Congratulations to Majed Jaber, who defended his PhD thesis, “Structural and spectral analysis of dynamic graphs for attack detection”, on 19 December 2025 at the University of Strasbourg (ICube laboratory), under the supervision of Pierre Parrend and Aline Deruyver. The jury included Marc-Oliver Pahl, Véronique Legrand, Mohamed-Lamine Messai, and Rushed Kanawati.
The thesis introduces a spectral and structural graph-based framework for detecting cyberattacks in dynamic, heterogeneous networks — including the Spectral Time-Windowing method, the BiFlowness metric, and the open-source GPML library — building on work also presented in Graph-Based Spectral Analysis for Detecting Cyber Attacks (ARES ‘24) and Cyberattack detection through GPML: Graph Processing for Machine Learning (SoftwareX).
