I have applied these methods in a variety of domains, including public health, education, developmental psychology, and intra- as well as inter-organisational studies. I am currently working on applications to bigger data sets obtained from population registers, stock markets, and social media. My main research interest is currently the empirical study of emergent macro- and meso-level phenomena in social networks, e.g., segregation, hierarchies, or subgroups. In this work, I combine empirical calibration of models to data sets for purposes of statistical inference with empirically informed simulation studies.
