Summary
👤
Senior🎓
Top SchoolAriel Gabizon is a cryptographer and founder focused on practical zero-knowledge systems, currently serving as Chief Scientist at Aztec after leading research and engineering efforts at Zcash and Protocol Labs. With a PhD in Computer Science and over nine years of experience, he has driven production-grade zk-SNARK work including simplifying MPC setups for parameters and identifying critical security vulnerabilities in live protocols. His background spans deep theory and deployment—postdoctoral research at Technion and Columbia to building and benchmarking core Zcash transaction and signature code—giving him a rare fluency across math, proofs, and systems. He is fascinated by how algebraic tools like elliptic curve pairings enable nuanced tradeoffs between privacy and verifiability, and he continues to push those tools toward real-world cryptographic infrastructure.
