Cryptography engineer at EY Blockchain Hub and PhD Student at Ecole Polytechnique (Paris)

About

I am a cryptogrpahy engineer at EY Blockchain Hub and a PhD student at Ecole Polytechnique and INRIA Saclay under the supervision of Prof. Daniel Augot and Prof. François Morain in the project-team GRACE.

My work at EY focuses on developing cryptographic tools to address privacy and scalability issues in public blockchains. These tools include mainly zero-knowledge proofs, universal accumulators and proxy-reencryption schemes.

My PhD research focuses on pairing-based zero-knowledge proofs and friendly related cryptographic primitives.
