About me
I received my PhD in Provable Security and Privacy from Aalborg University, Denmark and I currently work as an Associate Professor at the Department of Computing Sciences where I also lead the Network and Information Security group (NISEC). The group comprises PhD students, professors a nd researchers. Group members conduct research in areas spanning from the theoretical foundations of cryptography to the design and implementation of leading-edge efficient and secure communication protocols. Apart from my research work at NISEC, as an associate professor, I am actively involved in the teaching activities of the University. Finally, my role expands to student supervision and research project coordination.
