Professor Carley specializes in organization theory, dynamic network analysis, social networks, multi-agent systems and computational social science. In her work, she examines how cognitive, social and institutional factors affect individual, team, social and policy outcomes in a wide variety of areas including command and control, counter-terrorism, counter-narcotics, organizational design, corporate mergers and leadership. She is the author or co-author of 9 books and over 100 articles in the area of computational social and organizational science and dynamic network analysis. Recent publications include - Designing Stress Resistant Organizations: Computational Theorizing and Crisis Applications with Zhiang Lin (Boston, MA: Kluwer, 2003); Behavioral Modeling and Simulation: From Individuals to Societies (Washington, DC: National Academy Press); Dynamic Social Network Modeling and Analysis: Workshop Summary and Papers with Ron Breiger and Pipp Pattison (Washington, DC: National Academy Press, 2003); Findings from an organizational network analysis to support local public health management, 2008 with Jacqueline Merrill, Michael Caldwell, Maxine L Rockoff, Kristine Gebbie, and Suzanne Bakken, (Journal of Public Urban Health.

Professor Carley has served on multiple National Research Council panels related to computer simulation, various National Science Foundation committees, and as a task force member for the Defense Science Board.
She is a member of the Academy of Management, Informs, International Network for Social Networks Analysis , American Sociological Society, the American Association for the Advancement of Science and Sigma XI, and the North American Association for Computational Social and Organizational Science (founding president). In 2001 she received the Lifetime Achievement Award from the Sociology & Computers Section of the ASA. She is a founding and the current editor of the journal Computational and Mathematical Organization Theory.

Research Interests

Her research combines cognitive science, social networks and computer science to address complex social and organizational problems. Her specific research areas are dynamic network analysis, computational social and organization theory, adaptation and evolution, text mining, and the impact of telecommunication technologies and policy on communication, information diffusion, disease contagion and response within and among groups particularly in disaster or crisis situations.
She and her lab have developed infrastructure tools for analyzing large scale dynamic networks and various multi-agent simulation systems. The infrastructure tools include ORA, a statistical toolkit for analyzing and visualizing multi-dimensional networks. ORA results are organized into reports that meet various needs such as the management report, the mental model report, and the intelligence report. Another tool is AutoMap, a text-mining system for extracting semantic networks from texts and then cross-classifying them using an organizational ontology into the underlying social, knowledge, resource and task networks. Her simulation models meld multi-agent technology with network dynamics and empirical data. Three of the large-scale multi-agent network models she and the CASOS group have developed in the counter-terrorism area are:
BioWar a city-scale dynamic-network agent-based model for understanding the spread of disease and illness due to natural epidemics, chemical spills, and weaponized biological attacks; DyNet a model of the change in covert networks, naturally and in response to attacks, under varying levels of information uncertainty; and RTE a model for examining state failure and the escalation of conflict at the city, state, nation, and international as changes occur within and among red, blue, and green forces. Dr. Carley is the director of the center for Computational Analysis of Social and Organizational Systems (CASOS) which has over 25 members, both students and research staff. She is the founding co-editor with Al. Wallace of the journal Computational Organization Theory and has co-edited several books in the computational organizations and dynamic network area.
