Research Interests

I am interested in information security aspects of practical systems. In particular, I am currently working on security of industrial control systems and the Industrial Internet of Things, for applications such as public infrastructure (e.g., public water systems and power grids). At SUTD, I was involved in the construction and operation of several of our practical testbeds in those areas (SWaT, WADI, EPIC). In addition, I have worked on physical layer security aspects of wireless and embedded systems, for example secure ranging, distance measurements and communication using wireless signals. I continue to work in those areas in the context of (I)IoT security. I also designed and implemented the "cloud" backend of the National Science Experiment, a project with 50,000 mobile sensors deployed in Singapore, used by more than 90,000 students to date. For three years, I co-organized the Secure Cyber-Physical Systems Week event at SUTD. I also co-organized the BATADAL competition for physical process attack detection algorithms.
