Dimitri Lajou

Je suis actuellement ATER à l'IUT de Bordeaux dans le département Informatique (BUT et DUT). J'enseigne à l'IUT depuis 2018. Je suis parallèlement en thèse au LaBRI dans l'équipe Graphes et Optimisation. J'effectue cette thèse sour la direction de Hervé Hocquard et Éric Sopena sur les colorations de graphes. Ma soutance est prévu pour le vendredi 10 décembre à 10h.

Enseignements

2021-2022: ATER à l'IUT de Bordeaux. Les enseignements de S1 et S2 ci-dessous sont effectués au sein du BUT informatique, les enseignements de S3 et S4 concernent le DUT informatique. De septembre 2018 à août 2021, j'ai donné des cours au sein du DUT informatique de l'IUT de Bordeaux en tant que doctorant contractuel.
