some personal information about me.


selected papers, tools, projects.


research overview and publications.

academic activities.

services on committees, boards, etc.


Tenured researcher and team leader in Computational Social Science (at GESIS in Köln, Germany).

Current research focus: Making modern Data Science methods (mostly NLP and Machine Learning) more valid, reliable and understandable for research about social phenomena. But I'm also interested in Human Computation and online communication and collaboration.
