Manuel Barbosa
I am an Associate Professor at the Department of Computer Science in the Faculty of Science of the University of Porto (DCC-FCUP) and a researcher at HASLab/INESC TEC. My research interests lie in Cryptography and Information Security and its intersection with Program Verification.
I hold a Ph.D. in Electrical and Electronic Engineering from the Newcastle University, an M.Sc. from the same University, and a degree in Electrical and Computer Engineering from the Faculty of Engineering of the University of Porto. In the past I have been a visiting researcher at the University of Bristol, IT Porto and École Normale Supérieure. Between 2023 and 2025 I was a research fellow at the Max Planck Institute for Security and Privacy.
I have been working on the development of high-assurance cryptographic implementations for the last 20 years, aiming to bridge the gap between theoretical security and real-world security. I am particularly interested in provable security and its interplay with the formal verification of cryptographic proofs and cryptographic software implementations.
