About Me

My work focuses on designing efficient and secure cryptographic protocols — particularly in threshold cryptography, privacy-preserving authentication, secure multiparty computation, and lattice-based schemes — with the goal of bridging theoretical foundations and real-world deployable systems. My research has applications in blockchain security, financial systems, anonymous credentials, and privacy-enhancing technologies.

Research Interests

Threshold cryptography (threshold signatures, best-of-both-worlds designs, dishonest-majority settings)
Privacy-preserving authentication and processing of encrypted/authenticated data
Secure multiparty computation with improved efficiency (rounds, communication)
Lattice-based cryptography and cryptanalysis (covert channels, anonymous tokens)
Anonymous tag systems, rate-limiting nullifiers, double authentication preventing signatures
Applications to blockchain, central bank digital currencies (CBDCs), and witness encryption
