Background
Dr. Trey Roady holds a Ph.D. in Interdisciplinary Engineering with an emphasis in Human Factors & Cognitive Systems from Texas A&M University and is a board-certified Human Factors Professional. His Ph.D. research investigated the use of vibrating interfaces to support decision-making under mental workload for both individuals and cooperative pairs. After completing his Ph.D., he was employed by Seeing Machines, Canberra, Australia, where he provided scientific and design support in addressing operator fatigue and distraction in commercial truck fleets and pilots.
Dr. Roady investigates how distraction, drowsiness, chemical impairment, and emotional state affect fitness to operate for fleet truckers, pilots, and drivers. He helped author the current industry validation standards for driver monitoring systems (DMS) in retail automotive; assisted in the design and validation of said DMS found in the Ford Blue Cruise, GM Super Cruise, and Mercedes Benz S-Class vehicles; designed algorithmic implementations for the award-winning, 3rd-generation Guardian fleet truck monitoring service; and shaped international hours-of-service regulations in fleet trucking and automation-assisted driving. His expertise is broadly defined as human factors and cognitive systems engineering, including analysis of visual, auditory, and vibration perception; attention and gaze behavior; cognitive workload; age; lighting and visibility; response time; automation transparency; augmented/virtual reality; decision making processes; and the impact of lighting and temperature on circadian rhythms.
Dr. Roady also has experience in industrial safety. He’s taught course material on facility design and material handling and had experience with topics such as statistical quality control, repetitive stress injuries, lifting, fall safety, lighting, and heat stress.
