## Social networks

Snijders is a prominent researcher in the field of statistic methods in behavioural and social sciences. In 1998, together with others, he created Stocnet, an open software system for the advanced statistical analysis of social networks. Snijders is working especially in social network analysis: statistical methods for analysing social networks and in network evolution, in social science, mathematical sociology and mathematical response theory, and also in multilevel models analysis, about which he wrote a textbook, titled Multilevel Analysis. An Introduction to Basic and Advanced Multilevel Modeling (1999). Apart from this he developed new statistical methods for social science applications, often in combination with the development of computer software to implement these methods. Together with professor Patrick Doreian of the University of Pittsburgh Tom Snijders edited the international scientific journal Social networks. An international journal of structural analysis.
