Alexandre Berthet

PhD Student - Image Processing and Deep Learning



Alexandre Berthet is currently PhD student in Digital Security at EURECOM – Sophia Antipolis since September 2019, with Professor Jean-Luc Dugelay as supervisor, working on DEFACTO project, whose subject is “Digital Image Forensics with Deep Learning”.

During his Master’s project, Alexandre worked in collaboration with EFREI Paris (Digital Engineers School) and Sorbonne University – Sciences Faculty, on the realization of an intelligent system for automated data collect on an apiary. The proof of concept made by Alexandre is integrated in the project projet « PNAPI » (Plateforme Numérique d’accompagnement des APIculteurs), laureate of CASDAR RT 2018.

During his first Master’s year, Alexandre worked in Laboratoire d’Informatique de Paris 6 (LIP6), in SoC department (Système On Chip) and more specifically in SYEL team (Systèmes Electronique). He contributed on SpinalCOM project, under Sylvain Feruglio’s direction via the realization of spectral discrimination’s methods of an optical sensor CMOS for the spinal cord’s monitoring.
