced Study at Princeton, Harvard, and MIT.
  • Most recently, he was a Professor of Computer Science at Technion, which he left to co-found StarkWare.


  • Ben-Sasson is interested in understanding the intrinsic mathematical structure that leads to hard computational problems. 
  • His previous work focused on identifying combinatorial properties that lead to hard problems in different contexts of theoretical computer science, such as propositional proof complexity, algorithms for intractable (NP-complete) problems, and property testing. 
  • He continues to participate in the continuing investigation of the interplay between randomness and computation, which lays the foundations for modern cryptography.
  • He plays a fundamental role in the design of algorithms and computational complexity at large.



  • Ben-Sasson received his BSc and PhD in Computer Science from the Hebrew University of Jerusalem, Israel
  • He was an Amirin Scholar during his undergraduate studies.
  • During his graduate studies, he spent two academic years at the Institute for Advanced Study in Princeton, one of them as a participant in the special year on theoretical computer science. 
  • He won the Sire Charles Clore Fellowship for excellence in the natural sciences during his graduate studies.
  • He received the Dr. Shlomiuk Award from the Hebrew University for outstanding PhD research.
