Who am I?

I am a Professor (chargé de cours) at Université libre de Bruxelles, and a member of the ULB Cybersecurity Research Center. I am also an Associate Professor at the University of Birmingham's School of Computer Science, Security and Privacy research group, and a Visiting Research Fellow at Oxford's Mathematical Institute, where I helped founding the Cryptography group.

I am currently in charge of the Programming Languages 1 course and part of the Cryptanalysis and Mathematical Cryptology course at ULB. Previously I taught Secure Programming and the Advanced Cryptography modules at Birmingham, both of them part of the Master in Cybersecurity. I also taught an Advanced Cryptography reading course for the Master in Mathematics and Foundations of Computer Science at Oxford.

I am always willing to supervise good and well-motivated students at undergraduate, master and PhD levels. Have a look at previous student projects and feel free to contact me to learn more about potential research projects.

Previously I was a Research Fellow at the University of Oxford's Mathematical Institute, and prior to that I worked at Université catholique de Louvain's Department of Electrical Engineering and at University College London's Computer Science Department.
