    Transparent Proofs at Scale: Where the Constants Actually Go

    Nadia El-Mansouri researches zero-knowledge proof systems and their use in scalable, auditable infrastructure. Her recent work reduces prover time for general-purpose SNARKs by an order of magnitude and studies the trusted-setup question for transparent alternatives.

    Homomorphic Encryption Leaves the Lab: Lessons From Three Deployments

    Léa Fontaine works on lattice-based cryptography and fully homomorphic encryption, with a focus on making advanced primitives fast enough for deployment. She has co-authored reference implementations of several NIST post-quantum candidates and leads a research group on privacy-preserving computation.

    Small Devices, Real Adversaries: The State of Lightweight Cryptanalysis

    Marcus Adeyemi is a symmetric-key cryptanalyst known for practical attacks on lightweight block ciphers and for his work on the security of authenticated encryption in constrained devices. He chairs the working group on cryptographic standards for the African Union Commission.

    Threshold Cryptography for the Rest of Us

    Kenji Watanabe works on secure multi-party computation and threshold cryptography, bridging theory and standardisation. He has contributed to threshold signature drafts at NIST and studies the round complexity of maliciously secure protocols.
