Current position

I am the Lecturer (Asst. Prof.) in Networks and Security at the University of Sydney and an Academic Visitor at the University of New South Wales. I also collaborate closely with Data61 (CSIRO), Australia's premier ICT innovation group.

As an adjunct member of this Chair, I continue to advise some topics. From time to time, I can offer Bachelor's/Master's theses in Australia in collaboration with TUM, aimed at outstanding students with an interest to broaden their horizon.  Please contact me directly if you are interested - and also allow ample time for an application (at least 6 months).

There are also opportunities to do a PhD with me in Sydney - applications are competitive. PhDs come with a scholarship and can be carried out in collaboration with Data61 (these are closer to industry and come with a top-up). If you wish to pursue research in Australia, please write me an email and allow enough time for an application (7+ months).

My current personal homepage is here.

Research Topics:

My research interests revolve around network measurement and security, with a decidedly empirical approach. My current interests are:

  • Global-scale measurement of Internet service deployments and their security
  • Data-driven security mechanisms
  • Analysis of blockchain technology and its implications

My topic is real-world security: Security is achieved only by technology that its supports human users. No matter how brilliant the technology, if humans find it hard to operate, it will be insecure. Similarly, technology is always used in a context (at home, in finance, etc.) and this context is important in understanding how a technology must designed.
