AI × Cybersecurity
We study model privacy, machine unlearning and agent security to evaluate and protect AI systems. We also develop AI-assisted approaches to security analysis and response.
01 / RESEARCH DIRECTIONSFrom here, we connect with the world
Securing intelligence.
Connecting tomorrow.
We are UTSCybeR at the University of Technology Sydney. Our research connects AI, cybersecurity and communication to protect intelligent systems and improve the networks they rely on.
AI × Communication
We explore learning and adaptation in wireless and satellite networks, alongside resource management and accountability in 6G systems, to make connected infrastructure more reliable.
OUR FOUNDATIONS
Networks, IoT & Blockchain
02 / FEATURED PROJECTS
Research in practice.
We develop and test prototype systems for security analysis and adaptive communication.
