  • Teaching:

    Since 2016/2017, I teach at the département QLIO of IUT Nice Côte d'Azur:

    • 2018- : Sécurité des systèmes d'information (LP MPL).
    • 2017- : Systèmes de gestion de bases de données (DUT QLIO S3).
    • 2016- : Recherche opérationnelle (DUT QLIO S4).
    • 2016-2017 : Systèmes d'information et logistique (DUT QLIO S3).

    Some materials of my previous teaching activities are gathered on this page.


  • Code-related stuff:

    • A nice page for playing with augmenting paths (w/ J. Belmon & V. Garnero).
    • A list of all non-isomorphic planar push cliques (w/ S. Nandi & S. Sen).
    • Some algs I use for solving the Rubik's cube :) .
