I am a professor of information security and computer networks at Worms University of Applied Sciences (founder of the network security research group and deputy scientific director of the Centre for Technology and Transfer). Before my professorship, I was a PostDoc at Fraunhofer FKIE and led a research team on smart building security. I received my Ph.D. (Dr. rer. nat.) and my Habilitation (Dr. habil.) from the Faculty of Mathematics and Computer Science at the University of Hagen in 2013 and 2020, respectively.

A list of my mostly academic 150+ publications can be found here. However, I also wrote books about the Linux operating system and contributed open source code/patches to the free software community. There is also a list of selected talks that I gave.

Research interests

Some of my key publications are focusing on information hiding taxonomy/patterns [1a], [1b], information hiding methodology [2], traffic normalization/wardens [3a], [3b], covert channel optimization [4a], [4b], scientometric citation analysis [5] and the security of networked IoT devices and smart buildings [6a],[6b],[6c],[6d].

I am a member of several steering committees, initiatives, program and organizing committees (cf. details. I am (or was) lecturing and supervising at Augsburg University of Applied Sciences, Bonn University and Hagen University. A list of my projects, both funded and spare-time software projects, is also available.

In addition to information security, I am interested in university history, campus novels, and retro computing – in particular: operating system history and historic network protocols. I own a small collection of rather historic books on these retro computing topics. Since about ten years, I am also a mid-distance runner (5km to half-marathon).
