LITTLE ROCK, Ark. — Dr. Nitin Agarwal, Maulden-Entergy Chair and Donaghey Distinguished Professor of Information Science at the University of Arkansas at Little Rock, has received a $5 million research award from the U.S. Department of War to advance socio-computational methods for mitigating cognitive attacks and strengthening community resiliency in digital environments.
Through the project, titled “Developing Socio-computational Methods to Strengthen Community Resiliency to Mitigate Cognitive Attacks,” Prof. Agarwal, founding director of the Collaboratorium for Social Media and Online Behavioral Studies (COSMOS) Research Center at UA Little Rock, and his team will advance their groundbreaking work in understanding and mitigating cognitive threats in the digital age.
The award was championed through support from U.S. Sen. John Boozman, who continues to be a strong advocate for the innovative, cutting-edge research taking place at UA Little Rock and COSMOS.
“I am pleased to support UA Little Rock and its Collaboratorium for Social Media and Online Behavioral Studies. This award recognizes the significance of this program to our national security,” Boozman said. “The important research conducted here will enhance our ability to counter the use of novel social media tactics by foreign extremists and terrorist groups threatening the United States and our allies.”
“We are extremely grateful for the support from UA Little Rock leadership and U.S. Sen. John Boozman for championing this vital research,” Prof. Agarwal said. “This funding helps COSMOS Research Center continue to develop analytical tools and capabilities to strengthen our national defense and security apparatus against cognitive threats.”
The research addresses the growing threat posed by coordinated adversarial influence operations, online extremism, and other forms of cognitive warfare conducted through social media and digital platforms. As online narratives increasingly shape perceptions, behaviors, and societal cohesion, the project seeks to develop science-driven approaches to understand, predict, and mitigate harmful information campaigns before they escalate into real-world consequences.
“Social media has evolved into a contested cognitive battlespace where narratives can be weaponized to manipulate beliefs, sow discord, and influence collective behavior at unprecedented speed,” said Prof. Agarwal. “This project aims to strengthen community resiliency by developing computational methods that help identify harmful narrative dynamics early, understand how they spread across networks, and inform effective intervention strategies.”
The project will advance socio-computational science through six major research thrusts: modeling narratives and networks, modeling toxicity in online communities, understanding mob dynamics, churn analysis, contextual network characterization, and large-scale data collection and dashboarding.
Researchers will develop multimodal approaches to extract and analyze narratives across digital ecosystems, including how narratives evolve through merging, splitting, and mixing over time. The project will also examine the co-influence between narratives and social networks to better understand how online communities amplify coordinated campaigns.
A key component of the effort involves adapting epidemiological modeling techniques to study the spread of toxicity online, similar to modeling varying levels of infection in public health systems. These models will support science-driven decision-making related to intervention strategies and community health in digital spaces.
The research will further investigate the formation and diffusion of online mobs and coordinated collective behavior, enabling simulations that identify favorable and unfavorable conditions for mobilization. Additional efforts will focus on churn analysis to understand participant dynamics in influence campaigns and determine whether campaigns are approaching critical mass.
The project also includes the development of interoperable data collection and analytics frameworks that integrate multiple streams of information into standardized formats for rapid dashboarding and operational analysis. These tools are intended to support policymakers and decision-makers with near-real-time situational awareness and predictive analytics capabilities.
In addition to advancing research, the initiative will support workforce development and training activities in big data analytics, machine learning, artificial intelligence, and security applications, helping strengthen the future AI and security workforce in Arkansas and beyond.
The award continues the longstanding partnership between Prof. Agarwal’s COSMOS Research Center and the U.S. Department of War in advancing research at the intersection of artificial intelligence (AI), social computing, and national security, specifically in the cognitive domain.
The COSMOS Research Center at the University of Arkansas at Little Rock conducts interdisciplinary research focused on social computing, AI-enabled socio-cognitive threat mitigation, narrative analytics, online behavioral modeling, and cognitive security.
