Welcome to the homepage of Christian Steglich
Who I am
I work as a mathematical sociologist and network researcher at the Interuniversity Centre for Social Science Theory and Methodology (ICS, Department of Sociology, University of Groningen) and at the
Institute for Analytical Sociology (IAS, Department of Management and Engineering, Linköping University).

What I do
My research focuses on the formal modelling and inferential-statistical analysis of socio-centric social networks, and - since short - on the network analysis of register data.
My published work is focused on the formal modelling of social network structure and social network dynamics, with emphasis on social influence processes in the context of a changing network. Over the years, my work has shifted to a broader orientation, including networks in educational settings, the co-evolution of multiple networks, and the analysis of emergent macro- and meso-level phenomena by micro-level modelling, such as normative behaviour, social hierarchies, and subgroup structures in networks.
In my work, I combine empirical calibration of models to data sets for purposes of statistical inference with empirically informed simulation studies. Far too often in empirical network research, hypotheses are formulated with insufficient consideration of what the null hypothesis should be. In social simulation studies, a related predicament is the study of simulated networks that do not match their empirical counterparts on important dimensions.
Some temporally close events and activities that I will be (or recently have been) involved in are these:
- Together with Åsa Wallhagen and Niclas Lovsjö, I am organising the 9th Winter School on Longitudinal Social Network Analysis & Advanced Siena Users' Meeting (ADSUM-2017) that will take place at the Norrköping campus of Linköping University in the week of 6-10 February 2017. Teachers of the course will be Tom Snijders, Johan Koskinen and Per Block (all AdSUM) and myself (winter school).
- December 7, 2016, I will give a lecture titled 'Studying network entry and exit in a dynamic communication network' at the Communicative Figurations conference taking place at the University of Bremen. My host will be Thomas Friemel.
- October 27, 2016, I contributed a lecture titled 'Gender differences in networks of adolescents' and was part of the panel at the International Workshop & Panel Discussion on Social Networks & Gender at the GenTIC research group of the Universitat Oberta de Catalunya in Barcelona. Organisers were Jörg Müller and Natalia Garrido.
- October 13, 2016, I contributed a lecture titled 'Network Analysis' to the meeting Causal inference and network analyses in register-based research of the Swedish Initiative for Research on Microdata in the Social and Medical Sciences (SIMSAM). The meeting took place at the Norrköping campus of Linköping University; the organisers were Catarina Almqvist Malmros and Peter Hedström.
- April 5, 2016, I gave a presentation titled 'Assessing peer influence with panel data: Models and designs' at the Amsterdam School of Communications Research of the University of Amsterdam. My host was Wouter de Nooy.

How I came here
My first academic education was a study of mathematics and information science at
the TU Berlin.
Not wanting to spend my life proving theorems or optimising some company's profits, I got enticed with the idea of applying mathematical thinking and modelling in the still thoroughly underformalised social sciences. The opportunity to do so came when the ICS Research School accepted me as a Ph.D. candidate. My thesis project was about the stochastic modelling of cultural and situational context effects on individual decision making. The resulting dissertation entitled The Framing of Decision Situations was defended 18th of September, 2003. Since 2002 I have been working on social networks, beginning with an NWO-funded Dutch national project ('aandachtsgebied') on co-evolving social networks and behaviour. I am grateful for Tom Snijders' mentorship throughout these years!
