Important changes in the school go into effect July 1, 2009: The IUB part of the school is now named School of Informatics & Computing and we won’t have internal departments (CS and Informatics) anymore. Faculty will be organized in three internal, transparent (invisible), anonymous divisions. I chair one of these, internally referred to as divA (we are divA faculty)… Seriously, I hope this will help us market our brand better for its breadth, attract more students, improve our ranking, and get rid of some arbitrary/historical internal barriers to innovative curriculum and interdisciplinary research.

The Center for Complex Networks and Systems Research (CNetS) is part of the Pervasive Computing Institute of Indiana University and the School of Informatics and Computing. The center was established in 2009 to consolidate and enhance the research efforts of the complex systems group, which has been active within the School since 2004. CNetS is meant to foster interdisciplinary research in all areas related to complex systems. It is currently under the direction of Alessandro Vespignani, Rudy Professor of Informatics, Physics, and Statistics.

CNetS embodies mathematicians, physicists, biologists, psychologists, cognitive scientists, information scientists, linguists, and computer scientists, emphasizing lively and multidisciplinary teamwork with other research groups within the university, in the US and abroad. For example, within IU we presently have joint collaborations with the Cognitive Science Program, the Biocomplexity Institute, the School of Library and Information Science, the Department of Psychological and Brain Sciences, the Center for Data and Search Informatics, and other groups within Informatics. Outside IU, CNetS is part of the Complex Networks Collaboratory together with the Complex Networks Lagrange Laboratory at the Institute for Scientific Interchange in Torino, Italy, and the Centre de Physique Théorique at the University of Marseille, France. CNetS is also affiliated with the FLAD Computational Biology Collaboratorium at the Instituto Gulbenkian de Ciencia in Lisbon, Portugal.

The types of problems that we work on include mining usage and traffic patterns in technological networks such as the Web and the Internet; studying the interaction between social dynamics and online behaviors; modeling the evolution of complex social and technological networks; developing adaptive, distributed, collaborative, agent-based applications for Web search and recommendation; understanding complex biological networks and complex reaction in biochemistry; developing models for the spread of diseases; understanding how coordinated behavior arises from the dynamical interaction of nervous system, body, and environment; studying social human behavior; exploring reasons underlying species diversity; studying the interplay between self-organization and natural selection; understanding how information arises and is used in biological systems; and so on. All these examples are characterized by complex nonlinear feedback mechanisms and it is now being increasingly recognized that the outcome of such interactions can only be understood through mathematical and computational models.

We have a wonderful computing infrastructure to support some of our projects. CNetS research is funded by a number of agencies, including:

Lilly Endowment Inc.

National Science Foundation

National Institutes of Health

IU Office of the Vice Provost for Research

School of Informatics and Computing

The Talk Series on Networks and Complex Systems organized by Katy Börner is every Monday 6-7p in Wells Library 001 during the academic year. Talks are open to all Indiana University faculty and students interested in network analysis, modeling, visualization, and complex systems research. A major intent is to cross-fertilize between research done in the social and behavioral sciences, research in natural sciences such as biology or physics, and research on Internet technologies.
