Education

  • Doctor of Sciences
    Sorbonne université & Université Libre de Bruxelles
    2022
    PhD Title: "Time Reversal Precoding with Artificial Noise Injection for Physical Layer Security" My PhD work proposed a new practical scheme to perform physical layer security (PLS) in the context of IoT and 5G. It aimed to secure IoT networks prone to passive eavesdropping while guaranteeing the reliability of the transmission to a legitimate user and preventing multiple passive eavesdroppers to correctly decode the data in a worst-case scenario, i.e., - A noiseless eavesdropper, - An eavesdropper equipped with an arbitrarily large number of antennas, - A transmitter imperfectly estimating the legitimated receiver's channel state information. I wrote multiple first-authors scientific papers in top-tiers journals (e.g., IEEE) and presented my work in world-class conferences all around the world (HawaĂŻ, Dublin, Paris...)
  • Master of Science (magna cum laude)
    Polytechnic School of Brussels
    2018
    Master of Sciences (Ms) in Electrical Engineering focus Electronics and Information Technology - Telecommunications (Signal Processing, Mobile & Wireless Communications, Digital Communications...) - Big Data, Machine Learning, Computer Vision - Project Management & Teamwork - Research Internship (3 months in Paris focused on Physical Layer Security) - Scientific writing (Master Thesis in Physical Layer Security - Grade: Summa Cum Laude)
