AFRL researcher wins Harold Brown Award Published Dec. 13, 2006 By AFRL Human Effectiveness Directorate WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- Dr. John A. Caldwell, a principal research psychologist with AFRL's Human Effectiveness Directorate, was honored with the 2005 Harold Brown Award, the Air Force Materiel Command's highest honor for significant contributions in the field of research and development. Recipients of the Harold Brown Award are chosen by the chief scientist of the Air Force. The award honors researchers who make a substantial improvement to the Air Force's operational effectiveness. This prestigious award honors Dr. Caldwell's accomplishments and vast expertise in the field of experimental psychology and confirms the world-class talents of AFRL's scientists and engineers. Dr. Caldwell, a member of AFRL since 2002, received the award for his outstanding science and technology research for improving human weapon system safety and effectiveness. Dr. Caldwell led a diverse team in designing and conducting--and subsequently transitioning the results of--the only scientific investigations that have successfully quantified fatigue impact and associated countermeasures on pilot performance. He demonstrated a 50-70 percent flight performance increase with a new fatigue countermeasure and rapidly transitioned these results to operations as policy guidance and preventive measures for mitigating operational fatigue related to the warfighter. Dr. Caldwell's scientific findings enabled safe, effective pilot performance in sustained operations during Operations Enduring and Iraqi Freedom.
