The Applied Behavioral Biology Unit (ABB), directed by Dr. Pete Roma, focuses on experimental investigations of environmental, psychosocial, and biological factors relevant to behavioral health and operational performance in individuals and groups.

The ABB is supported primarily by a grant from the National Aeronautics and Space Administration (NASA), and focuses on cooperative behavior, team performance and cohesion, and biopsychosocial adaptation over time in laboratory, field, and operational environments.  Recent studies have also explored the interactions between circadian phase, extended workload, and task autonomy on performance, stress physiology, and cooperative behavior in long-term work groups.
