About me
I received the B.S. degree at University of Cagliari in pure Mathematics and the M.Sc. degree at University of Trento in Coding Theory and Cryptography. I got my Ph.D. degree in Computer Security at Univeristy of Bergen, Norway, under the supervision of professor Igor Semaev. Since February 2022, I work at the Cryptography Research Center of the Technology Innovation Institute in Abu Dhabi.
I am always interested in hearing from colleagues, other cryptography fans, or just interesting creative folk, so feel free to contact me.
Hobbies: photography, skiing (downhill and cross-country), hiking, surfing (when I can), climbing. Also, I have been a semi-professional juggler and performed in international juggling conventions and festivals.
Research Interests
> Cryptoanalysis
> Code/Lattice-Based Cryptography

Open Source Coding
You can find here a library that compares different methods to sample random permutations.
I am the creator of the rbbl (RAM-Based BKW for LWE) library: a fast and parallelized library written in C to solve LWE instances.
I am one of the creators of the fbbl (File-Based BKW for LWE) library. This is the first implementation of the BKW algorithm for LWE able to solve relatively large LWE instances.
I have been mantaining the Apache milagro-crypto-c and milagro-crypto-js libraries.
