The dates for the 2018 CASOS Summer Institute will be June 10th through 16th at the Gates/Hillman Complex at Carnegie Mellon University. Registration is now open, visit the 2018 Summer Institute Page for more details.

Welcome to Center for Computational Analysis of Social and Organizational Systems (CASOS)!


Addressing complex real world issues through a combined social-science & computer-science approach, using advanced techniques from network science, text-mining, and agent-based modeling.

  • Leader in network science, network analysis and network visualization.
  • Leader in network dynamics and linking social networks to other data - geo-spatial, knowledge, tasks etc.
  • Leading analytic tools for network analysis - ORA-LITE, AutoMap, Construct
  • University wide center with faculty and students in multiple departments
  • Multi-disciplinary research - working with Academia, Industry, Government
  • Applications related to Law Enforcement, Counter-terrorism, Health, Nuclear Deterrence, Cyber-Security, Social Change, Organizational Design, Insider Threat, Population Dynamics, Social Media.

Director: Prof. Kathleen M. Carley
