Applied Cryptographer & Researcher

Co-Founder at Zero Savvy Ltd | Research Fellow at University of Warwick

Shahriar Ebrahimi

I am a Co-Founder of Zero Savvy Ltd and a Research Fellow at University of Warwick. Prior to this, I was a PostDoc at Newcastle University in the UK and at IDEAS NCBR in Poland. I earned my Ph.D. in Computer Engineering from Sharif University of Technology back in 2021.

I have had the opportunity to lead blockchain projects in the cryptocurrency industry, where I worked on decentralized exchange systems and secure large-scale wallet implementations. My research focuses on practical applications of cryptographic protocols, including Zero-Knowledge Proofs (ZKP), Multi-Party Computation (MPC), and privacy-preserving machine learning.
