short bio

Olaf M. Maennel

The Internet has revolutionized the way in which we communicate, do business, or learn. Knowledge is now easier to access than ever, and what fascinates my research is the technology that enables this worldwide paradigm change.

Since July 2014 I am a Professor for Cyber-Security at Tallinn University of Technology in Estonia. Before that i was with Loughborough University in UK and with the University of Adelaide in Australia. My interests are in security, focusing on:

  • network security
  • serious games
  • big data analytics
  • critical infrastructure protection
  • routing (BGP, IS-IS)
  • measurements (active & passive)
  • IPv6 & IPv4 address sharing technologies
  • future Internet technology & network virtualization
  • abstractions of networks for configuration management systems

I obtained my Ph.D. (Dr. rer. nat.) in computer science from the Technical University of Munich, Germany, in the group of Anja Feldmann in 2005 and my Diploma (MSc) from the Saarland University, Saarbrücken, Germany.


High-quality research should build on solid theoretical foundations, but must also deliver real-world impact. For example, I am working with Tim Griffin on routing algebras that ensure robustness and safety of Internet routing. However, without close collaborations with Internet Service Providers (ISPs) and router vendors, such research will not find its way into the real network.

This dialog with industry is very important to my research, as it ensures research will not lose it's foundations. During my PhD I have worked with Anja Feldmann and Rüdiger Volk from Deutsche Telekom on a network-wide configuration management system, which is in production use in DT's network since 2004. The system specifies eBGP routing policies on an abstract graph-level, but then compiles it all the way down to the vendor-dependant code and auto-configures their routers.

At the University of Adelaide in South Australia I did my post-doc in the School of Mathematical Science working with Matthew Roughan. I am still continuing collaborations with my friends "down under". At the moment we are extending our configuration management system to be beneficial to the network security area as well, for example to configure and auto-deploy Cyber Defense Exercises.

It is this balance between theory and "hands-on" that enables innovation and changes technology.


What drives my research also applies to my teaching. Personally, I believe that traditional universities are at risk of sleepwalking into a crisis, as Massive Open Online Courses (MOOCs) change the higher-education environments drastically (my view on teaching in the information age). We need to rethink our methods/values and implement innovative teaching into our programs. I have also recently been involved in the restructuring of our postgraduate Internet Computing and Network Security (ICNS) program.

Since April 2012 I am a Fellow of the UK Higher Education Academy (HEA) having completed the HEA accredited "New Lecturers' Course", which is a comprehensive course for new academic faculty in UK.
