Master's Internship
I co-supervised, with Sorina Ionica, a student in their second year of Master's studies on the topic of computing multiple elliptic curve discrete logarithms using the Parallel collision search algorithm by van Oorschot and Wiener.

Undergraduate internship
I co-supervised, with Gilles Dequen, a student in their third year of Undergraduate studies in CS. The student was working on a commercial presentation (website, explanatory animations) of the CrypTonAuth authentication technology and on storage solutions.
