Dr. George Calhoun reviews information with a research assistant in the high-tech finance lab at Stevens.
Research at Stevens seeks to both advance knowledge and provide practical solutions in industry.

Researchers in this area study cognition by conducting human behavioral experiments and developing computational models that explain the observed behaviors. Based on the results from human experiments and computer simulations, researchers develop adaptive systems or machines that display effective learning in varying environments, and devise decision and training aids that improve people's performance.

One application of this work is detecting hostile intent in time to prevent attacks. Researchers are particularly interested in asymmetric situations, in which individuals or small teams are potential attackers. Human movement may reveal intent early enough to allow for interception; work at the center is finding that movement patterns can provide early clues about an intended destination, even if the subject is trying to deceive.

A primary goal of this work is to apply the understanding of human cognition to help solve real-world problems, such as detecting hostile intent, distributing sensors, understanding social networks and improving education.
