Research

My research focuses on advancing the security, resilience, and trustworthiness of intelligent cyber-physical systems (CPS) operating in adversarial and safety-critical environments. I develop secure and explainable AI-driven architectures for autonomous vehicles, edge intelligence, connected infrastructure, healthcare AI, and distributed cyber-physical systems. My work integrates cybersecurity, real-time systems, machine learning, and embedded systems to build intelligent systems that remain reliable under attack, uncertainty, and resource constraints.
