He develops methods for the statistical analysis of dynamic social network data, and publishes theoretical-empirical work on network dynamics in different sub fields of sociology. Both research lines have been featured in leading sociological and methodological journals (e.g. Sociological Methodology, Sociological Methods & Research, Social Networks, Social Forces). To make the methodological work accessible to the applied social networks community, Christoph Stadtfeld develops and contributes to scientific software packages, like the Goldfish package in R.
