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.

About me

I started as a cryptographer at SSH Communications Security in 1997 and I am still on that path. I have also worked in more general technical information security consulting and security assessment roles. I did my Ph.D. in the United Kingdom (ISG, Royal Holloway, University of London in 2009). 

Responsibilities

In addition to regular academic tasks (research activities, teaching, supervision of theses, subject matter expert roles), a Professor of Practice in Information Security helps the university and its students to meet the evolving requirements of industry, businesses, and the state and acts as a technical contact person in research projects and curriculum development.

Field of expertise

My core competencies are in applied cryptography, cryptographic engineering, and security assessments (including cryptanalysis.)

About me

I received my M.Sc. Degree in Computer Science from Politecnico di Torino in 2011. During my studies I had the great opportunity of participating in the Erasmus Programme, being hosted in Espoo by Aalto University (at the time it was transitioning from TKK/HUT to Aalto University). There I had a chance to work under the supervision of Billy Bob Brumley and Kaisa Nyberg, working on Software Side-Channel Attacks on Cryptographic Implementations, which later evolved in my current Doctoral Research Project.
