Group Performance Environments Research (GROUPER) Lab

Research Areas: Human Centric Security

Principal Investigator: Barrett Caldwell

Prof. Caldwell’s research program is known as the Group Performance Environments Research (GROUPER) Laboratory.  GROUPER research examines human factors engineering aspects of information flow, task coordination, and team performance as affected by information technology.  GROUPER applies human factors engineering principles to improve how people get, share, and use information well

Prof. Caldwell's projects since 2005 have included development of models and analyses of human distributed expertise for NASA Centers including Jet Propulsion Lab, Johnson Space Center, Kennedy Space Center, and Marshall Space Flight Center. GROUPER work in this area has addressed new concepts in distributed mission operations, including human factors based simulation of problem solving among teams distributed with respect to physical, temporal, or knowledge domains. 

GROUPER completed a funded CERIAS project, Information Presentation to Support and Enhance Analyst Situation Awareness and Event Response in Cyber Network Operations Centers .  The project is ongoing, although inital CERIAS funding has ended.
