I am a professor of information security and computer networks at Hochschule Worms, where I am also the scientific director of the Center for Technology and Transfer. In addition, I am a lecturer at the University of Hagen. Before my professorship, I was a PostDoc at Fraunhofer FKIE in Bonn, where I 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 170+ mostly academic publications can be found here. However, I also wrote non-academic 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 [CSUR’15], [CUING’21], [AsiaCCS’22], information hiding methodology [JUCS’16], traffic normalization/wardens [FGCS’18], [IJAS’12], covert channel optimization [CMS’11], [CMS’12], scientometric citation analysis [Scientometrics’20] and the security of networked IoT devices and smart buildings [ACCESS’19],[SEC’15],[JCSM’17],[CACM’16].

I am a member of several steering committees, initiatives, program and organizing committees (cf. details. I am (or was) lecturing and supervising at Bonn University, FernUniversität in Hagen and Hochschule Augsburg. 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. Sparetime: different kinds of sports.
