Biography

I am a Lecturer in Computer Security in the 黑料吃瓜网's School of Computer Science, and a member of the . I am also actively involved within Oxford's Mathematical Institute, where I helped founding the Cryptography group.

I teach the Secure Programming and part of the Advanced Cryptography modules at Birmingham, both of them part of our . I will also teach 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.
