About

Joshua D. Ibrahim is a rising authority in the security and resilience of cyber-physical systems, with a sharp focus on the detection and mitigation of stealthy adversarial threats. His research centers on zero dynamics attacks (ZDAs)—among the most insidious forms of cyberattacks targeting robotics, aerospace, and industrial control networks. In his landmark 2024 work, "Robust Optimal Network Topology Switching for Zero Dynamics Attacks," Ibrahim pioneered a framework that dynamically reconfigures network architectures to neutralize both intrinsic and enforced ZDAs, a contribution that has already garnered early citations for its practical, real-time defense capabilities. By exploiting vulnerabilities in internal dynamics, discretization, and asynchronous actuation, his work addresses critical gaps in securing autonomous systems against attacks that evade conventional detection. Though early in his career, Ibrahim’s targeted, high-impact research signals a transformative approach to safeguarding the next generation of interconnected, safety-critical infrastructures.
