My main research area is personal and digital fabcrication. This topic is about supporting everyday users in the process of transforming their idea into a physical object utilizing machines like lasercutters and 3D-printers.
Research in this area can be about solving difficulties that can arise during the designing and manufacturing process or exploring new possibilities and materials for digital fabrication.
As an HCI researcher I am focused on the human interacting with digital fabrication interfaces. I want to understand the challenges and provide new opportunities and methods for users in digital fabrication spaces.

Thesis Supervision Topics

This are currently open thesis topics

  • I currently have no open topic
  • Additionally, I am always interested in your own research ideas in the area of personal fabrication.

To learn more about research methods in HCI we always recommend the book with the matching name Research Methods in Human-Computer Interaction.
If you are interested in doing a B.Sc. or M.Sc. thesis with me, drop me an email with your résumé, grade sheet(s), and idea(s) that interest you.

Fab:UNIverse Zukunftsvisionen der Maker Bewegung
Workshop organized by the VINN:Lab at TH Wildau about the future of Fab Labs with a university context.
Discussed topics:
  • What is the difference from Fab Labs with a university context to general makerspaces
  • Which chances are provided by the university context and how can we learn from each other
  • Which purpose/function do we have in the maker movement and how can the movement evolve
