I am a german mathematician and mostly active on the german Wikipedia since the beginning of 2004. I was a member of the board of Wikimedia Deutschland e. V. from 2006 till 2010. I am particulary concerned with methods to improve the quality of Wikipedia, in particular I was responsible for Flagged Revisions.
