SIENA research projects
The SIENA program is itself the product of an ongoing research effort. The research team is composed of Tom Snijders, Christian Steglich, Ruth Ripley, Johan Koskinen, and Krists Boitmanis, with contributions from Michael Schweinberger, Mark Huisman and Marijtje van Duijn. The computer implementation is reflected by the StOCNET program, which is an environment from which SIENA can be executed; although it is also possible to execute SIENA as a stand alone program. The StOCNET project is an activity of Christian Steglich, Tom Snijders, and SciencePlus (Bert Straatman), with important earlier contributions from Evelien Zeggelink, Peter Boer, Mark Huisman, and others.
During 2002-2008 a research program The dynamics of networks and behavior was active, in cooperation between researchers of the universities of Groningen and Utrecht (graduate school ICS) and Maastricht (dept. of Health Promotion and Health Education). In this research program, the methodology used in SIENA is being extended to methods for analyzing the joint dynamics of networks and of individual behavior, and applied to several sociological research questions.

During 2006-2010 an international research program Dynamics of Actors and Networks across Levels: Individuals, Groups, Organizations, and Social Settings is active, in cooperation between researchers of the universities of Groningen and Oxford, Konstanz, Paris-Dauphine, Barcelona (Autonomous University) and Sevilla, Orebro,Lugano (University of Italian Switzerland), and Cardiff. This is a European Collaborative Research Project in the EUROCORES scheme of the ESF. This research program extends and applies the methodology used in SIENA.

As part of the project Adolescent Peer Social Network Dynamics and Problem Behavior, funded by NIH (Grant Number 1R01HD052887-01A2), Principal Investigator John M. Light (Oregon Research Institute), SIENA is being reprogrammed entirely. This is being done by Ruth Ripley and Krists Boitmanis, collaborating with Tom Snijders and Johan Koskinen. The new version is SIENA 4, also called RSiena. The first official version was released late June, 2009. As the functionalities in SIENA will be added step by step, for some time both SIENA 3 and SIENA 4 will be supported.
