Carley’s research combines cognitive science, social networks, and computer science to address complex social and organizational problems.


Carley specializes in network science, agent-based modeling and text-mining within a complex socio-technical system, organizational and social theory framework. In her work, she examines how cognitive, social and institutional factors come together to impact individual, organizational and societal outcomes. Using this lens, she has addressed a number of policy issues including counter-terrorism, human and narcotic trafficking, cyber and nuclear threat, organizational resilience and design, natural disaster preparedness, cyber threat in social media, and leadership. Carley is the director of the Center for Informed Democracy and Social Cybersecurity (IDeaS), which is focused on fighting the spread of online disinformation. She also serves as the director of the Center for Computational Analysis of Social and Organizational Systems (CASOS), a university wide interdisciplinary center that brings together network analysis, computer science, and organization science. She has served as a task force member of the Defense Science Board and committee member on the Department of Homeland Security Science and Technology. She is the developer of the ORA software for network analytics and visualization that is widely used in academics, organizations and government.
