Shahriar Ebrahimi
Applied Cryptographer & Researcher
Founding Member @ Zero Savvy Ltd | Research Associate @ the Alan Turing Institute
I am a Founding Member of Zero Savvy and a Research Associate at the Alan Turing Institute. Prior to this, I was a PostDoc at Warwick and Newcastle universities in the UK and at IDEAS NCBR in Poland. I earned my Ph.D. in Computer Engineering from Aryamehr (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.
