I'm a cyptography and security researcher at Brave. I specialize in privacy-enhancing technologies, lattice-based and multivariate-based cryptography, post-quantum cryptography, and real-world applications of zero-knowledge proofs. Previously, I contributed significantly to the Off-the-Record (OTR) messaging protocol and I'm a co-author the PQC Signature scheme "MAYO" submitted to NIST.
I also serve on the European review board at BlackHat and am a Free Researcher at KU Leuven. In addition, I am a member of the Advisory Council at the Open Technology Fund (OTF), and I server on various roles at the IETF/IRTF/W3C. I have also been involved in United Nations as an expert consultation, focusing on the intersection of human rights and technical standard-setting for emerging technologies.
