I am head of the Computer Science Study Center and coordinator of the Examination Committee for Computer Science at RWTH Aachen University.

I am also an Affiliated Researcher at the Media Computing Group of the RWTH Aachen. Between 2016 and 2020, I was deputy chair of the Media Computing Group. My research area is Human-Computer Interaction (HCI) and I mainly work on mobile interactions, ubiquitous computing, personal fabrication, touch input, interactive surfaces, and tangible user interfaces.

I am in charge of the following responsibilities:

  • Examination board computer science
  • Coordination of the teaching of the computer science department

Students can submit requests to the Computer Science Examination Board via web form.
