Other Activities

From 2003 to 2005 I tought once a year the course "Softwarevisualisierung -- Methoden und Werkzeuge, Möglichkeiten und Grenzen" (together with Stephan Diehl) for the "Deutsche Informatik Akademie". The goal of this course was to transfer knowledge from academia to industry.
I am member of ACM and IEEE.
