What I do in one sentence:
I am a postdoctoral researcher and lecturer in English linguistics at the
University of Düsseldorf and a developer
at the
University Library Center (hbz) in Cologne, who is interested in computer-mediated communication,
the use of social software (especially in institutional contexts) and in how the Internet is reshaping scholarly communication.
Still not very short, but it *is* a single sentence :-)
