About Me
I am a Research Fellow in the Department of Software Systems and Cybersecurity at Monash University, with a primary focus on the cybersecurity of cyber-physical systems (CPS). My research interests lie in securing critical infrastructure, including smart energy systems and cellular networks, where the adoption of these technologies is rapidly expanding. The distributed nature of these systems presents significant challenges for central control, as data and control sources often reside outside traditional perimeters.
Research Interest
- Data integrity attacks
- Cellular/O-RAN security
- Security of CPS
- Self sovereign identity
- Applied ML
