I am a faculty at the CISPA Helmholtz Center for Information Security since August 2018. Before that, I was an Assistant Professor at the Information Systems Technology and Design Pillar, at the Singapore University of Technology and Design (SUTD). I earned my Dr. Sc. in Computer Science from ETH Zurich (Switzerland) in 2012. At ETH, I was part of the System Security group led by Prof. Srdjan Capkun. Before my studies at ETH, I received a degree in Computer Engineering (Dipl. Ing.) from the Hamburg University of Technology (Germany) in 2007. My thesis on side-channel attack-resistant embedded crypto was supervised by Prof. Dieter Gollmann (TUHH), and Dr. Heike Neumann (NXP). The thesis won the K-H Ditze award for TUHH’s best thesis in 2007. I was also awarded a DAAD scholarship to study for one year at the University of Waterloo, Ontario, Canada between 2004-2005. My full CV is available here.

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.

I co-founded SUTD’s kopipacket CTF team, and currently practise my applied security skills by particpating in CTF events together with Saarsec.


I serve(d) as PC member on conferences such as Usenix Security, CCS, Esorics, ACNS, and Wisec; and as reviewer for journals such as TIFS, TOPS, Sensors, TWC, TII. More info here.


I am currently teaching the core lecture Security in the Winter term, and the advanced lecture on Physical-Layer Security in the Summer term. I also support the Perspectives on Cybersecurity and Hacking classes with content and guest lectures.
