About

Dr. Joudi Hajar is a leading researcher in the security and resilience of cyber-physical systems, with a primary focus on robotics, aerospace, and networked control. Her most-cited work, "Robust Optimal Network Topology Switching for Zero Dynamics Attacks" (2024, 2 citations), tackles one of the most insidious threats in these domains: zero dynamics attacks (ZDAs). Dr. Hajar’s major contribution lies in developing robust, optimal strategies for dynamically switching network topologies to neutralize both intrinsic and enforced ZDAs—attacks that exploit internal dynamics, discretization, and asynchronous actuation to remain stealthy. By providing a formal framework for reconfiguring system architectures in real time, her research offers a proactive defense against attacks that traditional detection methods often miss. This work is pivotal for ensuring the safety of autonomous vehicles, industrial control systems, and critical infrastructure. Dr. Hajar’s innovative approach to attack-resilient control has quickly garnered attention, establishing her as a rising authority in cybersecurity for complex engineered systems. Her research not only advances theoretical understanding but also delivers practical solutions for safeguarding next-generation autonomous technologies.
