My name is René and I joined the Media Computing group in late 2020 as a Research Assistant. Currently, my main focus is on textile interfaces (see our RIME project).
Additionally, I am fascinated by dark patterns and started researching how we can deal with such malicious designs on the user's side.
Research Projects
Administrative Role
I am the i10 librarian. This includes maintaining the software for labeling books, maintaining publications, maintaining the CHI rankings page, and keeping the Hochschulbibliothek up to date. More information can be found on the Librarian page.
Additionally, I took over the coordination of our Fab Lab from Marcel Lahaye.
