About

My research focuses on privacy-preserving computation using lattice-based cryptography, a type of post-quantum cryptography.

Projects

(Sunscreen, 2021 - present)

Privacy-preserving smart contracts: using fully homomorphic encryption (FHE) + zero-knowledge proofs (ZKPs) to hide the inputs/outputs of smart contracts
(NuCypher, 2019 - 2021)

Anonymous reputation systems: using lattice-based group signatures to review products anonymously
(Oxford, 2017 - 2018)
