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

Since 2009, GROUPER work related to cybersecurity has emphasized research to describe and quantitatively analyze information alignment and problem solving in distributed expertise networks.  This research has included computer simulation models of expertise coordination and problem solving, as well as field research involving interviews with cybersecurity analysts to identify and address gaps in incident response team performance.  Based on CERIAS funding for the project, Information Presentation to Support and Enhance Analyst Situation Awareness and Event Response in Cyber Network Operations Centers, PhD student O. Eldardiry completed his dissertation, "IMPROVING INFORMATION ALIGNMENT AND DISTRIBUTED COORDINATION FOR SECURE INFORMATION SUPPLY CHAINS" in May 2018.  M. Nyre-Yu completed her dissertation, "DETERMINING SYSTEM REQUIREMENTS FOR HUMAN-MACHINE INTEGRATION IN CYBER SECURITY INCIDENT RESPONSE" in December 2019.
