I am the head of the Study Center Computer Science at the RWTH Aachen University and affiliated Researcher at Media Computing Group. Until 2020 I was the deputy head (Akademischer Oberrat) of the Media Computing Group. My work and research interests are in a wide range of topics within the field of Human-Computer Interaction (HCI), including but not limited to ubiquitous computing, personal fabrication, touch input, interactive surfaces, and tangible user interfaces.

Before I started as a researcher, I received a Ph.D (2016) and a Diploma (2010) in computer science at RWTH Aachen University. 

For more details, take a look at my personal site: simonvoelker.net
I am also the coordinator of the board of examiners of the computer science department at RWTH Aachen University.
If you have any questions regarding the board of examiners please contact me via the online form of the computer science department.
