I'm a husband, father of three, (amateur) tenor singer, and a Cryptography Engineer at Nillion.

• 🔭 I’m currently doing applied research in cryptography, focusing on MPC and zkTLS, while also developing Nada, a programming language for Secure Multiparty Computation.

• 🎓 I hold a Ph.D. in Information Security from the University of Lisbon, Técnico, under the supervision of Dr. Paulo Mateus. I also earned an M.Sc. in Applied Mathematics from Imperial College London, where I studied Condensed Matter Theory under the supervision of Dr. Ryan Barnett. I hold a B.Sc. in Applied Mathematics and Computation from Técnico, University of Lisbon.

• 🧪 Previously, I was a Quantum Cryptography Researcher at Tekever, where I led the technical design and execution of research proposals at the intersection of Secure Multiparty Computation and Quantum Communication. I was also responsible for establishing R&D partnerships with institutions such as Thales, Imperial College London, and Fraunhofer HHI.
